Greasemonkey - just the button that shows paid membership works. Everything else have disappeared.

Question

My beloved drop-down-list for placing caches from Geocaching.com to my different VGPS-lists have been gone for three days now. Also adresses and regions, the live map and so on. Once -  my drop-down-list showed up, but... in less than a minute it was gone again.

I've already tried to uninstall and install the script again, but it didn't help.

Is there anybody out here who knows something that might help?

I'm using Firefox Quantum 59.0.2 (64-bitars)

Answer 1

I think that I've solved the problem. I downloaded the latest version of greasemonkey and then checked all the boxex in the dropdown list in pgcs button on the top of gc page, saved the changes and made an reset. I've done this before a couple of times but with no result. But now after updating the greasemonkey the project gc script seems to be working all right again.
