Firefox supportforum

I'm on firefox 90.0.1 on Mac OSX Big Sur 11.2.3. When I try to delete a site certificate that I have (that is about to expire), it appears deleted, but when I open the certificates page again it reappears. When I restart Firefox after deletion it reappears. When I delete cert9.db from my default profile after closing firefox, and then reopen, it still reappears. When I uninstall Firefox, delete the default profile folder from App Data and the Mozilla and Firefox folders from my caches, it still reappears (I also deleted the update folder).

I am doing sync between this mac, my phone, and another computer, but I ONLY have bookmarks, Add-ons, and history. Might the sync be also syncing my certificates?

Help/tips would be appreciated.

I store passwords on firefox account and use sync to share passwords across devices. I did not delete any passwords on any device. recently, I saw that only google account passwords are missing and rest passwords are intact in saved passwords. my google passwords have been stored since a long time. all my old and recent stored passwords are shown in firefox but only my google account passwords are gone on all the devices. I tried login-backup.json but there is no change in passwords shown. need help.

Upon the subject action, Windows 10 takes a system/memory dump, sends it to Microsoft, and automatically restarts. Firefox appears to be initializing for about 3 seconds (after clicking its shortcut) and then the crash occurs. The display of the initial Firefox landing page is not obtained.

The blue screen of death (BSOD) has this message: KMODE EXCEPTION NOT HANDLED

Also, the networking software (NETGEAR) is rendered inoperable and must be re-installed upon Windows restart. Otherwise, my system is stable. Maintenance is regularly applied as it becomes available.

Firefox was a delight to use. But now not so much, as it's unavailable as described above.

If anyone has a fix, or a suggestion for obtaining one, it would be gratefully appreciated. Thanks!

Walmart website no longer works properly with latest Firefox 96.0.2 64-bit. It works properly with Chrome and other browsers. You can log onto the site and search for products but when you try to add a product to the cart nothing happens. You also can't actually go to the cart. Last time I used Walmart was a few weeks ago and everything worked fine!

I found some infos but I do not trust myself just deleting the files in question since they ared all over my system. The following I found per malwarebytes which found the pups every day up to now:

PUP.Optional.DefaultSearch is Malwarebytes’ detection name for a family of browser hijackers targeting Chrome, Firefox and Internet Explorer. Symptoms The browsers’ default search engine was changed to one that belonged to the threat-actors. I am german so probably I need your patience in helping me to clean my system resp. Mozilla.

Looking forward Ingrid

I have an older PC but it was working fine with Netflix and Prime Video until this latest update (v89.0). It seems that when I try to go to Netflix or Amazon Prime Video the browser crashes almost instantly, and usually shuts my whole computer off. It doesn't go to a blue screen, the computer just decides it's time to reboot. Now again, I'm using an older machine (and I can't afford a new one), but this was never a problem until this latest version of Firefox.

I am also not a fan of the aesthetics in this version and I'm wondering if I can revert back to an older version where the crashing was less frequent. Any help would be appreciated.

Hello since i've upgraded to firefox91, i've got a tab crash each time i go to ebay.fr. The message is : "Gah. Your tab just crashed."

I've submitted the bug report : ee05d71c-a653-4c91-9094-42ea10210821 I've been able to produce the problem only with ebay.fr and ebay.com. The problem does also occur in troubleshooting mode. clearing the cache does not help.

System is linux fedora up to date

Suggestions and help are welcome to solve the problem...

This the second time I am entering this problem -- the first time Firefox refused to let me return to this site.

First, I am running Firefox on Ubuntu, but Ubuntu is not relevant because the same issue occurs in Windows.

Whenever I access a file, for example, one at https://species.wikimedia.org/wiki/Chioneosoma, its color (which is programmable) changes from a light bluish green to a deeper violet. Where is this color-difference stored? I have thousands of WikiSpecies files I have accessed, and they all show the violet "accessed" color if I ever have opened the file to read its contents. The problem is that when Ubuntu has to be reinstalled, I can add references to all my files, but the color-changes seem to be lost. This is a serious issue, because I currently have over 50,000 files referenced (and saved in my directory file:///home/jwill/Documents/WikiSpecies/Animalia_Plantae_8) and am still adding to them!

I think the storage location must be somewhere in one or more of the following files ('_' replaced '/'):

   _home_jwill_.mozilla
   _home_jwill_.cache_mozilla_firefox 
   _home_jwill_.cache_MM_firefox
   _usr_lib_firefox

Can you please tell me where the list of accessed files is stored? Whenever I enter a referenced directory, to access it, the color changes; so, Firefox must be able to store a reference to each new referenced directory name.

Firefox will start once (maybe) and then it makes no difference where I click from (tray, programs, desktop shortcut) Firefox refuses to boot up. I've tried re-installing multiple times. If I reboot, it will start. Also sometimes I will get a New tab but the page/URL never comes up. Firefox just hangs. I'm running Windows 11.

I really try to find an answer online but looks like nobody find this to be an issue. Of course i have my password vault locked with a master password. But remembered logins on websites like Google and Facebook are secured by cookie login. Which not require my master password. So when someone use my computer unsolicited, this person gets instant access to my GMail/Facebook.

