Firefox 4 has got it into its head that tabs are better than windows, despite the fact that tabs use up more UI and look ugly, while windows are nice and clean.
In order to promote their tab agenda, they’ve changed the order of the context menu so your muscle memory for “Open Link in New Window” now brings you “Open Link in New Tab”. Ugh.
Luckily, there is an answer for this.
Create a userChrome.css file in your profile/chrome directory (on Windows, C:\Documents and Settings\user\Application Data\Mozilla\Firefox\Profiles\somethingrandom.default\chrome\):
#contentAreaContextMenu > * { -moz-box-ordinal-group: 2; } #context-openlink { -moz-box-ordinal-group: 1 !important; }
This doesn’t change the order under the file menu, but at least when you’re using the context menu it will work right.
