Firefox Community Forum

Hi Mozilla Community,

I am running Firefox on Windows 11 and I'm encountering a strange issue regarding the UI updates.

The Issue: My Firefox browser updates automatically to the latest version. However, my Default Profile is visually stuck on the old UI design. It does not reflect the recent interface changes associated with the update.

The Troubleshooting Context:

• I have verified that the browser itself is technically updated (via Help > About Firefox).
• The strange part: I have other Firefox profiles on this same machine. When I launch those profiles, they correctly display the new, updated UI.
• This issue is isolated strictly to my main/default profile.

Has anyone experienced this mismatch where the version number is correct, but the UI fails to refresh on a specific profile? Is there a specific fix for this?

Thanks in advance for the help.

I started using the new "Profiles" feature in firefox, and I created profiles one one device. However I am finding that the profiles are not syncing across my devices. Both are Windows 11 VMs, I tried doing manual syncs, singed out and back in to both devices. But the Profiles I create on each just do not seem to sync, is this the expected behavior ?

Bookmarks in Firefox disappeared and cannot import my Bookmarks backup. I have tried to restore an older Bookmark file through /manage bookmarks/ import and backup/restore to no avail. thank you

cleaning up my computer, I accidentally deleted firefox. I had a list of favourite links, and I lost them. Is there any way of recovering my list of favourites?

thank you, Glen A Goodale, [email removed]@gmail.com

When I watch videos (reels) on Facebook, and sometimes on YouTube, I share a video either to messenger or my page, the whole string of videos I have already watched goes back to the beginning of the string everytime. Only Firefox does this. I have 3 other browsers that work fine, but I prefer Firefox of course.

I'd appreciate a fix for this, Thanks

I own three laptops and they are in my Firefox account and synced. I have several bookmarks for site I frequently visit. On two laptops, based on my settings, when I tap a bookmark it opens up in its own tab. This is how I want these to function. For some reason, my third laptop does not behave in this manner. The new bookmark opens up on the tab I am currently in. It gets bumped and the new bookmark opens. This is exactly how I do not want it to perform. What is going on? Also, when I set up settings doesn't it work for all my laptops since I am signed in?

My emails used to display in date order but since a Mozilla upgrade they are now grouped as Today, Yesterday and Last Week. Is there a setting to alter this back to one list in date order please?

Why can't anyone fix this issue? Every day I have to go to about:config, enter "mica" then change from false to true or true to false to get these buttons to show up. It's ridiculous. I am currently using Firefox version 146.1 on Windows 11. Also, please note if I change the windows widget to true these buttons show up and are usable. The next days I have to change the windows widget to false and they show up and are usable so they work whether or not the widget is set to true or false. The problem is having to change the setting DAILY. I should not be having to do this.

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?

My friend recommended this browser to me. When I tried to customize it, I couldn't find an option to change the hotkeys to my preference. I consider this feature important since I use it for work. Can I do this somehow, and is there any plan to add such a feature to the settings?

When I try to log in to my account with Amazon Prime, Firefox freezes as soon as I hit the Continue button after entering the username and password. I can't open or close tabs or do anything. I don't have this problem with the Amazon account in any other browser.

Any ideas why this happens and how to fix it?

Problem started with Firefox 146.0.1 Windows 11

1. Open outlook.com in FF browser (https://outlook.live.com/mail/0/). 2. Open any email. 3. No side scrollbar appears so you can't page down within email. Note: the Outlook folder scrollbar does appear and does work. 4. The within-email-item side scroll bar does appear from outlook.com opened in Edge browser. So this is a Firefox bug.

Have tried: a. Windows settings->Accessibility->Visual effects->Always show scrollbars = on b. Turned Adblock on and off for outlook.com c. Firefox settings autoscrolling, smooth scrolling tried all combinations.

Any fixes?
