Isn't it Galeon 1.2 which went off the path?
Axel Beckert was ranting regarding how Galeon 1.3 sucks so badly he sticks to his Woody (Gnome 1.4 IIRC, Galeon 1.2) desktop. In one of the lines of his rebuttal/statement of what he wants from Galeon, he states:
I just strongly disagree with pure simplification being the right way in UI design.
This is the problem with Galeon: That it went far away from its original intention. Its original motto (which I discovered to be still in use) is The web. only the web… Well, I really enjoyed pre-1.2 versions of Galeon, but it just bloated, bloated, bloated until it was no longer usable for me. I too hate many aspects of Firefox, only it is the most usable browser I have seen… I still have to look at Kazehakase, but from the little that I can get from its page, it is not what I want. I want, just as you, something light, not over-featured, but tunable to my personal preferences. And while Firefox’s configuration is closer to the extra wheels for a bycicle you complain about in Galeon, I have been able to tune it quite a lot via extensions.
