If, like me, you've become fairly reliant on Google Gears, the browser plug-in from Google that allows sites to save data for offline access, the release of Firefox 3.5 is probably frustrating you. For some reason, Google isn't on the ball, even though the impending Firefox release was available for aeons in beta.

Luckily, for those of you that are brave (or dumb) enough to install an unofficial version of the Google Gears Firefox extension, you can get your Google Gears goodness going in Firefox 3.5 right now. Lifehacker points us to the unofficial Gears download locations for Windows & Linux, and Mac OS X (Intel only), but had only tested the Windows version at the time they posted about it. I can report that I'm dumb enough to install an unofficial Gears build, and it has so far worked flawlessly on my Mac. I use Gears regularly with Gmail, GCal, GReader, and WordPress, and all are working as expected.

Hopefully Google will hurry up and release an official Gears release for Firefox 3.5, but for now I've got a solution that works. Do you use Gears? If so, do you rely on it? What sites do you use it with?
