Since the last update I am experiencing the following error message: '''Thunderbird is already running, but is not responding. To use thunderbird, you must first close the existing thunderbird''' From Firefox if I click on any mail to link it tries to launch Thunderbird, even though it is already open, and I get that error dialogue. I am unable to click any mailto links at all now with this latest update. ''' 115.12.2 (64-bit) Release notes Mozilla Thunderbird Flatpak en-USthunderbird-flatpak - 1.0''' Does anyone have any extra information that might help? Currently I am having to right click and copy the email address, then Alt Tab over to Thunderbird and create a new message, and then paste the email address in, which is a nightmare.
