I found that " Read it Later" and " Lat Pass" are inveriably opening webpages whenever I open Firefox. This is annoying. Being disgusted I have ultimately uninstalled Firefox - though I have been using it for over 5 years. Another point - what is the point of version updates, where several Add-ons are incompatiable. Further the speed with which the browser opens is after all these updates remains alnost the same. There are other browsers having superior speed- Chrome or Opera. I note that even IE 8 is opening faster.
