Thunderbird is Slow - Comments Page 2

Another piece of crap you have to keep screwing with just to get it to function properly. Worth just about what I paid for it.

Thunderbird doesn't delete your messages, even if you click on 'Empty trash'. To get rid of your deleted mail once and for all, you need to compact your folders. Just go File -> Compact Folders.

This way, it might be become a little faster.

I disabled the Google Contacts extension and it improved considerably.

i also had that problem, but after i deleted the file mimeTypes.rdf on thunderbird profile folder, it start very fast. it created another file but this time a small one (5kb), the previous one i deleted was 300Mb. delete file without thunderbird started.

Thunderbird used to be good, but now it's a total waste of time.
Slow, Failing, missing basic functions.
I suspect it has Lotus Notes technology, that's why.
Go to Outlook.

I just uninstalled Panda Cloud (Free) to see whether it would stop TBird from hanging on open. It did. Using now, for instance, Microsoft Essentials and there are no TBird or browser hangs.
Windows 7/64bit
I did see Panda almost acknowledge the problem in one forum posting

User added "Add-ons" are the likely offenders. Tools/AddOns/Extensions ... then disable all of them. Close and reopen TB. Now reable them one at a time, close and reopen TB, to find out which ones are causing the load problem. I've found that any ADD-ON EXTENSION that SORTS FOLDERS or SEARCHES MESSAGES will make TB slow on startup.

1- Compact all directories. 2- Use Windows ReadyBoost with a new USB thumbdrive (16Gb), to add memory. 3- Delete all extra emails older than a month or so. 4- Click all unread emails. 5-Organize emails into directories if they are kept.
