Gmail: Multi-select & Progress Bars with Flashblock

A while ago Gmail introduced the nice feature of being able to multi-select attachments and to view their upload progress with progress bars. But, if you are using the Flashblock addon with Firefox this feature is not available, and Gmail will show you the traditional attachment option.

To be able to use the Gmail goodness, add mail.google.com to the Whitelist of Flashblock. You can do this in the Flashblock Options.
