@bobstechsite I use Opera, but with major misgivings about using a closed-source browser.
If Debian update the firefox-esr in their repos to the newer version at some point, I'll switch back to Firefox. As it stands, the ancient version packaged up in stretch doesn't work on sites like er, Mastodon instances.
I know there are hacky ways to backport a newer version from sid but I have always subscribed to https://wiki.debian.org/DontBreakDebian
