I customized my Portable Firefox, and it works very well with only one exception. I keep seeing "DOM Inspector" feature in "Tools" Menu. I do not want it, but I don't know how to get rid of it. Most the work I did were in browser.xul, and I did not see any reference to it in this file. When I deleted "inspector.jar" from my finished output (firefox\chrome\) folder, my application broke.
Any ideas?
Uninstall the extension. Never delete or edit files in the firefox folder unless you know exactly what will happen.
Vintage!
I deleted only 1 code-line in firefox\chrome\overlayinfo\browser\content\overlays.rdf file, and that did it. I also noticed that the "Help" menu items work the same way except "About Mozilla Firefox". This is very helpful. Thanks-a-lot.
