Have been using FF for many years & each year run into various inconsistencies with the browser. Such as, not loading pics or videos on webpages, access to email is a daily challenge as to whether email page(s) will upload or not. Have tried several times to adjust what understand affects viewing pics/videos, but no changes. The email access is the most frustrating, as my email access will lock up or just not load. Even after clearing cache & restarting computer. Will have to go to another browser & email works fine & is very fast as not the case for FF. Maybe this is a computer issue, but other browsers work fine.
