Hi all! Ok, we're in 2025, and I experienced the same issue with my TB snap 140.2.0 esr on a Kubuntu 24.04 machine. First: the steps mentioned by osomon (Olivier) #3 are helpful to understand what's going on. My relevant output was:
JavaScript error: chrome://pippki/content/exceptionDialog.js, line 162: NS_ERROR_MALFORMED_URI: Component returned failure code: 0x804b000a (NS_ERROR_MALFORMED_URI) [nsIURIMutator.setPort] This seems to be a bug related to the snap versions of TB. (I couldn't find the issue in the DEB versions) But I 'solved' the issue by entering the IP-address of the domain. Then TB seems to reinitialize it's procedure to give an opportunity to add an exception. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to thunderbird in Ubuntu. https://bugs.launchpad.net/bugs/1904789 Title: [snap] Cannot confirm security exception for invalid certificate Status in thunderbird package in Ubuntu: Confirmed Bug description: Note: This bug is specific to the Snap version of Thunderbird, I can't reproduce it with the Ubuntu-packaged version for example (which I have installed on Ubuntu, used for multiple years and stopped using recently to get the more recent versions of TB available with Snap). When a certificate problem arrises with a server from which Thunderbird tries to retrieve emails, the "Add Security Exception" window gives you the option to "Confirm Security Exception" (meaning that Thunderbird will overlook the invalid certificate). The problem is that nothing happens when I click the "Confirm Security Exception" button. I've tried the usual workarounds, including removing the email account and adding it again, to no avail. The peculiar thing here is that I have had certificate problems before, when using a non-snap version of Thunderbird, and clicking the "Confirm Security Exception" button has always worked. Not with the Snap version it seems.
