Smoothly works on Chrome, but not works on Safari

The Tampermonkey displays the script is enabled and working on, but there's no button on the likers' page.
Mac OS version: 10.15.4
Tampermonkey version: 4.10.6108 (from Mac App Store)

It also not works on Firefox with same situation.
Firefox version: 74.0

It works with Greasemonkey on Firefox 74.0, macOS Catalina 10.15.3.
However, using the same browser and OS with Tampermonkey, I could not even alert or log anything on the console. I'm trying to figure out what the problem is.

For now, you can just use Chrome or use Greasemonkey with Firefox on macOS.

Yes, that's a weird issue, and I just confirmed it's worked with Greasemonkey. Anyway, thank you for your time and your life-saving script.

It turns out that this problem is caused by some CSP policies on Twitter. Tampermonkey just does not work on Twitter with Firefox.
So in all, if you want to use this userscript on Firefox, you'd better choose Greasemonkey instead of Tampermonkey. But if you do insist on Tampermonkey with Firefox, you have to turn security.csp.enalbe to false to make it work on Twitter.
You can refer to this comment for details.

Finally! Tampermonkey's update v4.11.6114 fixed this problem!
Now you can keep csp true by default and use Tampermonkey at twitter.com~
