Firefox Support Forum

This isn't a constant issue for me, but occasionally the browser will suddenly break such that when I switch tabs, nothing actually updates until I do something like restore/maximise the window. I can still interact with the page itself, but whether using the mouse or keyboard shortcuts, changing, opening, or closing tabs, or even typing in the navigation bar, won't do anything until I resize the window again. I haven't been able to figure out any pattern to when this state triggers, but after it does, it doesn't clear up without closing and reopening the browser. I have recorded a video showing this behavior but I am unable to upload it here, and still images would not properly convey the issue.

Tabs always start in mute mode. I can turn it on by pressing speaker logo in the tab. The problem is when I shift to a new tab, the previous tab mutes automatically. For example: I listen to YouTube music and want to check my mail. When I shift focus to the new tab the first mutes it self. Any suggestions please. Sincerely Oscar.

I can't turn off lazy loading. I set the following about:config settings to "false":

browser.sessionstore.restore_on_demand browser.sessionstore.restore_tabs_lazily browser.sessionstore.restore_pinned_tabs_on_demand

Nothing changes. When I start Firefox, it simply won't load all tabs. How do I fix this?

Every time I close my Firefox browser, the same tabs are restored after reopening the browser. I don't want that to happen. How can I get them to close completely? I'd still like the option to restore the tabs but not every time.

Hello.

Since some time (few months, can't really say when this started happening), the middle mouse button click on a tab stopped working as before. I will describe the expected behavior and how it (still) works on the same computer with a different browser (Chrome):

1. Hover over a tab 2. Middle-click closes a tab 3. Tabs right to the closed one move left 4. Middle-click closes a tab 5. Steps 2-4 may be repeated unless there are no tabs opened 6. Leaving the tabs bar (if any left opened) will now rearrange the remaining tabs (increase their width, etc)

Now, here is the not so great behavior I am facing in Firefox: 1. Hover over a tab 2. Middle-click closes a tab 3. Tabs right to the closed one move left 4. Middle-click rearranges the remaining tabs (increase their width, etc) 5. Middle-click closes a tab 6. Steps 2-5 may be repeated unless there are no tabs opened 7. Leaving the tabs bar (if any left opened) will now rearrange the remaining tabs (increase their width, etc), if you have left at last step 3

See, there is this extra step #4 which is really bugging me enough to actually come and ask for a support.

I am on Ubuntu 20.04, using latest version of Firefox (to date).

Many thanks!

Does Firefox answer questions about problems they have created!! This latest version of restore previous session has removed restore previous session with apparently no way of getting it back and Firefox has not answered the question as to why or how to fix the problem. Sad!!

When I open a new tab in Firefox it opens as a blank page - I have been all over the settings and can't get it to open to the firefox page. Can you fix that or tell me how to fix that so I don't get a blank page?

Have used Firefox for years, running tabs of info vital to me at top of page. Suddenly about 3-4 months ago Firefox wipes all the tabs clean every few weeks without any warning. This is seriously damaging to the work I do, and I urgently want to know what I must do to retrieve these tabs - or at the very least put a stop to the elimination of the these tabs? Thank you Christopher Dreyfus

In settings, Start-up, I have the box checked for: "open previous windows and tabs" but it doesn't work. In order to do my work I need the 23 tabs I currently have open to show up again after a reboot of the browser or computer. What gives? How long will it take to get this corrected? Please give me help. Thanks, Mark

I've tried everything and read all the instructions but none work.

I have lost my "home" icon so have to close and reopen or check history to go to my start page. Also, I can't play You Tube videos at the moment. The little house icon is missing. See screen shot.

When I open settings, under "start up" are only 2 options: 1. Open previous windows and tabs 2. Always check if Firefox is your default browser

There is no way to adjust which pages open when I open Firefox. What am I doing wrong here?

There are times when my browser doesn't let me close tabs. Whenever that happens, clicking on the X button does nothing and I've noticed that, when I try that, another layer of buttons appears briefly just over the Firefox window resizing and closing buttons; as if a new screen layer of unknown origins is blocking my actions. Closing the window, however, works normally.

This problem happens randomly and I have no idea what's causing, but it's getting annoying. How can I fix that?

I have bullseye (debian 11) and firefox-esr tab crashs when I try to listen to audio or to view any video. Here are crash report numbers:

Love some solutions thanks.

My browser just updated to version 100.0 and now there's a big white block at the top that blocks access to tabs and the Minimize/Maximize/Close buttons at the top.

I found a few other articles going back to 2015 with this same issue and the only solution that helped a tiny bit was checking or unchecking the Title Bar box. Unchecking it helps a little bit as you can see in the attached screenshot.

The top of the image is with the Title Bar box checked, the bottom of the image is with that box unchecked.

Any idea how to resolve this?
