Hi, I'm not sure where to ask this, so, well, here... This is about changes to the SpiderMonkey javascipt engine between Spidermonkey 17 and Spidermonkey 24. Firefox 24, 25, and 26beta for Win7 don't seem to display scripts on pintrest.com correctly. Menus on pintrest draw with no content, or cause error messages, or pages are displayed with no content except headers. Parts of the page that aren't scripted seem to work correctly, so I'm assuming this is something with javascript. Firefox 21 - so Spidermonkey 17 - does display pintrest correctly. I wondered if something had changed between Spidermonkey 17 and 24, and whether I should tell someone so they could check. But, I don't know how to test this further, or where to ask, or how to do a bug report... Does anyone happen to know what I should do next? Sorry to ask dumb newbie questions :) And thank you
