The website is for invoicing and the very large company that has their invoicing on there is not going to upgrade to fix the problem, they say just download a previous version in order to access the site. However, I cannot find on here where to download a previous version of firefox.

Chosen solution

The only previous version that is still supported with security updates is Firefox 3.6.x.

All other versions from Firefox 4 till the current Firefox 9.0.1 version are security and stability updates and add new features. It is not recommended to downgrade to such a version.

You can install the portable Firefox 3.6.x version to access websites that do not work with Firefox 5+.
