Tampermonkey is pretty good, it's my preferred userscript extension. My only problem with it is that it doesn't work with Firefox containers. Specifically, trying to export the settings to Google/OneDrive/etc. won't work if those sites are set to open in a container; when it opens auth.tampermonkey.net/auth to use OAuth to log into those services, the pages open in the specified Firefox container and Tampermonkey immediately throws an error. I've tried opening TM in the same container, I've tried setting auth.tampermonkey.net/auth to always open in the container, etc. but nothing works. The only option is to export to a ZIP file and carry that file to the destination system. 😕

挺好的

Very useful UserJS, not like FireMonkey..

I love the flexibility of this. The only downside is that Opera GX decided to blacklist this but that's on them. Basically what this does to my understanding is it edits the webpages that you visit not by itself but by using third party scripts that you install. you can find these on greasyfork or other trusted sites. Beware if this has been installed maliciously or randomly as Opera GX claims. But the same could be said about any other extension so don't expect it to hold any water.

Need UserStyle ability like FireMonkey

最好用的浏览器扩展，没有之一
