On windows 10, I had my history setup perfectly. I had it where it saved all of my stuff all the time and I could go back and check anything on any day. Then I changed to windows 11 and now my history is a mess and I can't figuar out how to fix the problem. I am not good with computer, so make your answer SIMPLE AS POSSIABLE, please!!! Thank you.

Hello!

I am getting consistent issues with Firefox where the tabs seemingly just crash with no rhyme or reason to them. Could be within a few seconds, could be after a few minutes. Doesn't seem to be one website causing it either as I was worried it was Twitch but I get issues browsing other places too. Any help would be appreciated!

Here are the last 5 crash reports:

Tonight I received a notice that a new version of Firefox was available and asking if I wanted to download it. It showed me the new Kit mascot so I decided to let it install. It seemed to install normally but when it tried to open what I guess is a welcome/new features page, it crashes, and just showed a prompt to try again. This continued in an endless loop and I had to shut it down. Unfortunately I no longer had a functioning version available that I could find so I downoaded the ESR version to be safe (ver 140.5.0esr) which I am now using. Somehow I was able to recover bookmarks and hopefully other saved info. Can anyone advise what has happened? I have used Firefox for many years and never had this sort of problem before. Running Windows 11 on a new Dell i7 PC.

Hi! So I just installed firefox and I got onto annoying issue. I like using shortcuts on my homepage, but I started to get some shortcuts added automatically and they bother me a lot. I tried removing them or deleting from history, but as soon as I click the button, one shortcuts gets removed and immediately gets swityched with another one automatically. So I'm stuck in the infinite loop of removing shortcuts and my manually added ones just get lost in all this mess.

It looks like with this new version of Firefox I have to load my saved password file every time I start the browser, and even after doing the reload some of the passwords don't work forcing me to change them, and I would have to do another password save, but if I forget to do it and close the browser all the passwords are delete. I did not have this problem prior to this new install.

Also I prefer to use Firefox as a browser I feel it is way better than Edge and Chrome even though it doesn't work one a two websites I need to use. one only works on chrome the other only works on edge.

Let me know if you need other information.

Mon. 11/10/25 -- Good evening. Periodically, the Wallpaper option that's available when you have a new tab opened is NOT THERE. I've used your backgrounds and sometimes my own. But out of the blue, a new tab will have no background picture and when I use the pencil to open the menu, there are no wallpapers showing.

I don't see a reason for this, particularly since I haven't changed anything and no one else has access. This is a Dell Desktop, XPS 8960, fully loaded, enough of everything and running on Win 11.

So - are there limits to the graphic size used for a background? Would this be caused by a FF update? So many questions, and thanks for answering them.

BTW - I can't select the EM box below, so just send to me at: [edited email from public community support forum]

Hey everyone, I’m working on my website, lewisestimating.com, and I’ve hit a wall. Everything looks fine in Chrome and Edge, but in Firefox some parts of the layout don’t show up right. Images are out of place and a few buttons aren’t behaving like they should.

I’ve tried clearing cache, disabling extensions, and testing in private mode, but it’s still the same. Has anyone had this happen when working on their own site? Any tips on what I should check or tools in Firefox that can help me figure this out?

Would really appreciate any advice or suggestions.

do know computers very well, have used firefox for all my web browsing, firefox kept crashing according to screen so it opened saved apparent older version and I lost all my bookmarks and passwords, please help

At about 9 AM EST, 11/12, Firefox did an update that rendered accessibility through my voice navigation software inoperable. I need to use this to navigate the web due to disabilities with my hands. The system could no longer recognize any thing buttons or words on webpages, including the Firefox tabs at the top left of screen. I posted a question about this on 11/13. Later that afternoon, the functionality was restored. However, this morning, 11/13, this functionality has vanished again. Can this please be restored? Something obviously went awry in the coding with this most recent update. Thank you.

I recently asked a question about having a problem with Firefox not successfully loading a second webpage tab. While it appears to start loading correctly in a new tab the tab remains a blank page and the address window continues to appear that the loading process is ongoing but it just continues to show the apparent loading process but the network has no activity. I tried following some suggestions but to no avail. I then uninstalled Firefox and did a clean, new install. Upon trying the new install it appeared to work correctly at first but after attempted to do a second Google image search, which worked correctly, I tried to visit the site that what contained the original image. The site partially loaded; appeared to keep loading for about 15 minutes; stopped; and I got a partially installed page and even that wasn’t correct as can be seen in the enclosed images.

I need to know how I can stop my overflow bar from appearing whenever I click off and then back onto FireFox.

Steps to recreate starting in FireFox: 1. Click on an application other than FireFox 2. Click back on FireFox and then the overflow menu appears 3. Click anywhere on your FireFox window and it vanishes until step 1 & 2 are repeated

Apologies if this is the wrong place to ask this because I'm at my wits end on this one. I work on an app that is used by a large amount of users. Starting october 14th around 7am (UTC+1) we started observing weird behavior where a small ammount of traffic (less that 1%) would have abnormal header values:

'custom-header-1':'[custom value], [custom value of a different header]'; 'custom-header-2':'[custome value of header 2], u=4'; 'sec-fetch-site':'cors'; 'priority':'same-origin'; 'sec-fetch-mode':'empty';

As you can see the values of these headers are mixed with one another in almost a deliberate manner (since it appended the u=4 with a comma separator and a space from the priority into the custom header 2 value). There is nothing in the client code that would do this kind of manipulation, and from examining the logs this only happens on Mozilla browser traffic starting version 144 (which was released on October 14th coincidentally). Not that this does not impact all Firefox traffic. In fact, just a tiny fraction of traffic from random users and it's not even all of their traffic of an active session. Just random requests that then fail, are retried and the abnormal headers are gone.

I doubt the fault lies in firefox. If I had to hazard a guess it's probably some extension acting up, but the timing coinciding with the release of 144 give me the only troubleshooting path I have right now since contacting the users is not possible. We've seen it happen 145 as well.

I'm not really looking for a solution here, just a shot in the dark if someone else has experienced this or has some insight as of what this could be.
