…Is that it does not support organizing feeds in different folders. Not directly, anyway. An even larger problem is that it breaks feeds when you do so.
There is a workaround though, which is the only reason I'm posting this to a blog rather then just filing a bug report. (Blogs tend to be higher on Google searches then bug trackers, and I've found I'm often not alone in breaking things like this.)
If you make a directory and drag some feeds into it they will die. They just won't be updated. If you drag them out again, they still won't be updated. It's as if Thunderbird has lost track of them or something. If you try to re-add the atom/rss/xml address you'll get a notice that they are already in the system. It's really a mess.
Here's a work around I've discovered:
- Make a list of all the "dead" feeds.
- Export your feed list. It will only include the good feeds.
- Goto where ever your Thunderbird email directory is and back up the contents of "Mail/News & Blogs". Then, delete it.
- Open Thunderbird and import that list of feeds you exported at the beginning. It will be missing any dead feeds, but you'll have rebuilt the evil database, so it won't think you still have them.
- In that backup you made, there will be a file named feeditems.rdf. It's human readable, so you can look though it with a text editor and and manually pick out the addresses of your missing blogs.
- Manually put them back into Thunderbird using the "Manage subscriptions" dialog. Never touch any feed related stuff without using this.
- Note the usability issues and politely ask Mozilla to do something about it. 😉
Actually, there is no need for me to post a bug report. This bug has been known about for a year and a half. *cough*
