Despite Firefox 2.0.0.10 being released in the past week, it looks like the Firefox developers will be forcing a critical update to Firefox 2.0.0.11 as soon as later today to fix a bug.  

A bug in just released Firefox 2.0.0.10 affecting an important <canvas> HTML element interface (.drawImage) has prompted Mozilla developers to rush a new update that fixes this bug that affects several web sites and extensions (FoxSaver, Fotofox) that rely on it to deliver the intended experience to their users.
