I have the last Firefox version and am trying to add extensions (e.g. video download helper). When I click on Add to Firefox, it works at loading the extension, but without any success. The blue dot in the gray square dances and dances and dances.... Thanks !!

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 I know it's well out-of-date.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.

Hello! Yesterday (03/16/2025) I received a message that the ChatZilla add-on to Firefox will be disabled on the next restart of FireFox. The message indicates that the extension could not be "verified".

I am using a VERY old computer for ChatZilla only: Windows XP Firefox 48.0.2 ChatZilla 0.9.92

I don't care about the age and inability to update any of the software, but I need to continue to use ChatZilla on this platform.

I have used ChatZilla on this machine for a very long time and do need to continue. Is there any way that I can make this work without having ChatZilla automatically disabled at the next restart of Firefox?

hi I would like ask if is any way manually to update Root Certificate for my old firefox 88 .My extension ublock stop working today .I try to this but not works in my firefox .

about:config xpinstall.signatures.required to false extensions.langpacks.signatures.required to false

I do not want to update my firefox .There is any way to do somthing to works Add-Ons.

All of my addons are disabled and won't re-enable!

They all say "addon name" could not be verified for use in Nightly and has been disabled. See attachment clipboard00.jpg

If I try to install an addon from the recommended extensions settings (for example "return youtube dislike ") I get a message bubble stating "The Addon downloaded from this site could not be installed because it appears to be corrupt. {OK!}" See attachment clipboard01.jpg

The message above about addons appearing to be corrupt happens if I go to any of my current addon pages and try to redownload them.

very frustrated, and pissed at how programmers always screw things up that are working just fine by upgrading crap. Now, I have suddenly had all of my addons quit working, was forced to update my firefox. Nothing changed, and it still shows that I am using version 105, instead of the all-new, better and fancier, singing and dancing crap that is being forced upon me.

I have been using Linkman for over 15 years and have a very large collection of bookmarks. Is there anyway to enable it? I'd hate abandon Firebox as I do need this extension please help.

Thanks

Sites tell me they won't show the page unless I disable AdBlock. I had it many years ago, but uninstalled it years ago. It does not show up in my extensions list. So, what do I do? Thanks, Bob K

Dear Sir,

Firefox is not working with Rabby Wallet and Metamask extensions.

It does no pop-up the window to see the transaction and sign it. Firefox 134.0.1 (64-bit). Windows 10 Home.

On Metamask at least I can click on the pinned extension and see the window. However it´s not the expected behavior, because it should open the pop-up automatically. With Rabby wallet it is impossible to proceed, even clicking on the extension icon.

Please fix it.

Hi,

I am the developer of the Dictionary Anywhere extension which is a Firefox recommended extension. Recently my extension stopped performing up to its expectations due to backend changes in public API that it uses to find meaning of the words.

However, I am unable to modify the code of extension to fix the issue as I am not able to login to my account due to it being behind MFA, and I have lost access to the phone which contains those MFA codes.

Can something be done here, to allow me to update the extension to rectify the issue that 50k users who use this extension regularly are facing? For example, can the extension be transferred to another account through which it can be updated, lots of users are suffering as the extension is not working. I have access to the source code of the extension .

Thanks and Regards

My gyazo extension stopped working .. i can not access my gyazo acc with firefox . i been using gyazo with firefox for years.. I was able to log in using chrome. But i like firefox. i have contacted gyazo support and ran threw all the listed trouble shooting steps. This just started in the past few days. Idk if there was a update or windows update or what . i tried everything . Anything you can add would be great.

This is the page i get when i try to log in. "Checking your browser before accessing gyazo.com ... Click here if you are not automatically redirected after 5 seconds." then nothing happens.

A non-profit I support suggested the "Give Freely" app. The extensions search in Firefox did not find the app. Is it known and trusted by Mozilla? It's privacy policy suggests it functions like most other apps: it collects all the data it can, and allows the third parties that support their functions to collect all the data they can. The third parties can do whatever they like with my data.

Thank you,

The other day, several of my extensions were automatically uninstalled from a bunch of my devices. After going through and reinstalling most of them, the reinstalled extensions don't seem to be propagating to other devices via sync. Newly installed extensions that I didn't have installed before seem to propagate fine. Is there some way I can fix the extension data on my account so that they start syncing properly again?

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!

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
