Could you explain your problem better?

Note that you use a very old and outdated Firefox 30.0 version according to the System Details list. It is quite possible that websites do no longer support this Firefox version, so you need to update to a more recent version. Verify that you meet the System Requirements (GTK+ and GLib) for the current Firefox release. *https://www.mozilla.org/en-US/firefox/system-requirements/ *https://www.mozilla.org/en-US/firefox/87.0/system-requirements/
