What Causes the ‘Thunderbird not Responding’ Error?
There is a short list of possible causes for this problem. The list can be quite useful in order to correctly troubleshoot the problem and perform the right method. Check it out below:
Solution 1: Add Thunderbird to Exceptions in Your Antivirus
If you are using a free antivirus, chances are that it may be blocking Mozilla Thunderbird from connecting to the Internet properly or from accessing certain files on your computer. Either way, the problem can be solved by adding the program’s executable to the exclusions list in your antivirus. The process will differ from one antivirus to another but we have decided to list out the paths to this option in the most popular antivirus tools. Kaspersky Internet Security: Home » Settings » Additional » Threats and Exclusions » Exclusions » Specify Trusted Applications » Add. AVG: Home » Settings » Components » Web Shield » Exceptions. Avast: Home » Settings » General » Exclusions.
Solution 2: Disabling Windows Search to search messages
There is a problematic feature Mozilla Thunderbird uses and users have reported that disabling this feature helped them resolve their problem. The cause may have something to do with the overall integration of Windows Search into the program which needs to be disabled. Note: It might be useful to navigate to Advanced » Network & Disc Space and uncheck the Automatic Compact option.
Solution 3: Use Clean Boot to Find the Cause
Clean booting in order to successfully detect a service or a process which starts up with your computer is definitely the number one solution. Some other services simply bother the media player because of permissions and you will need to deduce which one it is by simple elimination.
Solution 4: Uninstall McAfee Internet Security
There are some antivirus tools which can really mess up some of your programs and slow down your computer. McAfee antivirus tools are a great example of antivirus tools which can sometimes do more damage than good on your PC so consider finding a better alternative! The problem can also be worked around by disabling antivirus shields and real-time protection while you are using Mozilla Thunderbird but that solution leaves your computer open to malware attacks and you can often forget to turn the shields back on.
