Rated 2 out of 5 stars

I uninstalled this addon and now if a web site does not load in a few seconds i have to refresh it. what about:config setting should i reset to fix this?

This review is for a previous version of the add-on (3.2.0). 

TryAgain is not invasive; it does not make any changes to any Firefox settings. It quite literally and simply reloads the failure page after a specified number of seconds. Uninstalling the add-on will remove every trace of it, so something else must be causing your connection difficulties. Perhaps a problem with your ISP?
