Firefox gemenskapsforum

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?

I have lost my tabs after the recent update. They used to show all tab groups in toolbar icon as mentioned here (https://support.mozilla.org/en-US/kb/tab-groups) in manage tabs section. Only the groups that were open are retained, the groups which were closed are lost. They contained important tabs which I haven't bookmarked. I didn't see any policy of removal of inactive tab groups after certain time, any help would be really appreciated. I use the desktop app on Linux.

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.

In the pass while on a tab inside a group[1], whenever I 'open link in new tab' it keeps the group closed, but now it forcefully opens the group. Is there setting I can press to stop this.

Due to a drive failure I had to do a fresh Windows install. Since then my Firefox has not been loading tab favicons for the tabs from my previous session when I launch it. They do not display until I click on each individual tab. I have tried poking around in about:config and turned off several lazy loading functions but nothing has fixed it. browser.sessionstore.restore_tabs_lazily and browser.sessionstore.restore_on_demand are both false with no effect on this behavior.

Any ideas for how to fix this?

I have four identity containers (container tabs) that I need to open simultaneously all the time, but doing it manually one-by-one is tedious. I want to create a one-click launcher via the command line that starts all four container tabs at once, yet I couldn’t find any switch for it in the help page I checked: https://wiki.mozilla.org/Firefox/CommandLineOptions. My Firefox version: Firefox Nightly 149.0a1. My Operating System is Windows 11

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...

I find that when I reopen Firefox, many of the tabs in a group are duplicated, appearing both inside and out of the tab group. Is there a fix for this or something I can do? I'm on Firefox 147, on Windows 11. Thanks.

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 set up a new Group with 14 tabs. From my main page I open the Group in a new window, peruse the 14 tabs, then save and close the Group. If I re-open the Group in a new window during he same main session, the Group opens in a new window perfectly. If I shut down the computer and re-open my main page a day later, AND then open the Group in a new window, one of the Group tabs opens in the main window and 13 open in the Group window. I then re-add the open tab from the main window to the open Group window. Again, I get the same behavior with all 14 tabs opening in the Group window during the same session, but only 13 in the Group window if I shut sown the computer and re-open a day later. Anyone have a solution??

Thank you!

Hi, Just looking into using Tab Groups. I can create a group, add or delete tabs from it, and the Save and Close Group. This Group is then visible to re-open from the List All Tabs option.

That is Great.

However, if I close Firefox, and re-open it, then that tab group has disappeared from the List All Tabs option.

Is that correct, or am I missing a setting somewhere ?

Despite having the setting "Ctrl+Tab cycles through tabs in recently used order" selected, CTRL-Tab has suddenly stopped cycling tabs in the most recently used order. Firefox behaves as if the setting is disabled. This is the third time I've experienced this issue in the past year, and every time the only solution that worked was to create a new profile. It is exhausting to get a new profile back to exactly how the old profile was, and it's something I shouldn't have to do.

Scenario: I am on Windows 11 (though I think this has also happened to me on Windows 10), currently using version 146.0.1 (though this has happened on previous versions). CTRL-Tab cycles in the most recently used order just fine for several months, then it suddenly doesn't—this happens in the middle of an active session, i.e., not after a restart of the browser nor the computer itself. I have four add-ons, none of which control tab cycling, nor have I added/removed any add-ons nor changed any of their settings since their initial installation many months ago.

What I've tried:

• Disabling/re-enabling the setting (even though it is already checked)
• Disabling/re-enabling the config browser.ctrlTab.sortByRecentlyUsed
• Restarting Firefox normally
• Restarting with add-ons disabled—note that the issue persists even with add-ons disabled
• Disabling the setting, then restarting Firefox, then re-enabling the setting
• Restarting the computer

It's the same thing described in this Reddit thread. What else can I try?
