I’m overall pretty happy about the release of Firefox 3, but am I the only one who’s seeing sporadic issues on Macs? On my iMac (2.1 GHz PowerPC G5), it’s painfully slow, so slow that I’ve started using Safari as my primary web browser. And on my MacBook Pro (Intel Core 2 Duo), I’ve had at least a dozen instances in the past three or four days where, during the loading of a tab, I get the spinning rainbow beachball of death and have to force-quit the app.

Ugh.

For those who are all excited about Twitabit, the service that promises to queue up Twitter postings if the service is down, consider these two factlets:

1. Twitabit asks you to type in your Twitter password — as in, you’re on a page on twitabit.com and asked to type in your password to another site entirely;
2. Twitabit appears to have not one word of a privacy policy, or any other text that’ll help you understand why on Earth you should trust them with your password to another site.

Ummmm, no thanks. No thanks at all.
