Hi Cheri, What version of Mozilla are you using? 6.0.1 works with Firefox 29 and up, available here: http://www.gnu.org/s/librejs/distribution/librejs-6.0.1.xpi
If that doesn't work, you can try the previous version here: http://www.gnu.org/s/librejs/distribution/librejs-6.0.xpi I hope this helps. Nik
