How to move map arrow in 32-bit Palemoon?

[Zedward]

I found non-working element, when I'm teaching with PaleMoon browser (newest 32-bit version palemoon_31.2.0.1-1.gtk2_i386
on page https://demo.fioco.ru/test/passing/1514 i can't use map (i need to move yellow arrow on map).
The test in Russian, but you can click blue button until reach page with the map.
Maybe I can add some libraries or add-ons etc.? Or I can another not heavy browser?

I cannot get your link to connect.

One thing to check is any Pale Moon preferences settings for how cookies are handled.

I have had issues with some web sites, because I had cookies blocked.
They seem to need their cookies active, for the feature to work.

https://demo.fioco.ru/login, big blue button, click on any test and click blue button until task with map.
I didn't restrict cookies nowhere.

I am having trouble connecting to the link.

I have also seen some web pages that will not load or work properly with palemoon which will work when using Firefox or Chromium browsers. GitHub is one of those sites. Also some web sites with interactive maps

As a matter of fact I am having trouble reaching many Russian sites and URL's these days so testing out and figuring out what to do to overcome problems like this have become more difficult to achieve.

I still cannot connect to your posted links.
Tried with several web browsers.

If your links are locations in Russia.

Seems something is blocking access from outside of Russia.
