I am on 54.0.1, so before you tell me to download the current version, this is it. Yet, every add on and extension I try to download tells me I can't install it, because my browser is in beta. How do I get out of this beta system? I hate it.

All you have to do is get the full installer and it will do the job for you.

Download Firefox For All languages And Systems {web link}

This is exactly what I have. It has changed noting. I'm still in beta, and still unable to install necessary add-ons I need for my job.

I agree, that error message doesn't really make sense. Your Troubleshooting Information doesn't seem to explain it.

Where are you trying to install from. Can you give an example page?

If this problem is occurring from within Firefox's Add-ons page when you use "Get Add-ons", try installing directly from the Add-ons site instead, in case the embedded page isn't working correctly.

The one I need specifically is Xkit, which isn't on the addon store, because of reasons I don't understand. (I also can't download it directly, because it's unsigned; which is also irritating, because I've used this addon before, and now I can't.)

This is what the page looks like for me.

Unfortunately,the last XKit update was for Firefox 35. If you create an override preference to tell the site you have Firefox 35, then you get the real install page -- but it's still version 7.4.5, so it doesn't really resolve the issue you have installing the extension.

Also, the lack of updates suggests it is not really well supported for the many later changes, and may not work as intended.

I wonder whether anyone has taken this code and carried it forward? An internal file in the extension indicates that it involves some compiled Greasemonkey userscripts, and in fact the installation page warns you to "Disable or uninstall Greasemonkey, Stylish and other Tumblr extensions before installing XKit." So possibly these tweaks are available in another form. I have no idea where...

I noticed the Chrome extension store has something called New Xkit (, also from 2015. If you have Chrome and can use it for this work you need to do, you could check whether that does what you need. If not, hopefully you can find another solution because it's simply not safe to run Firefox 35 on the web anymore.

Can you attach a screenshot?

You can check for problems with preferences.

Delete possible user.js and numbered prefs-##.js files and rename/remove the prefs.js file to reset all prefs to the default value including prefs set via user.js and prefs that are no longer supported in current Firefox releases.
