Opera crashes from a lot of things (from my experience, it's an unstable pile of crap, at least the linux version), it's not necessarily lqt's fault. Then again, sometimes you can't see your newly posted comment, maybe that's related. Oh btw, https://bugzilla.wikimedia.org/enter_bug.cgi?product=MediaWiki%20extensions and select LiquidThreads from the list
Opera isn't that unstable, it just doesn't like things that are a little experimental. Often websites prefer to ban that browser than, you know, check their site actually works... but anyway.
I can't seem to consistently find what is the problem. It might be if it's trying to automatically update and reload the thread. If I can figure out the exact issue, I'll report it properly. As you can probably tell, I'm not the sort of person to just say "it don't work gud" and assume tech support can fix it like magic. I've been on the receiving end of generic complaints enough to find that isn't going to help at all.
Well yeah, but a decent browser shouldn't be crashing because some website has broken javascript.
Yeah, but sites shouldn't have piece-of-shit javascript.
Anyway, it's stopped it now so it might have been a background window being a dick.
