Something weird started happening recently, the extension just hangs and I'm unable to open websites. Debug info of the addon repeats this line

Uncaught (in promise) Error: Could not establish connection. Receiving end does not exist.
send moz-extension://0bdccd93-3bcd-40de-8763-8dcb82ab7603/nscl/common/Messages.js:66

The only way to fix this is to restart firefox. Disabling and enabling extension doesn't work (I could disable noscript and websites would start working, but then I'd have lots of scrips left unblocked).

Like the reviewer VoxPop I too began to have issues with this extension - which I have used for several years - quite recently. It appears to be related to Firefox Sync as whitelisted domains disappear after I have used another PC upon returning to my main machine.

It has been an excellent, if occasionally labour intensive, addition to my online security but as of writing it frustrates as much as it protects.

Funziona fin troppo bene. Di conseguenza, in una navigazione normale da "padre di famiglia" la maggior parte dei siti non funzionano in parte o del tutto, rendendo necessario disattivare e riattivare NoScript secondo necessità e con frequenza, compromettendo navigazione e appagamento.
Purtroppo sicurezza e soddisfasfazione sono due obiettivi non convergenti. Bisogna scegliere quale dei due è prioritario.
In ogni caso ringrazio Giorgio Maone per il suo ottimo lavoro.

Had to stop using and switch to another script blocker due to it crashing on Fidelity Investments website.

Downloadable blacklist needed.

Lately when I look in the trusted list there are about 40 websites marked as trusted like: google-yahoo-hotmail etc...............I have not added these to the trusted list. So who put these websites in this list? Uninstall noscript and install again same problem. Cannot remove these sites, meaning I don't know how to. So untrusted by hand. What is this, some malware/adware?

previously remembered permissions. but now no longer . so frustrating to have to allow trusted sites every time
is this a known issue
will it be fixed in future update

a script that is marked "trusted" on one page, is also trusted on every other page, which is the same as "trusted globally".

if "disable restrictions globally (dangerous)" is
"dangerous" (in the programmers opinion), why is the "trusted" not bound to the specific page?

- page A does work without script X
- page B doesn't work without script X
(e.g. doubleclick, googleanalytics, googlestatics)

why would i want to allow script X on page A?

Fantastic in theory, and often in use, BUT one major issue for me. It takes time to allow each part of each site that you "trust". When your work requires you to interact with a lot of web sites, that adds up. All good, EXCEPT that on a regular basis, NoScript simply "loses" those entries. My sites stop working, and I have to go in a do it again for each. Remember too that it's not a matter of "trust this site", as a great many have good and bad mixed together. I personally go to at least dozens of sites that involve 5-15 different scripting sites, and have to sort out on each which are good and which are necessary to get the data I need. So it's a lot of work, but worth it, as long as my work isn't randomly discarded. Fix this, it's 5 stars. With the problem, it's closer to a "necessary evil".

Another user (mdontu) just detailed the same problem I have.

Usually this extension is absolutely great. I've been using it for years. However, for quite some time it seems to struggle with resetting large whitelists when Firefox is sync'd over multiple computers. Gets really frustrating when you have to re-whitelist sites that you know you have already whitelisted.

The problem seems to be getting worse. I think the developer may be aware of it, but this really should get addressed.

Très bien jusqu'à maintenant mais depuis la dernière mise à jour automatique : j'ai perdu tout le paramétrage constitué avec soin depuis des années.... Or le module ne permet pas à ma connaissance d'en faire une sauvegarde. Vu la complexité des sites et les tâtonnements nécessaires pour savoir ce qui doit être autorisé ou non, c'est un défaut majeur.

Something went off this past week. Either with Firefox or the extension. I use Firefox Account on three separate computers, one of which I had to reinstall a few times. Now my list of trusted sites gets reset periodically (every few hours?). The rest of extensions seem do be doing fine, though, including the Multi-Account Containers which I know it uses the Firefox account to synchronize across installations.

このアドオンが有効だと、ファイルのダウンロードができなくなります。

安全なのはいいですが、いちいち許可しなくてはならず、面倒ですね。

ほかにも、ページが正常に表示されなくなったり...

これは、ほんとにセキュリティを重視する人や、危険そうなサイトに接続したいとき向けのアドオンです。
普通に快適なブラウジングをしたい人にはお勧めできません。

安全なのはすごい安全です。

I installed Noscript yesterday and am trying it out, but I'm about to un-install it because it breaks the two websites I use the most -- www.flickr.com and familysearch.org, even though I've put those addresses in the per-site permissions list.

flickr.com -- while the photos display, they are no longer selectable. Also, the statistics page no longer shows the usual graphs, etc. Also, the page width detection is now broken, so the photos are displayed as if they are on a narrow device instead of a desktop computer.

familysearch.org -- the main menu text and wrap-around stuff is displayed but there is no list of genealogy collections to select.

https://www.bbc.co.uk/ -- images on video thumbnails show the BBC logo on a grey background rather than the thumbnail image.

This is very useful tool but it breaks a lot of sites, like:-
speedtest.net , discordapp.com, tribesnext.com, turkeh.net, tribesrevengeance.net.
Summary: It blocks some functions and some Data and hides some buttons.

Really have the latest user interface. Earlier I could manage blocking specific scripts in a few clicks now it's buggy and totally charged
