Obviously this won't work for people who need high-end graphics, but for people like me who don't it should be a solid temporary workaround.

I have a 2011 MBP with this problem. I do heavy compiles regularly so I hit this problem often. The problem probably isn't any third party software (I install almost nothing besides Xcode by default) - the problem seems to be with the discrete graphics card. If you are using the integrated graphics the problem won't happen. Turning off graphics switching won't stop this problem - if you turn that off the discrete card will always be used. There is no Apple-provided way to force integrated graphics all of the time. You have to use a program like "gfxCardStatus" to force integrated graphics. I haven't hit the problem since I did that.

I think each commit is weighted by the rating of the project you commit to. So no, that probably wouldn't get you very far.

A couple commits to Firefox, the #1 rated project, is probably worth many commits to a less highly rated project. I'll let you go to their site and figure out how they rate projects.

I wish this were funny, but it's not. Many, many sites (including lots of big name sites--Yahoo anyone?) look for "Firefox" and the Firefox version they want, rather than the Gecko version that has been available in the UA since before Firefox was called Firefox, and if your browser isn't called Firefox (and isn't Netscape, IE, or Safari), tough luck.

It really sucks for anyone trying to use (or build) a Gecko-based browser that's not Firefox.
