[Fx60-63] 'about:preferences tab' settings get wrongly applied to 'Options' window

[artasher]

Problem when using Options with Lightning and CusomizeMyBird. Using Thunderbird 60.3.0

See Bugzilla issue 1503441: https://bugzilla.mozilla.org/show_bug.cgi?id=1503441

Thanks

I think you are using the add-on wrong. It looks like you have enabled settings exclusively made for Windows 7s Aero Glass, but on your screenshots I see you are using OSs Aero Basic theme.

Can you confirm the issue only happens when "GMF" related settings are enabled?

Hi, I confirm troubles with the options > calendar button when using the add-on (2.7.4). In my case it started 10 nov.2018 when I upgraded Thunderbird from 52.9 to 60.3. As reported in https://bugzilla.mozilla.org/show_bug.cgi?id=1503441 the Option window partially dissappears, and TB is frozen. This happens also when all other add-ons are disabled. Solution: Have to exit TB with taskmanager. Then restart TB and disable CMB, and put the options menu on another tab. (Hope this description of the problem can help you).

Actually it would be good to know, which settings are used and whether the above GMF options are enabled or not.

I meant the settings on CMBs settings window/tab.

Uninstall CMB, restart Thunderbird and reinstall CMB. The restart is very important!

OK, found the issue.

Mozilla supposed to switch preferences from window to a tab in Tb60+, but still did not. The option causing this issue is the "alternative appearance" for about:preferences. Disable the option like seen on this screenshot:

Thank you Aris, that did the trick !
