Shortcut icons (4 rows of them) have disappeared from my Firefox home tab. After a Firefox update, they were gone. Just white boxes. I tried to re-enter shortcut information, but the box always goes back to white and empty. I tried a System Restore. That didn't work either. I depend on these shortcuts for my work and bill paying. Please, someone help me! Thanks!

Please help, I just screwed up so bad I accidentally pressed the red "close" button on Firefox on my Mac instead of the yellow "minimise" button and lost a bunch of tabs I need (they were from a while back so not in history)

There is no option to "restore previous session" or "reopen tabs" is there any way whatsoever to recover my lost tabs I am freaking out big time there was some really important stuff in there that I hadn't bookmarked yet like an absolute IDIOT!!! My session had stayed active through computer being shut down and restarted and Firefox updates but pressing the red "close" button has seemingly nuked it. Is there a way to go into folders and find the tabs? Anything please help :(

Any help appreciated, I'm desperate.

I just reinstalled my operative system, and with that my Firefox settings got reset. I know there is an entry in about:config to prevent ads from opening new tabs and pop ups without authorization, even from legit websites like the login pop-up windows when doing a sign in in Google, in those cases to allow the windows it's needed to click on the lock icon next to the URL bar and allow it from there. The problem is that I don't remember the name of that setting and I have spend an hour looking for it on Google.

Apologies if this is a bit limited, during typing it I ran into the issue I'm about to describe which navigated me away from this page and lost all the progress of my post as I was wrapping up :')

The issue I'm having right now is Firefox forcibly opening pages it thinks are a new site in new tabs, despite the site itself not requesting new tabs or windows. Specifically this is happening with sites between different "iterations" of itself while still being the same and having fully integrated layouts and UI.

For example: Most pages on the site have an update "https://www1" prefix, but some pages have the old "https://" only. Firefox keeps opening new tabs when navigating between these different pages despite them being the same website. I know the pages themselves are not sending new tab requests because this doesn't happen in Chrome.

So far, my "solution" has been to go through about:config to adjust the browser.link.open_newwindow value to 1 instead of 3, which forces all links to stay within the same window. This unfortunately causes a whole host of other issues though.

Because its an override, it also means any links opened from an external program (like discord) forcibly open in the last active tab, navigating away from the page. This is obnoxious and annoying in and of itself because it means to save the tabs I already have open I need to manually open a new tab in FF before clicking any link, which I never remember to do. (Goodbye post progress (': )

If that weren't bad enough, when trying to hit the back button to get to the previous page FF ends up in some sort of weird redirection loop "between" pages, where the last page will disappear but FF won't navigate to the link it was trying to open either, so its just a blank infinitely loading page with the URL of the link that was opened. The only way to stop this from happening is to navigate back 2 pages, losing the current page, before it starts the redirect loop. If the loop starts before this happens, the tab locks up and needs to be hard-refreshed with f5 or completely closed due to the weird lag it causes.

Literally all I want Firefox to do here is not assume a new tab needs to be opened just because the URL "seems" different to it. Is there ANY way to get this behavior?

Dear Mozilla/Firefox,

I've been using Firefox over the last couple of months/years but I just can't get the restore recently closed tab shortcut (CTRL+SHIFT+T) to work on my windows PC.

Here's a (Loom) recording of me showing that Firefox does correctly track the history of closed tabs and that I can click on them to restore but the shortcut (which is also mentioned as CTRL+SHIFT+T) just won't work: https://www.loom.com/share/7048894683654dccb4926aa4dd09e6a6

What I've tried so far: - Check if the history is actively collected - No I'm not using private browsing - I've read another support thread to check "about:config" and in there check that "browser.sessionstore.max_tabs_undo" is set (in my case it's the default 25) - Disabling all extensions (which I don't think are any suspicious or weird ones but disabled just to check - see attached image) - Resetting Firefox through the windows uninstaller - Fully uninstalling (using Revo Uninstaller with advanced check) and reinstalling Firefox

Please help me because I'm about to quit Firefox for such often used feature just not working...

P.S. it's working perfectly on my Macbook and I'm running the latest 96.0.1 64bit version

Hi

I had two Firefox windows open. One with 100+ tabs and the other with 1 tab. I closed the Firefox with 100 tabs, and then closed the one with 1 tab, without thinking. I then realised that I should have closed them in the opposite order, because I want the 100 tabs to get restored.

