I uninstalled it after seeing how constantly it is updating. But I use Vivaldi, which is of the same family, and since I can install it as a portable mode and thus move it from PC to PC, as with Firefox portable. Yet main reason is that both can be hacked to enable multiple tab rows. But I still use Firefox EST 52 since classic extensions work on it. Each has their general specific purpose (but not gaming or porn), thanks be to God.
