After last OS update Why does my ipad browser crash every time I try to watch a video?

I have tried several different browsers and the same thing happens....i have also noticed that when using facebook in a browser the page will load the timeline and when I scroll down to the bottom of the page it is stuck with the loading icon....I have an iPad 3 that was running fine until the latest upgrade...I have tried all the usual fixes...closed all open programs, rebooted, cleared cache...etc. Any help is appreciated.
