Dear Firefox China Team, After reinstalling Windows on 2025-07-22 and installing I signed in with the same Firefox Account (this one). Unfortunately: • No bookmarks, passwords, history or extensions were restored. • I believe “Sync” was enabled before the reinstall with all data types selected. • The UI only shows “Syncing…” but no data appears. Please help:

   Check whether any sync data exists for this UID.
   • If yes, explain why it is not downloading and provide recovery steps.
   • If no, supply official evidence (e.g., server-side log) showing zero data.
   If my data (bookmarks, logins.json/key4.db, form history, add-ons) is on your servers, kindly export it to me in an encrypted archive or provide a temporary secure download link.
   Advise how to prevent this “appears-to-be-synced but actually not” scenario in the future (mandatory manual backup, verification methods, etc.).

Troubleshooting already done: – Confirmed same account, same email. – Reset services.sync.* prefs to default. – Manually triggered sync; about:sync-log shows no error codes. – Created a fresh profile; still empty. Please reply at your earliest convenience so I can continue using Firefox with confidence. I am ready to provide Sync ID or any logs you need. Best regards,

Up until recently Bing Maps in the UK has the option to display Ordnance Suvey Maps and the function to measure distance.

Now, using Firefox, Bing Maps display a Beta version with very limited functionality. Using Microsoft Edge, Bing Maps have all the functionality that I expect.

Has something changed within Firefox that has caused this problem? Is there something that can be done to allow Bing Maps to work correctly from within Firefox?

I set the about:config settings when I got the new computer early last year. It's been working fine. Suddenly, searches are popping up again to the urlbar.

browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar is still set to false. Keyword.enabled is still set to false.

I see a couple of site references to browser.fixup.alternate.enabled, but it doesn't exist.

How do I get FF back to proper search in the search bar?

Today, Firefox stopped playing audio on Facebook videos and won't play Netflix videos at all (Netflix error code: F7701-1003). Youtube works fine and has audio, but several other video sites I've tried have video but no audio. It was all working fine yesterday and I haven't changed any settings.

These websites work fine with both audio and sound on Microsoft Edge on the same laptop, so this is a problem exclusive to Firefox. OS is Windows 11 Home 23H2, Firefox is latest version (129.0.2)

Things I've tried: 1. Refresh Firefox settings 2. Download and install fresh copy of Firefox 3. Toggle DRM content in setting on/off - no difference no matter what is selected 4. Ensure that 'remember history' is selected 5. Check for Windows updates 6. Uninstall audio driver, restart and fresh install of audio driver 7. Ensure it's not in private mode 8. Turn off all extensions 9. Check volume mixer allows sound for Firefox 10. Clear the cache and cookies

I can't find any more suggestions on the internet, so any further suggestions welcome!

I have tried all fixes suggested by others reporting similar problems with previous versions, but this was noticeable for me yesterday afternoon right after some downtime and the latest version (for me) of Firefox was installed. Every time I try to use a site requiring recaptcha, the wheel spins and I get no choice to log in. I've cleared cookies and my cache, refreshed Firefox, etc. Nothing works.

Hello there, Iam facing a problem with changing Firefox homepage background. I tried every solution, tutorial, oldposts etc. nothing seems to work, here is what I tried. -1- The chrome folder is in the right folder. -2- the naming of both CSS files userChrome, userContent. -3- enabled CSS files at startup -4- search for both CSS files in the browser toolbox for some reason I cannot find both CSS files, even though they are in the chrome directory. Also, I have 2 chrome folders one of them is located here. "AppData\Roaming\Mozilla\Firefox\Profiles\shaf5qn0.default-release\storage\permanent\chrome" the other one I created myself which is here "AppData\Roaming\Mozilla\Firefox\Profiles\shaf5qn0.default-release\chrome" I tried to delete the first one but I cant, I get an error that this file is being used even though I did close Firefox. What I am missing here?

I was able to open reddit.com without any problems earlier, but recentrly I'm not able to load it up anymore. The loading screen is eternal and it doesnt show any kind of error (unless it tries to connect for too long like a couple of minutes, then the error does shows up). The site still sends me notificarions through the browser though. Any other site loads up without a problem. I tried to use methods mentioned in the help article (turned off proxy, turned on network.dns.disableIPv6, deleted cookies and cache). In other browsers (Edge, for example) reddit.com loads just fine. Please help me if you can.

It's not clear to me from the general help instructions how to get my passwords and bookmarks from my old computer to my new one. All the files from my old computer were transferred into one big folder and placed on the Desktop of my new computer. I don't know how to find the right file in the backup and where I need to copy it to on my new computer. I know a while ago I had to recover my passwords, but I forget the steps I went through and it was all on the same computer so slightly different situation although as I recall it was not all that difficult. Any help would be greatly appreciated.

In Firefox version 149, there is an issue with print preview behavior for HTML <select> elements. When opening print preview, all <option> items inside a dropdown are displayed and included in the print output.

This behavior differs from Firefox 148, where only the selected option is rendered correctly during print preview.

Steps to reproduce:

- Create an HTML page with a <select> dropdown containing multiple <option> elements. - Select one of the options. - Open print preview (Ctrl + P).

Expected result: Only the selected option should be visible and printed.

Actual result: All options inside the <select> element are displayed and printed.

Impact: This issue breaks the layout of printed documents and makes forms difficult to read, especially when dropdowns contain many options.

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!

Hi. I cannot use stripe payments. I am using FF vLatest and have added it to the popup blocker exception list and every other exception list I can find. I have done this for http://stripe.com and for whatever website is trying to use stripe. No stripe payments ever work and I always get the same error attached. I have tried another browser and it works. How can I find out at least what is blocking the payments so I can disable it?

For about a couple of weeks, there has been a lot of delay between what I type and when it actually appears. It's maddening! I have not changed any of my Firefox settings. I did a 'refresh' about an hour ago. I am not seeing any network activity that I cannot recognize. I d/l'd 'Malwarebytes' and ran it..."no threats". MS Defender has always been on & protecting me. I have never had this situation occur before and am hoping for some help (5 to 10 seconds to wait for what you've keyed in is not fun).

I have an website which I prior to this error message have visited many times on Firefox and had no problems. Recently though around two days ago I noticed that I couldn't get in and was met with the following message "Warning: Potential Security Risk Ahead". I can't bypass it apparently and I really need to be able to access this site as it's a University site.

I can access the site on other browsers such as Chrome and Edge but I use Firefox as my default browser and I'd like to keep it that way. I'd appreciate any help I can get.

Hi,

For some time now, when I download a .pptx, .xlsx og .docx Firefox changes the file format to .pdf when downloading the file. I then have to manually choose the correct app for opening the file, overrule error messages and delete the ".pdf" when re-saving the file even though it recognises it is not really a pdf file.

I've tried to change the Firefox settings, clearing cache, restarting or deleting in config and other small attempts to reboot whatever suddenly started to cause this problem. As far as I can see, it is not an unknown issue, but I've not yet been able to find a solution to my problem, which is getting on my nerves.

Hope you can be of help.
