Review summary

Reviewers largely report two positives: the add-on can noticeably speed up some sites and is easy to use, with strong flexibility for power users. The top recurring drawbacks are Cloudflare/anti-bot verification loops and reliability problems where the extension may not work consistently.
Pros
  • Significant performance improvements on certain sites (e.g., Google Maps, YouTube) when using the switcher.
  • Easy to use and generally does what it advertises, with straightforward setup.
  • Highly flexible and powerful for advanced users, offering a wide range of user-agent options.
Cons
  • Cloudflare CAPTCHA/verification loops triggered on many sites when spoofing the user agent.
  • Reliability issues; some reviewers report that it doesn’t work or breaks site functionality.

2026-08-04 ***** ID options are outdated browser versions, thus, addon does not work for sites with sensitive "unsupported browser" settings, meaning certain sites will block you. Either 1. offer up-to-date ID options 2. enable easy "toggle off" or "whitelist" option so I don't have to keep disabling the addon every single time I need to log in to such an abovementioned website.
