Chrome's Stylebot allows you to right click any item in the page, and automatically create a CSS rule for that element. I'd like to have the same for Firefox.

I've tried Stylish, but it adds so many annoying steps, since I have to "Inspect Element" with the default inspector, then figure it out how to call it in the CSS, then in the CSS fill everything manually …

Look at a couple of Stylebot screenshot to get an idea:

contextual menu

edit stuff live

It allows you to edit stuff live and see the preview while you're editing.

It doesn't have to have all the fancy visual options as Stylebot, it's fine as long as it lets me right click an element and have that element's name be pre-filled in the CSS: if then I have to manually set the CSS property, it's fine – assuming it previews them on-the-fly.

Now, I'm pretty sure there's nothing like that or I would have found it, but asking might bring unexpected results, and in future there might be an answer.

I want to keep the changes between reloads, so just modifying the CSS in Inspect Element is not sufficient.

  • In addition to Color That Site!, take a look at User Style Manager, which may have fewer steps than Stylish once you set it up. But it currently does not include functionality to select an element & automatically create a CSS template from it. You can use it in conjunction with Element Inspector & DOM Inspector to get closer to what you want, but not quite. You would have to use copy and paste. Commented Jun 7, 2015 at 19:26

  • @AngeloFuchs I could never have guessed that being persistent wasn't an obvious feature.

Color That Site! is quite good: not as complete as Stylebot, since its only goal is dealing with colours, but since that was the primary reason I using Stylebot anyway, that's good.

Actually, as far as changing the colours, is even more feature-rich than Stylebot.

    Could you add a screenshot and elaborate a bit more on what it can do and what it can't? Commented Aug 7, 2015 at 7:46
