I can´t sign my add-on

Add-ons addons.mozilla.org
#1

Starting with Firefox 53, new extensions on this site can only be WebExtensions.

I have a restriction on install.rdf and every time show me the same version error

em:minVersion33.0a1</em:minVersion>
em:maxVersion43.0</em:maxVersion>

Help!!!

#2

You can submit new add-ons as long as the maxVersion is lower than 53 and you have strictCompatibility also set. Otherwise it’s not possible to submit new legacy extensions.

#3

Is this still true? I’m building an add-on for a client that unfortunately needs to use legacy API’s (toolbar). The add-on will only be used for Firefox 52, and will not be distributed via AMO. When I try to use the jpm sign tool to sign the add-on, I’m told it failed because “Starting with Firefox 53, new add-ons on this site can only be WebExtensions”. The pertinent block of my install.rdf is:

<em:targetApplication>
  <Description>
    <em:id>{ec8030f7-c20a-464f-9b0e-13a3a9e97384}</em:id>
    <em:minVersion>52.0</em:minVersion>
    <em:maxVersion>52.*</em:maxVersion>
    <em:strictCompatibility>true</em:strictCompatibility>
    <em:multiprocessCompatible>false</em:multiprocessCompatible>
  </Description>
</em:targetApplication>

Any thoughts on why the sign tool is still complaining? Thanks!

#4

It may be true for unlisted add-ons, but I’m not entirely sure.

#5

OK… is there any way to determine if I’m getting that error / refusal to sign because of something I’m doing wrong, or because there was an undocumented policy change on Mozilla’s side?

#6

I was able to upload a new add-on for signing using strict compatibility. Looking at the code you pasted, I think multiprocessCompatible and strictCompatibility aren’t working because they’re inside targetApplication. I think they need to be at the same level as the ID and the name.

@jorgev, thank you so much, that was exactly it. Moved those lines down and got my XPI successfully signed. Appreciate it!

I pasted strictCompatibility and multiprocessCompatible in every place as a property, as well as a tag, it didn’t helped.

Only issue I have:

Yes, AMO is not accepting any new legacy add-ons. Either you need to port the add-on to use WebExtensions, or disable signing wherever the add-on is used.
