I would like to use Thunderbird as a replacement for Mail/Addressbook in Lion because I dislike the latter apps so much however there appears to be no way to sync my contacts with Thunderbird.

Sure I can import them but if I work with them in Thunderbird there is no apparent way to have the changes sync back to Address Book; rendering sync with my iPhone useless.

After all these years and the success of the iPhone one would think that Thunderbird and Lightening for that matter would sync seamlessly with Apple's info apps. This is the sole reason I don't use this.

If I'm being dumb and not seeing something obvious I'd appreciate some feedback. Thanks.

Now also seeing message corruption and inability to open emails at all. Looks like something is seriously wrong with TB12b2

My version of Eudora OSE has somehow developed a corruption and I can no longer access any of my emails. Does anybody think that having Thunderbird import the Eudore OSE data that I could then get to my emails?

I tried leaving messages at Eudora OSE's blog but I have received no responses. Any help would be greatly appreciated.

I like the tabs on top and they look better. But several of my complaints about the client still exist:

- The wide view needs an overhaul to provide more data in less space, like Mail.app, Postbox, Outlook, etc.
- If messages are sorted newest on top, deleting the current message moves you down to older message rather then up to the newer message.
- Growl still isn't working for me

The 11.0 update seems rather minimal. If you've had issues with Thunderbird in the past, you probably won't find much new here to entice you to switch. Mozilla should give Thunderbird more love. It's just doing what it has always done...the same old way. I was hoping for something new and innovative.

TB 11b1 is SO flaky - if I close the mail window, I can not re-open the window (command - 1) or see my mailbook (shift - command - b) - I have to quit TB to reopen either TB window.

Many times when I try to hide (command H) TB, it crashes - VERY unstable and a PITA! Far prefer TB over Mail and others due to extensions/plugins but TB11 v unstable compared with earlier versions.

anyone been able to configure thunderbird (osx) to receive/subscribe to rss feeds?

is this a windows only feature?

Found the solution for SLOW opening etc on mozillazine forums under the topic 'slow opening':

"There is a current bug which adds spurious lines to your pref.js file every time you open your address book, or load the contact sidebar. When enough of these amass, they can slow down initial address book/contact sidebar loading. See https://bugzilla.mozilla.org/show_bug.cgi?id=230580

The bug will be fixed in release 2.0. Meanwhile, you may need to clean out your prefs.js file to remove the spurious lines.

With TBird CLOSED, go to your profile, and make a backup copy of your prefs.js file that you can revert to in case of problems. Then open prefs.js in a plain text editor (NOT a word processor like MSWord, Windows' Notepad will do). Find and delete any line with the string servers._nonascii_ in it. If it has gotten bad enough for the slowdown to be noticeable, you probably have hundreds of them.

Save the file under its original filename and location. If the editor you're using gives you a choice of formats, choose plain text or ascii."

IT WORKS: the original posting was by 'makaiguy ' - for further info, search the forums for "slow opening" - just passing on the info to others who are experiencing this bug..

solution above works - I had almost 2000 lines of junk in my prefs file. deleted them and Thunderbird is back to its snappy self.
