I'm having Firefox browser problems. I checked on my computer for system updates and I am current. Pages are not loading, I'm just getting the blue dot swaying back and forth from right to left and left to right. I tried to clear out my chache and wonder if I did something wrong when I did that.

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,

When the option to sync is present, why doesn't it actually sync all regular settings across multiple devices. Why do I still need to perform extra work, on par with a lobotomy, to get everything exactly as it needs to be? And why is the toolbar customization not in Settings?

You do realize that most people search for SETTINGS when they want to change any aspect of a thing. But you have right-click context menus that nobody knows exist.

At this point, maybe Edge is the better browser. Firefox makes a lot of assumptions of its users. I shouldn't have to meticulously keep track of every single piece of information AFTER a sync to make sure it's all there. It should just exist.

This includes toolbar customization, Home tabs/button setup (I have 3 regular tabs I use, and those did not translate over), Theme (regardless of the system wide theme, because it's already set on the core machine).

I don't enjoy having to google how to use your browser.

For the past 2 months I've found it very difficult to sign into my Hotmail account using Firefox. Microsoft keep telling me to use a VPN or another device. I like answering emails on my computer because of its large screen. I've tried signing in about 2000 times now. Firefox told me they can't help me because I'm not a Mozilla subscriber even though they own Firefox. Microsoft told me it's Mozilla's problem. Can anyone help me please. John in the Philippines.

Hello, I'm experiencing a problem where my website fails to load in the Firefox browser on some devices. I've thoroughly checked things on my end and reviewed the website settings, but I haven't been able to identify the cause.

I've tested it across multiple devices and internet connections, and the site works perfectly on other browsers like Google Chrome and Microsoft Edge. But when trying to access it through Firefox, the site just gets stuck and doesn’t load at all.

I’ve already attempted a few troubleshooting steps, such as disabling browser extensions, clearing cookies and cache, and restarting Firefox, but unfortunately, none of those worked.

Is there anything else I can try to fix this? Or could someone from the support team look into it? Any help or guidance would be greatly appreciated.

Thanks in advance!

Using Windows 11 pc Firefox

When I click in search bar, the bar box expands to 2 rows, and "AP News apnews.com" appears in the second row of the search bar - within the search bar. It does not appear outside of the search bar. The rest of the page is totally blank per my preferences. The AP link is not included in my list of extensions, and I have no add-ons. I do not subscribe to AP News. It is not a resource I use.

Hi,

Firefox version: 139.0.4 (64-bit) OS: Windows 11

I have been having issues where Firefox tab will just crash out for no reason it appears and it happens at random times and once the tab start to crash, and I restore it, it will crash again and again. The only way tog et out of the loop is to restart Firefox.

I have tried: Refreshing/Reset, Clearing Cache and History removing all themes, disabling extensions, disabling my anti virus. Turning off hardware acceleration didn't make any different.

I currently have 2 extensions enabled: uBlock Origin 1.64.0 and Bitwarden Password Manager 2025.5.0

In the about:Crashes I have reported them all and they seem to have the same type of reasons in the Raw data/Minidump which are: EXCEPTION_ACCESS_VIOLATION_WRITE EXCEPTION_ACCESS_VIOLATION_READ

Any help as to what to try next?

When using Outlook365 Online, about 2 or 3 weeks ago the spell checking stopped working. I checked to see if this was a Microsoft account issue and it is not because when I move to Chrome the spell check works. I am running Windows 11 Pro, it is fully up-dated. I have all of the latest Firefox updates as well. I have looked at several online help articles and have done all of the suggested fixes. The spell check is turned on in Firefox. I believe with a recent up-date of Firefox, as they come regularly it triggered the issue. When using other apps, and websites the spell check works fine just not with any 365 Online product. I do have Office 19 installed on my computer which I use off line.

Hello Mozilla Support Team,

I’m experiencing an issue when attempting to drag and drop images directly from Firefox to my desktop in Windows 11 Pro (build 26100.4652) using Firefox 140.0.4 (64‑bit). Instead of successfully transferring the file, a “Ø” symbol appears, and the drop fails—no image is saved. What I’ve tried so far:

   Set UAC to the lowest setting.

   Launched Firefox via the -no-deelevate command.

   Verified no elevated launcher process is active.

   Tried on multiple folders including Desktop, Documents, etc.

System Details:

   OS Version: Windows 11 Pro 26100.4652

   Firefox Version: 140.0.4 (64‑bit)

Could you please assist in resolving this? Thanks!

I had to do an OS reset on my Dell Inspiron 17 3000. This deleted all my data files. A computer repair shop used Recuvr to recover my lost data. All of the recovered files (not just the Firefox files) are in a single folder on my desktop. I would like to know how to import them to the newly installed Firefox. Thank you very much.
