I've been using Firefox 3 from b5 version and I recently updated it to version rc1(Debian
distribution) and, with an extremely technical expression I have to say that it sucks really
bad IMO! The handling of memory is better now, but there are a lot of regressions from version
2. Except for the problem discussed here(which, by the way, I noticed too), there are other
problems like for example a big list of websites which are handled really badly, with
appearances and usability completely destroyed. I did a rapid search of the starting date of
Firefox 3 development, and I found that a first alpha release was ready on December 2006!
After so much time, I really don't know how cn they have still so many problems. All this
without considering the fact that webkit already completely passes acid test 3, while usually
firefox(gecko) scores around 60-65%.
