ScriptSafe vs Noscript - difference?

Post by chromium1111110000a »

What is the difference between ScriptSafe on chrome / chromium and Noscript on Firefox?

I read that all script blocking addons on Chrome are basically useless because they are all easy to bypass... is this true?

Are there any plans to port Noscript to Chrome?

Interesting. So does the fact that you referenced those threads in 2016 mean that the situation still hasn't changed? (I see Giorgio still hasn't ported it, so I take that as one indication.)

Cool, thanks.

Btw, any idea what APIs things like ScriptSafe/NotScripts/ScriptNo use to detect and block script loading? I remember reading an early blog post talking about how Chrome didn't want to implement any synchronous APIs, which by definition would be what blocking APIs are. But with these NoScript pretenders and adblockers existing now, I assume they added some.

Nope. Try manually unpacking the extension and reading through its code.

Okay, worth asking, I figured!

I did google a bit and while I didn't find the whole story, here's an article suggesting NotScripts used a crazy hack to get around the initial lack of APIs for blocking requests. Sounds like they did something like adding fake entries to the cache to intercept script requests??
