Use latest Firefox version with Selenium 2 on GitHub Actions

[aik099]

The https://hub.docker.com/r/selenium/standalone-firefox image provided by Selenium only supports Firefox 47 when used with Selenium server 2.x versions. This causes problems in a test suite because a working code (e.g. dragging a div into itself in #359) fails due:

• either outdated Firefox version
• either outdated geckodriver version

Need to create an image with a modern Firefox/geckodriver version and use it on GitHub Actions.

@aik099 @mvorisek @stof unfortunately, the request to update the firefox-se2 image was understandably not so successful.

I think I could be able make such a docker image with the pointers they provided, but that leaves a few open questions:

1. do we really want to keep supporting Se2? Part of the reason to turn down the request is that all components are considered outdated and unsupported by the vendors (selenium, mozilla browser/driver..). Just want to point that out, I'm fine either way.
2. where do we store the image? I'm thinking we could have a GH repo + workflow that generates and stores that image.
3. this will impact docker-compose files and workflows that assume the image looks like `selenium/standalone-:``- they'll need to handle the first part as well, in this case.

[aik099]

1. What will be the file size of the built docker image?
2. The BrowserStack use Selenium Server 2 by default. I guess we need to support Selenium 2.

@aik099

1. What will be the file size of the built docker image?

Probably at least 244mb - that's the current size of the image. That's well below GitHub's container registry limits.

2. The BrowserStack use Selenium Server 2 by default. I guess we need to support Selenium 2.

Understood.

To answer your question from the other issue, my first thought is to create a new repo with just a workflow that generates and pushes such an image to the GitHub registry, which we can use later. We could make this a bit more generic to allow adding more custom browser images - say opera or so, if we ever need that.

[aik099]

That's good news. So GitHub has a place to store Docker images and we have image-building instructions from @SeleniumHQ. This way we can have mini-version of Selenium Docker images without our own tagging system.

Interesting sub-project.

Some docs I've found: https://docs.github.com/en/actions/use-cases-and-examples/publishing-packages/publishing-docker-images - how to push container image to container registry upon release

Not sure if we should clone https://github.com/SeleniumHQ/docker-selenium/tree/trunk or do something else.

[aik099]

I've playing around with Docker to see if I can manage to build an image using instructions from https://github.com/SeleniumHQ/docker-selenium/issues/2454#issuecomment-2453550659 .

The build succeeded with below patching instructions:

git clone git@github.com:SeleniumHQ/docker-selenium.git
cd docker-selenium
git checkout refs/tags/2.53.1-beryllium
make generate_all

# in the "NodeBase/Dockerfile.txt" add this line after 'ENV TZ "US/Pacific"'
RUN apt-get update && DEBIAN_FRONTEND=noninteractive TZ=Etc/UTC apt-get -y install tzdata

# in the "NodeFirefox/Dockerfile.txt" change
- firefox version to 88.0
- geckodriver version to 0.29.1

BUILD_ARGS="--platform linux/amd64" make standalone_firefox

Then you can create a container using just built image and don't forget to map 4444:4444 port in that container.

The selenium server in container does start, but when I attempt to operate on Firefox from it I'll get timeout error:

The error suggests, that I haven't properly matched Selenium Server to the Geckodriver version and Firefox version (as said in https://www.edureka.co/community/5548/unable-to-connect-to-host-127-0-0-1-on-port-7055-after-45000-ms ).

The same thing happens if I try to use --headless flag in the desired capabilities.

A super easy reproduction example would be to create this Dockerfile in an empty folder:

FROM selenium/standalone-firefox:2.53.1-beryllium

USER root

RUN apt-get update

And then run docker build --platform=linux/amd64 . in that folder.

This will get you the most recent Firefox version (88.0), that is compatible with this os. Probably I need to install something to make it work, but I have no idea what exactly.

[uuf6429]

Sorry to hear it didn't work out, but good to see some progress nevertheless.

What confuses me in your (final) instructions is that it seems to upgrade firefox after running apt-get update... surely that can't be right? 🤔

[aik099]

Sorry to hear it didn't work out, but good to see some progress nevertheless.

