The new Choose a Feed Reader dialog lets you configure Internet- or software-based feed readers. It also lets you select a default reader to which new feed subscriptions will be added.

Although it's a small feature, Firefox 2.0's new inline spell checker will be highly appreciated by bloggers, forum posters and anyone who types into Web-based text fields and sometimes makes typos and spelling mistakes. The feature works almost exactly like Microsoft Word's spell checking, and you can add a list of custom spellings for proper names and terms that aren't in dictionaries.

A new feature Mozilla calls bookmark microsummaries allows bookmark titles to display a bit of text that represents the current state of that specific Web page. So, when you bookmark a Web page that has a microsummary, you can choose to display the microsummary as the title of the bookmark. For example, a weather site might choose to display the current temperature and barometric pressure in its microsummary. Or you could write some code that would pull that information from the site. Either way, a "microsummary generator" would need to be created for that purpose.
