I do not see IDM context menu items in FireFox. How can I enable them?
First please make sure that IDM is properly integrated into FireFox.
Then please check that context menu items for FireFox are enabled in IDM settings. To do this open "Options→General" IDM dialog and press "Edit" near "Customize IDM menu items in context menu of browsers".
Then select "FireFox and other Mozilla based" tab and make sure that all context menu items are enabled.
If this does not help, then some application on your computer removes IDM menu items from FireFox context menu. It can be some kind of security program: FireWall, Antivirus, SpyWare/AddWare Remover. You should check your settings in such applications. Or it can be some kind of extension for FireFox. In this case you can try these instructions.
