For a while now, I've had userscripts set up to do various things for browsing. I believe I used to use Greasemonkey, but I was told it was bad in some way and started using Scriptish. However, when the new layout came out, my userscript to constantly use Earth Day version of YouTube broke. I was used to the black background on YouTube, so I went to find another one. However, the only supported dark YouTube userscript was for Stylish, so I had to download that. Then recently, the Show Tags userscript I had for Scriptish so I could see YouTube tags broke. I discovered it updated in a way that only works in Greasemonkey.
Long story short, I now have Scriptish, Stylish, and Greasemonkey all on at the same time I have various userscript which only work for specific ones. I seriously do not like running this many different kind at once, and I'm sure that's bad for the browser in some way. Any suggestions on how to rearrange this stuff? What to use? I believe I could move everything but the Stylish script into Greasemonkey, but I still can't remember what was wrong with it and don't want to risk it.
