I'm actively running or testing #Firefox or multiple Firefox-based browsers. I'm getting sick and goddamned tired of realizing that one of those browsers decided to change my settings, especially keeping my tabs when I shut down the browser, and now I lost everything and have to hope I have it in history or lose where I was.
I want to be able to send tabs to different browsers on different devices, but #Mozilla is making a use case to log out of their sync account.
This HAS to stop. Period.
