Firefox UI renders Firefox unusable when "too many" tabs are opened

Since firefox ~94-95 firefox became hardly usable because of their new tab handling and does this:


any tricks how to fix this besides closing half of the tabs or moving them to separate window?

Set browser.tabs.tabMinWidth to 100 in about:config

sadly doesn’t seem to help. at some point when you add more tabs it still starts doing this.

Then set it to 200 and relaunch firefox.
