Firefox Support Forum

So I have an issue where I am unable to reorder or detach tabs after having detached one tab. When I start Firefox I am able to reorder my tabs as much as I want, but once I detach one tab both functionalities do not work anymore.

- Firefox version 126.0 on Kubuntu 24.04 - After restarting Firefox I am able to do it again once - After rebooting I am also able to do it again once - The same issue in private window - I have refreshed Firefox through Help -> More troubleshooting information - Disabled all my add-ons - Tried it in Troubleshoot mode

I cannot seem to find a real answer online. Does somebody here have a solution for me :-)?

Hi,

If I have an unloaded tab on right of the current tab and I close the current one, instead of going to the right tab, which is the unloaded one, it jumps to another tab which I'm not sure has what relation to it, it certainly is not the tab that opened it.

I removed every modified entry of "Browser.tab" in About:Config, installed "Select After Closing Tab", no result.

Thanks

If you close a tab that is next to one or more unloaded tabs, firefox jumps those and opens the next one that is loaded. Is there a way to disable this so upon closing it would open the right tab, whether loaded or not. I tried "Select After Closing" add-on, didn't fix it. Disabled Auto Unloading via about:config, same result.

Since the new update, when I select an autofill a new tab opens for the settings. I have closed it many times, double checked the settings and closed it, etc. but it still opens a new one every time I use the autofill feature... please advise.

I just tried the free Avast anti-track product. I ran a browser clean-up which included browser cache but NOT browser history. (they give you options on what to clear). Now I have lost the 50+ tabs I always open on startup. I have also lost all browser history older than 2 weeks. Avast can't help. Anyone know how I can recover my tabs?

Hi. Randomly, but very often, I cannot drag and drop move tabs. Other moving (p.e. "move to beginning") does work. After restart of Firefox, it works again - till it randomly does not.

Current Firefox (126.0) Kubuntu Installed via Snap

Sometimes drag functionality stops working. I can't grab a tab to move it to another position or to a new window. (Holding left click on the tab and moving the cursor does nothing). Also, re-merging the tab with another firefox window stops working. (Dragging a tab to a firefox window from another firefox window doesn't merge them. It does nothing) I can right click on the tab and select Move to move it to a new window but dragging stops working. I have to close Firefox and start it again (sometimes twice), then dragging starts working again. This happens multiple times a day. I am on Linux Mint and the version is 126.0 (64-bit). This problematic behavior has only recently began.

I use version 115.11.0esr (32-bit). I need help with the color of open tabs. How do open tabs can be all in one color and that is black or dark gray? I don't want all open tabs to be bright because it stitches me in the eye. Active tab can be any color but for all other open tabs I want them to be in the same dark color - black or dark gray. Is this possible and how can this be achieved? Thanks very much.

I can log into Firefox, but if I try to click on nay other websites, the URL comes up, but nothing loads. I try to refresh the page, but the refresh 'circle' is greyed out and doesn't work. Then it's as if my mouse pointer is broken; I can't click on anything. Everything works fine in EDGE and other browsers. This seems to have happened after the last Firefox update. I have cleared my cache and data, and refreshed Firefox. So far, no good.

Hello, I closed my browser, expecting it to save my current tabs as it usually does. When I reopened it, the tabs were gone. They were important for me, and some of them were pretty old so I can't find them in my history. I tried checking the "recently closed tabs" option, it didn't help. There was also no option to restore the previous session. Can you help me restore my lost tabs?

It seems firefox has changed the behavior of tabs. When I go to open a closed tab, I see a list of all the tabs that have been closed from every window. I want to restore the previous behavior where "recently closed tabs" only shows the tabs that were closed in the current window. I saw some about:config settings, but I'm not sure what they do and I don't want to end up losing the tab history all together.

Thanks

The plus sign in the tab bar has always been on the far right side. I reloaded Firefox yesterday and now the plus sign is directly after the tab. How do I get the plus sign back to where I like it?

I was having issues with my laptop so I decided to do a System Restore to a previous date. Once completed, I opened Firefox and tried to restore previous sessions, but none were found. I also noticed that the shortcuts were blank, possibly uninstalled. I clicked on shortcuts and nothing opened. I downloaded Firefox again and reinstalled, but now I cannot restore my previous sessions. I tried to restore going to History>Manage History>Import and Backup>Restore>Choose File and selecting previous.jsonlz4 and recovery.jsonlz4 file with a date from last month, but again nothing happens. I searched around for answers, but only came across instructions to compress jsonlz4 file and decompress using mozlz4 without any instructions on how to use it.

What else can I do?

My Firefox settings are configured to "Open previous windows and tabs" on Startup. This worked fine until this morning, when I lost all of the tabs in my session, including the pinned ones. The last time I closed Firefox, there was only one window open.

I have already tried these ideas to restore the tabs:

• CTRL+SHIFT+T: Does nothing
• CTRL+SHIFT+N: Does nothing
• Three bar menu -> History -> Recently closed tabs: The list is empty
• Three bar menu -> History -> Recently closed windows: The option is greyed out
• Three bar menu -> History -> Restore previous session: The option does not exist in the menu
• Open user profile folder and open sessionstore-backups folder: There are three files named "previous.jsonlz4", "recovery.baklz4" and "recovery.baklz4". They are each 2KB and contain only an empty tab with the URL "about:home". There are three additional files starting with "upgrade" but they are from too long ago, so they don't contain the tabs I require.

The contents of these tabs are vitally important for my work, so this is causing me significant stress. If anyone can suggest ways to recover my previous tab beyond the documented fixes, I would greatly appreciate it. Thank you so much to anyone who can help!
