Firefox Community Forum

I upgraded my Dell PC to Windows 11 yesterday via Windows Update, since support for Windows 10 is ending. Now Firefox crashes often when I close the browser. Everything works fine while I'm using Firefox, it's only when I close the browser that sometime later I will get a crash message on my desktop. I have tried uninstalling Firefox and reinstalling it, and the problem persists. From what I can tell, there's some process which is ongoing after the browser is closed, which isn't terminating properly and that's why it's crashing. I have submitted several crash reports, but don't know how to post them here.[bp-2e2d8f06-4c87-43a6-8b32-b0f5a0251006]

Firefox repeatedly crashes on my, multiple times a day. I'dc really like to NOT have to change my default browser to Chrome.

What happens is that Firefox freezes, and I get a white bar at the top telling me so. I get a popup box asking if I want to close Firefox or wait for it to respond. Waiting doesn't work, so I always have to close Firefox. When I reopen it, fortunately all m,y open tabs are retained, but it crashes again within minutes or seconds as soon as I click on anything.

There only thing that seems to work is a reboot of my PC. But the respite is short before Firefox crashes again.

I've disabled most plugins, but that hasn't helped. Is there a way to create an event log within Firefox that I can share with someone at Mozilla to help e debug the issue? It's got to be something local rather than Firefox itself; I can't imagine this is happening to most users.

I think that i get some virus in my computer, in the last two days some of my accounts were accessed by an unusual way.

I´d like to know if the problem was my passwords kept on firefox, all the apps that were hacked had the password saved on the firefox manager.

There's a way to know if my passwords on the Firefox were stolen ?

I just had to sign in to this forum although I had never logged out. I am using Firefox 143.0.3 (64-bit) on Linux Mint 22.2. It is not the first time I am having to login again in one-by-one the sites I visit. And before anything else, I have not changed any of my privacy settings and no new profile has been created due corruption of my default one. It is not the first time this happens lately. Any chance with the Firefox update? I think I installed one quite recently.

Hello, I imported Bookmarks when I came to Firefox from a previous browser. The experience was terrible and challenges still linger. Firefox has come a long way, however UX still seems to be a 2nd class citizen. Bookmarks now has somewhat duplicate directories and this in turn is causing desktop/phone sync doubt and is likely missing bookmarks.

When sync breaks, it is so confusing. How can I simply have a working Bookmarks sync on desktop/phone?

Perhaps there was a challenge when I need Bookmarks to appear in the top bar when a new Tab is opened, as this was contrary to default Firefox settings.

Hello everyone.

When opening an image in a new tab, I get an image with a glitch in the background (attached). I've read forums and websites, thought about it, tried the suggested options with commands to disable certain settings, tried installing Firefox forks – nothing helps. The persistent stripes continue to haunt me. Then I installed a couple of other browsers to compare and verify. The same issue doesn't exist in them. In short, I've racked my brain trying to solve this problem.

I need your help and ideas on how to overcome this.

Thank you. Sincerely, Alex.

I have the following in stock: i5-10400F CPU @ 2.90GHz 32.0 GB RAM 64-bit operating system, x64 processor Windows 10 Pro Edition Version 22H2 OS Build 19045.2673 Graphics Card: ASUS DUAL-RTX5060-O8G

Hello, My firefox, I have from top to bottom, Tabs bar, search bar, bookmarks My problem is that the tabs are very large. I don't know how I did this.. partially because I had to enlarge type.. I like tabs to show what I'm on and go back and forth sometimes but would like to get them smaller. is that possible? IE: my Home button shows up as a Tab, so I can't even x out of it without firefox closing. I always thought my home button was just beside my bookmarks.. Oh well.. if someone has any ideas, please let me know.. Thanks in advance, Linda

Previously when you click the ADD ON button a list of extension icons appeared but not if you click ADD ON button a theme tab pops up Now I can not use the extension I want to use eg for video download I could click the downloader icon and the video would start downloading. Now as the list is gone how do you use the down load ext if the icons are not listed. It is now a useless browser as I could not use the extension Even a simple eraser history icon is not there so I had to go to settings to clear data Very inconvenient Before you click the eraser button and history is cleared by 1 click Please restore ADD ON list button to make the browser more convenient as b4. After the recent update all the features are not visible

Does anyone know how to get rid of that icon in tabs with the newest version? I have found several mentions of code like below, but they are anywhere from 7 months ago to years ago and don't seem to work with the new update:

/* Disable unmuted icon */ .tab-audio-button { display:none !important; }/* Disable unmuted icon */ or .tab-audio-button { display:none !important; }

or something with: .tab-icon-overlay

thanks!

