I like this Add-on, it's easier to use than NoScript, and seems to block sooner in the add-on chain, relieving work on privacy screens and such, and it catches non-existant domain names from running scripts. (which is a particular problem I've been having lately … random invented domains which seem to run directly in memory without going out to the router)

@developers, I would like to use it *instead of* NoScript, but sadly I need to keep NoScript, because that lists the domains it blocked and allowed. I need that list to know what to add to the blacklist, and I don't get, even a log, from Script Blocker Ultimate. So I only know I've got my blacklist right for current threats because they don't show up in the NoScript list any more.

This add-on is very handy to keep random scripts from running on webpages like autoplaying videos with loud audio.

It works properly ... very interesting ... and magical remove the script which blocks paid content from newspaper and other sites... very surprised ... helped a lot

Does what it says, and quickly too!
(Though I'm not expert enough to verify the "doesn't track you" claim)
I can say however it is the best simple & lightweight javascript blocker out there.
I second the other reviewers suggestions for a one click option to enable or disable JS in a specific link, also the ability to white or blacklist links within a single domain. But then maybe it wouldn't be a a simple add-on anymore?
Keep up the good work!

easy to use, i like there some blackwhitelist, also allow some/all. very best

The addon for Java where the black / whitelist
- works
- is unusually effective (wildcards can left & right * .... *,
and works with any parts of the website URL

Just note: After inserting website URL *parts* (or complete), you have to click in the toolbar icon either
"Block all but whitelist" or "Allow all but blacklist.

literally the best fucking addon ever no cap. websites blocking you out because they detect your adblock? turn this extension on gets rid of that crap instantly, smart people use adblock; woke people use this. thanks for coming to my ted talk

There's a common scenario I encounter where I'm on a page and I know on that page there's a link I'm interested in opening with JavaScript disabled. However, the page I'm currently on requires JavaScript to function and display, so when I disable JavaScript, the page automatically reloads and I can no longer see the link I wanted to open. An option for disabling the automatic reload would be nice. There are roundabout ways for resolving this, such as copying the link beforehand (unless it's one of those script links that can't be right clicked and copied) or by first adding the domain to the whitelist and enabling the "Block All but Whitelist" option (a lot of unnecessary clicks). What would be awesome and something I've never seen in these kinds of add-ons is a right click context menu entry that allows one to open a specific link in a tab that has JavaScript disabled.

"Best in Performance, This addon does NOT track user activities same as others". That may be, and without doubt it's easy to use, yet I feel I don't have enough control. i.e. I don't see right away which URL(s) exactly will be allowed when whitelisting a domain and I don't see which URLs might possibly require whitelisting, too.

PS: You're right, you do deserve 5 stars - my problem is my problem ;-). The request blocker is enabled but my point is that I don't see, which URLs/requests are being blocked without going into options. Thus I can't "quickly" decide which ones to enable or diable. But I see that this Addon is just perfect for the average web user! You've earned the fifth star solely by this great and instant support.

GREAT !!!
Same like No Script but this Script Blocker Ultimate still support Firefox 52.9.0

بسیار عالی هست

First time user here, on Firefox in Windows 10. It seems pretty easy to use. I set it up to block all except whitelist (the default was to Allow All, perhaps there should be a warning first time this is used?). Anyway, I went to give a donation to the developer and it suitably blocked PayPal, until I whitelisted it. So yeah, looks like it's pretty handy! Is there also an android version?

Great!!!
I also have one question/feature request: Does it support regular expressions?
Some sites e.g. Ebay have multiple domains and all of them require JS. So I'd like to be able to allow something like: `.*ebay.*
