Edge has vertical tabs built in. Many other browsers can be made to have vertical tabs with plugins.

Edge is not free. I wouldn't seriously consider using a non-free application for something as essential as everyday web browsing.

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?

Given that the issue of Firefox being forced to restart primarily happens on Linux, I doubt Edge is an option for them. Though I have to concur that Edge has one of the most stable and smooth vertical tab implementations around, most of the plugin-based ones are more fully featured but much less reliable.

Edge has been released for Linux a while now... not that I know anyone who uses it, but it's available for those who need it.
