I enjoyed that brief Android Chrome experiment where the browser supported moving the address bar to the bottom. Now that feature has been made available on iOS, but remains AWOL on Android.
Firefox has its own set of problems on Android(mostly website compatibility) , but it is a much more pleasant experience not having to deal with ads at all on the phone.
None that I visit regularly, but occasionally there is one annoying link somewhere that refuses to display correctly in Firefox and forces me to use Chrome to see the content
(I still use FF as my primary browser on the phone.)
Recent Firefox Android releases reload a recently-visited website whenever I'm switching an app and go back to browser after a few seconds. Sometimes, it doesn't load. I've been using Firefox since 2021, and this was never happened to me before.
