Embedded Links in E-mails

[W4USNretired]

Just a question. I often receive e-mails from sources I have made purchases before. Most recently a notice from my credit card holder about a discount for a Lowes future purchase using their credit card. Others were from items listed by the poster. When I click on the link to take me to the item or website, I often get an error message that "Server Not Found". Even opening a new tab in Firefox, and manually entering the website, still results in the same error message. This is happening with a number of different sites, not just this one example. Is there a setting in Firefox that I need to change? Reading my e-mails on aol.com using the latest version of Firefox. Contacting some of the original posters about this, result in them saying they have no problems accessing the links via their e-mail post.

Disable VPN if you're using one
