Now I'm using Chrome and everything seems to be nice. So far I can only complain on amount of processes it runs and amount of memory it takes (in total).
I have no idea why it's so messy. Hmm.. It seems that it's not the only one software, that does that. *looks at discord* ( ͡ °_ ͡° )
Chrome spawns a new process for every tab you have open, and for each Add-on running in the background. You can see what its doing by right clicking an empty space on the tab bar and clicking Task Manager (For chrome's specific one)
Firefox however has one process for all tabs, and Discord does.. something similar, splits them somehow, haven't worked that one out.
I haven't had any issues on the site lately but I've only browsed a small amount, and on either my phone (Chrome on Android) or my netbook (Midori on Linux), everything has been perrrrfectly fine.
Honestly Opera feels like a Chrome whose appearence has been changed a bit but yeah, it's good
It wasn't before, but iirc Opera is now just Chromium (The open-source browser Chrome is based off, so basically Chrome) with a fancy skin and a few unique features. So in a way you're actually correct.
