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.

After updating a W10 laptop from 115 to 116 of FF the user started having problems with getting to different websites (sites they worked on/with regularly). The problem is the cert DB. The doc I found says that it is cert8.db. Actually it is now cert9.DB.

What I had to do was go to task manager and kill a task that was holding the cert9.db file. Then I could rename it (cert9.old.db). Then restarted their laptop and FF came up and started fixing the cert file (as expected). This seems to have fixed their problem.

When i go to "about:memory" and do a measurement to see whats eating memory i find extensions that are nowhere to be found in the extension manager nor in the folders where the extension files are. they are: - Extension(id=wikipedia@search.mozilla.org, name="Wikipedia (en)", baseURL=moz-extension://8551 - Extension(id=webcompat@mozilla.org, name="Web Compatibility Interventions", baseURL=moz-extensi - Extension(id=screenshots@mozilla.org, name="Firefox Screenshots", baseURL=moz-extension://486 - Extension(id=pictureinpicture@mozilla.org, name="Picture-In-Picture", baseURL=moz-extension:// - Extension(id=google@search.mozilla.org, name="Google", baseURL=moz-extension://13f3307a-648b- - Extension(id=formautofill@mozilla.org, name="Form Autofill", baseURL=moz-extension://dfdf20df- - Extension(id=ddg@search.mozilla.org, name="DuckDuckGo", baseURL=moz-extension://c8eb7a13-e1ab - Extension(id=bing@search.mozilla.org, name="Bing", baseURL=moz-extension://424719d2-8ccf-4c8e- - Extension(id=addons-search-detection@mozilla.com, name="Add-ons Search Detection", baseURL=moz- (the names are cut thats how it shows and at the end there is a "..." i cant select) I tried looking everywhere and i cant find where are this extensions to delete them. i use the google website to do searches so dont need an extension, i dont use duckduckgo at all, i dont use bing at all, i dont use the screenshot feature, i dont use the picture in picture thing and also i use the wbesite if i want to go to wikipedia. I would like to know how to erase them entirely since i dont use them and they are eating memory.

Is this 115.32 still in effect for my macOS 10.13 ? Or is it xld as it would be in Feb 2026?

Did or does Firefox 115.32 afford my apple macOS 10.13 enough security until I purchase a new computed.. How much more time do I have.

I realize Facebook doesn't have a spell check feature,but is there a way my browser, Firefox, which I already have spell check enabled can somehow spell check Facebook when I chat? Can someone help? Thank you.

For the past few months every restart of Firefox disables LastPass. I did NOT have this problem previously. The version of LastPass is current (no updates found). I can go to Add-ons and the toggle is set to "on" but the icon in the menu bar is black. If I click the toggle off, then back on, LastPass comes on just fine. Why is Firefox disabling something that Add-ons says is loaded? VERY strange. Does NOT happen in Chrome. Thanks for any assistance. PITB!!!

I have not been able to connect to www.paperbackswap.com for 2 days using Firefox. I get this message - The page isn’t redirecting properly-An error occurred during a connection to www.paperbackswap.com. This problem can sometimes be caused by disabling or refusing to accept cookies. This is a persistent problem happening every few days. I have sent messages before to PBS and Firefox with no response. I have cleared cookies and added PBS to Firefox as a site to always accept cookies. I can access the site using Chrome but I would prefer Firefox. Is there anything that can be done?

Here's the error page I get from O'reilley Auto Parts when searching. (I don't get this error when on O'relley com, but ONLY when searching for a part and ONLY with Firefox on my desktop. This started just a few months ago. All ad blocks and U Block Origin are disabled):

Contrast disappears when I klick 'Login' eg. on 'https://www.elektor.de/'; other browsers are ok. AdGuard on or off makes no difference. Kind Regards [removed email from public]

Dear Ty: I appreciate your efforts to help me, unfortunately, it did not work. FireFox is still at 115.30.0. Any other thoughts?

I thought there might be some software I could download to spoof the Chase system into thinking Firefox was a later version,

Thanks and regards,

Rebuilt my computer, restored Bookmarks from 'bookmarks-2025-08-30.html' but the original 'Other bookmarks' (just below 'Bookmarks toolbar') is now empty and has been moved to the bottom of all my other bookmarks in a new 'Other Bookmarks' folder. How do I get the contents back in the 'Other bookmarks' (just below 'Bookmarks toolbar'). P.S. I have a backed up 'bookmarks-2025-08-30.json' as well as a ' bookmarks-2025-08-30.html' available, if that would help. Regards and Best, NP_145

Hello, I am still running an old WIn 7 media center because I have applications I need that are no longer supported elsewhere. Firefox ESR has been working just fine up until the most recent update - which repeatedly fails to install each time I start Firefox. Is there a location where this update resides? If so may I know this location and procedure to eliminate this errant update? Thanks!

Hi

Up to a few days ago I was able to see "View all memories" from One Drive in Firefox. Not anymore.

I am subscribed to One Drive. Every few days I get an email from One Drive with the past memories from the day of the email. I will open the emails and click on "View all memories" then it would take me to the One Drive and I would be able to see those pictures individually. For a few days now I have not been able to do this on Firefox anymore. The website goes to gray like it is trying to download the pictures but it gets stuck there.

This is happening both on my desktop with Windows 7 and my laptop with Window 11. Everything works in the Microsoft Edge browser. I can see all the images individually from that day.

I have communicated this problem to Microsoft One Drive and it seems to be a browser problem. Is there any way that this problem can be solved in the Firefox browser?

I would appreciate your help, Amy

Why has Video Download Helper v9 by Michel Guteriezze been replaced by Video Download Helper by vdh? The original versions were perfect. The VDH version 10 vdh is straight junk!

Just over a week ago, I found that a particular page transition always crashed by browser tab (i.e. a reproducible crash). This occurred on the Quora.com website when visiting the 'Questions' tab for any Quora Space. I am not aware of anything special associated with this operation, and it works OK in Chrome. There may be other cases -- outside of that particular website -- but that is the one most affecting me at the moment.

There are no associated Windows events logged. I checked about:crashes and the Crash Report folder but i cannot find any readable details.

If I refresh the page then the transition occurs without problem.

I would like to find the cause myself because I am on an Windows 7 64-bit ESR version, although I do not believe this is an ESR issue as it was working fine a couple of weeks ago. it is just that I cannot find any logged information on the cause.
