Created attachment 8814627 [details] Heading sort.png User Agent: Mozilla/5.0 (Windows NT 6.3; Win64; x64; rv:50.0) Gecko/20100101 Firefox/50.0 Build ID: 20161104212021 Steps to reproduce: Thunderbird Preferences/Options sorting a column Clicking on the heading ‘Content Type’ or ‘Action’ sorts it. On Windows, both left- and right-click sorts a column or changes the sort order (ascending/descending). On Linux Mint, only left-click sorts a column. Is this the correct behaviour, as I understood on Windows only left-click should sort the column as right-click shows the context menu (as the behaviour in other sections of Thunderbird in Windows)? Thank you
Thunderbird 50.0b3 on Windows 8.1
Version: 51 Branch → 50 Branch
Is there a possibility to disable right click on this list headers?
