Missing chess pieces

[WE]

Please goto https://lichess.org/

Using normal mode no pieces are displayed. Private mode works fine.

Does that also happen in Troubleshoot mode (https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode/)?

If not, return to normal mode, then disable all > re-enable one at a time and test

[WE]

Neither troubleshoot mode nor disabeling all extensions solves the problem.

Some screenshots:
