I really like this add-on but I had to disable it after the FF26 upgrade. However, the 2.2 version worked once I disabled baselinejit option per Guillermo's recommendation (below).

This review is for a previous version of the add-on (2.2.1-signed.1-signed).

It seems that the crashes experienced by the users are related to the new Javascript JIT Compiler Called ION Baseline. Disabling it seems to solve the problem. You can disable it by setting javascript.options.baselinejit.* in about:config to false
