[Lilux-help] Fork of Firefox

Hello all, Like many other people, I'm starting to become fed up with Firefox: - crazy versioning scheme, which regularly breaks add-ons (such as HTML Validator) - bugs unfixed since almost 10 years - gratuitous and frivolous GUI changes (This is especially painful on a distribution such as Fedora, which seems to follow every Firefox version. On Kubuntu 10.04 it is bearable, as it sticks with 3.6) Of course, there's other browsers such as Opera, Midori or ... gasp ... Chrome. However, as one of the main reasons for my discontent is the breakage of addons, and as those other browsers don't have addons at all (or are incompatible with the many Firefox addons), switching to one of those wouldn't solve the problem... So, here's my question: does anybody know of a fork of Firefox/Mozilla from around the 3.x period which kept with sane version numbers while still fixing bugs? Or an entire different browser, but that can use Firefox add-ons? I know, there is seamonkey, but apparently it branched off in the 2.x days, which is a tad *too* old for me. Thanks for any ideas, Alain
