Φόρουμ υποστήριξης - Firefox

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 :-)?

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.

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.

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?
