Silencing the Thunderbird Update Reminder
As many of you have discovered, Thunderbird now sends you an update reminder screen when there’s a new version released. We researched disabling the update screen however it appears there’s no good “off switch” to automatically turn this off for everyone. The best way to turn off the reminder appears to be disabling the “Check for Update” setting in each individual Thunderbird profile.
If you're tired of the update "nag" screen, we’ve created “How to” documentation for turning off update checking and posted it on the SCLS Technology page in the Email section: http://www.scls.info/technology/email/tb_noupdate.html
