11 tabs open. 1.7 GB memory used.
How ridiculous is this?
Sure, I can shut down Opera and wait 3-4 minutes (!) for the process to finally finish and restart it. Memory used will then be a few hundred MB. A few hours later it'll be right back up at 1.5+ GB. Opera slows down to an absolute crawl where it's almost unusable.
No matter what version I use (currently 12.15), I have always had this problem. And my PC is CLEAN... I'm actually a software engineer myself. How they do a job this bad is beyond me.
