you need to figure out first if it's Thunderbirds fault, some of the used extensions or, unfortunately also possible, some problems with your profile. So you can start Thunderbird in safe-mode, this will disable your plugins temporarly, and check if Thunderbird is working if expected. For safe-mode start Thunderbird from a CLI by calling $ thunderbird --safe-mode To see what Thunderbird is currently doing (or not and wanted to see where this happen) you need to set some environment variables and start Thunderbird again from a terminal. $ NSPR_LOG_MODULES=IMAP:5,SMTP:5 thunderbird Or with a log file 'thunderbird-activity.log' placed in your $HOME you need a variable more. $ NSPR_LOG_MODULES=IMAP:5,SMTP:5 NSPR_LOG_FILE=~/thunderbird-activity.log thunderbird If Thunderbird is working normally you "just" need to find which plugin is causing problems. In some cases user reported after creating a new profile the issues went away. Normally such problems you seems to experience are incompatible plugins on your system. Regards Carsten
