Pessima su Android!

It literally doesn't work most of the time. Sometimes it randomly does, but mostly it just doesn't do anthing

Doesn't work anymore.

current version of 0.6.6 December 17, 2025 is broken on firefox 145.0.1. user-agent is not taking effect and noticed an error in debug-addon of firefox.
Reading manifest: Warning processing storage: An unexpected property was found in the WebExtension manifest.

Stopped working. This is now absolutely useless, and no update seems to be forthcoming.

Does not function

This addon breaks youtube. After around 30 sec of playback the player stops and says "something went wrong"

Does not work anymore..

This addon was great untill Per-container UAs stopped working! Pls Fix!!!

This is a badly behaving extension that is breaking youtube video playback and google search, causing google to constantly spam captchas everytime I try to use the search engine. I do not recommend installing this!

The extension used to work fine, until a recent update. Per-container UAs stopped working... Or in fact, the extension as a whole stopped working at all. No changes would make it work again.

🔹It worked well before the new update. 🔹After the new update, all of the multi- account container becomes sharing the same user agent. 🔹I am using portable firefox with multi-ac containers for nearly 3 to 4 years. 🔹After update the new version of user-agent switcher and manager, 🔹all of the containers share the same user agent and cannot set different user agents for each container alternately.

It doesn't work.

This doesn't work. I have to manually change the user agent on every startup or time interval. I don't need a data thieving, resource wasting, pretend add-on for that. There is a "Random User-Agent (Switcher)" that works perfectly and is very simple to set up.

cloudflare captcha + youtube are broken with

turns out this extension is injecting scripts into pages, and breaks all cloudflare protected sites

Unfortunately I have discovered that the current version of this add-on triggers the Cloudflare 'Captcha of Death' denying access to hundreds of web-sites and as such I have deactivated it.

Super confusing interface. Choosing different user agents causes them to be smooshed onto the default user agent. Doesn't appear to actually work consistently at all.

It was last updated 2 years ago; looks like abandonware.

where is [Apply only this 'website.com' ] ??

not every one wants to use container??

so unusable....

you couldn't have made it any more confusing. i have no idea how to use this shit. this is so sad, i wish user interfaces were real.
