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.

When v143 was released something happened to the shortcuts row(s). Regardless of refreshing efforts, rolling back versions, and searching the forums, there's no way to consistently get the shortcuts back. Sometimes they appear with a new browser instance, sometimes they don't. They don't appear with new tabs, and they don't stay when they do appear with a new browser. Grrrr. Please restore the shortcuts!

My bookmarks toolbar is showing, but it's empty. All of my bookmarks are gone.

I went to a websites and attempted to add it to my bookmarks toolbar, but Firefox failed to add it to my toolbar.

My homepage saved sites are just not showing anymore when I start Mozilla or open a new tab. They are still saved but they are not showing up at all, I have checked about:config and everything is still there. I have tried following things: 1. restart Mozilla 2. restart PC 3. refresh Mozilla (this worked... for 1 day, I had to manually put all the saved sites again but they again disappeared when I turned on PC the next day)

However, if I enter troubleshoot mode, everything is still there and working. So I assumed it is an extension or a theme problem, which would be a great solve if I had any really. I have no extensions and I use the same basic theme that I start with. So I tried disabling hardware acceleration, didn't work. I am running out of ideas really other than switching to Chrome at this point.

Attaching files to show the issue. Not shown is the regular mode, the shown one is the troubleshoot mode

I have no idea what has changed and I do not have the experience to attempt to figure it out. I have had Dashlane for years and it works like a charm. Now, it will not auto fill certain sites and with other there is some sort of conflict which causes the sites to sit and spin but it will not auto-fill like usual.

All I have done is clear the cashe several times and then it started. Its a brand new machine so not sure how that plays into it but it was all of a sudden out of no where.

Any help would be greatly appreciated.

Hi, Since the last update for Mozilla on the laptop (updated on 6/Oct/2025 - version 143.0.4 (64-bit)), all the shortcuts to websites in Firefox homepage I had pinned have disappeared. Also I can't add new shortcuts. I already have shortcuts enabled in Settings>Home>Firefox Home Content>Shortcuts.

Does anyone know how to solve this?

Kind regards.

Hi! I'm experiencing a strange issue with Firefox.

Every time I start Firefox, the site addons.mozilla.org opens automatically — and it opens in fullscreen mode (as if I pressed F11). Here's what I've tried so far:

I disabled all extensions, but the problem still persists.

I changed the homepage settings to a blank page and even other websites, but it doesn't help — addons.mozilla.org still opens.

The issue happens even after restarting the computer.

I haven't reinstalled Firefox yet — I’d like to understand what might be causing this first.

Any help or suggestions would be appreciated!

I'm not able to uninstall PWA apps created in Firefox 143.0.1 using Windows 11 usual uninstalling procedure. If i click "uninstall" in Windows Start Menu the app remains installed. PWA apps created with Firefox do not show on Windows 11 installed apps list so I cannot uninstall them. I haven't found any guide on the web on how to uninstall PWA created from Firefox. So, how can I effectively uninstall those PWA apps? Thank you in advance for your kind answer. Regards.

Please let me know how to get my favorite sites back on my home screen. I use them a lot as they are real time savers. When I signed on this morning, it asked if I wanted Firefox to access my computer. I've always said yes and the updates have never caused a problem - until today.

I would appreciate an email ([edited email from community support forum]) letting me know how to get this to work.

I deleted all the shortcuts from Firefox desktop browser's homepage and now I cannot add them back.

There are no blank shortcut icons on the page anymore. No setting to enable them. Shortcuts are enabled. Page is mostly blank, only has Firefox icon.

I tried to close and open Firefox as well as disabling and enabling the shortcut setting. Adding more rows did not do anything.

Before this issue occurred, I had one shortcut on the page that was linking to localhost. I opened the edit window to the shortcut and pasted the same address and saved changes. After that I removed the shortcut. All of the blank tiles immediately got removed from page and I had no way of adding more shortcuts.

The favicons on my homepage are not appearing when I launch Firefox, and I can't find any way to restore them. Turning the favicons on/off in the settings doesn't help, it just moves the location of the search bar. I've included some images to better illustrate the problem.

Is there any way we can restore the favicons?

I opened Firefox this morning and all of my pinned shortcuts have disappeared. Shortcuts are enabled in the settings. I checked the browser.newtabpage.pinned pref on the about:config and all of my pinned shortcuts are still there, but they're not appearing on the actual page itself. Are there any other settings that I'm not aware of?

Hello, Firefox won't save my download history between sessions, history is set to remember. I tried doing the refresh on the installer and even reinstalling firefox and deleting all mozilla folders in %localappdata% and %appdata% before reinstalling. it just forgets all downloads once I close firefox.

Good morning,

Firefox is not loading webpages correctly this morning. From Gmail not displaying or opening individual emails, Amazon not opening, to Youtube and several other sites not loading or displaying correctly. I had no issues at 9 PM PDT yesterday.

No changes to the computer, and everything is up to date.

I have successfully opened the above mentioned sites and others on MS Edge this morning.

Thanks!

Hello. I have a question. When I scan a PDF file in Firefox, it opens in a new window. Why? I don't mind it opening in a new tab, so I would prefer it to open in a tab.

I have various shortcuts saved on the shortcut page comes up after logging in. Its set to 2 rows.. I use it every day. Used it this morning and working perfectly. Been out and when I came back the page is totally blank. I've tried sytem restore to 5th October but makes no difference. I use Windows 10 and read that Firefox are continuing to support Windows 10 I'm visually impaired and use a desktop PC with a large screen. I'm not PC techically knowledgeable. How do I restore my shortcuts or how do I re create them?

Every time I update my drivers for Nvidia it of course reloads the screens. This causes all the tabs in Firefox to become separated on the Windows 11 taskbar. In other words, it looks like I have a new firefox window open for each tab (which I'm assuming is how it works but it's hidden most of the time).

It's not a HUGE deal per se, but it is kind of annoying. I have to close then reopen Firefox.
