Firefox has been my browser of choice since 2005, whether on Windows, Linux or FreeBSD. On Linux and FreeBSD I use Lynx if I am in text mode. Regarding the memory thing, Firefox *does* seem to use less memory these days. Sometimes a while ago it'd take up to 1GB. Now whenever I check it's somewhere around 200-300MB, even if I had it running for a while. Also the extensions' breaking headache seems to be over now, at least with the extensions I use. The reason I use Firefox is useful extensions, and it was a disappointing having them break due to rapid release cycle.
