VPN links don't work
Firefox 74.0 MAC OS Catalina and High Sierra. Been using it for years to access the VPN of my employer. In the last 2 weeks, none of the links on company website work. The home page loads fine, but none of the links there work anymore. Safari/IE/Chrome still work OK. Has there been a change that explains this?

Hi Ray, what happens when you click the links -- is there a specific error message?
Do you know whether your Firefox has been updated to use DNS over HTTPS? This feature bypasses your regular DNS servers and retrieves addresses from a point on the web (by default, using Cloudflare). There usually would be a little panel dropping from the main bar at some point about that. More info: Firefox DNS over HTTPS.
DoH sometimes causes issues with sites that may have different addresses for different networks of users. There's a way to make a site-specific exception, but first, is it even turned on?
You can check whether this is "on" on the Options page, and turn it off as a test if it's turned on now:
- Windows: "3-bar" menu button (or Tools menu) > Options
- Mac: "3-bar" menu button (or Firefox menu) > Preferences
- Linux: "3-bar" menu button (or Edit menu) > Preferences
- Any system: type or paste about:preferences into the address bar and press Enter/Return to load it
In the search box at the top of the page, type dns and Firefox should filter to the "Network Settings" section. Click the Setting button and scan down or scroll down to the last part to find the relevant checkbox (see attachment):
Did you check the Network Monitor ?
- "3-bar" menu button or Tools -> Web Developer
