This is infuriating to me as well. And the stupid Firefox restart dinosaur always comes up at the worst possible time. I would have switched to a new browser years ago, but Firefox seems to be the only one that supports vertical tabs.
I regularly have 2-4 Firefox windows with dozens of tabs in each and a "You need to restart" button press takes like 4-5 seconds max to close all windows and reload them all with all of my tabs as they were. The most I have to do is stick each instance on the right workspace.
Granted each tab will reload when opening it but if I'm updating my OS packages I'm probably not exactly "in the zone".
You can't really have usable vertical tabs in Chromium via plugins either, unless you're content with wasting a lot of horizontal space for an ugly sidebar and vertical space for uselessly duplicated tab bar.
Firefox is the only actual choice I'm aware about.
Why? Are you considering forking Firefox?
I don’t see how just using it does. So if you aren’t contributing to it you may as well use the browser with the best feature set for your use case.
lower market share =>
nobody testing against the free browser or fixing site breakage =>
quirks (bugs, underdefined specifications, nonstandard features) of other browsers becoming required for a functional Web =>
free browser is no longer a browser of the actual Web.I don’t see how that relates to market share, since regular users won’t do that.
