I'm having a problem changing Opera's css-stylesheet, I edited the file default.css
(.config/opera/Extensions/kccohkcpppjjkkjppopfnflnebibpida/1.44.4_0/css/themes/default.css) but it didn't have an effect. What I added to the .css file is multi-row_tabs.css from https://github.com/MrOtherGuy/firefox-csshacks/tree/master/chrome, lots of .css stylesheets there, you might want to check. I tried to do some searching on these forums and on Google and Duckduckgo but didn't find help for this. I'm running on Ubuntu 22.04.1 lts and Opera 92.0.4561.21. I also have the same problem with Firefox, couldn't get multiple tab rows in it either. Changed ...chrome/userChrome.css but it didn't have an effect either. Is there a switch in Opera that needs to be changed to get the stylesheet to work? I would be thankful if someone could help with this problem (and the Firefox problem maybe, tho it's an another competing browser, maybe I'll need to write to the Firefox forums too) :-).

@jhog I don't think you can change Opera's stylesheet.

@leocg What? You can change the stylesheet in any browser.
