Using Flock was kind of a long shot. Flock is based on Gecko, like Firefox, which has given me a lot of problems. Flock served me well at first, but then starting gobbling up RAM. So, I’m pretty sure I’ve narrowed it down, for me, to XUL and extensions.
I’m not sure exactly what’s to blame for the specific problems I have: other programs on the computer? a single bad extension? I don’t know, but whatever it was, it was present in FF1.5, FF2, and Flock. And each had their own set of extensions installed. It’s not a core Gecko problem, because, as I showed before, Camino doesn’t have the same problem.
I don’t require THAT much from a computer: mainly, it has to be able to sustain my browser requirements. And those are tough, because I expect to be able to open 10-15 tabs and still have the browser function without (a) eating up greater than 200MB of RAM, (2) eating up > 10% of the CPU for more than a few seconds, and (third) locking up the browser or worse, the entire system. Enough use of Gmail, Flickr, or other AJAX apps and my Windows Gecko/XUL browsers toast themselves and everything around them. So I’m giving Opera a go.
The only crappy thing is that there’s no way to import form cookies, form history, cookie block list, ad-block filters, or history. And that sucks, because it’s going to take me a long time to rebuild that.
