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.

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 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!

The add-on, Enhancer for YouTube, appears to be the cause of a very annoying bit of behavior. My YouTube tabs seem to be all numbered. I hate this. Why make a bookmark, I have to manually remove this number before I can auto sort my bookmarks directory alphabetically.

Worse, there is no part of the description that identifies this bad behavior as being involved with Enhancer for YouTube. I had to go to AI for help figuring out how to get rid of this exceedingly annoying behavior that showed up whenever I used tabs with YouTube videos. I can't imagine anything that this add-on could be adding to my experience that is more convenient than this particular behavior is annoying.

Changes to the appearance of tabs should not be performed invisibly and without settings that I can disable. Because of this, I can only get rid of his horrible behavior by disabling the entire add in. Mozilla put a stamp of approval on this particular add-in. So the dirt is on your face, too.

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

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!

The extension ConfirmBeforeDelete is extremely useful. It has saved me not only from accidentally deleting messages, but also from dragging and moving folders when I didn't intend to.

I recently had to manually recover from deleting 20 messages in a search window after I had accidentally hit the delete key (while I thought my cursor was up in one of my search fields).

Really, that functionality should be a built-in feature in Thunderbird.

The latest version of ConfirmBeforeDelete is 1.9.3, released Nov. 20, 2023. Compatible with Thunderbird 115.*

What did that extension need to be compatible with Thunderbird 128+? In other words, what change(s) in Thunderbird broke it? Would the fix be something easy or will it require more significant changes?

I tried to contact the author last October (even offered to gather some donations), but have not heard back.

It looks like there was already at least one person interested in helping. Thread on github:

HI, After upgrade to Seqouia 15.6.1 an extension for developing Oracle APEX applications breaks Firefox. It is the only extension I have installed. Console information is not really that helpful. Maybe you can make some head and tails about it.

Hi there,

Is there a way to get checkboxes to select messages or at least a plan to get it in a future release? I saw that there has been an add-on in the past, but not maintained for some years and therefore not possible to use in newer versions. Yes, I know that you can select messages with ctrl and mouse click, but there are others in my family who are not familiar with it and reluctant to get used to it. (have used gmail for too long).

Greetings Grauer

One of if not my most favorite addon "context search" has recently been flagged as violating mozillas tos. I'm talking about this one: https://addons.mozilla.org/de/firefox/addon/contextsearch

I am unable to find further explanation or the exact reason for this decision, but I am able to activate it again at my own risk. Seeing as I don't know what the problem is, I am hesitant to do so. Could someone explain what the issue is and if it's safe to continue using that addon? Am I or is my personal information at risk, since I have been using the addon regularly?

Hi! I have been using Shrunked Image Resizer's module for a long time (reduces the size of attachments before sending). It's no longer compatible with the new version of Thunderbird (140.1.0). I don't find any alternative module to replace it. What's the solution please?

Hello,

I'm having a problem moving messages from one folder to another. There's one message which will not move no matter what I do. I'd like to turn off QuickFolders so that I can determine whether it causes the problem. How do I turn QuickFolders off, and then when I'm done with my experiment, turn it back on again?

I follow the instructions to pin an extension, but when I click on the jigsaw icon, I'm taken to the add-on manager page with the ability to review recommendations and manage the extensions and themes. There is no option to pin any extension. I saw this issue on an expired post to Mozilla but the answer was incorrect.

Any ideas? I can't access my password manager extension even though it's there....

I just discovered a bunch of installed extensions in the list I don't recognize, including several I definitely would not be interested in.

Is this the way Firefox android works?

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 !

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?
