NoScript

Works well at what it does. If you are using Firefox, it's fairly unnecessary, because uBlock Origins already does everything this does basically, while also have robust anti-advertising and being able to fine-tune elements allowed simply.

That being said, NoScript is what is trusted by the Tor project. It is the only extension that comes pre-equipped in the Tor Browser, and the only one they recommend using.

And if you aren't using Firefox or other non-Chromium, the functionality of uBlock is becoming very limited (thanks Google) due to Manifest v3 (people are having to switch over to uBlock lite).

NoScript is great browser protection and If I could convince everyone to use it I would. But there's one downside, and that is that casual computer users are often befuddled by NoScript. Nevertheless, once you understand it, it can be an excellent help with security.

This is an add-on is something anyone should use before they open the browser to surf the web.

It protects your "trust boundaries" against cross-site scripting attacks (XSS), cross-zone DNS rebinding / CSRF attacks (router hacking), and Clickjacking attempts, thanks to its unique ClearClick technology.

I find NoScript to be an absolute necessity. That said, it's not for the faint of heart, whether it's twiddling with what it's going to take to get a site to work sometimes, or having your mind blown to smithereens by just HOW MUCH intrusive cross site scripting there is on some popular websites.

If security is your biggest concern, NoScript is a good add-on. You can set it to allow or deny websites access to your computer as you see fit.

The downside is that it is in no way convenient. You have to manually white list basically every website when you first try to access them. There can be half a dozen web address choices (or more) that come up and some of them could be necessary for functions of the website to work properly or they could be crap that you actually want to block. The domain names may be helpful in deciding which are which, but there isn't always a way of knowing which ones to white list or deny without some trial and error.

I used NoScript for a good while, but finally got tired of messing with it whenever I visited a new website, so I removed it. It just wasn't worth the aggravation to me.

Makes you aware of what websites are doing and to disable their excesses.
