Firefox "Did Not Connect: Potential Security Issue" is incomplete.
by Brant from LinuxQuestions.org on (#52BH9)
Occasionally when I go to a site Firefox will show the message
"Did Not Connect: Potential Security Issue"
and will offer two choices:Go Back (recommended) and Advanced.
If I click on Advanced, it then offers the option of ignoring the recommendation and continuing on to the dubious site (for some reason this always happens when I go to look at the Washington Post!).
The other day I went to look at a site and the Firefox warning came up, but only partially: the lower part of the website page was showing, and when I clicked on Advanced, apparently the rest of the Firefox window was hidden. Possibly the screenshot will make this clear.
This may well be a page I shouldn't be visiting, but my question is rather, what has happened to the Firefox page, and is there a fix?
I am running the latest Firefox with Linux Mint 19 Cinnamon.
Thanks.
