If this goes on, I think I'll give Vivaldi a chance. While the MX5 is barely half of a browser, its installation RUINED my MX4 installation (fortunately I have everthing backed up), every time you open it, it LOGS YOU OUT OF MX4 session, so you have to relog into every single website you use daily.
Why was there a need to mess up with MX4, if you're working hard on MX5?!
