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.
