Interesting info about e10s, and i'm really looking forward to using FB3.
But i can't do that (and please don't force the upgrade) until FirePHP is updated to be compatible with the rapid changes that have been coming from FB & FF. It's long overdue. ;-)
First of all I really like the FB 3.0 but the fact that logging from the server, in this case php with firephp doesn't work makes it a bit unusable, I do a lot of AJAX development and seeing what is going on on the server is essential in my workflow.
Did some switching between FF and FF developeredition but that's not working either. Tried Chrome with Clockwork, it works awesome and it would be great to have such a feature baked in into FB.
Although I like Open-source, I rather pay for a stable environment where I can rely on the tools I'm comfortable with, the trouble with open source in this case is the fact that the developer isn't updating the plugin, he doesn't have time or interest in it anymore so it seems.
