I installed that version of Menu Editor to see if there was any interference between the two extensions, but the Flip and Rotate menus still appear on right-clicking an image, and both menus appeared in the Menu Editor, so it might be another extension involved. You can create and switch to a fresh Firefox profile and just install Flip or Rotate Image to see if it works there (see http://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles#w_starting-the-profile-manager ) and from there find the culprit extension or setting causing it in your original profile. If you need further help, these reviews are the wrong place to ask, click on my homepage or just visit irc://irc.mozilla.org/firefox in a good IRC client.
