Last week, all 11 of my Firefox extensions, which I've been using for years, were suddenly disabled. For each I got the same message: "[Extension name] could not be verified for use in Firefox and has been disabled." Following Firefox's instructions, in about:config I switched "extensions.langpacks.signatures.required" to FALSE, restarted my computer, but nothing changed. I tried reinstalling the extension Adblock Plus from Firefox's own list of add-ons, got the message "Installation aborted because the add-on appears to be corrupt." Any idea what's going on and what I can do?? Thank you.

iMac OS 10.11.6 El Capitan; Firefox version 78.15.0esr (64-bit)

On my Macbook Pro — OS 12.7.6 Monterey, Firefox version 136.0.2 (64-bit) — the same extensions work just fine.

apparently, programmers don't understand how aggravating not having backward compatibility is to the rest of us, so please bear with my extreme aggravation here. IF IT AIN'T BROKE, QUIT FIXING IT.

 firefox disabled my addons, thus forcing me to upgrade, and now I am angry. Tried downloading the new version several times. My os is as updated as it can get. Using the APT link from this site, it just shows garbage. Using the download for linux 64 bit link, it makes me jump through hoops and looks like it is working, but it looks different and none of my bookmarks transferred over. Closing it down and reopening it, I see the old version, thus making it look like I am possibly running both versions separately. Once the *all new singing and dancing special that is supposedly so much better than the old that some ignoramus decided I MUST use it instead of the old and functional one* is closed out, I see no way to reopen it. And neither version will enable or allow me to download singlefile. That is the only program I need from firefox at this time.
 Will somebody please show me, step by step, as if I am 5 years old, a back door that will enable my addons, before I go nuts and start beating programmers to death with reams of algorithms?

The other day I discovered all my extensions have been disabled. I have an old Mac and am not able to upgrade to a newer version of Firefox. Is Mozilla going to offer a solution for people like me who find their preferred browser to now be frustrating and inefficient? I would love to restore my add-ons. Thank you.

I have Dark Reader installed and it works perfectly almost anywhere, but ironically, Firefox' support forum itself comes out all white regardless if it's on or off?

I'm on OpenSuse Leap 15.6 with KDE Plasma 5.27.11.

Hello, i am wondering about the blocking of extensions on "Quarantined Domains".

Is there a list of them available to explore? Who maintains this list? Can some fishy website admin add his domain to it to block some 3rd party security addons? How can i whitelist a fishy extension on only 1 blocked site without losing the protection?

The faq articles are not really helpful for this.

This question is about a specific Firefox add on. I have not used extensions or add ons previously and am concerned about the safety of the one I want to upload: Claude Conversation Capture.

The page says it will require permission to Download files and read and modify the browser’s download history (which is fine) and Access your data for all websites (which scares the heck out of me.)

How can I safeguard my privacy and data to prevent a breach and maintain proper security if I download this add on?

Can anyone help with this please? The add on would be extremely useful but not at the expense of my security and privacy.

FWIW I am #notageek and very tech challenged, so please explain anything I need to know in ordinary language I can understand (will be greatly appreciated.)

Thank you!

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!

I can't figure this out. I've been having this issue ever since I deleted my KMspico files after I did a scan using Malware Bytes (it was labelled as dangerous files or whatever so I let the app delete it).

After the restart, I can't use nor reinstall the Discord app along with being unable to download any Extensions, Themes, or Plugins for both Firefox and LibreWolf. It's frustrating as I had to go back to previous browsers, which I didn't want to do. Any help in fixing this is highly appreciated as I really want this fixed.

--- File location is C:\Program Files (x86)\LibreWolf [Same for Firefox]

--- Must I reinstall Windows in order to fix this issue or are there other ways that don't involve reinstalling Windows?

I’m using Firefox version 134.0.2 in MacOS 15.2 with 1Password version 8.10.56 for Mac. The 1Password extension is enabled and the app is open and unlocked but each time I open a site requiring login and password I get a pop-up telling me to, “Press the 1Password icon in your browser’s toolbar to unlock.” This requires me to unlock 1Password again to enter the site’s login/password combination. Not sure if this is a Firefox or 1Password issue but it’s annoying. Any thoughts on a resolution? Thanks

Hi!

Since the root certificate expiration that happened two weeks ago, I have tried to find solutions to re-enable my add-ons on my FF 88.0 unsuccessfully.

I cannot update to later versions, so I would like to find a way to keep using Firefox, and thus to re-enable my add-ons as well as the screenshot feature that is currently bugged.

Would anybody have a solution to provide?

Is there anyway to force actual mozilla pages to be displayed in a dark mode instead of the blinding white background that hurts my eyes to view ? Thanks, David

Windows 11 FireFox 135.0 (64 bit) How to pin an existing extension to the toolbar, please ? E.g. Video DownloadHelper. My browser is up to date.

In "Extensions", I select "Video DownloadHelper" then click on the gear icon. I cannot find "Pin to taskbar" there or any where else. See the image for the menu I do get.

Thanks !

Last night, firefox just disabled all my addons and all attempts to reinstall any failed with a red warning that everysingle one I had or new to add failed. I tried a few suggestions I found online like refreshing, clearing cash, restarting, but nothing worked.

I have a vwersion 88 (and some change) running on a windows 7 computer.

Any wisdom is highly appreciated.

If I won't be able to fix this, I'll just move on to a different browser after using it everywhere for so many years and it will be sad

Hello 1) How can I stop Google pop-ups? Each time I open a homepage that requires a log-in, a Google pop-up is disturbing and presses me to log-in via Google. This is harassment. I do not want to be harassed. 2) Firefox support: Each time I would like to get an answer, that is what I want, when I ask for support, I have do a lot of work until I get the bottom to contact you. Time is money, for me too. Where is the direct button to ask? 3) When I got an answer from you, is there a way I can store my questions and your answers? Asking and getting an answer by E-mail would be a good solution, but as I learned e-mail is not allowed to contact you. Kind regards, Ernst Kupfer.

The Avast Password Manager was deleted from task bar about 5 days ago or so-- 12/11/24. Why would Firefox do that and inconvenience its customers? It needs to be restored immediately and nowhere to find help on this matter. Avast is aware of the problem and so is Firefox but we, the customers, have no solution that is available. This encourages us to use Chrome instead. Is there a solution? Please advise.
