Mozilla Prism
“Prism is an application that lets users split web applications out of their browser and run them directly on their desktop.” I’ve been waiting for something like Prism for a while, a means to pull out some of the long run tabs I use for webapps. It is often a PITA when your browse hangs because of some flaky site and you can’t access your other tabs. Prism still seems to use one thread: XULrunner. So it might not be a complete solution if you have several webapps and one causes problems for the others.
Plus flash doesn’t seem to be working at the moment. This might or might not be a good thing. Flash is one of the main causes of memory issues in Firefox. I have a couple sites using flash, the FX Oanda tracker for example, that I would like to split out of main Firefox browser.
Prism seems to handle http links intelligently. I’m guessing that links to external sites a passed-thru. At least with both Gmail and GReader it works as you would expect.
