i have a problem with mouse pionter in webpages since i've updated my firefox . when i'm reading a webpage and i click somewhere in the webpage,my mouse pointer goes from the normal pointer to the typing and selecting one. i also can not scroll up and down the page with up and down buttons on the keyboard because it goes straight to the top or the bottom of the page ! i only have this problem with mozilla firefox and it started when i updated my firefox about two months ago .