It's work in progress. At least it's not a compilation error, that I saw at beginning.

What confuses me in your (final) instructions is that it seems to upgrade firefox after running apt-get update... surely that can't be right? 🤔

What is wrong wrong with this? You mean we're not controlling what Firefox version is used and getting the latest compatible to the OS?

Did another try to build an image with same Firefox/geckodriver versions as it's supposed to be built. It doesn't work either, but the error is different:

Could not open connection: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox console output:
XPCOMGlueLoad error for file /opt/firefox-47.0.1/libxul.so:
libasound.so.2: cannot open shared object file: No such file or directory
Couldn't load XPCOM.

Now I've tried looking at the build warnings I've received and turned out some of Dockerfile syntax (like ENV var_name var_value) is deprecated, but in reality it simply has no effect. After fixing it and adding couple of missing packages (instructions below) I've managed to get original image to build (with old firefox version):

git clone git@github.com:SeleniumHQ/docker-selenium.git
cd docker-selenium
git checkout refs/tags/2.53.1-beryllium
make generate_all

# replaced "ENV var_name var_value" into "ENV var_name=var_value" in these files:
#- NodeBase/Dockerfile.txt
#- NodeFirefox/Dockerfile.txt

# in the "Base/Dockerfile" added "libasound2 \" (on a new line) after "wget \"
# in the "Base/Dockerfile" added "tzdata \" (on a new line) after "libasound2 \"

# in the "NodeFirefox/Dockerfile.txt" change (still experimenting what versions will work)
- firefox version to 130.0 or 88.0.1
- geckodriver version to 0.35.0 or 0.29.1

I've also tried using 3.141.59-zirconium tag and replaced Selenium Server version used. The commands are as follows:

git clone git@github.com:SeleniumHQ/docker-selenium.git
cd docker-selenium
git checkout refs/tags/3.141.59-zirconium

# in the "Base/Dockerfile" replaced "https://selenium-release.storage.googleapis.com/3.141/selenium-server-standalone-3.141.59.jar" with "https://selenium-release.storage.googleapis.com/2.53/selenium-server-standalone-2.53.1.jar"

# in "Standalone/start-selenium-standalone.sh" file replace the

java ${JAVA_OPTS} -cp ${JAVA_CLASSPATH:-"/opt/selenium/*:."} org.openqa.grid.selenium.GridLauncherV3 \
    ${SE_OPTS}

with

java ${JAVA_OPTS} -jar /opt/selenium/selenium-server-standalone.jar \
    ${SE_OPTS}

While connected via VNC I've seen, that Selenium does start Firefox and then does nothing for 45 seconds and then closes firefox (or firefox crashes).

⚠️ The [...](glxtest: libpci missing) error can be solved with sudo apt-get install pciutils command, but I wasn't able to figure out what package needs to be installed to fix the glxtest: libEGL missing error.

[stof]

another option is to stop using a docker image for that in our CI process, installing Selenium and Firefox separately in the GHA runner (and Firefox is even pre-installed in the runner image: https://github.com/actions/runner-images/blob/main/images/ubuntu/Ubuntu2204-Readme.md#browsers-and-drivers)

We did that in the past (in Travis CI times). I don't remember why we've decided to abandon that approach in favor of a selenium Docker image.

[stof]

I think we did that in GHA because it was simpler to setup (but this is simpler only as long as we have maintained images)

[uuf6429]

installing Selenium and Firefox separately in the GHA runner

You know that the runner is basically docker? You can just copy&paste those commands into a new Dockerfile and we're ready to go.

The selenium repo setup might have been nice if it was quick and fast, but it turns out it isn't. That doesn't mean we throw away all (selenium) images and docker even, just because of that.

I don't remember why we've decided to abandon that approach

Uhm, let's see...

