Cross-Origin XMLHttpRequest in chrome extensions

by

Two things; you need to make sure you are making a packaged app/extension and not a hosted one. Cross origin requests will not work with hosted apps. Assuming you got that part pinned down, you may want to try to put the following into your permissions: http://*/ . That’s the only one I have for one of my packaged apps, and it does cross origin stuff without any problems.
