And yet, chrome doesnt feel slow to me. The difference isn't nearly as stark as it once was between the two. FF lost because
they lost the plot.
If I were a tab hoarder (I.e. didn't know how to use bookmarks) or thought that Mozilla were any more trustworthy than Google (why is it that the for profit puts out FF but the not-for-profit collects donations that go to anything but?) then I would switch.
I'm waiting to see how manifest v3 shakes out- Chromes plan is still better than safari has been (she admittedly low bar) but until thr browsing experience is affected, I have no problem sticking with chrome / chromium.
