Since I run 64bit Ubuntu, I couldn’t use use Google Gears. Which was annoying. The Google Gears site says 64bit OSes are not supported. But it is open source. So I grabbed the source code, tweaked a few things here and there and I now have Google Gears up and running on my 64bit OS. It hasn’t crashed and burned yet, but I haven’t really tested it heavily yet, either (suggestions welcome). Anyway, here’s the XPI to install it. I’ll post the source soon. Or maybe just the diffs to the Google Gears list.
