I am recalling, ever since I have updated Firefox web browser to version 10.0 my browser starts to crash once in a while, when browsing sites like Facebook and when closing multiple tabs. The problem got worse from 10.3 as the browser keeps on once or twice in a week. I am currently on version 10.6, the latest version of the web browser and my browser crashed 2 times yesterday. once while scrolling through Facebook and the other time while closing multiple tabs and the browser crashed once the day before yesterday as well, you can say I had multiple browser crashes this week.

Please note : I am on the latest version of iOS.
