Trying to install NoScript on a machine with the latest Firefox ESR and I get:

"not available for firefox 36.0" I have seen this more often in the past, don't recall what add-ons were involved.

What is causing this?

Hello there. Is NoScript an Add-On you're trying to install? If you could, paste the link of where this Add-On is located. We can assist you furthermore in the process upon more information. Thanks!

edit: Assuming it is this:

Here's a support article from the Add-On company;

There could be a potential delay in finding the updated version of your Firefox from the installation menu. Try above.

You are fast, thank you!

The machine with the issue got this problem after being updated to the latest ESR version. The previously installed version was a regular (non ESR) edition. The ESR versions do NOT install "over" the regular editon, so the machine ended up with both versions! I deïnstalled the regular version, and now all add ons work.

However, the regular version installed was not 36.0 but newer. So I still don't understand why I got the "not available for firefox 36.0" notification, that I get more often on other machines (specifically mentioning 36.0, while another version is installed).

your useragent (the information the browser sends to websites to identify its version) - apparently mistakenly - shows you're on firefox version 36. maybe some extension has overwritten it in the past. please refer to this article in order to reset the user-agent settings in firefox: Websites say that Firefox is outdated or incompatible even though it's the latest version
