There are quite a few reports with that crash signature:

Look like a problem with running JavaScript.

Does it happen on specific pages?

Does it help if you disable the JavaScript JIT compiler temporarily as a test?

Try to set these two prefs to false on the about:config page to disable the JavaScript JIT compiler for scripts on web pages. 

javascript.options.methodjit.content
javascript.options.tracejit.content

If you still see the crashes then do the same with these two for Chrome content (browser and extensions): 

javascript.options.methodjit.chrome
javascript.options.tracejit.chrome

To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website.
If you see a warning then you can confirm that you want to access that page.

  • Use the Filter bar at to top of the about:config page to locate a preference more easily.
  • Preferences that have been modified show as bold (user set).
  • Preferences can be reset to the default or changed via the right-click context menu.
