For some reason after I restarted my laptop (firefox was opened) Mozilla was reset. I was logout from my acc and also firefox isn't my default browser (I didnt anything with it). Btw if I tried to open any link system will open it via firefox. But firefox still said that its not default browser in system. And if I open default apps in Windows I have 2 firefox there (and both recommend me to set is as default). Except FF I have only edge that also said that I can set is as default. After I login in my acc in firefox I haven't anything. No history, no passwords, extensions etc. What I can do here? I tried to use sync but as result I still have nothing.

Never cough smth like this before in same cases.

I have changed operating systems from windows to linux mint. I made sure to sync my profile before uninstalling, but now the profile looks to be empty. there are no saved passwords or bookmarks. This worked when I changed between different windows devices last year, but this time it seems stuck. I will check on a windows device when able, but in the meantime, are there any other ways to troubleshoot this?

When is do a search in Firefox I noticed that it now searches with "rini.drorinat.com" is this still Firefox or have I been violated? I tried to look up this site but no success, could you help with this asap please?

Suddenly, Firefox is not auto-filling my passwords. I am experienced, and have gone over all settings multiple times. It is requiring me to click "manage passwords" and then copy from my saved passwords, and paste in the password, instead of auto-filling.

Since a few days, Firefox started crashing each time I receive a notification.

For example, with this notifications test website: https://www.bennish.net/web-notifications.html

Each time I click on the "Show" button to display a notification, Firefox becomes completely unresponsive: the content of the window is completely frozen and I can't click on anything. I must close it and restart it to make it work again. When I restart it, a dialog displays:

> Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window.

In both applications, the notification is never shown: the freeze occurs before.

I tried the following changes but they did not stop the issue from occuring:

- Deactivating hardware acceleration - Troubleshooting mode - Deactivating firefox notifications in Windows - Deactivating `alerts.useSystemBackend` and `alerts.useSystemBackend.windows.notificationserver.enabled` in `about:config`

At the same time, I noticed that Thunderbird (v144.0.1, 64bits) started having the same issue. It haappens each time I receive a new message in the background and a notification should appear. Maybe this is related?

My Surface Laptop 7 w/ SnapDragon Elite's Firefox installation started crashing this morning immediately after rebooting to complete some Windows updates. I have attempted starting Firefox in Maintenance mode, Uninstalled and reinstalled and I still get the crash reporter. Refreshing Firefox at the uninstall process does not fix it.

I'm running Windows 11 Enterprise edition, fully patched w/ Firefox 146.0.

The 4 Windows updates that were installed:

Uninstalled KB5072033 Uninstalled KB5070311 Cannot be uninstalled KB5072641 Cannot be uninstalled KB5071142

Still didn't fix the problem.

These are the recent crash reports:

Crash ID: ⁨bp-8ec5b63c-4408-437c-b9bb-f4d5b0251213⁩ Crash ID: ⁨bp-ce396463-0a75-46b6-8131-33cce0251213⁩ Crash ID: ⁨bp-ea0b59dd-1cee-48da-957e-949120251213⁩ Crash ID: ⁨bp-f9342e01-1a55-4387-af6d-3b8ef0251213⁩

Any help is appreciated!

I run the current Firefox version under Windows 11 Pro on a Dell Inspiron 15 3530 laptop, Lately, I've been having problems with my bookmarks:

• First, I found that I had somehow lost a large number of bookmark tags; it took me several days to restore them,
• Next, I found that I had lost a bunch of bookmark subfolders; the bookmarks (for the most part) are still listed under their tags.
• When I try searching for tags in Bookmarks Manager, the search yield no results
• When I try to restore my bookmarks from a previous date, I get an "unable to process file" message.
• When I try to open the profile folder through the debugging information page, I get a "file not found" message. After some searching, I found the profile folder not at "C:\Users\croge\AppData\Roaming\Mozilla\Firefox\Profiles\7csymh5k.default-release", but at "C:\Users\croge\AppData\Local\Packages\Mozilla.Firefox_n80bbvh6b1yt2\LocalCache\Roaming\Mozilla\Firefox\Profiles", Something seems to have gone haywire--did I miss something, or is there an error somewhere?

Firefox 146.0.1 crashes every time upon launch (basically fails to launch), even in troubleshooting mode, with exception code 0xc0000005. Prior to today, it was working fine. Windows does not show any updates made over the last couple of days. I am on Windows 11 25H2, and I'm current with updates. Chrome works. Edge works. I logged on to the same computer as a different user (different profile folder in the user AppData folder) and Firefox still does not work. I tried to refresh Firefox and that did not resolve the issue. I tried to uninstall and reinstall Firefox and that did not resolve the issue. I tried to run DISM and SCANNOW and that did not resolve the issue. No issues are detected with a virus scan. I am stumped - please help!

I typically use FF to log into social security accounts. I have not been able to use FF for a couple of months to log in to ONLY THAT SITE. I can on CHROME.

Hi, I just want to ask about the customization option on the new tab's low right corner (the little pencil icon). I've had a background image called "Galaxy" that i thought was pretty, but it disappeared (probably sync settings on other devices, idc) and now the background is just system gray. The issue is that i cannot find the system background in "Themes" nor in the "Customization" (picrel) - there is only "reset to defaults". I really like Firefox and this was pretty cool so I'd like it back. Thanks in advance :)

I am unable to print after upgrade to ver 144.0 The print preview just spins. I can print these web pages using Edge. This same thing happens with new version of Thunderbird. Can't print email either. John Stark

Since Firefox automatically updated (14.0.1) on my MacBook Air (2025 model) several weeks ago, the Bookmarks and History functions haven't worked. Can anyone suggest how I can fix this?
