Months ago, we posted a neat way of getting to log-in to two different Gmail accounts at once using a IE Tab workaround. The principle behind this is to utilize the two browsers to use different cookie information that allows you to have two separate sessions with a site.

Now here’s a new update on the matter. CookiePie is a Firefox add-on that manages cookies on a per tab basis. That means that you will now be able to use solely the Firefox rendering engine to view the sites.

Here’s a video sample of how it handles two Gmail accounts simultaneously:

However, the author’s site indicates that there are still a few kinks that need to worked out with this one (e.g. conflicts with Tab Mix Plus) but it is a promising work in progress. Especially for those of us who need multiple log-in sessions.
