Zen Browser's priorities and ignored bugs have forced me to switch

[MoltenMonster]

I don't know how but just a few weeks ago the browser was perfectly fine and now its suddenly too unstable, none of the issues are on Firefox so I switched back to it.

• There are bugs with addons like Tab Session Manager that prevent them from restoring sessions properly.
  • Zen's built in session restoring has trouble restoring multiple windows.
• The bugs existed before Window Syncing was introduced, whose implementation is very unpolished (I'm not going to reiterate points others have made about it).
• Right now, the Restore Previous Session button is missing when I close Zen with a bunch of tabs, then reopen it. Normally (in Firefox) that button is always there, if its not an option then its greyed out rather than removed, so why did Zen remove it?!
  • While Zen recently introduced its own session management, it takes a lot more steps to copy session files in my profile folder than to just click the restore button, and it doesn't even save sessions consistently (or at least right after closing the browser).
• I tried installing previous versions but those had their own issues for some reason, maybe it's because I'm on NixOS, but I wouldn't switch to another distro just because of this.

I really don't like how the devs have decided to prioritize new window and session systems while bugs for time-tested systems from Firefox (which have worked reliably for several years for me) are yet to be fixed.

Overall, these are red flags, that Zen Browser is now in a bad state to daily drive; and it's a shame because I've grown to love having no top bars: the URL bar & all addons are on the side, & Zen is the only Firefox-based browser I know that has it. I really hope all of these could be fixed eventually.

What bugs does window sync have exactly?
