Excellent Rated 5 out of 5 stars

This addon works perfectly to fix youtube's ridiculous changes. First I was able to move the top search element, which is just another annoying toolbar that cuts into viewing space down to the bottom of the page. Then I pushed in the video screen that was needlessly hugging the border.

It's obvious that Google's webmasters have too much time on their hands but once again a Firefox addon restores the site's tolerability.

Awesome Addon, good job!

I found one negative thing:
It doesn't work when another Firefox Window is open at the same time.

Very good extension. However, how on earth can you do something like modify the <p> tag for the entire page's contents? If I do tag=p pos=5 I only get one item to edit. If I take out the pos=5 (ie ALL p tags) I get "expression has non-unique result" and I can't save. Need to be able to globally change eg font for all <p>, color for all <a> etc. Tips?

A must-have for people using white-on-black themes and inverted high-contrast themes! Thank you so much for this great add-on! It works much better than editing userContent.css, especially since actions/styles can be applied after Javascript induced page changes. Wonderful!

One of the best extensions ever made.
CYW helps you to modify ANY web page, automatically, and with a low programming knowledge needed.
Great Support: the extension is now again compatible with FF 20+. This guy deserves all our support.
CYW is absolutely inside my personal top-3 list of the best FF extensions ever created.
Simply amazing.

Certainly one of the most useful addons around. Easier than Platypus, as powerful as Greasemonkey - All in all, it's just about perfect!

Fellow Linux users: Ignore the 'not available for your platform' label - It works perfectly fine under Linux.

Why not on linux?! Rated 3 out of 5 stars

..I love this extension, but since I seldom use Windows anymore its very unfortunate it doesn't run on my main Linux OS for whatever the reason.

This power to the user should be in every browser by default!

I can see there is a lot of work in this extension, very much attention to details.

Thank You!
Please continue the development!

Potentially powerful extension let down too badly by lack of document/support - unusable by newcomers except simplest cases. Rated 1 out of 5 stars

Hopeless, just hopeless.

Tried to set up a script to modify the headers of a page on loading. Tried to select HTML container and got an error that it didn't match the URL. Why not? No idea. Help pages? Can't find them. Guidance on modifying elements that can't be pointed at by the mouse (eg hidden elements, headers, etc) - none.

I haven't tested it further, it doesn't let me edit pages except the parts that can be seen, and the help is non-existent except for the most obvious parts that don't need help anyway.

It's a nice tool but it'd be better if the script could start before page loading and not while loading beacuse it slow down the load of the page. Like Adblock Plus and other do.

Very useful, simple and easy to use. Was modifying pages right after it was installed, no tutorials needed. Plus supports the newest beta builds of Firefox, which is a big plus!
