Burnout426 made fix but it did not work for me
And i asked chat gpt to instead of fixing problems in existing extension
Create one with same functionality that will work in new opera
If you want icons and stuff just give this zip to chat gpt and tell it about classic tabs
Look into Burnout426 link for readme file to learn how to install both
I would 1st try Burnout426 extension and if his don't work for you then try this one
