And the ""Make Default"" button's grayed-out property reverts as well? </p><p>Do you notice any other preferences not sticking? I ask because the Default Account designation is stored in the prefs.js file, located in your Profile. If one preference is not sticking, I would expect to see other properties not sticking, either. </p><p>First thing to try is to restart Thunderbird in Troubleshooting Mode. Go to menu item <Help | Troubleshoot Mode...>. Let it temporarily, not permanently, disable all your add-ons. After it restarts, try changing the default account again. If it's successful, that could indicate a misbehaving add-on. </p><p>Please let us know the results. If that doesn't do it there are some other things to try. </p>",rednoise,false,0,0
