Replacing Firefox with Epiphany?

> Exactly - although if I was developing Gobuntu I think it would be more 
sensible to update Firefox to use free icons than get rid of it...

Maybe they just wanted a browser that is / can be properly integrated to 
the  Desktop.

(At logout there's dialog saying that Firefox doesn't support session  
management and at re-login & Firefox restart Firefox asks whether I want 
to restore its session because it thinks it crashed. Mozilla Bugzilla bug 
about supporting the standard session management is 6 years(!) old.  The X 
session management isn't exactly new technology either...  As Firefox 
already support session management internally, it shouldn't be a large job 
to make it integrated with desktop too, like every other application in 
Gnome, KDE etc.  And this is not the only issue in Firefox.)
