I have had an issue with an extension conflict and just figured out it is related to using mootools-1.2.4-core-yc.js.
When the script is loaded in a browser overlay XUL file there are two conflicts I have seen.
1. If you bookmark a new page, you do not receive the "Edit This Bookmark" dialog which you typically are prompted with.
2. It just so happens it also conflicts with the Gmail Checker extension. When you select "Check mail now" rather than going off and checking my mail I am prompted with the "Gmail Checker - Login" dialog and can not close the window. I need to use task manager to kill the session.
Of course I am more concerned about impacting default Firefox behavior (#1), but it is rude to impact other extensions as well.
You can rem out the script include for mootools repackage and run to see it is clearly the mootools file.
When I substitute that with the jquery.js, I don't run into the same conflicts. Do I need to bite the bullet and convert everything to jquery? Or is there a way to prefix the functions of a third party js file in a namespace to avoid this conflict?
Any help or ideas would be greatly appreciated.
