I open Firefox (app was not previously running, opening from fully 'closed') and I will type in a complete web address into the address bar. The page will load; however, as soon as I click a link on the homepage, it just keeps loading, with the spinning circle on the tab. What is strange is that I will go use safari and chrome, and I will not have this same problem with these two browsers. So it's not my internet; it's firefox. I go on to visit dozens of pages on the other two browsers, meanwhile Firefox will still be loading that one page originally entered. My workaround is: open firefox, go to one of my bookmarks, let it load, CLOSE firefox fully, and open it again. Then the problem is gone and I can browse freely without the internet cutting out. I have done this for months. Firefox never allows me to go past a first loaded page without closing the browser first, and then reopening the browser. I have the most recent Firefox browser on my Mac air. I have ATT high speed (cable) internet, wireless. Thanks!