Hello. I've recently upgrade my internet connection (from fiber 200 to fiber 500 now), and I've noticed that firefox is slower than other browser like chrome, brave, edge etc.... The same was happened before so I didn't pay so much attention until the day I made the speedtest. The results was somehow disappointing (made the test multiple times, and days) I've made the test with or without extensions, same problem. I've check also that No Proxy setting is enabled. I've tried the firefox refresh, same results.

Can you please help? Mike

I've noticed that I've got both the 32 bit (../Program Files (86)/..) and 64 bit versions (../Program Files/..) of Firefox installed on my pc. I didn't install both and both appear to be the current version. Is this normal behaviour? Only one instance appears in add/remove programs, but if I go to default apps, Firefox appears twice (presumably the 32 & 64 bit versions). If this is not normal, does anyone have a suggestion as to how to remove the 32 bit version without damaging the 64 bit one?

As has been mentioned many times before I am sure, it would be really helpful to be able to have a less laborious way to add exceptions but as I have been through the ridiculous process of typing in site addresses manually one by one without having any sensible way to record these addresses already I guess it won't help me now. The ridiculous aspect came from having to take screen shots of the list of sites from the manage data list after deleting everything not wanted, scrolling down a windows worth at a time, copying that screen shot into multiple copies of a graphics program then shrinking each copy of the graphics program and Firefox so each can be seen so I can manually type each address across.

I know I am supposed to be nice but this is just insane. It is 2025. There is a thing called copy and paste. Apparently some people at Mozilla are not aware of this.

Having got that off my chest the next issue is that the deletion of cookies and data only occurs when Firefox is closed. Who closes Firefox? Why would you close Firefox? I currently have 24 tabs open. Why on earth would I want to close them down just so they have to be selected one at a time and reloaded? What is the thinking behind this stupidity?

The only time I close Firefox down is when Windows is restarted for updates (every application) or when IDM needs to update as I found this negates the need to restart Windows (Firefox only).

Other than those situations I am trying to work out how to fit this cookies/data deletion into the normal operation of my computer. There appears to be a lack of a suitable way to deal with this situation. Would it be considered acceptable to just wait for those times Firefox has to be closed? This would be far better than what I have been doing up to now but why wouldn't Firefox delete this data when the last tab for a site is closed? There are a huge number of sites I bring up due to searching for something and close them immediately or after reading what they have to say.

I have been using computers for about 30 years and have long lost the inclination and to be honest the ability to delve deep into them. Today I just want to have them do what I want/need without unnecessary complications.

Have I got this situation right or is there something I have missed? At the moment IDM has been having a lot of updates thanks to YouTube's greed but before that I found I generally only had to restart my computer for MS updates and when strange things started to happen.

When I hit 'enter' in Firefox, the search request is deleted. i uninstalled/reinstalled Firefox but the problem persists.

Firefox 143.0.4 (64-bit) Mac OS 15.6.1 (24G90)

bold text i cannot see the new tabs since they are way too small now. Yesterday they were fine but now they are made for people with normal vision not half blind people like me. Your help button is totally useless and made for people that are programmers. NOT for normal people like me. I just cant see very well and shouldnt need to use a magnifier to read the tabs and seach bar along with my bookmark bar. I can see they web pages fine but I need to see the things above that. It was working fine yesterday but some idiot who doesnt with good vision who is ignorant about people without good vision

Been trying to retrieve misplaced bookmark folders not bookmarks themselves in the Bookmarks Library with no success even going down several sub-levels; Would be nice if there were a search function, but will take a step-by-step solution. Thanks!

After easy semi-automatic updates for many years, the last two updates (143.0.3 and 143.0.4 on Windows 10 64bit) have stuck showing "Downloading update -- 0 bytes" for hours. The first time I eventually gave up and used the installer from the Firefox site to re-install. This seemed to get me to 143.0.3 without losing any important data in my profile but was certainly the hard way!

Now the same thing is happening during the update to 143.0.4. What's going on? Are other users having this problem? -- jclarkw

P.S. -- How can you manually stop and update during the download process? -- jclarkw
