I used to be able to move tabs right or left by drag and drop in the same browser window. Now, after updating to 35-Mac, i can't do that. How can I do that now?

Some Mac users have been having problems with Microsoft for Mac programs. Disable all of them for now.


Start Firefox in Safe Mode {web link} While you are in safe mode;

Type about:preferences#advanced<Enter> in the address bar.

Under Advanced, Select General. Look for and turn off Use Hardware Acceleration.

Poke around safe web sites. Are there any problems?

That works in safe mode, but when I reopen FF in regular mode, it's the same problem.

Thank you for your response -- It seems the "classic theme restorer" add-on is the problem. With that enabled I cannot move tabs. With it disabled I can. I've used that add-on for years without issue on Mac and PC. The PC is still fine, just the Mac is problematic since the FF update about a week ago.

So I guess that's the answer unless anyone knows of some other trick or setting to change so FF is able to have tabs below the address bar AND be able to move tabs left to right within the same browser window!

I also use Classic Theme but had no problems. Contact their support site.