1. because it works differently than local, even if you happen to be using linux
2. it's very slow to set up
3. it's impossible to share between devs... it might work on macs, but it won't on windows ('coz who cares about those devs, right?)
4. it's extremely high maintenance... some package firefox depends on changes and suddenly you're building libxxxxx manually
5. you're forced to be a browser expert...firefox needs this and that, opera needs that other thing etc
6. setting up a matrix is a breeze, you just fill in the browser name/version and you're done

[aik099]

If Selenium 2/3 won't work on the latest GitHub Actions machine, then we're forced to stay with Docker.

Here is the summary of my reanimation experiments on Selenium 2 Docker images:

• they are pretty fragile (you only need to update Firefox above 49.0.2 version and everything stops working)
• Firefox itself opens just fine (tested via VNC)
• when Selenium 2 (either installed on 3.141.59-zirconium or used from 2.53.1-beryllium) attempts to control Firefox it only is able to start it and freeze for 45 seconds without the ability to control it; then Firefox closes by itself

I even was able to run Selenium 3 inside a 2.53.1-beryllium container without issues. Maybe I need Java > 1.8.0, that is available on Ubuntu 16 being used?

@uuf6429 , any idea how to overcome this problem?

[uuf6429]

@aik099 I'm sorry I didn't have time yet to deep dive into this.

Yesterday I tried a simple dockerfile (based on your short example above) and was trying to analyse the last layer (apt-get update), but the usual tools I use both failed (dive is quite broken (and apparently abandoned) and PhpStorm/IDEA is also currently broken 🤦).^

I'm well aware of Docker's advantages - it's a far cry from vagrant and pre-built VMs, but it's also not the most polished tool out there. I deeply resent that, especially the way they treat their users, but I'm not aware of a good alternative.

[aik099]

@uuf6429 , were you able to get Docker image build with latest Firefox and Selenium 2 and see these errors?

Here is latest patch to be applied over 2.53.1-beryllium tag:

Yesterday I tried a simple dockerfile (based on your short example above) and was trying to analyse the last layer (apt-get update), but the usual tools I use both failed (dive is quite broken (and apparently abandoned) and PhpStorm/IDEA is also currently broken 🤦).^

I've used Docker Desktop and "SSHed" into the container using Bash to see what's happening inside any trying to do different stuff.

[uuf6429]

The idea behind dive/analysis was to see exactly what changed in the apt-get update layer.

Mostly because I was confused from what you said, that running apt-get update would update firefox, since AFAIK only apt-get upgrade actually updates apps/libs (the other one just updates catalogs/indexes).

Anyway, I'll give this a look later on today.

[aik099]

The idea behind dive/analysis was to see exactly what changed in the apt-get update layer.

Upgrading existing packages doesn't break anything OS-wide (the new Firefox version after the upgrade works by itself).

It's something that Selenium Server 2 does to communicate with Firefox, which causes a problem on Ubuntu specifically. We can almost be certain about this because Selenium Server 3 is working just fine with the same Firefox version on the same container, whereas Selenium Server 2 doesn't.

I know for sure, that Selenium Server 2 on macOS does work with Firefox 130.0.2. This proves once again, that it's a Ubuntu-specific issue, that needs to be uncovered.

Mostly because I was confused from what you said, that running apt-get update would update firefox, since AFAIK only apt-get upgrade actually updates apps/libs (the other one just updates catalogs/indexes).

Maybe it was a typo (usage of apt-get update instead of apt-get upgrade) considering comment writing time (late evening) and my unfamiliarity with the Ubuntu package manager. My apologies for the confusion it caused.

[uuf6429]

My apologies for the confusion it caused.

No problem at all.

On that point, that's also an aspect of Docker that I like - I tend to avoid manual changes/adjustments and keep iterating on the Dockerfile since in theory it should guarantee consistency (and I know that I can simply share that file with other people).

[uuf6429]

I've set up a mostly working (builds & stuff connects) Dockerfile, however something seems to break (seems consistent with the earlier comment). Here are the test results:

Firefox	Geckodriver	Selenium	Results
47.0.1	0.14.0	2.53.1	D&D Test Fails
47.0.1	0.35.0	2.53.1	D&D Test Fails

This seems consistent with claims like: https://groups.google.com/g/selenium-developers/c/d8KpXpmDp2g?pli=1 as well as the releases notes for geckodriver v0.15.0 and v0.16.0. That said, there were reports in the past that the port 7055 problem could be related to unsigned extensions or so - I haven't played with that yet.

