Firefox Community Forum

Two days ago I closed FF and went to bed. I opened it the next morning and lost about 20 tabs. Ever since then, every time I restart FF, I lose all tabs except for one default tab.

TLDR: 1. "restore previous session" is not available. 2. Toggling Settings/Home and Startup does nothing. 3. Update? My FF automatically updates. 4. "about:sessionrestore" finds nothing,

1. FF help said I could go into History and click "Restore Previous Session" but that option doesn't exist. All I can do is look at History and see lists for today, yesterday, last 7 days etc.

2. Another advisory suggested Settings, Home and Startup, select "Open previous windows and tabs". but it was already selected. So I switched it off, restarted FF and then switched it back on. I still lose all tabs every time I restart FF.

3. Another advisory suggested, checking for updates. My FF automatically updates.

4. I tried "about:sessionrestore" It returns with the heading: "Sorry. We’re having trouble getting your pages back." Restore session is greyed out and "View previous tabs" produces an empty list. I've tried it a few times now, identical result.

Thanks for any help. Cheers, Andrew

I had to restart my computer for updates so I clicked on my container and closed it thinking it was like closing a program and then re-opening it. Now it's gone and several hours research with it. Is there any way to restore a closed container?

Как сделать так чтобы при открытии ссылок с панели закладок они открывались в новой вкладке а не в той которой уже что то открыто,типо если у меня активная вкладка ютуб и я хочу открыть твич то при нажатии на твич закладку он откроет в вкладке ютуба тем самым ютуб пропадет и все пипец.В настройках не нашел чет насчет этого ничего,если это нельзя поменять то я ржу и удаляю этот браузер

My account login details were out of date; I was automatically logged out. After re-registering, the ‘new tab’ option has disappeared from the bookmarks bar. When I tap on a bookmark, the page I was previously viewing disappears. Very, very inconvenient!

I wish I could manage which colours to select from for tab groups (I'm not particularly fond of the current options). I also wish I could manage the number of colours (there are currently to few). And i struggle to find a suggestions box to slip my wishes into.

PS. I miss the old tab group shape (the tiny squares), maybe make that an option, as well?

I had multiple tab groups which I had chosen to save and close. These tab groups have now completely disappeared and I cannot find them. When I began using Tab Groups, I had checked and there was no information stating that unopened tab groups would be deleted. I want these groups back. If I had known Tab Groups would disappear, I would have saved my tabs into a folder. The only Tab Groups that show up now are under "Recent tab groups". If tab groups are going to be deleted after a set period of time, it should be stated clearly in the tab group settings. It would also be really useful to archive them into a bookmarked folder so people don't unexpectedly lose hours of research.

Hi All,

I had several tab groups. I open and save and close them every day. but since yesterdayI cant find them at all. If I create a new tab group it appears but those old tab groups not! I've tested troubleshooting mode but noting.  

Firefox 154.0 (aarch64), macOS 26.6.2.

There was something changed with the latest update 156.0.1 in regards to how new tabs open. I have been using the extension "Always right" for years as I wanted all my newly opened tabs and bookmarked websites to open right next to the one I am at, in order that I open them in. Had no issues until the recent update. So tabs and bookmarks.

To explain this better, lets start with tabs only. Scenario 1 - say the tab I am on is "youtube" and the tab right from it at this moment is "google" tab. So: youtube > google > rest of tabs. While on youtube, I click on 3 videos/links from that "youtube" tab to be opened as new tabs, in the order that I want to watch them, using the middle mouse button. It used to open them in order: youtube > 1st vid > 2nd > 3rd > google > rest. In other words, it pushed the "google" tab and opened the new video tabs in order that I clicked them in between the two. Scenario 2 - bookmarked toolbar links. They behave similar but slightly different since opening those instantly jumps to the tab, which is fine. If I use the middle mouse button to open amazon for example while I am on the "youtube" tab, it would do the same thing: youtube > amazon > google > rest, only it will instantly jump to amazon, but the important part is that amazon is next to the tab I was on (youtube in this case).

Now though, in scenario 1 with tabs, if I open 3 new video tabs from the "youtube" tab, the LATEST one is the one that ends up next to the first one, so youtube > 3rd video > 2nd > 1st > google > rest. In other words, ANY new tab is forced next to the current one, rather than in the order of opening like it was before.

Turning the extension off "fixes" scenario 1 and opens them in order again, but then opening a bookmarked website from your toolbar shoots you ALL THE WAY to the right. So scenario 2 is ruined. To extend on the previous example from scenario 2, if I have "youtube" and "google" is next to it, and I go to open amazon from my toolbar, it goes youtube > google > rest > amazon. With 3 tabs that might not be that big of an issue, but when you have 100 tabs and I am currently doing work on tab 1, your bookmarked link that you just opened with middle mouse button suddenly catapults you and opens as 101 instead of 2... I hope this is a bit clearer as to why it is a problem. You could have both scenarios work before with just this simple extension, but the update is now forcing me to choose between tabs opening properly in order as they should OR bookmark toolbar links opening next to the one I am on.

If there was some change to how tabs open in the latest update and the idea was to no longer need the extension, can we at least have the option to ALSO have any new websites opened from the bookmark toolbar open NEXT to our current one rather than at the very end?

I am using Firefox on Linux Ubuntu 26.04. I normally work with multiple tabs. Then I quit Firefox with all tabs open at the point of quitting. Some times on the rare occasion there can be a forced quit due to some issues. In my settings I have configured it not to open the previous tabs. In fact I want a blank page. But whenever I reopen Firefox, it opens those tabs and tries to reload which is annoying. Some of these pages take a long time to reload, and why would I want to look at tabs which I already have read. Or if it crashes due to some website on a tab why reopen something that crashed in the place ? Can you fix this. Thanks.

Recently my browser has not been saving my tabs once I close Firefox. Every time redo the tabs and then close the browser, the next time i open up Firefox, they all disappear. In the Home and Startup settings, the Open previous windows and tabs is checked. I still have the closed tab history but it still doesn't save the tabs after closing the browser down.

I have installed the firefox browser using a firefox installer version 18.5.0.0. However, when I try to switch to vertical tabs, they are not activating, even when I try to click the sidebar button. Attached are screenshots showing a horizontal tab view working, while the vertical tab view is not working. How can I resolve this?

I am stuck in full screen. I can get back to the tab menu by moving my mouse but I have arthritis in my hands and every extra movement makes it harder for me to use my computer, in addition to the flipping back and forth being incredibly annoying. I am going to have to use a different browser if I can't find a way to stop this. There must be an easy fix but I can't find anything in settings that helps.

Since the last update (I know that Firefox DE is a beta/semi-nightly release, I just want to know if this is my mistake or a bug), only my first firefox window has address bar, all the other windows don't. And when tabs are vertical, the rest of the windows don't even have a title bar. (This behavior doesn't apply to newly created windows) Also, non-primary windows also lose the capacity to resize the vertical tab bar. ¿Did I do something wrong or is this a bug?

Upgraded to Firefox V.155.0 (64bit). Using Windows 11. The old version when accessing my Bookmarks allowed the option with a right mouse click to open that bookmark with the option "Open in New Tab". That option has disappeared. How do I get it back?
