posted 6 years agoThank you for your review! The “huge cache of hundreds (!!!) of files […], which may be completely removed” are in fact used to generate sensible values for the `navigator.*` browser identification values. Parsing information like operating system, CPU type, device type, … is not a simple affair as there are no standards at all – one just has to guess based on the COMMENT parts of the User-Agent string. Fortunately the BrowsCap project has maintained a list of matching patterns for figuring out this information since 1997 that is extremely reliable. As such, I will continue using it even if it means bloating the extension size by about 3MiB. The fact that it allows everything to just work out-of-the-box with just a single input value (the User-Agent string itself) definitely outweighs that, by comparison small, price.
I would like to think that, if you don't need this complete level of emulation, then you may use just about any of the other User-Agent switching extensions because – to my knowledge this capability is unique to this extension.

- Rated 2 out of 5by Xenofox, 2 days agoI use this extension for many years now. But sadly the development is very slow. It's very outdated, you're stuck with very old and on many websites not anymore supported browser-versions to choose from like Firefox 134, Firefox 128 ESR, Safari 17, Edge 131. Also no matter which browser you choose from, on browserleaks.com/javascript its still possible to see that mozilla is used (the parameter appCodeName shows "Mozilla". So Mister ntninja update the extension please!

- Rated 3 out of 5by Nocturne, 3 months agodoesnt keep itself isolated using "only for this site" pref. Apparently it enables selected UA for *all* sites, and for ones you didn't want you have to opt-out... Not best UX

- Rated 1 out of 5by Adrien, 4 months agoPlante instantanément Firefox mobile.
Instantly crashes Firefox mobile. - Rated 3 out of 5by Synetech, 4 months agoThis used to be the most functional useragent-switcher (even if the UI/UX was left wanting), but even this doesn't seem to work anymore. 😕
- Rated 4 out of 5by Firefox user 14946084, 4 months agoAlthough this extension doesn't solve my issue completely (hating how Facebook looks and works), I am able to easily convince FB that my laptop is a mobile device which makes it more tolerable.

- Rated 5 out of 5by WhoAboutYT, 5 months agoI love it, I use the user-agent switcher because sites like Roblox believe firefox is "suspicious" and will serve you 10 Captchas if you are on Firefox
- Rated 1 out of 5by Yeko, 5 months agoDoes not work at all. Sites still see my browser's original version string.
