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.

I thought I was just upgrading my Mozilla/Firefox account account and now everything I had is gone. I had an automatic taskbar that went to most of my frequently used services like my bank, yahoo mail, etc. Now I have stupid stuff that I never use. Makes me want to switch to something else.

Hello! After a clean install of Windows 11 24h2 Pro, Mozilla Firefox is unusable. It takes about 2 minutes to load a page which is abnormal. I remember I had the same issue when I first installed Windows 11 23H2 Pro and that was resolved somehow but it was 2 or 3 years ago and I've no idea what the solution was back then. I've tried some basic stuff including Test suggestion which of course didn't resolve anything as almost all of them are referring to cleaning cache, reinstall Firefox etc and it literally has nothing to do with my situation. Any solutions?

I have Firefox installed on three Windows Desktop Computers. On one, I just cannot delete Bookmarks, no matter what suggestions I try. Verify Integrity of the database produced no results. I do not, for a variety of reasons, sync bookmarks (or anything else) between the three installations. Experienced user that has spent far too long on what should be a simple issue.

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

Something very bad happened to me today (11/3)....

Firefox 144.0.2 was installed on 10/30/25, and everything has been fine until today. I don't know why or how, but ALL of my OPEN tabs (of which I have many--and have it fixed so they always re-open when Firefox starts), ALL went away.

In reading conventional steps to recover such from sessionstore-backups, those instructions sounded straightforward. However, even though ALL FIREFOX PROCESSES were ended, I could not copy the contents of the sessionstore-backups folder nor could I delete anything--EVEN THOUGH I am the owner.

Even after providing Admin perms.

I could get rid of profiles.ini, which initially proved diasterous, because then Firefox thought I was brand new, so ALL of my passwords saved through Firefox these many years, went "poof".

Fortunately, I was able to get that back, but I still cannot get all of my tabs back, and conventional instructions to do so aren't working.

After recovering from my heart attack for initially losing my passwords, I am breathing a little better right now, but it sure would be nice to get all of my open tabs back again. I don't know why I am not able to manipulate the files within sessionstore-backups. I think if I could eliminate the files in that folder EXCEPT for upgrade.jsonlz4-20251027123126, which possesses a 10/29/25 date, these should be the open tabs just before the 144.0.2 installation, and all should be right with the world, once more.

I have performed/examined many steps offered under this category, but most assume I can copy them elsewhere for safe-keeping and/or removing all but the one I want Firefox to "use". Because something is preventing me from doing this, though, I am being stymied in what ought to be the solution. As a test, I was able to copy files from a much older profile--so I can prove the basic steps SHOULD HAVE worked. Unfortunately, I cannot do the same with THE (more recent) folder in question. I can't get rid of parent.lock, either (and I have ensured no Firefox processes are running via Task Manager).

Repeatedly.

Something else is at work, here. Any help or assistance from community experts would be most helpful.

Thanks very much in advance.

I updated to Firefox 141.0 and now Google Maps is not working correctly. When I look for directions the map does not show the route. If I go to street view I get a black screen. Google maps is working fine on Edge or Google on the same pc.

since I put my computer on windows 11, I cannot upload photos on my blog operated by wordpress with firefox. But it works perfectly well if I navigate with edge. Can you tell me why? I would prefer to continue to navigate with firefox but it does not work for loading my photos even if I compress them. I never had difficulties with windows 10 ...

When I view an item on Ebay this weekend, the images are not selectable (ie., an item that has 5 images will only show the 1st one in the main window, with no zoom or clickability). Firefox is my default browser, version is 143.0.1 (current), Windows 64-bit, and no ad-block extension is activated for that tab. Opened same pages/items in Bing, and images were accessible and selectable.

Since a month or so, Firefox browser freezes when playing youtube videos. Simply closing the app and restarting won't do the trick, I am forced to open the WIN Task Manager and manually "end task" before I can watch youtube videos again ... until an hour later, or lucky a day later, the same drama unfolds. I run the newest version of each, Firefox and Windows 11. No new extensions or plugins have been added recently. What is to do here? I'm since Netscape on this route and would hate to switch to another browser... :-) Thanks in advance!

I switched my default search engine from Google to Bing. As you can see in the attached screenshot, it should be searching with Bing. But for some reason the search results are always Google. How do I fix this? I haven't refreshed Firefox yet. I was hoping to avoid that.
