I dragged my feet for a long time before switching from chrome to firefox a year or two ago for that exact reason. When I actually did switch it was practically seamless, I haven’t run in to any website that has been problematic on firefox but not on chrome. The only thing i dislike is that i haven’t found a way to have a custom newtab-page but still be able to directly input text to the navbar, so i always have to do ctrl+t -> ctrl-a.
