I tend to have to use it at work. The reason I haven't shifted at work is a ridiculous one really - it's the way you can tear off tabs and move them to another screen - it doesn't tear the same way as Chrome. Like I say, ridiculous.

I've used this exact feature on firefox for years

How do you get it to tear off and show the whole window while you are moving it? I would love that, then I'd literally switch in no time flat.

Drag the tab away from the title bar and to a different screen, it should just birth a new window and live in that. You can also drag tabs from one window to another, or drag a window with only one tab to merge it with another window

from personal experience, it's the performance and bugs of firefox that keeps me away. for this reason i will not switch.

Firefox keeps improving. Since I switched back, I've noticed it has less bugs than Chrome had.

oh, for sure. it's just that at this point in time, on my macos firefox is simply inferior to macos chrome. fyi i'm a power user (tens/hundreds of tabs, lots of web development etc), so this might not apply to everybody.
