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?

Is it possible to restore firefox to a previous version to recover all my data? After update, all my firefox pages, tabs, bookmarks and history have vanished. Please help me recover or restore. Thank you!

Hi there, I'm trying to make a little old machine useful it is an HP mini (Laptop) with an Intel(R) Atom(TM) CPU N455 @ 1.66GHz and 2GB of RAM; it appears the firefox version is too old to install some extensions/add-on like uBlock... I don't want to throw it in the trash; any recommendation please?

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.

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.

Just found out my copy of foxy proxy standard, wappalyzer and one other, cookie manager were no longer working because this message, Installation aborted because the add-on appears to be corrupt. Updated to a newer version of Firefox in Kali Linux but have the same, message,Installation aborted because the add-on appears to be corrupt. Was just working a few days ago . I even did an update in Kali to see if that would solve the problem .Same message. Used CURL to update to current version of Firefox , supposedly, same, Installation aborted because the add-on appears to be corrupt. Do think I need to renew any certificates here because in WIndows 11 it updated automatically without problems. What do you think.THX

All I have is an older windows 7 dell laptop and firefox was working ok but then it said firefox must be updated by march 14 so i clicked on the update but it has been over 24 hours and the little circle is still going around with 0 results why

I am not an IT expert and find it difficult to understand the procedure in upgrading Firefox as directed by continuous log in directives I can not get rid of upgrade notice no matter what i try. So please stop sending this information to my computer. Kind Regards Stephen Boulton lstboulton@gmail.com
