Can you reproduce the issue in Safe Mode[1]?
If yes and you can reproduce the issue in Safe Mode,
can you still reproduce it even with clean new fresh profile without any addons (extensions and plugins)[2]?

You can also try a standard troubleshoot and diagnose procedure[3],
mostly look on "Check for conflicts with your Internet security software"[4].

Next time please write bug reports in standard ways[5], as it's support request, not bug.

Is this still reproducible on your end ? If yes, can you please retest this using latest Firefox release v50.1.0 and latest Nightly build (https://nightly.mozilla.org/) and report back the results ? When doing this, please use a new clean Firefox profile, maybe even safe mode, to eliminate custom settings as a possible cause (https://goo.gl/PNe90E). 

Also, I have noticed that you are using Firefox x86 on an x64 system. Can you try with Firefox x64 to see if this issue is reproducible? Here is the link: https://www.mozilla.org/en-US/firefox/all/
