Last night or, early the following morning MST, the error was that was breaking the browser on 4.4.4 was addressed first seen in the beta version then, the standard channel release version. Many thanks to the Opera team and commentators of the forum that replied to this post.

I would try a reinstall first. And no, you will not lose any data. By the way, Opera doesn't offer personal support.

this happened overnight, next time i boot my pc i find out that the browser works fine for around 5 seconds and the completely freezes, tried reinstalling but wont work at all

@sgunhouse oh sorry my bad, yes it remembers my tabs by then, it's only the very first launch on windows startup that deletes my saved tabs

@samseb Not only you, some of other people also experience it. Anyway do you tried to clean install the opera mini? Maybe it fix the problem, on the other thing, opening private tabs not working for now, I don't know why, it just crash after changging to private tabs on anrdoid pie
