There have been long and continuing complaints about Firefox and what is described as “memory leaks.” Firefox developers have said Firefox does not have any. Or, at least, if there are any they aren’t show stopping problems.
Whether Firefox does or does not have memory leaks, I don’t know. But TechCrunch has an article on one of the many Firefox-based clones. The browser is called Flock, now at version 1.0.1 and it seems to use much less memory. It also has some features that social network folks might find helpful (see the Flock home page). But I decided to try it just as a browser.
It’s too early to say whether Flock is better than Firefox, and that is dependent on how you define better, but it is definitely different. Whether that is a GoodThing is also open to debate.
Still, it’s something new and shiny to play with and in limited use, hasn’t caused me any problems. YMMV. Insert disclaimer here.
