I use Zorin OS 17 Pro and Mozilla Firefox for Zorin 1.0 Version 132.0 (64-bit).
Currently I get an error after logging in to gmx.net
“Your browser is not supported.
You are trying to log in to your GMX mailbox with an outdated browser. For security reasons, this is not fully possible. We therefore recommend that you use an up-to-date browser.* ”
When I moved away from Zorin to Devuan, Firefox ESR is the default browser and is Enterprise ready. In the video I made on the Beta version of Zorin 17, I replaced the standard Firefox with the Extended Service Release version, which is the only version of Firefox that can be 'locked down' for Enterprises and Education establishments:
There's nothing special about the Firefox version that ships with Zorin OS. It's installed from the Mozilla repositories directly. Are you sure you don't have anything installed or configured separately?
Set it up like on the Picture and click on ''Löschen''. But to say that: It will delete all Data's and Cookies. So, you will be logged out on every Service where you are automatically logged in.
everything is already done cookies and cache deleted.
can you click on “Accept” on the right button on the gmx page and continue?
Does this work for you?
Yes, it works fine no matter which option I click on the consent popup. You may want to reach out to them and ask them about it.
The "your browser is unsupported" is a complete fiction the vast majority of the time since web browsers (at least the major vendors) adhere to a standard specification. What's most likely happening here, as it's often the case, is that this site is loading ads and/or tracking junk from ad networks like Google & friends that can detect your browser and then block you with a false reason to get you to use another browser (talking about anti-competitive practices).
I have now uninstalled Firefox for Zorin and installed the Flatpak version and it works.
When I install the Zorin 1.0 version again, I get the same error on gmx.
With the Flatpak version 132 everything works, that is strange
Hmm ... that is strange. In other Cases there was mostly the Flatpak-Version the Problem because it runs containerized and when You use the APT Version it works.
I don't use gmx, I use web.de and there I don't have Problems with the Browser. Can you say how Your settings are set up and what Browser Plug-in's do you use?
