Yesterday I noticed that ffirebox Firefox did not run on my Windows XP PC at work when I clicked the icon. This morning I tried double clicking the .exe file in explorer. "Nothing happens" Checked task manager to see if it was already running, but no it was not there. Called up my work IT and they said they did not support Firefox, but they did not block it either.
Tried uninstalling, and reinstalling Firefox, but that did not work either.
