For me, fennec is slower and less stable than Microb. In fact, I rarely exit fennec, it just quits or crashes. In addition where are the scroll bars? Scrolling is a pain, moreso than in microb, in fennec and minefield. Minefield has scroll bars, but it is weird and hard to use. When it is working, fennec does seem more compatible with some websites. Example: digg.com. Microb has a difficult time reading comments and instead opens up the comments on a new page. Fennec, if it doesn't crash before it gets there, will open up the comments on the same page.
