Hi deggers......I am pleased that things have improved for you. It is purely my opinion that Firefox is the best of the Browsers, although a lot of folk are going for Google Chrome. Personally, I fail to see much difference between them, although it is claimed by some that Chrome loads faster, whereas FF has more useful 'Add-ons'.
I have both Chrome and FF and have made FF my default Browser. Consequently, as there is no limit to the number of Browsers that one can have in a Computer, you may wish to consider trying Chrome:-
