Hi I have figured this out that when I load Web pages and meanwhile I switch to other apps like Whatsapp, and then coming back to Firefox, Firefox loads again from the start instead of continuing from where I left. Even if the Web page is loaded fully and the loading process is completed and I switch to Whatsapp or any and then back to Firefox, Firefox again starts the process from beginning and loads the same page. This issue is not in chrome, as if Chrome is loading page and switch back and forth from other apps, chrome continues the process where I left and if the Web page is already loaded then Chrome doesn't start the process again and stays where it is. Please look into this, else you guys rock ;)
