Ubuntu Mate Firefox is old, how do I install NoScript?

[needMoarNoScript]

I spun up an Ubuntu Mate VM to use a browser that works (been having issues with Firefox and Waterfox), and I'd liek to at least get some minimal extensions installed so I don't get infected.

Having problems with the noScript part because the firefox is so old.

I am on so many tangents to tangents that I'm almost forgetting what it is that i wanted to do. This is not an experiment, I'm not tinkering, I have stuff to get done and I'd like to get to it instead of get sucked into a rabit hole of linux updates etc etc rant rant

I can't find an old version of noscript that this firefox will install. The v5 on the main site won't install because it's not signed.

Isn't there a list of ALL the old versions somewhere? It's not on Firefox's add on site, that's for sure.

EDIT
Oh wait, you're probably using Firefox 52.0.1 or 52.0.2. You need Firefox 52 ESR.
