No, it isn't. uMatrix is a replacement only for the shallowest feature of NoScript. There's a ton of stuff that classic NoScript does that nothing else provides (including the new WebExtensions NoScript, so far).
Agreed, I plan to remove this. See: https://github.com/gorhill/uMatrix/issues/771#issuecomment-2...
NoScript classic has a lot of functionality that helps you keep sites usable when scripts are blocked, or to help you stay secure when you have to allow some scripts. Some of the latter features are protections that will occasionally get in the way of sites that are fucked up in non-malicious ways, but that doesn't make them misfeatures. In my experience, the only XSS filter false positive has been Wolfram Alpha, and I've only encountered the clickjacking protection with advertisements that are getting in the way of the content I'm trying to interact with.
Sounds good, but have you looked at the code behind this? The XSS filter is the same way – a giant mess that only protects against the most trivial of XSS anyway.
I forgot about its clickjacking feature, though. You’re right, that one is valuable.
edit: I see it's there. Released yesterday. Yay! Now if only Firefox could add a "Add to desktop" option, I could really switch!
Can't do that with UMatrix.
FYI you can actually use both NoScript and UMatrix at the same time.
NoScript ("allow first-party scripts" and block everything in "Embeddings" tab) + FlashBlock seem to be the only way to block all autoplaying crap in Firefox for me.
You can also add uMatrix, uBlock & RequestPolicy and surprisingly they don't conflict with each other!
