Ok, the firefox is fast on my laptop, however, sometimes, when I open a tab or two, and it starts to load and about half complete or so, the loading will look like stop there, but it's still loading. And when I open a new tab with a bookmark, the other pages will quickly finish load. It's now like sometimes I need to give a enzyme for the firefox to load the webpage, otherwise it will just stay at some point and eventually of course will complete the task before I die. So does anyone know why that is happening? Please give some advice! Thank you very much!
