When I try to log in to my account at t-mobile.com I get the message that Firefox is not supported in incognito mode. https://www.t-mobile.com/unsupported_firefox_incognito


Logo Corporate Firefox is no longer supported in private mode

The Firefox browser is no longer supported in private mode on our site. To continue, please take Firefox out of private mode or choose another browser. We recommend Chrome, Safari or Edge.

Do I have to compromise my privacy and security just to use the t-mobile.com website?

This happens only on the t-mobile.com website and only after I try to log in to my account. If I don't try to log-in to my account their website works just fine with Firefox.

Thanks for any help on this situation.

Chosen solution

Thanks for trying CraigS26 but that didn't work for me.

I DID find a solution to the problem though. Turns out that there is an extension for Firefox that is called "Hide Private Mode". https://addons.mozilla.org/en-US/firefox/addon/hide-private-mode/

Adding that extension to my Firefox browser allows me to use the t-mobile website without any problems. Firefox is still in Incognito mode and it still blocks the same tracking cookies at the t-mobile site, just now the site cannot tell that my browser is in incognito mode.

A FF Forum I follow a lot always asks IF a post-er tried in Help/ Troubleshoot Mode (eliminates Extensions, certain Settings) OR with a Test Profile easily created by Profile Mgr ( in RUN: firefox -p ).... Give thata shot and IF it works it's an Addon or Setting that is interfering, and the only way to know which one(s) is by starting with whatever worked and adding back Addons or Settings until it breaks. No easy guess here, I think.
