<p>There's only 3 reasons i can think of, for the cloudflare checking:
</p><p>1. The sites have implemented Cloudflare's "Im under attack" mode.
(Sites you have mentioned so far, all have "Im under attack" mode turned ON)
2. You have installed an extension in Firefox that alter/randomize your User Agent.
3. You have installed a malicious addon, that sends automated unsolicited requests.
</p>UP, Still need help on this, please? :(

<p>I don't think so, I tried that site on other PC with Firefox too, it was working. Same in mobile.
</p><p>Okay, if you think that it has nothing to do with Firefox at all but with my PC, then what solution can solve this? Contacting their website directly?

The site in question (and others mentioned) have set their site to "Under Attack Mode" in the cloudflare dashboard which checks every visitor, everytime they visit.
Google, Yahoo, Yandex, Bing etc. bots are whitelisted by Cloudflare and won't be checked using this option. (however you can block everything manually if you wish).
There is no fix, but reaching out to the site owners, and ask them to disable the "Under Attack Mode" and instead employ their own security rules through Cloudflare.
You probably won't have much luck though, as most of these site owners don't know what they're doing, and thus simply checks "Under Attack Mode" to be safe.
<strong>Edit:</strong>
As for ddlcmods. fun i've tested it in 5 different browsers now, including Edge multiple times and got the browser check everytime, even with persistent cookies, and privacy clearout disabled.

I see that the cf_clearance cookie isn't created and isn't send with the second request when following the location header.
</p><p>To get success both cookies will have to be send to the server.
Request cookies:
__cfduid: &lt;data&gt;

<p>You can remove all data stored in Firefox from a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History -&gt; Show All History" or "View -&gt; Sidebar -&gt; History").
</p><p>Using "Forget About This Site" will remove all data stored in Firefox from this domain like history and cookies and passwords and exceptions and cache, so be cautious.
If you have a password or other data from that domain that you do not want to lose then make sure to backup this data or make a note.
</p><p>You can't recover from this 'forget' unless you have a backup of involved files.
</p><p>If you revisit a 'forgotten' website then data from that website will be saved once again.
