For about the past 14 days, almost every time I log in to the forum with the Firefox browser version 151.x, I get a security prompt
This prompt never appears when using the Microsoft Edge browser.
Thank you very much for your report! I will ask our internal team to check if this issue occurs with certain browsers. Thank you!

Just updated to Firefox 152.0.
This time the prompt didn’t appear. Hope the problem is permanently fixed.
Just tested it with the new Firefox 152.0.4.
There’s no prompt.
I’m beginning to think it’s something to do with the forum, or maybe my location in Germany.
With Firefox 152.0.4, it seems the prompt no longer appears.
Your problem is simple:
Modern browsers now use various methods to protect your privacy. For example, third-party cookies, many trackers, and fingerprinting are blocked or masked by default to make it harder to identify you.
On the server side, websites also implement measures against bots and other unwanted “guests.”
This creates the risk that each side thinks the other is one of those unwanted guests. The captcha challenge you’ve posted several times is nothing more than a security check to determine whether your device is controlled by a human or a bot.
Unfortunately, the solution isn’t quite so simple:
A) The website operator lowers certain requirements—will they do that? Doubtful—probably not.
B) You reduce the security settings in your browser—should you do that? If you can define the QNAP website as a single exception, then yes.
C) You live with the captcha challenges.
Have a nice day 
Right now, I’m using Solution D: → with the Edge browser, there are no issues.
Edge only had a problem at the beginning of July with version 149.0.4022.98.
Firefox has been causing problems since version 151.x. Occasionally, it works with one of the many versions.
With the new Firefox 154.0, there apparently aren’t any problems either.
Things look good with Firefox 155.0 too
