Firefox 30
Is it just me or is anyone else finding FF30.0 utterly unusable? Since the "upgrade", I can open exactly one page. Any attempt to do anything on the page - click, scroll, anything at all - or open a second page results in the browser hanging and then (eventually) a full CTD.
OS Win7 32bit at work. At home on Win8.1.1 64bit and on debian it's fine.
