I don't get any error right now. Maybe it was a temporary glitch.
Please retry and let us know if the error persists.
Error still persist.
I run into similar problems when I try to access other wiki pages with Firefox, for example: https://wiki.geogebra.org/e... shows me this:
I'm using Firefox 77.0.1 (64-bit)
This problem does not occur using the latest MS Edge browser. It also does not occur when using the Chrome browser, so it is something with Firefox?
