Hello,
This seems like a conflict with other system software or an installation problem.
To diagnose such conflict problems with Thunderbird, you can 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 '''[http://en.wikipedia.org/wiki/Safe_mode 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: [http://windows.microsoft.com/en-us/windows-8/windows-startup-settings-including-safe-mode Windows 8], [http://windows.microsoft.com/en-us/windows/start-computer-safe-mode#start-computer-safe-mode=windows-7 Windows 7], [http://windows.microsoft.com/en-us/windows/start-computer-safe-mode#start-computer-safe-mode=windows-vista Windows Vista], [http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/boot_failsafe.mspx?mfr=true" Windows XP], [http://support.apple.com/kb/ht1564 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.
If the above doesn't help you can perform a ''Clean Reinstall''. This means you remove Thunderbird's Program Files then reinstall Thunderbird. Please follow these steps:
#[https://support.mozilla.org/en-US/kb/profiles-tb?esab=a&s=TB+profile&r=0&as=s#w_backing-up-a-profile Backup your current Thunderbird profile]
#Download the latest version of Thunderbird from http://www.mozilla.org/en-US/thunderbird/ and save the setup file to your computer.
#After the download is complete, close all Thunderbird windows (Click Exit/Quit from the menu button on the right).
#Now, go ahead and reinstall Thunderbird:
##Double-click the downloaded installation file and go through the steps of the installation wizard.
##Once the wizard is finished, choose to open Thunderbird after clicking the Finish button.
#At this point you can [https://support.mozilla.org/en-US/kb/profiles-tb?esab=a&s=TB+profile&r=0&as=s#w_restoring-a-profile-backup restore your backup] or setup Thunderbird accordingly
<b>WARNING:</b> Do not run Thunderbird's uninstaller or use a third party remover as part of this process, because that could permanently delete your Thunderbird data, including but not limited to, extensions,emails, personal settings and saved passwords. <u>These cannot be recovered unless they have been backed up to an external device!</u>
Please report back to see if this helped you!
Thank you.
