[OU] Opera 9.60 / from thunderbird & firefox

[Richard]

Thinking of switching to Opera, but first, have a few question or needs,
before I would switch.

#1. Can Opera Mail import Thunderbird Mailboxes
#2. Can Opera Mail 817,000 emails.
#3. Is there a delicious plug-in extension (I use this allot in firefox)
#4. Is there a scrapbook plug-in extension (I use this allot in firefox)
--

That would be my minimum to get me to switch...

Thanks!
Rich
