I'm at a loss for words here. I have a website I frequent and it has a really annoying behavior. I'm a developer so finally I mustered the strength to do something about it. I googled how to create an extension in Firefox and within 5 minutes I had a working extension that solved their annoyance. However, I can only load it temporarily. If I close Firefox, it goes away. When I try to actually install it, it says I need to have it signed. I have now spent the better part of an hour trying to find out how to self sign it. I refuse to believe that I have to submit this to Mozilla for me to be able to install my own code. Can someone please send me in the direction of how i self sign and install my own extension. I have no intention of publishing, I only want to run this for myself.

The only way to get an extension signed is via uploading it to the Add-ons website, but you can make the extension private and not have it listed.

Thanks for the quick answer. Absolutely ridiculous procedure. That Mozilla of all companies would require my own code be reviewed before I get to run it. Obviously not your fault and I thank you again for the quick response.

You can permanently install unsigned extensions on Developer Edition by changing xpinstall.signatures.required to false in about:config.
