when i try to open an https link firefox show only a white page instead of the document from the link.

First you mention a hyperlink, then you later mention a document. Show what you are doing and provide screenshots if needed. Provide steps to replicate.

In the first image you see the link where i want to open. In the second image you see what firefox show.

In other browsers (chrome or edge) the link working without issues!!!

Thanks and regards

Can we perform the same steps? If so, provide link(s). Do you have the same issue with Firefox in Troubleshoot Mode? https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode#w_how-to-start-firefox-in-4troubleshoot-modesf5safe-modesf

Did you try clearing the browser cache? https://support.mozilla.org/en-US/kb/how-clear-firefox-cache#
