Firefox Stable (with ~50 extensions, userscripts & plugins) for daily browsing & development. Beats Chrome's slow tabs and lack of decent extensions api. Stable as always and only script freezes when another application decides to eat all my RAM and Pagefile. Firefox Nightly for web development and testing. Chrome Stable for second screen browsing and web development. It's only good feature, dev tools, is obsolete with Firebug and recent FF dev tools upgrades. (Love you Firefox WebGL Shader Editor!) Opera. Gone. Became featureless Chrome clone so worthless. RIP Presto. Internet Explorer because it is stuck in your OS like pre-installed Norton Virus. And to make me write twice as much CSS and Javascript to work around endless "quirks", dumb interpretations of new standards and plain ignoring standards. Steam browser for when I want a buggy, stripped down, extension-less browser with added malware ridden, spam, auto-playing, force-fed diarrhoea adverts experience.
