Well, after a bunch of changes, 2 or 3 invites, extension and greasemonkey script installations, re-installations, I have given up. No I will not use Firefox 2, no I don't want anymore invites. I am using Firefox 3 now.
Never have I seen a more complicated software installation process.
After receiving another invite via e-mail I did a fresh install of the extension. It did not work. Then I tried to install the greasemonkey script and my browser froze. When I restarted and navigated to Google Reader all I got was the orange drop-down menu. It does nothing. I chose individual feeds and all that. Nothing.
To be honest, this takes an extraordinary amount of patience even to try to tolerate this bugginess. This should have been labeled as Pre-Alpha, use at your own risk, not ready for primetime.
I tried, very hard to get this to work and it consumed a lot of my time. I would recommend you just prominently warn Firefox 3 users that an installation this product is not to be attempted.
I will check back soon to see if any progress has been made. AideRSS looks like a very nice usefull tool. I just don't have the patience or time to fiddle with this anymore.
Good luck and look forward to using this soon. Thanks.
