When I start Firefox every now and then (Win7 machine, and I keep Firefox up to date), the language in all of the menus has changed from English to what I guess is Hungarian. I cannot navigate the menus to simply change the language (perhaps because I am not literate in Hungarian), and have only had success uninstalling and reinstalling the application. This seems to happen around every two weeks, which makes me wonder if it coincides with Windows updates, but I am not sure. Any preventative ideas would be great, as well as restorative ones. Thanks!
