I’d like to have a firefox memory monitor, like the unix program top. It would show a list of all of the web pages currently open in different tabs and windows and how much of my system resources they’re each using. At the last, I’d like to know how much memory and CPU each is using, but other things like network connections, bandwidth, etc would be nice to know as well.
Obviously, I’m not the first person to notice firefox’s memory issues. There was a post a while ago on techcrunch talking about the forthcoming release of firefox 3 and comparing its memory usage to flock. There’s also a feature request on bugzilla requesting an about:memory page in mozilla, which kind of addresses this issue, but only in a very developer-centric way.
