I downloaded the Better Gmail extension for Firefox recently. It has some very handy features. One I particularly like is being able to include an html signature in the message.
It also lets me add a link to Google reader in the sidebar and then lets me read feeds without having to navigate to another Google site. I think I'll give Google Reader a bit more attention now, at least to see if it outperforms Bloglines. Not that I'm unhappy with Bloglines, it's working well for me.
