Firefox Community Forum

Recently Mint upgraded my FF to v147 - possibly relevant, possibly not. There's no post mentioning anyone having this issue on the Mint forum though.

In my Settings, "Open previous windows and tabs" is definitely enabled, but it doesn't happen. I only get my homepage custom URLs.

I went into troubleshooting mode and FF then behaves.

So I figured the issue must be with an extension - but I disabled all my extensions, and it doesn't help. Only going full troubleshooting mode fixes it.

What do I do next please?

When I start Firefox on Windows it does not open all the Windows it had last time even though that option is selected in settings. It seems random on which Windows open.

Then I start one Window at a time and restore my tabs from bookmarks. Once I have done that I have all the Windows in the order I want, with the tabs I want.

Then for no apparent reason some of the Windows disappear and/or the Windows change order. This is very frustrating.

How do I get Firefox to always open the Windows in the correct order and keep them displayed in that order?

On my MacBook Pro laptop, when I minimize a Firefox tab I cannot access other apps on the laptop. I can see them, but they do not respond to a click on them until I unminimize a Firefox tab.

My selected topic "settings" actually does not really describe my tabs problem. Even though I followed instructions for entering "about:unloads" the expected webpage did not appear. All I got was the same instructions and not a page that included the table and its unload button that was said to be above it. When I select the New Page tab and right click and then select three tabs, the right-click menu only shows the option to "close three tabs." There is not an option to unload three tabs. Yikes! And when I select one tab and click on the one option to unload one tab, the selected tab does not unload. The tab does not unload. The tab does not unload. It is still there. (???) This is very frustrating! I can only close tabs. So far I can only temporarily close them. Could the problem be that I am still using Windows 10? Please advise. Thanks for reading about my problem of not being able to unload my unwanted tabs.

Hello,

I have my browser startup settings set to 'open previous windows and tabs' However, every time I start up firefox, it is on the default new window screen rather than my previous tabs. This feels frustrating as I have to reopen the tabs every time.

Would it be possible to fix this?

Thank you.

Hello! Recently i migrate to Windows 11 25H2 and when i use sleep mode and open browser after waking PC up - browser opens without all previously opened tabs and i need always use Ctrl+Shift+T to restore them. Sure, checkbox to "restore all previous tabs" are on. BUT! If i reboot PC (via shutdown or Shift+Reboot) and launch browser - all previously opened tabs are present. Found this issue 2-3 weeks ago and still cannot fix it.

I made a tab group i saved it and closed it save memory, but i don't know how to find it to restore it I assumed after saving it there would be a list in my menu of saed tab groups for latter restore but i see nothing in the menu....

i normally have over 200 tabs open, but i've been getting lag and memory issue with my pc so I thought i'd uses this feature to close and organize some of my tabs....but i can't figure out were the menu that lists my saved tab groups...

When I open firefox it loads 14 different tabs, if you view it from the task manager in Windows. It only shows one tab, when homepage is opened initially but clearly it's loading more in the background.

I have run the troubleshoot function as well as restart app (within fierfox settings)

I have also emptied the cache

I have pinned tab, but reaching them is inconvenient. I have to wait until the "List al tabs" menu appears. Is there such a thing as having the pinned tabs always visible at the beginning of the tab bar?

I also like this new sidebar pop out. Is there any way to place selected tabs there? There is this 'Tabs form other devices" options. Since that is the case, I don't understand the point of not allowing us to put tabs ion that sidebar from anywhere we like.

Hello, I periodically check to see if there is a way to stop dynamic tab resizing without having to edit the registry. I have tried several methods involving tab size in settings and nothing has worked to stop the dynamic resizing. Any new ideas out there?

Hello and happy new year Mozilla !

I just saw that there isn't 'list tabs' (V) in the vertical layout. Did you have any idea of how to rectify this small oversight ? Thank for this browser. <3

Bye bye

This has been infuriating me for a few weeks now, I accidentally close tabs all the time when using Firefox and I normally right click the top and click the "Reopen closed tab option. However since this change, I have constantly been miss clicking on the "Turn On Vertical Tabs" options which is incredibly infuriating because It adds 3 more clicks to just reopening a tab. This "Feature" cannot be turned off no matter how hard I try and I am very close to switching to another browser due to this.

Using Firefox 145.0 (64-bit), "Firefox is up to date" on PC with Windows 11 Pro.

I was so pleased when Firefox's Group Tabs arrived. I often have about 12 tabs open to do Railway research. So I thought, Group Tab, great idea. Save a group of tabs as one tab. Instead of creating a Bookmark Folder and each time opening all bookmarks from said folder, what better way to do than opening one tab. Or so I thought. I also created a "SHIP" tab for my hobby in the shipping industry, so I could have two group tabs that could be collapsed making the tab bar tidier. I saved an closed each group tab then closed down my PC. Next on restarting, Firefox starts up automatically as chosen by me. Both RAIL & SHIP tabs reappeared without me doing anything. Great! However yesterday, I inadvertently opened another Firefox window, forgot it was opened. So when I shut down my PC, I closed the Firefox browser and then discovered the over Firefox window I had opened. Closed it shut down my computer. Of course when I opened my PC today, Firefox started automatically, but with the tab that I had open in the last Firefox window. No problem I thought, I will just open the saved Group Tabs. It was a problem, where are the Group Tabs saved? Could I find the location? NO! I looked in Bookmarks, all the various History lists, even the down arrow to list all tabs. Nothing, the Group Tabs are none existent. I have checked on the "about:config" section for Group Tabs and everything is enabled "true". So where are the Group Tabs saved? I have been with Firefox for around 14 years, often citing it as the best browser. But over the last five years I find myself using Chrome more and more. Chrome has Group Tabs which do not not need the users to save them, they are saved automatically, and are easily found on opening the Chrome browser. Why doesn't Firefox have this?

I have set the minimum size of tabs to 50 in about:config, but I still usually have more pinned and regular tabs than will fit, and it goes into the overflow arrows. Is there an add-on or configuration where I can have the tab overflow as a drop-down?

TIA for any help you can give me.

Can anyone explain to me why Firefox apparently can't seem to maintain its open tabs? In a world where every other browser appears to retain active tabs between sessions, it seems Firefox will permanently lose all of them if you so much as blow on it, i.e., inadvertently close a tabless window, effectively overwriting any previous window with the open tabs. At the very least, other browsers allow users to recover any lost tabs, and even entire windows of tabs, with little effort. The fact that this hasn't been addressed is perplexing.

All of my tabs at the top of the Firefox window have vanished. There's a list of websites at the left side to choose -- but I am not able to open more than one window. I want to restore all of my tabs!

For a week my pinned tabs are lost every time I open Firefox. I have checked my settings, they were the same as always. I have de-selected them, closed and re-opened firefox, selected them again, closed and re-opened again, pinned my tabs again. Then closed and re-opened firefox and still they are not there. I have done this multiple time with the same results. This seems to have started after the last update.
