I've noticed recently after system reboots that Firefox forgets the "Open previous windows and tabs" setting and restarts with only a blank tab. I've confirmed that this setting is ticked prior to the reboot. I know I can restore the session under History but why isn't Firefox remembering this setting and re-opening the windows & tabs like previously?

Running Firefox 135.0.1 and Mac Sequoia 15.3 (but has been happening in recent previous versions of both).

When the vertical tab bar is enabled, if there are no pinned tabs, when the mouse hovers over the vertical tab bar, the scrollbar will be in the exact position to display the active tab. However, if there are pinned tabs, when the mouse hovers over the vertical tab bar, the scrollbar will always be at the top.

Please give the option to have vertical tabs and sidebar functionality split into two seperate things. Much like with Edge and Vivaldi, we should be able to have vertical tabs on the left of the browser, with the sidebar on the right.

We should also be able to open any website in mobile view with the sidebar, again replicating the functionality of Edge and Vivaldi

Just started using Waterfox on MacBook.

When I use <Command><Tab> to switch back to the application, although the icon does appear on far-left on the display of application icons, indicating it is the foreground application, the application does not appear in front of the other applications as is usual MacBook behaviour.

I use Firefox for work and need to have a lot of tabs open, in a certain order, in a single window.

Frequently, when I click on a tab, Firefox moves that tab all the way to the right and I have to scroll over and move it back to its proper place. It also sometimes happens when I type in a text field on a tab and hit return. The tab "disappears" and I find it all the way to the right. It never used to do this in older versions of Firefox.

I don't think I'm doing something different than usual to trigger it. It just seems to be at random.

I really need to figure out how to stop Firefox from doing this. It's frustrating, disruptive, and slows down my work.

Platform: MacOS Ventura 13.7.5 and Firefox 137.0.2

Thank you in advance for any help you can give.

This feature has suddenly appeared and I absolutely detest it! I don't need it, don't like it, don't want it! I have searched everywhere on how to disable it. PLEASE tell me there is an option to do that.

Up until Firefox 116, Reopen Closed Tab (Ctrl+Shift+T) would reopen closed tabs, and Reopen Closed Window (Ctrl+Shift+N) would reopen closed windows. There was a clear bifurcation, so I could freely close windows and not worry about it polluting my tab history in another window.

The latest change has thrown out that advantage, and now Reopen Closed Tab reopens both tabs and windows, while Reopen Closed Window still just reopens windows. This makes the later essentially useless and the former much more difficult to use for me.

I assume this was done to just continue copying Chrome in all respects since that's how it handles it, but the changelog just vaguely states, "This change is in anticipation of upcoming changes to recently closed tabs."

Does anyone know if there's a setting to separate the two functions again?

Yesterday I had Picture-In-Picture (shortened into pip for next mentions) working on youtube, then after one day, PIP no longer works on any of the websites, including youtube. I tried disabling and enabling pip, entering troubleshoot mode, and none of them worked. Not reinstalling because it will be annoying to log in everywhere I've had account at.

Any solution?

Im using firefox since 2012 it was great until a couple month ago. The bug is when im browsing website like a payment page, when i switching between the apps and return to payment page, the firefox will refreshing the page automatically without asking any permission and payment will get fail error. This is awful

if i have for example 4 tabs open i will also have 4 windows that all share the same tabs. i have tried using "about:config" and inputting "browser.tabs.allowTabDetach" and setting it to false and it doesnt help. what can i do to get opening a new tab to stay on the same window

Hi,

Is this new feature? Once I click on link with middle mouse button, that tab is opened and switched to it. Previous firefox versions only opened tab and thats it. It is very frustrating. I want open multiple tabs and then view those tabs. Now I have to, suppose I have 5 links listed in webpage:

I middle mouse 1st link Then I have to return to my previous page I middle mouse 2nd link Then I have to return to my previous page I middle mouse 3rd link Then I have to return to my previous page I middle mouse 4th link Then I have to return to my previous page I middle mouse 5th link Then I have to return to my previous page

If it is new DEFAULT, then please make ant option to switch back in about:config, thanks!

I'm running version 118.02.2 (64-bit) of Firefox on Windows 12. I *always* have the 'Open previous windows and tabs' checked. Starting yesterday, Firefox opens with nothing other than a blank page. Luckily for me, this has happened in the past and I have a Bookmarks Menu folder with my default tabs saved. Even so, it's still frustrating.

So for starters I am fully aware of the "When you open a link, image or media in a new tab, switch to it immediately" setting, it is turned off.

What I want to do is be able to open new tabs from my bookmarks bar without immediately switching to them. Regardless of middle mouse click or right click and open new tab. Considering the mentioned setting is turned off I would assume that would solve the problem but it hasn't. It has however made it so when I'm browsing or looking through search engine results it doesn't open a new tab right away. But when I have a home/new tab open and am opening tabs from my bookmarks bar, it unfortunately switches to the new tab immediately. I have had this working on a previous install but am stumped as how to replicate.

Any help appreciated, thank you!

Recently the V-like icon/button appeared at the right-hand end of the top line of my Firefox windows. This Tab Search could be invaluable to some, but I have no need for it. If I start to get too many tabs I just use another window. However, I click on it constantly when I intend to minimize the window. I have been clicking on the - icon/button in EVERY WINDOWS APPLICATION since Windows began, and as it has ALWAYS been the LEFT-MOST item in the UPPER RIGHT CORNER I haven't had to think about it in decades. But now it isn't the left-most, that is now tab search.

Please, please, PLEASE provide a configuration option to remove Tab Search from the top line.

Thanks!

Hello,

I am desperately trying to recover lost tabs from Firefox Browser after 2 crashes, freezing and forced shutdowns. I need the tabs for my work, and as usually happens, this has occurred at a time when I'm running to meet a critical deadline.

I've tried going to history, but the "recently closed tabs" option was greyed out:-( I've tried searching for other solutions, but cannot fine any that fit my situation. I'm not an IT expert - I know my way around what I need to use (i.e. professional worker), so clear & simple explanation would be much appreciated.

Can I recover the lost tabs from backed up data or a previous system image? My system is Windows 7, and I'm currently running Firefox version 115.0.2. All suggestions welcome!

Thanking you in anticipation off prompt assistance, MLH

Hi, my Firefox on my iPhone was updated on the latest version (116.0), and upon opening it after the update, I realized all of my open tabs were completely gone! This includes the private browsing tabs, which typically persisted from opening to opening of Firefox. Every tab, both normal and private browsing, is now gone. How can I restore them? I've *never* had any issues with any prior Firefox iOS update before!

This is critical to me; thank you for your help in any way, whether that be it through my synced account (which also lost the open tabs, from what I can see) and/or anything else.

I need to shrink the size of my tabs, which remains constant no matter how many are open. If I have four open, I get the "+" for a new tab at the end of the tab bar. If there are five open, the tabs consume the entire width of the browser window and the "+" sign disappears. It is not found in the "customize toolbar" menu. I have tried restoring tool bar defaults and changing the uidensity to 1, but neither change shrinks the size of the tabs or gives me the "+" option.

What do I need to do to get back to the way it used to work?

After the latest update (117.0 64-bit) I now do not see the '+' sign in the tab bar. I have 40 tabs open (please, no negativity - it's always worked for me), but if I close all of the tabs it reappears. Re-open the original 42 tabs and it's gone again. Close them and it reappears, etc. Now for the fun bit: starting from scratch with a new window - the '+' is there, but open 20 more tabs and it goes.
