Yes. Because the UI and UX of a tool that you use everyday matters. The average user will hold ease of use over privacy 9 times out of 10. In my case though I wasn’t able to use FF for a while due to the lack of debugger support for a project I was working on. Now it comes down to me having to work on multiple projects at once so tab groups and organization are key. Now don’t get me wrong, once Chrome totally kills adblockers I’ll drop Chromium browsers like a bad habit, but the point still stand though, FF could use some UI improvements.
Id argue on mobile for instance, firefox is easier to use. One of the LARGEST differences between chrome and firefox from a UI standpoint is bottom search/site box over top one, especially for larger phones.
This of course doesnt consider anything related to addons yet.
