I have uninstalled my 19.0 firefox to download the 4.0 for work and every 4.0 that I have found to download ends up downloading 19.0. I hate that I have to downgrade so much how ever I have to have the program for work. Please help. Thank You Catina with Nexgen Software Services

Firefox 4 is no longer supported, and has dozens (possibly hundreds) of known security issues. You should update to Firefox 19.0.2. If there is a specific issue you are having with that version, please clarify.

You can install a portable Firefox (ESR) version to access websites that do not work with the current Firefox release.
