@leocg yea but i didnt open it today at all,iu think the last time was 4 days ago.It doesnt open on startup.

I have been using opera for years and this is the first time this happened,right now its using 8gb with 15 tabs and every tab is using around 500mb,i can restart it and it starts normal and keeps slowly going up until it reaches 14gb!!i closed all suspect tabs and nothing happened,even with just youtube it happens,i disabled all extensions.
