FF extensions in MacOSX
For some reason sparkrocket extension isn’t working on the mac, but interesting enough if I run the browser in the browser by using chrome://browser/content/browser.xul with the sparkrocket extension installed it works perfectly.
I couldn’t find browser.xul by searching the OS (find . -name ‘browser.xul’). I searched the net and found that it is in a jar file. /Applications/Firefox.app/Contents/MacOS/chrome/browser.jar. So that mystery is solved.
To make a somewhat long story short, the problem turned out to be that my nesting of a tag <menubar> with the buttons inside was the problem. The reason I had used <menubar> was to position both buttons together. When I removed <menubar> I added a position to each of the buttons and all was well.
