Hi, recently I just start to use Firefox...again. So, I notice Firefox already have the feature where user can register and login to sync their browser settings, but not all apparently. Please sync all settings once the user login to Firefox browser, like bookmarks, saved passwords, browsing history, browser appearances (light theme, dark theme, customized toolbar), so that when I use Firefox in another PC/laptop, I just need to login to my Firefox browser, and it will be appeared 100% exactly like the previous Firefox in my previous PC/laptop. Chrome does this, and I hope Firefox will too.
Synced Tabs GROUPS or Synced WORK SPACES
This is something that still blows my mind that Chrome has figured out and nailed down to a science, yet Firefox and Edge somehow can't. With Chrome, all I gotta do is sign in and everything is exactly how I left it: My toolbar layout is the same down to the placement of extensions and my added/removed search engines and their shortcuts are there too.
All Mozilla has to do is figure this out (and as an added bonus, sync modified flags as well!), and I'll switch back in a heartbeat.
