The primary issue I keep running into is that when I consume media within the browser, say browsing reddit or watching movies, the cache seems to fill up quickly to around about 500mb, and the crap hits the fan. Webpages don't load, error messages show up, tabs stop responding and become unusable, videos become irretrievable or buffer continuously, it sucks. I have it set to clear my cache when I quit from the menu but that doesn't work. So every time the app starts having an aneurysm I go into settings, force quit, and clear the cache. Firefox is the only browser I use, but because of this I'm no longer committed to it, I will happily trade it for something better when it comes along. I expect nothing to change.
