Hello,

I'm using TB from years but now first time I'm facing this problem with TB. When I open TB it starts building summary file for few folders and during startup I also get address book message: Unable to load address book file abook.mab locked by another application etc.

Yesterday I have deleted all MSF files in every folder of my default profile folder and it worked yesterday but today again this problem occurs. I can't see any address book loaded in address book page, white blank page.

Any body who can help me with this? Thanks

To diagnose problems with Thunderbird, try one of the following:

  • Restart Thunderbird with add-ons disabled (Thunderbird Safe Mode). On the Help menu, click on "Restart with Add-ons Disabled". If Thunderbird works like normal, there is an Add-on or Theme interfering with normal operations. You will need to re-enable add-ons one at a time until you locate the offender.
  • Restart the operating system in safe mode with Networking. This loads only the very basics needed to start your computer while enabling an Internet connection. Click on your operating system for instructions on how to start in safe mode: Windows 8, Windows 7, Windows Vista, Windows XP, OSX
If safe mode for the operating system fixes the issue, there's other software in your computer that's causing problems. Possibilities include but not limited to: AV scanning, virus/malware, background downloads such as program updates.
