[Solved] Add-on Incompatible Even with maxVersion

Add-ons Development
#1

I’m trying to make my first add-on, so I copied the install.rdf off Mozilla’s bootstrap extension walkthrough, but I keep getting the error “SteamChecker could not be installed because it is not compatible with Firefox 43.0.1”. It has nothing to do with maxVersion though since I can set it to 100 and I still can’t install it. I’ve already disabled xpinstall.signatures.required, but nothing I do works. Here’s my install.rdf:

<?xml version="1.0"?> ``<RDF xmlns="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:em="http://www.mozilla.org/2004/em-rdf#"> `` <Description about="urn:mozilla:install-manifest"> `` <em:id>steamchecker@foxslash.com</em:id> `` <em:type>2</em:type> `` <em:name>SteamChecker</em:name> `` <em:version>0.4</em:version> `` <em:bootstrap>true</em:bootstrap> `` <em:description>Grays-out & highlights owned/wishlisted Steam games on Humble Bundle</em:description> `` <em:creator>Zortrox</em:creator> `` `` <em:targetApplication> `` <Description> `` <em:id>{ec8030f7-c20a-464f-9b0e-13a3a9e97384}</em:id> <!--Firefox--> `` <em:minVersion>35.0</em:minVersion> `` <em:maxVersion>45.*</em:maxVersion> `` </Description> `` </em:targetApplication> `` </Description> ``</RDF>

It’s best if you link to the XPI so we can give it a try. The install.rdf metadata looks okay to me.

Sorry, it said it would allow me to upload anything that wasn’t an image, so I didn’t know if that was okay. Here’s the link:

The error is misleading. The actual problem is that the install.rdf is malformed because it has a & character. You should replace that with &amp;.

YOU’RE AMAZING! Thank you so much! That fixed the problem!

How do I mark as solved?
