Extension Developer’s Extension for FF 3.0
If you’re developing add-ons for Firefox, you likely know the Extension Developer’s Extension by Ted Mielczarek.
It appears that this extension is perfectly compatible with the current Firefox 3.0 beta releases. However, as is the case with Live HTTP headers, the Developer’s Extension does not install out-of-the box (observed for Firefox beta 5). This is because Firefox now refuses to install extensions which specify a non-secure URL for
auto updates.
The fix is really easy:
- download the extension
- uncompress (using zip)
- edit the file install.rdf (top level): remove the em:updateURL property
- zip the whole shebang again, name the file somefile.xpi
- now Firefox will install the extension if you drop the file on an open window.
Four your convenience, you can download the modified extension here: extensiondev-030-no-update – but you really shouldn’t, download the original and make the modification yourself instead!

What’s annoying me is that I read on a blog that you can set extensions.checkUpdateSecurity to “false” in the pre-release versions of FF3, but I can’t find that property anywhere in my about:config for the final version released in June… Just as I’m starting to learn about that crazy XUL soup, and I was referred to the Extensions Developers’ extension by Mozilla’s own tutorial.
