Use the code of this extension to create a patch for 12 years old bug 18808

[Drugoy]

There is a bug in bugzilla: https://bugzilla.mozilla.org/show_bug.cgi?id=18808
It is almost 12 years old.
And your extension is actually does the same what the fixing of this bug should do.
So maybe you could use the extension's code to create a patch for that bug?
In that case your extension will become obsolete, but it will be integrated into Firefox, just as it is meant to be.
