@moderetstudios said in History panel causing a memory leak?:
No idea what is causing it, but sometimes when starting the browser an "Extension: History Panel" task would keep taking up memory until it freezes and crashes Opera. You can just end the task and move on with everything working fine but it's incredibly annoying to do every time it happens.
Same problem here. Extension: History Panel consuming 6GB of memory.
As a onehundredeyed, I disabled the history on side panel and works.
Opera, please fix it.
