I think I love the tiny tab size, but indeed- on W11, when they become a certain tiny size they stop being functional tabs. At some point, they turn into volume-mute buttons. And at that point, I cant access the tab function at all!
@rajat2023 As you probably have already read in the bug submitting confirmation message, Opera doesn't reply to bug reports unless they need more info about the issue.
Command-control-F is simpler ... but doesn't seem to retain the last setting (and it's not clear that it should). Nothing useful evident in Opera settings.
@lot3rd1 You can do it the exact same way: Settings -> my flow -> activate my flow -> then just flick the lever. Its probably a new version so you have done it already but just in case you didn't.
It seems that this extension is outdated. I did install it once at the time, but now it's turned off and I can still (as @leocg writes) load extensions directly from the Chrome Web Store. On the overview it says if it is compatible with your device and when you install it you get a warning message that the extension is not from Opera addons. It will probably be the case (as it used to be) that Chrome extensions under Opera may not offer all features.
