Are you sure you want to go to an external site to donate a monetary value?
WARNING: Some countries laws may supersede the payment processors policy such as the GDPR and PayPal. While it is highly appreciated to donate, please check with your countries privacy and identity laws regarding privacy of information first. Use at your utmost discretion.
There have been a few Userscripts.org (USO) clones popping up. The only one that I am somewhat familiar with is from USO at http://userscripts-mirror.org/.
Any others I suggest being very careful especially if they advertise logins.
