One of our readers contacted me to report a problem with Company B's website. Sure enough, when I checked their website, instead of the usual homepage I instead received a prompt to download a file!
I mentioned this to the company, and they tell me:
If you cannot see our site, it's because of an update to Mozilla Firefox. Mozilla browsers are not compatible anymore with all websites that use the .htm file extension.
The workaround is to wait for Firefox to add this functionality back into their browser.
All other stable browsers work fine with our site and others that use the .htm extension: Safari, IE, Opera, etc.
For some reason, Firefox removed this compatibility in their latest release.
I've just checked, and Company B's website works fine under Opera, but has the problem when using Mozilla Firefox.
