Mozilla itself has the "Find" and "Find again" menu items under "Search". For consistency, the page source viewer should have them under "Search" also.
see bug 67414 - "Remove the search menu", part of which deals with moving the Search menu to the Edit menu.
Reporter: As there is no longer a "Search" menu in View-Source, are you satisfied with this bug?
It's already been decided in 67414 that the Search menu needs to go completely. (All find functionality should be under Edit, as it already is in View Source.) However, according to the drivers, this kind of UI shuffling won't be allowed to happen until after the 1.0 release. (Note that I don't necessarily agree with this, but am just passing it along.) Since this bug's intention seems to be "The Find interface is inconsistent", I'm marking this as DUP 67414. *** This bug has been marked as a duplicate of 67414 ***