So how to protect per-logged in pages without resetting cookie data? Because i liked to benefit from instant access to al those website so i don't have to login everywhere any moment i start Firefox.

firefox not opening since 2022-01 Cumulative Update for Windows 11 for x64-based Systems (KB5008353). I reloaded Firefox. Google Chrome and Microsoft edge work OK. Task manager shows running but stats never change 0% CPU/0.2MB Memory

Firefox was one of the system updates I installed today on my Linux Mint 19.3. I updated it and discovered all history and bookmarks are gone. I have no Old Firefox Data folder. I tried about:profiles but the only other profile is the default Linux one. I tried to Restore from Import and Backup in Manage Bookmarks for several different dates, but only get "Unable to process the backup file" error. I also tried to choose several .json files from the STG-backups-FF-8x folders in Linux Downloads directory, but it doesn't seem to do anything. I've tried using Timeshift to restore from previous system dates, but it would only create Firefox folders with the same outcomes as above. I don't really care about history, but I have a lot of bookmarks that would be very difficult to recreate.

Thanks, in advance, for any help getting my bookmarks back!

Hi there, I'm having trouble opening firefox that suddenly didn't open after I've used it as usual. When I've closed it, I've put the macbook on sleep mode and then reopen it after 10 minutes and tried to open firefox as always. It didn't. I'm trying to figure it out and I've followed all the possible paths on Mozzilla's support and others blogs, but none of them worked out. I've tried also to uninstall and re install firefox from scratch, but nothing happens: I still get the message. At this point I don't care if I need a fresh start, I have a bookmark's backups so, how can I really uninstall Firefox and install it from the beginning? Is there a hidden folder I'm missing? Thank you in advance

A short while ago, Firefox was automatically updated to 99.0.1 on my iMac running Monterey 12.3.1. Suddenly, for no apparent reason, the search engine is stuck on Amazon with no other search engine options available. I normally use Google.

Even if I go into the Firefox settings to the "Search" panel, it is showing ONLY Amazon as the available option in the pull-down menu under "Default Search Engine". In the "Search Bar" section, I have it set to "Add search bar in tool bar". But even if I set it to "Use the address bar for search and navigation", and then switch it back to "Add search bar in tool bar", Amazon still remains the only available search engine.

As a last step, I installed the "Google Search" add-on by 3Indian to see if I could get back my Google search engine, but Google still doesn't show up as an option anywhere, and I am still stuck with just Amazon.

Is this a bug in the latest Firefox build? Did the developers forget to enable something when they did this build perhaps?

Hello! I am in a work environment and I am trying to determine if there is something in our security systems that is preventing Firefox from running properly. Once Firefox is installed, it works the rest of the day with no issue but almost daily the morning after, it will start to open then instantly crash. When I check the crash logs, it shows in most of them: Modules - Filename: umppc14210.dll Version: 6.28.14210.0 Debug Identifier: B9143DE260194C88AB48EFD6782C9EAF1 Debug File Name: umppc.pdb Signed By: Microsoft Windows Hardware Compatibility Publisher

When using the dark theme from Firefox, Google searching seems to break completely as well as some pages will not load which may be related to this.

I have already tried uninstalling Firefox, deleting all of the folders, then reinstalling with a freshly downloaded installer (Even tried the beta one) with same results. It seems potentially MAYBE related to how long ago I closed Firefox before I shut down (Like Firefox is trying to save something to a secure location and times out, then it will work but if it hasn't timed out, then it crashes... or this is my guess)

The Signature seems to change randomly for the crash between crashes.

I really am tired of constantly reinstalling Firefox but I do not want to use Chrome or Edge unless websites require it.

I've started having a strange issue with both Firefox for Windows and Android. On some news websites, and sports websites, I can no longer open articles just by clicking on them, but right-clicking works. If this sounds strange - it is!

The issue is exactly as it sounds like. I can hower the mouse over the title of an article and Firefox will recognize that it's a link, showing me the path at the very bottom left of the browser. But when I click it, it simply won't do anything. My mouse works fine before you ask. It's only when I right-click the same article and choose "open in new tab" that the article opens. This is happening on some major sites as well, like the BBC.

At first I thought this was Windows-specific, but I have also had the same issues with my Firefox for Android. And again, long-pressing on the article and selecting open in new tab will open the link, but not normal tapping.

I have restared Firefox in Troubleshooting mode to disable any addons but the problems persist.

Anyone else having the same issue or is there a known solution?

Hi, I'm running Firefox on Ubuntu 20.04.2 LTS Gnome Version 336.38. For at least one month now Firefox has stopped working. When I start Firefox normaly (or in the tor-browser bundle) the Firefox-Window opens but no page is loaded. No matter what page I navigate to, nothing happens. I can't even open the firefox settings. I updadet from the normal version to 89.0 but still nothing working. Anyone got any ideas?

Hello. Im new to the Mozilla Support community

I am running a Japanese Windows XP SP3 on VMWare Workstation 16, i have downloaded a old version of firefox, due to newer versions not working on xp

And heres the issue: Firefox keeps opening tabs randomly which are related to pornographic websites like xxnx, pornhub, evilangel n' etc..

Heres things ive tried, but didnt work: -Install tdsskiller & scan -Scan with Avast Antivirus -Uninstalling Firefox and delete registry entries -Getting IE8 or G**gle Chr*me for Windows XP SP3

Any way to resolve this problem? i can't watch these things!

I'm running 96.0.3 on a fully patched Win 10 Pro system - both O/S and programs. When Firefox is running I'm getting these pop-up error messages randomly with changing content. They stay on screen for some seconds and then go away. Message states it's from (via) 5.back2yard.biz. I put that in my hosts file and I'm still getting them. My network is a cable modem hooked to Xfinity and then cable connected to another fully newer patched router. All addresses are 10. range. I ran both a Malwarebytes scan and a Windows Security scan - both are clean.

I'm unable to upload a small image after a hour so I'll give up on that right now.
