Details

Firefox 52 ESR is supposed to be compatible with legacy plugins until its end-of-life. IETab2 (https://addons.mozilla.org/en-US/firefox/addon/ie-tab-2-ff-36/) is a popular extension in some companies that still have some internal sites relying on ActiveX technology. This extension includes a plugin. Expected behavior : addons.mozilla.org should allow installation of this extension on all Firefox 52.x ESR versions Firefox 52 ESR should run this extension with no warning Actual behavior : addons.mozilla.org says it's incompatible with Firefox 52.1.2 ESR Firefox 52.1.2 ESR refuses to install it, and says it is incompatible with it. After some talk with Mike Kaply on the Mozilla Enterprise mailing-list, he believes it might be a bug : ---- My guess is that it was marked as incompatible because it includes a plugin. There should probably be a bug opened on this. It should be marked compatible for 52 because it needs to work on the ESR. ---- Workaround : Disabling the compatibility check by installing https://addons.mozilla.org/fr/firefox/addon/checkcompatibility/ makes IETab work fine, like on Firefox 45 ESR
Add-ons with binaries have strict compatibility set, which means that Firefox respects the maxVersion in the manifest. It's up to the developer to change the maxVersion of the add-on. The alternative is that you fork the add-on and create one that has a higher maxVersion. I know it's a bad time because you can't get it signed anymore, but clearly we're moving away from such add-ons, so decreased support should be expected in these cases. I'll ping the developers about this. Maybe they can change the maxVersion. More than that, we can't do anything.

The developer has updated the add-on's compatibility, so it should be working now on 52.
Thanks a lot for your help. But I don't manage to make it work yet : the addon is not marked as incompatible any more on https://addons.mozilla.org/en-US/firefox/addon/ie-tab-2-ff-36/ (which is a good point : thanks a lot to the developer for that) BUT it's still considered as incompatible by Firefox ESR 52.1.2 (at least for me). So it refuses to install it (or disables it if it was already installed). Uninstalling/forcing the reinstall of the addon did not help.
That's because of an additional compatibility block we had placed. I updated it now, so please try again.
My Firefox ESR 52.1.2 still refuses it. How should a locally installed Firefox be updated with the "compatibility block" you are mentioning? Is there a periodic update downloaded by Firefox? (if so, can it be forced manually?) Will we have to wait for ESR 52.1.3? (which would not be a big problem)
It's a remote check and should update fairly quickly, though there might be some caching involved. I suggest you give it a couple of hours and report back if it still doesn't work.
It works fine now : thanks a lot! Maybe the resolution should be changed to "fixed" instead of "wontfix"?
