Firefox Community Forum

I have been using Firefox for 20 years, it always works perfectly until the 2 last update and these problems are driving me crazy!

Since the last 2 updates (137.0.1 (aarch64) on MacOS Sequoia 15.4), sometimes when I click on a tab, it just automatically moves all the way to the right...

How can I fix this?

My Firefox browser window has multiple tabs. I would like to be able to close them individually. The tabs do not have the 'x' symbol on them to be able to close them conventionally. I tried to right-click on the individual tabs, but the drop down menu does not have the option available to close the tab either. I tried rebooting the computer but when I open Firefox again, the same tabs are still there rather than opening up a fresh browser window with only the start tab window. I am using Windows 11 with this computer also. Help!!!

I use Firefox for work and need to have a lot of tabs open, in a certain order, in a single window.

Frequently, when I click on a tab, Firefox moves that tab all the way to the right and I have to scroll over and move it back to its proper place. It also sometimes happens when I type in a text field on a tab and hit return. The tab "disappears" and I find it all the way to the right. It never used to do this in older versions of Firefox.

I don't think I'm doing something different than usual to trigger it. It just seems to be at random.

I really need to figure out how to stop Firefox from doing this. It's frustrating, disruptive, and slows down my work.

Platform: MacOS Ventura 13.7.5 and Firefox 137.0.2

Thank you in advance for any help you can give.
