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.

I try to set up Firefox Sync on Firefox on a VM on Fedora. I enter my e-mail and password. Then I get the message (after retrying): "Email resent. Add accounts@firefox.com to your contacts to ensure a smooth delivery." However, I do not get the email with the confirmation code.

My email address has this format j@xxxxx.org

I installed one of the ad blockers, I can't remember which one. It's given me so much trouble that I thought to disable or delete it. I deleted the little icon ( a stop sign) that shows up on the far right of one of the menu bars (don't know the name of that bar but here it's the second one down). But websites still complain that I have an ad blocker. I've gone to 'add-ons and themes' but I can't find it. BTW, what's the difference between an add-on, a plug-in and an extension? Which one of those are ad blockers? How can I see and then delete whichever blocker I still have? Without the icon I can't even disable it for individual sites.

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?

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.

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.

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!!!

Prior to getting some desktop PC upgrades that required a new install of Windows 11 and a new install of Firefox, I backed up my entire PC (yea!).

Now that I have re-installed Firefox, I see that I have none of my saved bookmarks and so I want to restore the Firefox profile - all of it or at least the bookmarks.

I have tried following the Firefox instructions for this, but am apparently not doing it right.

I can't seem to locate the bookmarks file, for starters, in my backed up files. I find the profile but I don't find anything like places.sqlite.

Can someone help me so that I am locating the right (and complete) files, copying them correctly, and then switching to the new/old profile correctly?

Thanks in advance.

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]

In case anyone's interested, under Debian 12, when I resume from hibernation, if I have Firefox running as well as Tbird, if I click on a link in an email, the existing instance of Firefox is ignored and a new instance is opened. The first instance is in fact frozen -- it looks as it should but trying to change tabs or open a new tab is inactive. Seems I have to kill the open instance of FF, then if I click on a link in an email, FF pops up as it should with a new tab for the link, but the existing tabs are all there and all functional. It feels like a bug -- Tbird seems not to know that FF is already running.

When reloading a page, or navigating to a new page, the default Stop icon momentarily appears over my own Reload icon, and the default Reload icon also appears over my Stop icon.

Please see attached image and animation.

Any idea if this is a minor bug?

Below is my code to split the Reload button into Reload & Stop buttons, then to add text to the navigation buttons, and finally to add icons to the navigation buttons.

This anomaly happens whether or not I split the Reload & Stop buttons. With just a single Reload button, I'm also seeing the default Reload icon appear over my own.

Thank you.

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.

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,

LS

I have a Plesk (apache) server that is behind HAProxy. When I connect securely to a web site through HAProxy using Firefox, I get long delays. If I use Safari or Chrome, the pages come right up without any delay.

If I connect to the Plesk server directly without HAProxy in the middle, there are no delays.

I do not know what would cause these delays that don't occur with other browsers.

I'm on a Mac: 115.0.2 (64-bit)

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.

Hopefully you can help. I know this may be a Microsoft issue or question but I'm having trouble in finding a reasonable way to contact them for help. My question is, my computer runs slow, and so I thought I would clean up my files by using the Microsoft disk clean up procedure. I did so. But, my specific question is what is a good number to have when the it says a given number of disk space can be cleaned up? For example, I believe when I first tried to clean the disk it said 5.1 GB of disk space could be cleaned. When I ran the disk clean process and it completed it then said 66 KB of disk space could be cleaned. So how much disk space did I gain or get cleaned up? And, if I can only clean up 66 KB of disk space is that indicative of not really needing to clean the disk any farther? Hopefully some one can help. While this may be a Microsoft issue, I believe the Firefox contributors have enough computer knowledge to help answer my question. At least that is my hope. Thank you.

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
