是否可以将 javascript 注入 Twitter 提要以自定义其颜色、字体等？

Question

是否可以创建一个 safari 扩展程序来注入 javascript，一旦它加载到屏幕上，就会改变 twitter 提要颜色、字体等，或者 twitter 以某种方式禁用了它？

Answer 1

Twitter cannot "somehow disable" that; if you inject Javascript/CSS into a page via an extension you can do whatever you want.

Answer 2

Yep. You can use Greasemonkey (for Firefox) or Tampermonkey (for Google Chrome) to create userscripts which are Javascript scripts that are executed on the pages that you specify.

• Here's a similar userscript I wrote for facebook: customizefb
• Here's one I wrote for StackOverflow: Who downvoted me?!
• And here are a bunch other people have already written for twitter .

You can always run custom Javascript directly from the browser console too if you don't want to install the userscript plugin.
