Started getting "connection is not secure" message on multiple, but not all sites-including some mozilla sites.

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connections and send their own certificate.

all my bookmarks disappeared.

What about the rest of your profile? settings, passwords . . .

Changed preference to "no proxy" & browser works. Now when I click on bookmarks the full list does not come down & I have to go to menu to see the list

Please provide a screenshot of both.
