__________________________________
Quick JavaScript Switcher is a useful tool for web developers to test site behavior without JavaScript and ensure graceful degradation. SEO specialists can simulate how non-JavaScript search engines view a page, helping identify indexing issues. It’s also valuable for privacy-focused users and accessibility testers to assess a site’s functionality without JavaScript, and for quickly comparing page load speeds with and without dynamic elements.
Works with any URL scheme, including domains, subdomains, IP addresses, localhost, and local .html files!
Note: The Pause/Resume feature has been temporary disabled since 2.1 because too many users complained about the required 'debugger' permission.
__________________________________
Works with Chrome 88+
(for Chrome <88, use the v1 version)
Permissions:
A detailed topic about why QJS need them (TLDR: didn't have choice for good UX):

Troubleshooting with v2:
Some users experience issues with the v2 update, which can often be resolved by uninstalling and reinstalling the extension. I apologize for this inconvenience.

- It's nice to be able to disable JS on one site and leave it functional on another. Works good!
- Patrick Boatner
- Really solid. I hope you can release another version that includes the Pause/Resume feature with the debugger permission. I find that very useful, like on news sites that need JS to load the images, and then slowly do intrusive things with JS. Pausing the JS after the page has loaded allows you to view all the images with the article, but kills all the other junk on the page.

- Doesnt work...

- This seems to be broken in the latest chrome update.

- Quick JavaScript Switcher has been a game-changer for optimizing my website's performance! By easily toggling JavaScript on and off, I was able to identify and streamline areas that impacted loading times and overall user experience. It played a key role in enhancing the efficiency of my site. Check out the results at https://www.wingreserve.com/

- I've been using this extension for years, and love it. It does exactly what it says it does. No more, no less, no nonsense.
- Rahul S.
- Awesome!! Works great and per site.
- Bruce Li
- I am glad to hear about the release of the long-developed version 2.0, although there appear to be some bugs at first. I don't mind waiting a while because the major change is going to be beneficial for the years to come. I have been using this almost every day since 2018. It definitely adds value to my web browsing experience. I just made a donation.
- Tony H
- It does what it is supposed to do with ease! I've been using it for years as a simple way to toggle Javascript off and on. --> If it doesn't work with the new update, follow the developer's instructions to remove it and then reinstall it.
- Антон Евстигнеев
- Great tool. For those who has icon bug - just reinstall the extension, this fixed the issue for me.
- Ralph Capper
- I'm sure this used to toggle on/off without refreshing the page, but now it trigegrs a refresh and is completely pointless for development purposes.

- This used to be one of my favorite extensions, worked great. However the new update has problems and is never really clear if JS is on or off.

- It's been great for years, but now the toggle doesn't work. Chrome 130.0.6723.58 (Official Build) (x86_64), MacOS 14.7
- Shaunna H (ItsMeShaunna)
- changing the icon was a bad idea. it's so small i can't tell if it's toggled on or off and the colors are too light to easily distinguish. also it stopped working altogether until i uninstalled/reinstalled, which i only figured out to do by reading the reviews here.
- Chris Summers
- Worked fine for the past 2 years but whatever upgrade must have happened made it not work. I go to a news site I have gone to in the past and hit their paywall. I try to click the switch in the extension and nothing happens, paywall still there.
- S. Owais Ahmad
- Has been amazing for me. I did notice that it had stopped working on / around Nov 5, 2024 - but followed the developer's suggestion of uninstalling and reinstalling and it's back to the way it was!
- Lucas Lourenço
- Today it stopped working
- Nick Gallinelli
- Used to be great and now it doesn't toggle anymore.
- Christopher Boyd
- For years, it worked flawlessly. New update does not toggle (stuck in whatever state a site was left in) and prompts for donations.
- Firm Hand
- New version won't toggle to red. The old version was great!
- Ryan McCurdy
- I use this daily which makes this one of my top Chrome extensions. It works great and I would recommend!
- RJ
- New version seems broken. Unable to toggle javascript back on. There are no entries for the site with issues.
- Qasim Abdullah
- I use it to counter the "Disable Adblock to read content" websites, simply turn off JavaScript for that site, and that's it, you don't need to disable Adblock, this is the first ever extension that I've bothered to rate and leave a review. Good job! Edit: Changed rating from 5 stars to 1 star looking at the updated permission requirement. Unacceptable.

- Simon Ward
- Ive used this for years and it's been great but we need a better explanation of these permissions changes before I will re-enable.
- shishal singh
- I enjoyed this extension till now but starting today I am keeping it disabled until there is a very good explanation why it need these permission. -Read and change all your data on all websites -Access the page debugger backend
- Ralph Mason
- I've loved this extension for years, but the new update is not working for me. Once JS is turned off on a site, I can't turn it back on again. Using Brave and version 2.01.
- NFG man
- Simple and effective.
- Allen Walker
- Sry the new version as of 20 Oct 2024 have bug. I can't switch on but yes I can switch off.
- Merennulli
- Seemed great, suddenly stopped keeping track of which tab it's on with Chrome 124.0.6367.208 and there is no way to edit it manually (the list can be viewed in Extension Options, but there is no way to save changes made to the list). Even closing all other tabs, it picks a recently closed tab instead of the sole remaining tab that the Quick Javascript Switch button is clicked on. While the tab tracking problem may be a Chrome update introduced issue, the design decision not to be able to save changes in the Extension Options is problematic.

- works well but it seems to inject an invisible div by id "sukan" on every page, and I can't figure out why, or how it's doing it by looking at the source code, which sketches me out a bit.

- Does what it claims it does but you have to disable JS for each domain seperatly with no way of chancing that behavior

- Es magnífica. Me ayuda a evitar las molestias que producen tantas webs que inhabilitan el botón derecho o sobreponen advertencias para deshabilitar los bloqueadores de publicidad. Y en las webs en las que Javascript es absolutamente necesario, basta con no activar la extensión. Funciona perfectamente tanto en Windows como en Mac. Es un auténtico salvavidas. La recomiendo 100 %.

- Does what it says, nice and easy.
