After using Thunderbird as my mail client for a whlile, thunderbird isn't as useful as gmail web interface to me. But the search engine of mails is truly useful to me. I love to use the powerful search engine of thunderbird. Yesterday I read an article about setting gmail as default mail client. Then I thought using simply the gmail or webmail as email tool may be better than using by thunderbird. Today Ubuntu will release its latest stable version 10.10. There are new features in the upcoming version, including new designs of interface of netbook version and evolution. I don't think evolution mail client is useful to me. It's probably because I don't use email frequently. Nonetheless, I would tweak my system a little for switching thunderbird to gmail web interface. This is the link. And I have to modify my gnome indicator applet configuration. According to this, I modified the names of file and execution path. (thunderbird-mailto.desktop to firefox-mailto.desktop, exec path: Exec=firefox -remote "openurl(https://mail.google.com/mail?view=cm&tf=0&to=&fs=1,new-tab)")
updated: because I still can't figure out how to modify the gnome indicator applet configuration for "Compose New Message", I decide not to use the functionality. Delete the firefox-mailto.desktop file in /usr/share/applications/ and /usr/share/indicator/messages/ (By the way, the update is edited by firefox addon, Scribefire next. Good addon!) And I also found a useful notification application in Linux, called specto. Looks good! But I would try this application after upgrading to Ubuntu 10.10.
