Using Tampermonkey (for Firefox) could be a temporary solution.

Works fine in stable firefox
No longer working and cannot re-install
Love this script, but a couple of days ago it stopped working. I uninstalled and then tried to re-install. Now I cannot even get the script to install. I get a popup giving a long list of errors. Here is a link to a screenshot of the errors. http://imgur.com/IUgyALC I am not sure if it matters, but I am using the latest nightly build of Firefox. Any help would be greatly appreciated.
