I'm developing a Firefox extension that runs a local Flash object (SWF and HTML files).
I'm new to extension development so I followed a few web tutorials to run a simple Hello World application in a new window in Firefox. The test extension was simply a popup window that opened when you selected it in Tools menu. All in all, I know that my Flash object works within a Firefox extension. My problem now is that it doesn't run in a sidebar. I've tried calling the object through <browser> and <iframe> tags (since they seemed the most relevant).
With <browser> I essentially get an error message. Pre-fabricated test and a button (created by Adobe) show up asking me to install Flash Player 10 or higher. I double-checked and I'm currently running the most up-to-date version of Flash Player (10.1... down to the most recent build as of 7/31).
With <iframe> the object loads... sort of... it's all just black. I know the object is trying to load because I have test text at the bottom to see if the object is at least sort of loading (like right now).
Has anybody else tried something similar? I have no idea if it's a version incompatibility because I've never developed on any version before 3.6.8 (newbie, remember?). Do sidebars even support Flash objects?