Hmm, I've found some additional details:

1. Selenium 2 supports Firefox up to version 47, through the builtin FirefoxDriver.
2. Firefox 48 and newer requires geckodriver and Selenium 3 to work correctly.

It's unclear to me in which case geckodriver <0.15.0 would have made sense.

---

I think at this point I'd consider simply disabling (or ignoring-failures of) the firefox-on-selenium2 build (or at least, the failing D&D test). The chrome build is good enough and it should be clear to end users that selenium 2 is greatly outdated and therefore there will be some lack of support.

Maybe all these restrictions apply on Ubuntu (Linux)? I've justed executed test testDragDropOntoHiddenItself test using BrowserStack on Selenium Server 2.45.0 + Firefox 130.0 + Windows 10.

I'm wondering why this works on both Mac and Windows, but not on Linux.

[uuf6429]

I don't fully understand your setup. So you mean that behat/mink + selenium is on your local machine and Firefox is on Windows in browserstack?

Would it be possible to find me the exact capabilities being sent?

[aik099]

• The Web Server is on my Machine.
• I start test suite on my machine.
• Selenium Server and Firefox and OS, where Firefox runs are on the BrowserStack side.
• I'm using BrowserStackLocal app to create tunnel between my computer and BrowserStack so that it can open URLs, that are accessible only from my local network.
• In the \Behat\Mink\Tests\Driver\Selenium2Config::createDriver method I've added this code (the 2nd argument are desired capabilities):

  return new Selenium2Driver(
          'firefox',
          array(
              'build' => 'MinkSelenium2Driver Tests - Selenium2 Setting Detection',
              'browserstack.local' => 'true',
              'browserstack.localIdentifier' => 'nativeapp:...',
              'acceptInsecureCerts' => true,
              'version' => 131,
          ),
          'http://username:api_key@hub.browserstack.com/wd/hub'
      );

• then in \Behat\Mink\Driver\Selenium2Driver::start method after connection is made I'm doing $this->webDriver->status() to get Selenium version being used.

The desired capabilities, that BrowserStack receives are as follows:

browserName: firefox
name: Behat Test
build: MinkSelenium2Driver Tests - Selenium2 Setting Detection
version: 131
acceptSslCert: true
browserstack.seleniumLogs: true
localVersion: 8.9
browser: firefox
browser_version: 131
browserstack.tunnel: true
browserstack.tunnelIdentifier: nativeapp:...
browserstack.local: true
browserstack.localIdentifier: nativeapp:...

I tried a few combinations and ideas without success. My guess in that set up is that Browserstack is doing something to restore compatibility - either by somehow hacking up selenium or geckodrive or perhaps installing some extension in firefox to replace the old FirefoxDriver. Maybe check the exact versions of those and then check if firefox has any special extensions set up?

Finally, I tried a Docker-less setup on my Windows machine with Selenium 2, Firefox 132 and Geckodriver 0.35.0 and I pretty much got the same error (Firefox did indeed start):

org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox console output:

Double-checking on Windows 11 (in VM) locally + Selenium 2 + newer Firefox + Geckodriver 0.35.0 resulted in the same 45000 ms timeout.

So obviously BrowserStack is doing something to make Selenium 2 work with newer Firefox versions, that regular developers can't do. This means we shouldn't even support Selenium 2 with newer Firefox browser versions, because it can't work.

@uuf6429 , Let's instead focus on attempting to exclude that testDragDropOntoHiddenItself test for Selenium 2 + Firefox to make the test suite green again.

We can likely skip that test based on the SELENIUM_VERSION and WEB_FIXTURES_BROWSER environment variables in the \Behat\Mink\Tests\Driver\Selenium2Config::skipMessage method.
