We use Firefox ESR for along time in our organisation but with the last update, a specific page wont redirect to the ADFS page. In the latest normal version of Firefox it works and also other browser but not in ESR.

The webpage is https://rx-base.nl/ and https://preprod.rx-base.nl/

We are using the latest version of ESR. It gives a blank page with in the console a error:

Uncaught (in promise) TypeError: Fout bij het oplossen van modulespecificatie ‘@rxbase/root’. Relatieve modulespecificaties moeten beginnen met ‘./’, ‘../’ of ‘/’.

Please advise on what to do.

Chosen solution

So what I discovered is that enabling a feature called import maps fixes this.

In particular, setting this pref:

dom.importMaps

to true.

Do you use policy to manage Firefox?

That's quite odd. I'll need to debug and figure out what's going on.

I am able to recreate the behavior, and I'm wondering if it used to be broken on regular Firefox and got fixed at some point.

Also, FYI, we're releasing a new ESR in a few weeks and it will work there.

Hi Mike, that indeed solves the problem. We use policys indeed so we added it to the preferences (in JSON)

{ "dom.importMaps.enabled": { "Value": true, "Status": "locked" } }

Hopefully it doesnt break any other website :) , thanks for the solution!
