It's been two days now since I installed Firefox 2.0 beta 1, so how's it behaving?

Quite well, I'd say. I've not had a crash yet, so the same instance that I ran after installing it is still running. It's not been closed at all in two days. Memory usage is high, at over 200Mb, but it drops to under 20Mb when minimised, then climbs steadily again. It still feels snappy, though, and doesn't seem to be holding other apps up the way 1.5 used to.

Looks quite decent, actually. Sounds like it’s going to be pay-for-ware when it’s finished, so it’ll have to be a good step up from the free Picasa to be worth it, but it does look good.

I probably won’t be trying it out myself - I’m still tempted with trying to make the jump to Linux soon, so I don’t want to set up a workflow for myself that involves any apps only available for Windows and Mac.

I’ve decided to go for it - I removed all extensions from Firefox, and upgraded to the Beta I mentioned yesterday. So far, so good. No crashes yet, and it’s running fast and smooth.

Memory use seems better, but it’s usually a day or two until the problems really show up, so I’ll reserve judgment. I’ve been pushing it pretty hard, though, and it’s only occasionally peaking over 100Mb.

There's a new beta of Firefox out. The earlier alpha release of this one was very good - I blogged about it, and kept using it for quite a while. I only switched back when an extension refused to work with the alpha.
