I have been using the same web browser, in terms of ideology, codebase and heritage, since the release of NCSA Mosaic.
That was 32 years ago. And holy f**ck, that dates me.
Sure, I dabbled around with others. There was the original Opera, back when Netscape cratered and the only other real option was IE. Opera’s tab behaviours made me install Tab Mix Plus for FF, and I still find that extension to be the second-most critically important extension FF has, right after UBlock Origin.
And lately I took a shine to Vivaldi, but I have been weaning myself off of it once I realized that the Manifest v2 shutdown was unavoidable for it as well.
And the only reason why I even have Chromium is as a sandbox for any Google services I access and as a “naked” web browser for those websites who implement malware and spyware in the name of “website security”. Which, of course, also means a majority of websites that are “protected” by CloudFlare’s incredibly hostile anti-user practices.
And of course, I also run forks, such as Librewolf and others, also with the appropriate anti-malware and anti-spyware add-ins. It can be useful having multiple web browsers up at once.
But my main will always be Firefox.
