I updated Firefox to version 138 yesterday(29rd April). I use latest stable version of Linux Ubuntu. Sites itself will work, but top of browser wont. Can click open new tab from +-button, but can't close it.

Browser stops reacting to mouse clicks when browsing (after hours of browsing) and I have to use right-click to navigate on sites.... until I restart browser. I tried to close tab and refresh tab when these problems occurred. Also, this occurs on all sites.

I think this is clearly browser problem(because clicked areas are on browser, not inside tabs), not problem in sites itself, because problem manifested itself after hours of browsing, not immediately.

Edit: I'm not well-versed enough to write Bugzilla-report. Also in 138.0.1-1 version, where I updated 3rd May 2025.

Edit 2: I've added picture of area that stops working. Edit 3: On another picture, can't close "Archaeology" tab, no matter what. Edit 4: Clarified things up.

After Update to 138.0 my sideabar (bookmarks) is away. I can reactivate the sidebar on the left side as wished. But when I open a new Firefos Window or Tab the sidebar ist away again. What have they done, mozilla ?? How can I get mey bookmarks ALWAYS shown on left side of any Window or tab ?

I intended to change the language setting in my browser temporarily from English to Swedish. But now I cannot change it back to English. I see the option and I click on it but it does not do anything. I cannot even take away Swedish (svenska) as a language.

MY FF recently updated to version 1380.1 (64bits) and my Sidebar Bookmarks are gone. That is I have to manually put them back every time I now start FF. I want them to always show when I start FF. When I need extra screen space, I would click the X and they'd disappear for that session. And when I was done, I'd click on View - Bookmarks they'd be reinstalled. And when I shut FF down and returned later, they'd be right there where I need them.

My question is, how do I get back to that setup?

Starting this morning, I am constantly receiving pop ups supposedly from Mozilla regarding viruses. It says "click here to fix the error" Are these legit?

I have run my anti-virus and malware and they show nothing. I also have pop ups blocked.

Is it possible to restore firefox to a previous version to recover all my data? After update, all my firefox pages, tabs, bookmarks and history have vanished. Please help me recover or restore. Thank you!

Since the Firefox update, the Firefox window automatically expands to fill the entire desktop of my computer. I don't like that. I've reduced the size of the window multiple times, but it keeps expanding again. How can I fix this?

Firefox no longer allows me to bookmark web sites that I want for place in my bookmark folders. I have encountered several situation when trying to bookmark a web site:

1- When I get to a site that I want to bookmark, I go to "Bookmarks", select and click on "Bookmark Current Tab" and nothing happens. On prior versions of Firefox, another panel would be presented where I would have the option to file the current tab to an existing Firefox folder or create an new folder.

Now I do not have that option available to me. These problems seems to to have started with the upgrade to 134.0.2

2- When I go to "Bookmarks" and select "Manage Bookmarks" I am able to see a listing of of the bookmarks but the list is not complete. I have preciously established and used the bookmark labeled as "Woodworking" which is no longer present, in fact the the last alphabetical listed bookmark is "Ryobi".

I did have and was able to use the bookmark "Woodworking" in the past. Why is everything beyond "Ryobi missing?

3 - Some times when I go to use bookmarks it does show provide me with the panel that would allow me to bookmark the current tab but it will not allow me to create a new folder where I want to place the current tab..

4 -I have tried to go to an older version of Firefox but have been unable to locate where I can obtain it. Would going back to an older version resolve my issues and if so where can I get an older version?

I have been using Firefox for many years and never had issues and have been very happy with it. Anything guidance you can provide to resolve these bookmark issues would be greatly appreciated.

Thanks in advance,

Victor

I've just updated Firefox to 136.0 and found the "return closed tab" key became blank and ineffective. I read the update log but didn't find infomation about this change. The function was useful to me and I hope to get it back.

Since updating to version 135 all the tabs crash. I've uninstalled\reinstalled, deleted app data, disabled AV and created a new profile. The only time it works is in troubleshooting mode. I've looked at extensions and plugins and I'm only seeing OpenH264 video codec and Widevine content decryption. I've disabled those but still get the crashed tabs.

I'm also not generating any crash logs.
