Firefox Community Forum

Hi there, im using a grandfathered firefox due to my old OS (10.10.5) Tonight ( 3/15/25 ) all my extensions (duckduckgo, adblocker plus, badger, etc ) were disabled. how can i enable them again? thank you for your time

I'm finding that firefoxcp isolated web content uses a LOT of memory on my Mac Mini. What can I do about this besides not using Firefox. I like the browser and have been using it since its introduction

1, provide phone support....which i am willing to pay for.

2. fix it -- remove the problem via an update

3. A new computer....and I still get this "Application error: a client-side exception has occurred (see the browser console for more information)." WHY ? Of course, GREAT that Mozilla never has real people to staff tech support.

send me an email

Kindly, I will request to regain my account back I just create for searching new job but, without knowing my acco unt has been restricted. I kindly apply my account has restricted incorrectly and I will apply to recover my account. With best regard! Fentahun Ayalew Liyew

I normally use Firefox Developer Edition, version 127 because any later version always freezes my whole computer (probably because I'm using a 15-year old PC). Recently all my extensions became disabled. I'm now also unable to install any extension because it says "Installation aborted because the add-on appears to be corrupt". I found some instructions on Mozilla website about deleting compatibility.ini and extensions folder, but it didn't solve the issue. Now I'm stuck and confused as I suspect some of the extension files that should be in my Profile folder may not be there.

The simplest solution in this case would be to use the "Refresh Firefox" option which resets everything to default settings, but every time I do it my computer freezes until rebooted. Uninstalling and reinstalling manually is also not the way to go, because it retains all the settings.

I've tried installing the standard Firefox browser (v. 119) alongside the Developer Edition but the same issue is there as well.

I'm looking for an alternative way to get a clean Firefox install, so I can fix my extensions.

Additional info: - Your system specs? Windows 10 64-bit, 4 GB RAM, Pentium Dual-core, no GPU - Hardware acceleration? Disabled. - Using any mods? Yes, two. Geckium for Firefox, which always works fine. The recent issue started when I played around with Revert8Plus, but it initially worked without issues.

When I display a statement from Tesco Bank it opens a new tab and says that I can download or print it from there but I can find no Download tab nor anywhere in the customisation options to add one.

i was browsing youtube and suddenly got an ad, which is how i noticed my add-ons were gone. all of them, not just the ad blocker. and they had still been there like a couple of minutes ago. when i go to download any extension, i've tried a lot of them, it just says "installation aborted because the add-on appears to be corrupt" but it doesn't say what i can do about that. please help!

Hi,

I have a very old version of Firefox (51.0.1 64-bit) on Windows 7 Pro. I know it's well out-of-date. It's not my "main" browser, but there are some things I use it for because there are (were) some handy old extension on it. For example there's an extension that simply copies any text I highlight, without my having to press CTRL-C. I find the "scrapbook" invaluable for saving info offline.

Yesterday everything was fine. Today ALL the extensions have been disable because "[extension] could not be verified for use in firefox and has been disabled". There is no option to enable them again.

I have backups of the extensions (xpi files), but firefox is telling me that they appear to be corrupted.

Is there any way to either enable the disabled extensions, or force firefox to reinstall then from my backups? I have toggled "xpinstall.signatures.required" to "false".

Thanks for any help.

I update software on a regular schedule, and would prefer to not have Firefox (136.0) nag every few minutes that I'm not on the latest and greatest. 120.0.1 only nags a little. How can I turn the nagging totally off?

I added the following to `~/firefox/distribution/policies.json`, but it didn't help.

``` {

   "policies": {
       "DisableAppUpdate": true,

"DisableSystemAddonUpdate": true, "DisableTelemetry": true, "ManualAppUpdateOnly": true, "AppAutoUpdate": false,

   }   

} ```
