codeforces take too long to load solution for firefox linux

I faced a problem loading codeforces every time i open my laptop, I had to wait up to 7 minutes for the site to load and maybe more to start the contest which give me time disadvantage, but finally I managed to solve it! at first I searched for any solution for this problem and I found some blogs talking about this problem too from long ago but found no solution for it so I started to find the solution myself. I realized that codeforces only take this long time when i started using linux and the reason was the enhanced tracking protection in firefox it makes the site slow to check if there is a malware or any suspicious activity but as we trust the site we can make an exception for it by doing these steps:

1. go to settings.
2. open privacy and security panel.
3. then in enhanced tracking protection you will find a button says manage exceptions.
4. click on it and just put the domain name which is "codeforces.com" and hopefully the problem is solved.

it worked for me so I hope my post will help solve the problem for all of you guys.

attention: if you find no change doing these steps then I recommend to undo these steps as it's safer for you just in case.
