If you are a Firefox/Mac/Yahoo lover, you might have come across this annoying issue in Yahoo! Mail in Firefox [Mac version] that when you want to go to the home or end of a line with + Left Arrow [command – left] or + Right Arrow [command – right] , it acts like a browser’s Back or Forward button and messes up the email you are composing or sometimes even ruins the whole thing.
You can see that everybody blames Yahoo! about not following the standard rules in their editor over the net. But this can be fixed through a very very simple FireFox add-on.
KeyConfig is the handy tool for configuring your FireFox keyboard shortcuts. After installing if [and restarting the firefox] simply go to tools > KeyConfig and there search for “goBackKb” and “goForwardKb” and disable the ones allocated to + Left Arrow and + right Arrow.
From then on, on the newly opened windows this will be fixed and you will no longer have the same problem with those lovely combination [FireFox , Yahoo! , Mac]
