As you know there is an option in facebook to load more of news feeds the more you scroll down by clicking the link "Older posts" on the left side of the end of the news feeds page.
The more I scroll down (get older posts) the more firefox slows down. The text boxes of the "share boxes" - which are popping out by clicking the link "share" on the right bottom side of each post - are getting so slow that I can wait almost 30seconds after I finish writing a sentence to see the sentence in the textbox. Also the reactions and scrolling of ffirefox are getting slower.

Reproducible: Always

Steps to Reproduce:
1.Login to facebook and open news feed page
2.Get older posts (after 5 times the lag occurs but after 7 times it's extremely lagging)
Actual Results:  
Firefox slows down and lacks on reaction speed.

Expected Results:  
Should behave normally? As fast as ever..

I use the personas "Dark Fox", which you can see here: http://www.getpersonas.com/de/persona/5918
