Cloudflare ddos protection looping #269

If you are reporting a bug, then providing the following is helpful:

I saw the issue for cloudflare protected sites using captcha, i had to disable Privacy Possum for https://themusicfire.com/ and https://the-eye.eu/public/MSDN/ but these two sites don't use captchas, just some ddos cloudflare protection that you have to wait 5 seconds and the page refreshes itself and goes to the site. But with Privacy Possum enabled the pages were refreshing in a loop never reaching the actual site.

Looks like Possum is removing the added url string: https://themusicfire.com/?__cf_chl_jschl_tk__=21d93aed01ce9d6407d6947838c9cf7766eb3b8c-1602526015-0-Aaa77uXrW-T-TN45j6yNB97YehFWqXnF3h07zrWXUln8dSEskK6zqb5TzNG_N91HABu5nT-Rh-HBUlNh36PjvfFDMHrbRMuhDlByLWGiP0AWm2xQoNV7qZcxPp2ObFiMLdLXSqu2fuZv_-qbWL-IhsBN-sMcwwCrdkHQZgC3D7E80zCplnzVeFW7VxOSQbx18B5mmwcbsOMiaCTKmZxS_CQqNjrRooyJx5g-wUsJptu18MkalROZU1AqYKc3thBX8Wk72Z_US81BQ6thPAkPJro

And maybe cloudflare needs it to verify someting, maybe related to cookies? Because i had to enable cookies for those sites. If i disable cookies theres a message to enable cookies and refresh page. After enabling cookies but also leaving Possum enabled it loops the same page. If i disble possum it goes to the actual site but with that huge url.

Same here (Firefox 82, various Linux distros). I ended up just removing PP for now because so many of the sites I use were impacted.

Yeah i also switched to Firefox 82 but the problem remains which is expected. Although removing Possum is not what i did because it does its thing for everything else. Its a one time disable for every site, or disable and re-enable after the cloudflare thing and it works for some time even after page reloads and probably browser restarts.
