What is JShelter?
JShelter is a browser extension to give back control over what your browser is doing. A JavaScript-enabled web page can access much of the browser's functionality, with little control over this process available to the user: malicious websites can uniquely identify you through fingerprinting and use other tactics for tracking your activity. JShelter aims to improve the privacy and security of your web browsing.
How does it work?
Like a firewall that controls network connections, JShelter controls the APIs provided by the browser, restricting the data that they gather and send out to websites. JShelter adds a safety layer that allows the user to choose if a certain action should be forbidden on a site, or if it should be allowed with restrictions, such as reducing the precision of geolocation to the city area. This layer can also aid as a countermeasure against attacks targeting the browser, operating system or hardware.
Please see the FAQ (https://jshelter.org/faq/) and our blog (https://jshelter.org/blog/) for more information about the extension.

- (2023-08-03) Jacob Griffin: Pretty good extension. If you're a user that found NoScript to be a little too time consuming to get setup properly etc. I'd try this out. It's basically a "set it and forget it" form of NoScript that does all the blocking you need with no initial setup or tinkering, although you can still tinker AND there are plenty of settings to tinker with.
- (2023-05-14) Arioch The: Unusable black hole. In the first 2 hours of using (Vivaldi 5.6.2867.62 on Win7-x64): 1. Kills reCaptcha service (until JS Shield prohibited - the very essense of the extension) 2. Kills DisQus service (until JS Shield prohibited - the very essense of the extension) 3. The bug reports page can not be found from the main site 4. When finally found - it requests you to create new account (logging in with OpenID/OAuth through other sites? no, not in 21 century) just for the privileger of laying 1-2 bug reports 5. When you do - it denies to ackknowledge the already xreated and activated account and instead goes infinite circles through HTTP login screens. Well... if that is how they bug-fixing page "works" and if it is how the casual browsing becomes just after 2 hours with this "www-killer feature" you may extrapolate how it would go further...

- (2023-03-09) ••: It is causing high cpu and memory usage in some pages until freezing the system, both chrome and firefox and still not fixed. Could not recommend this extention with lot of bugs. https://pagure.io/JShelter/webextension/issues
- (2023-02-17) Bérenger Lieber: Does the job. BUT annoyingly breaks login and forms for websites using reCAPTCHA. Guess we can't have both.
- (2022-09-30) Sven: Very well made extension that actually works, I've tested it out on multiple sites. A big win for privacy. Thanks for all the work you do
- (2022-08-18) John D: Seems useful. Will stay with it for a little while to test.
- (2021-10-09) Art2007: Спасибо разработчикам. Конфиденциальность в наше время - роскошь.
- (2020-08-04) Breaks some websites with CAPTCHA checks to make sure you aren't a robot on some websites. CAPTCHA does not work if you whitelist the website in this programs settings you have to go into extensions and totally disable it from running in order for CAPTCHA check to show up. One website I can for sure confirm is not working is:https://www.warframe.com/ under this area when trying to login to account via this area within the site: https://www.warframe.com/robot-check
- (2020-03-12) EWEB TV CHANNEL: Un estensione davvero incredibile! Quello che cercavo. Funziona veramente. Blocca effettivamente i popup in javascript sito per sito. Anche la precedente che avevo bloccava effetrivamente i js ma poi era diventata fastidiosa per il sito che volevo bloccare bloccando però tutti il mondo, li dovevo mettere in whitelist. Questa invece...è perfetta ho impostato: non blocco tutto il mondo però blocco gli js solo un sito. Tornando all'estensione..questa....ha una grafica di semplice, facile e immediato utilizzo. Un enorme grazie.
- (2019-07-22) Martin Bednář: Not only great idea, but the extension is already working. I appreciate friendly graphical user interface - it easy to understand setting of this extension. The best idea is testing page (https://polcak.github.io/jsrestrictor/test/test.html), where I could immediately try that extension works perfectly - it has hided my sensitive information that may have been misused by potential attackers on the website. Now I feel safer.

- (2022-11-26, v:0.11.1) Adam: Does it protects against malvertising, tech support scams?...
Malvertising is one of the common ways unsuspecting users may encounter when surfing the internet. There are recent news that a trojan was pretending to be GIMP, even managed to fake the display URL. Tech support scams is one of the many ways users can run into when opening an ad landing page. Websites of these oftentimes lock the user's browser (model windows to prevent closing browser or back button, contextmenu disabled other methods of escaping, etc.) - (2021-10-05, v:0.5) Pedro Gomes: same here in Chrome
same here in Chrome - (2021-10-03, v:0.5) Feren: popup display error
When I click on the extension icon, the width of the popup window is only like 30px width. Here is the image: https://i.imgur.com/KrEsluJ.png I'm using ungoogled-chromium on windows 7. I'm not complaining i'm just trying to help make the extension more compatible by letting you know my issue. Thanks.
