I use FF Nightly as my primary browser at work. Sometimes a site doesn't work and I'll try it in Chrome instead. 40% of the time, the site doesn't work there, either, so I try Internet Explorer. By the time I get this far, 75% of the time, it doesn't work there either and I decide that the website is broken. Note that some sites I always open in MSIE or Chrome due to prior experience. It is worth noting that aside from a few web-based developers' demos, my browsing on the work PC is notably undemanding: documentation, blogs, email, messaging, etc. Among the actual web applications I interact with, many require MSIE... (Intranet!) At home, I use FF stable on Linux and nothing works, ever. I don't have enough RAM or CPU power... I also use qupzilla, which performs well enough, but some rendering fails and I don't feel comfortable using it on wild URLs because ... well that's off topic.
