Thanks for the offer. And yes, in a couple of cases I've reported a URL via the Firefox made me sad feature.
I'm torn about doing more. On the one hand, of course I'd like to see the issues fixed and in principle I'm happy to help. As a software developer myself I understand the usefulness of detailed technical information and test cases.
On the other hand, every time I go near Bugzilla I seem to spend 15-30 minutes trying to figure it out, before sometimes getting to the stage of actually submitting a useful issue but more often just giving up. I'm sure it's great for people who use it regularly, but for an occasional contributor it's awful. And unfortunately the reality is that I can't justify spending a client's money like that every time I find a bug in a browser if I have four other browsers available to me within 10 seconds that can load the site just fine, and as selfish as it sounds, there's only so much income that I'm willing to give up by working on non-billable activities.
So again, thank you for the offer, but if you have any pull with Mozilla I would encourage you to spend it on either improving the reporting systems so we can all contribute more effectively in the future, or on improving the built-in diagnostics in Firefox so if I come across a site that does hang there is still a mechanism available to capture what was really going on internally at the time and report it back.
