I don't think I have an unusual amount of TLS issues per site browsed, I just browse many sites. For example, today wikiless.org's certificate is expired, and I cannot ignore the error in Waterfox because of HSTS, unless I "forget about this site", which removes all my History entries. I would estimate that I have about one issue per 100 sites browsed, which adds up.
