Unable to install on 41.0a2 (2015-08-04)

[citosid]

I just downloaded the newer version of firefox (fresh isntall of mac) and it does not allow me to install the version 3.

[citosid]

@janodvarko Is there any way to force the installation? I really need this to work as soon as possible :S

[SeanDKendle]

@citosid Just right-click and save the file to your local machine (desktop is easy to find...) then open your Add-Ons manager and click the little gear at the top right and choose "install from file":

[SeanDKendle]

Oh, I just saw you are on a Mac... translate everything I said (Windows) to Mac-language. I've never really used a Mac.

[citosid]

Thanks a lot.

I tried that before adding the issue. It didn't work either.

[janodvarko]

Sorry, not sure if I understand the answer, does it mean that it works for you now or not?

Manual installation didn't work either.

[janodvarko]

This is related to new Add-on Signing process (now mandatory) I'll fix it

[janodvarko]

I am talking to AMO people about how to properly solve this.

In the meantime, you can use Developer Edition [1] or Nightly [2] versions of Firefox that have a setting to disable signature checks.

Btw. here is the pref you need to set to false in order to disable the signature check

xpinstall.signatures.required

@janodvarko Thanks for your help. I´m using the latest version, so just changed that in about:config and now it worked. I noticed though, I need to leave it disabled, otherwise, Firefox disables Firebug...

I can live with that for the moment. Will wait on the fix.

Thanks a lot!

Thanks @janodvarko . Today I restarted firefox only to find out that after the restart it had disabled FB. I changed xpinstall.signatures.required to false and not it works again.

@janodvarko

about:config

xpinstall.signatures.required = false

Worked for me :)

Thanks for the tip!

[eikaramba]

FYI: in FF 42 this setting will not work anymore, then there is not way around a signed firebug plugin.

[janodvarko]

We'll start distributing the XPI through AMO beta channel soon (to get it signed).

@eikaramba The FAQ states:

What are my options if I want to install unsigned extensions in Firefox? The Developer Edition and Nightly versions of Firefox will have a setting to disable signature checks. There will also be special unbranded versions of Release and Beta that will have this setting, so that add-on developers can work on their add-ons without having to sign every build.

So in my case it will keep working... however I rather prefer to disable that option, out of security.

@janodvarko Thank you so much for your hard work... you have quite an extension.

Same problem here on Linux. Latest FF Dev Edition (on Ubuntu) blocks install of firebug.next.

[Nightmaster]

Any news about this ? Cause now, its no more possible to install firebug.next with Firefox 43 !

[fflorent]

• Type in the Firefox location bar: about:config
• Promise that you will be careful
• Search for "xpinstall.signatures.required"
• Set it to false
• Install firebug.next as you would do usually :)

[bzkdjc]

When using that method the Dark theme of my FF install immediately disappears! Does firebug.next require that Light theme? Why FF theme goes from Dark to Light after install?

[janodvarko]

When using that method the Dark theme of my FF install immediately disappears!

I don't see this problem. What exactly should I do to repro this on my machine?

[Nightmaster]

@fflorent Thanks, I though an update would remember the about:config modification, but this one is override it seams...

[bzkdjc]

@janodvarko I'll uninstall both FF and Firebug, then reinstall them, in order to get screenshots.

On Ubuntu 14.04.3 x64 FF Dev Edition 43.0a2.

Results:

Screenshot: Just installed FF Dev Edition linux64 43.0a2:

Screenshot: 3 minutes later after install of Firebug 3 alpha 13 using no xpi sig:

Do you see that FF theme was dark right after install, and that it turned light after Firebug install?

[Nightmaster]

This is not the Light Theme, but the Firebug Theme. You can see the difference, because you have the full firebug console, otherwise this is the Firefox console with the DOM tab added inside. You can see it if you click on the Firebug's cog (parameters) button.

And it is the best place to re-enable Dark theme !
