Firefox Portable 80.x, 81.x (Win10) does not render atlassain.net pages

Since version 80.x Firefox Portable is not able to display some atlassain.net pages, e.g. login page to https://teleconnect.atlassian.net (no public page, but login screen should appear). It regards to newer pages of atlassain.net, older pages seem to work correctly. The Firefox 80.x installed version (Win10) -not the portable one- does not have this problem.

Make sure you are not blocking content.

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Thank you, I'll look there. Safe mode does not solve the problem. Andreas
