Firefox Community Forum

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.

What does this mean? being updated by another instance

Is this why my FF is running godawful slow today?

Pages coming up in 20 to 60 seconds or more instead of in a second or two.

I switched to Firefox a few months ago and I've been using the "about:profiles" page to mimic chrome's profile feature. I have 3 profiles, each with their own Mozilla account. How can I migrate these to the new profiles system?

Hi! I'm on a relatively new to me (refurb) desktop computer running Win 10 Pro (64 bit)* and Firefox 143.0.3.

In the past week both Firefox and Win 10 have updated. I don't know what happened, but now when I boot up or reboot, my computer opens to MS Edge. Yuck!

Every single time I have to reinstall Firefox! Once I do that, all is well again. I have all my bookmarks back, etc.

It also keeps changing my "default to Firefox" browser setting, turning it OFF, while I'm using Firefox. I repeatedly have to keep going in and clicking to make FF to the default browser again.

Why is it doing this? How do I stop it?

Anyway, I know I can't delete Edge or uninstall it. How do I shove it back into the black hole it has lived in until now?

Thanks very much in advance for any help offered. :)

[edit] I was using my phone to post this question and inadvertently posted it to the android forum. This is a DESKTOP question.

I'm trying to sync my tab groups across my desktop/laptop. I have sync enabled through the settings and I've checked every box, but I don't seem to see an option for syncing tab groups specifically. It syncs all of my bookmarks and active tabs, but the groups seem to be unique to each device. Is this feature available? I might be looking in the wrong spot so if anyone has any insight that would be great! Cheers

i got the new update but i have one problem. where is the home button on the toolbar? i would like to just press that like before instead of opening a new page and closing the old one

I made the mistake to following Mozilla's advice on why my tabs stopped coming back after I closed out, despite the fact that I had that selected in my settings. Now I'm stuck with an "Old Firefox Data" folder on my desktop and I can't remove it because I need administrator privileges -- but it's my personal PC. WTF

I have lost my tabs after the recent update. They used to show all tab groups in toolbar icon as mentioned here (https://support.mozilla.org/en-US/kb/tab-groups) in manage tabs section. Only the groups that were open are retained, the groups which were closed are lost. They contained important tabs which I haven't bookmarked. I didn't see any policy of removal of inactive tab groups after certain time, any help would be really appreciated. I use the desktop app on Linux.

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?

Hi,

I've recently removed Sidebery as a extension, as Firefox now offers a similar feature - I'm really happy for that. I'm using the sidebar with "Expand sidebar on hover" on three different computers, and notices it many times every day, that the sidebar doesn't expand when i hover my cursor over it. In that case, i usually press the sidebar button so it's expanded by default, waits a while and try again.

Sometimes i notice that it doesn't trigger when the firefox download section or history "pop-up" are open - it would be nice if it did, sometimes i need to move a downloaded file into a webpage on another tab, but can't remember what favicon - but that's not really the cause of this question.

Is there any way for me to debug the problem when it's bugging out? Or is it something known? I can't find any else complaining about it, but as said, it's on all three of my computers (Win11), which all of them have two different instances of Firefox (Normal Firefox and Dev Edition) which are all synced between computers, so all 6 browsers are "doing it", and i can't seem to find a pattern or a cause.
