Recently switched to Violentmonkey as it is a userscript extension that is open source and kept up to date. Working great so far with my existing userscripts I imported with the import feature. Had been using Greasemonkey until now but that hasn't been updated in 3 years so started to experience issues, and won't consider using Tampermonkey as it's closed source.

开源就是正义

与tempermonkey比兼容性稍有不足，但是开源且易用性更好

Efficient and simple to use.

很棒
