Info popup shows up black #17

Open Kinematics opened 5 years ago

Kinematics commented 5 years ago

The info popup that gives network information shows up with a black background most of the time, making it basically unreadable. Repeated attempts to open the popup will eventually provide a non-blacked out version, but it's only temporary.

Using this on Windows 7, Firefox 71 nightly, Sept 28 build.

Hi there, does this happen for you also on the latest production/release build of Firefox on the same system? I've had reports before of this happening on nightly builds but never on a release build, which leads me to think it might just be a transient issue with some nightlies?

I installed the full release version of Firefox (69.0.2). It seemed to work the first couple tries, but the list reminded me that I really needed uBlock Origin installed. After installing that addon as well, the 6orNot results were normal on the first attempt, then a preliminary black background that restored itself to white on the second attempt, and then a full black background that stayed that way on the third attempt.

In case that was an interaction with uBlock Origin, I disabled it and tried again. Same result.

And just to make sure it returned to the base state, I restarted Firefox.

Repeatedly hitting the 6orNot button gave about 80% black background to 20% white background, at random.

The new install of Firefox used the Default theme, while my personal install uses the Light theme. I'm on Windows 7, with Aero active but non-transparent. I'm not sure what else could potentially affect draw style.

I can attempt to run a profiler during the popup activation (using the extension from profiler.firefox.com), though I'm not sure if it will provide any useful information.

Here's a profile run on Firefox release. It was a single click of the toolbar button, and the background showed up black. You can load it on https://profiler.firefox.com/ after installing the extension, using the load from file option. (The "load from permalink URL" doesn't seem to work properly because of cross-site restrictions.)

Firefox 2019-10-03 16.40 profile.json.gz

I have no idea how useful this will be in tracking down the problem, but it at least shows everything the addon is doing.

Thank you for so much detail! I'm going to have to do some digging to try and figure this one out, the sixornot popup/panel should in theory just be rendering itself essentially as a webpage, but the context that addons run in is a bit weird. I'll see what I can do.
