Reviews for User-Agent Switcher and Manager
User-Agent Switcher and Manager by Ray
Review by Korwin
Rated 4 out of 5
by Korwin, 2 years agoIt works regularly in Mozilla Firefox 129.0B9 X64. It is a pity that manual editing of a list of comparison of domains and UA is carried out only in JSON format, and not in something more accessible to non-specialists.
Upd. 0.6.6 (Oct 8, 2025) and Mozilla Firefox 148.0b12:
1. Selected "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/142.0.0.0 Safari/537.36" from the list.
2. Clicked "Apply (all tabs)".
3. Clicked "Test UA".
4. webbrowsertools.com: "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:148.0) Gecko/20100101 Firefox/148.0".
The extension does not perform its main function.

- Rated 1 out of 5by Cr, 8 days agoThis extension is unbelievably user-hostile. I’m convinced the developer has some deep resentment toward anyone who isn’t a programmer. I genuinely can’t understand how something this frustrating to use ended up being officially recommended by Firefox. Now I finally understand why Firefox keeps losing market share. If I had the option, I wouldn’t even give it a single star.

- Rated 5 out of 5by Firefox user 19519608, 14 days agoCurrently it works fine. Don't know why people reported different 4 months ago.
It does cause issues: Youtube subtitles can't be displayed, Claude uploads are getting rejected. - Rated 5 out of 5by aber, 14 days ago

- Rated 5 out of 5by Firefox user 16549430, 6 months agoThis has so far not caused the dreaded Cloudfare veryifying loop that the agent switcher by ntninja does. I thought Cloudfare was just completely against agent switchers until I tried this one instead.
