I'm sorry if this is better suited in the Mac forum, but I figured here is most appropriate as it is referring to the WebUI (regardless of OS).
I have found that when accessing the WebUI on Transmission running on my server from Firefox on my MacBook Pro, I am unable to right click on my torrents in the torrent list to Pause, trash data, etc.
In Safari (which I prefer not to use) I can right click fine and administer my torrents as usual, but not in Firefox. In Ubuntu on my MBP, the only way I can get the right-click menu is to hold down the Command button when clicking on the torrent (I have of course tried this back in OS X Firefox, but it doesn't help there.)
My take on it is the interpretation of the right-click signal from the MBP track pad isn't being correctly associated to a right-click in the WebUI.
Is there any one who can look into this? Or am I better to file a bug on Trac?
Sorry to be a pain, but this is a bit of a pain!

Thanks,
Joe