I opened Firefox again and was dismayed to see just the single tab get restored. I did some searching and backed up the "sessionstore-backups" folder.

I then tried to close Firefox and replace sessionstore.jsonlz4 with previous.jsonlz4 from the backed up "sessionstore-backups" folder. This did not work, as when I opened Firefox I still only got the 1 tab back and "recently closed windows" remains grayed out. Ctrl+Shift+N does nothing as well.

I used https://www.jeffersonscher.com/ffu/scrounger.html to inspect the backed up previous.jsonlz4 file and it shows

Open Windows Open Window 1 Tab 1 [...]

Closed Windows Closed Window 1 Tab 1 [...] [...] Tab 125 [...]

So the previous.jsonlz4 file does contain my mistakenly closed window but I can't get Firefox to restore the tabs!

Can anyone please help me get my tabs back? I'm on Firefox v96.0.1.

Hello, For no reason I can easily identify, the plus symbol labeled tab to open new tabs from the browser has disappeared. I can still easily use the right click of the mouse or the control t keyboard trick, but I would much prefer the convenience of the ever available and accessible plus tab option. Your help to restore this feature would be very much appreciated. I use a Dell pc laptop with Windows 365 and Firefox. Thank you, Milagra Tyler [email removed from public]

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!

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?

I have tried all of the about:config options to disable the auto-reload of the tabs. I have this working fine on my old machine macbook pro 2015 (same firefox version), but on the macbook pro 2019 i cannot get it to stop. Any help would be great as I need to switch between tabs during meetings and dont want them to keep relaoding

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!

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!

A couple days ago, late, I accidentally closed my main Firefox window before a little window that I'd forgotten was there - and all my 76 tabs disappeared. 1st thing yesterday I tried - 3bar / history / recently closed tabs - but the only thing in there was the one tab from the small window. Urg! I tried that and - 3bar / history / manage - where I could see my tabs but could only restore 1 at a time - not good for 76 tabs. I read a bunch of different questions about this same issue, and tried the suggestions, including some app called scrounge, but none of these restored my tabs. Help!!!!

Hello Support,

I'm dying inside right now. I had over 400 tabs open and launched a second instance of Firefox. After that I closed the first instance and restarted my computer. Now the 400 tabs are gone and even with "Restore session" I have no success. Is there any way to restore the tabs no matter how?

Warm greetings Ileies

hi

what code i need to put in userChrome.css to hide horizontal scroll bar in firefox but not the vertical one? also its any way to make skinnier the vertical scrollbar?

ty

Is there a way to always show the tab close button on the tabs? Or perhaps to show the button on hover of the tab? Chrome does this and I find that very helpful, in cases where I want to close a tab and do not want to re-open that page.

Some context: When you have many tabs open (I know, who does that?) and you want to close some of them, but do not want to select those tabs, currently you can right-click and scroll through the menu to the `Close Tab` option. This is slow and a bit clunky. The `Close Tab` menu option is buried in the bottom-middle of the list.

This issue is somewhat complicated by the fact that I use the excellent Auto-Tab Discard extension to discard/sleep tabs. (https://addons.mozilla.org/en-US/firefox/addon/auto-tab-discard/) So when a tab is discarded, and you click on it, the tab reloads. Which is silly when you just want to close it.

Anyone aware of a way to always show the close-tab button, or show on hover?

Thanks!

Hi, Imaging that, firefox is open, I clicked on a button that opening new window, how I can merge this 2 window in 1, in fact I wanna have that new window as a tab.

Google Chrome have this already.

Thanks !

I've just installed Firefox 113.0 and my tab bar is now above the toolbar and bookmarks bar. Up until 112, the tab bar was below the bookmarks bar. I have no changed anything in UserChrome and in fact that file is still dated 2020. I've searched but haven't found an explanation. Anyone know what changed or is this just a bug? Thanks

Any way to force all HTML files to open in a new tab rather than a new window? This really could be annoying when you are working on several local HTML files at once :(

Before if I wanted to refresh a page, I could click the refresh button or right click on the tab or page and select refresh.

And if I wanted to refresh the page but also delete the back history (AKA hard refresh), I would use a shortcut command like Ctrl + F5 or Ctrl + Shift + R. I had actually created a new shortcut Alt + ` to do that. And it used to work. It would delete my back history.

But for a while now, it hasn't worked. The hard refresh just acts like a regular refresh.
