I have contacted Arduino as pert wrote, and they wanted a video that shows how the problem. I was able to make a screenrecording that shows how I was kicked to
https://forum.arduino.ccAfter reducing my security settings and cleaning all cookies and website data, it did not happen anymore.
However, there is one single situation that still does it:
- Log out and close Firefox.
- Start Firefox
- Goto forum.arduino.cc
- Do not log in.
- Move mouse over "Project Guidance", and Firefox shows the correct link (with board=3.0).
- Click it, and I get kicked back to
https://forum.arduino.cc/This happens also with "Microcontrollers", but not with the other links.
When I click on the item of the "Last post", then it does not happen (it did before).
I can fill in the URL bar the text: "
https://forum.arduino.cc/index.php?board=3.0" and I also get kicked.
Turning off security settings and add-ons one by one was not enough to find the troublemaker. I guess it is some kind of combination.
I'm not familiar with the Firefox developer tools, and I can not find a difference between those two links and other links.
