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.

Not working. Have watched the YT video and have tested both the white list and i've tried to use it on ALL websites and it isn't doing anything.

Useless. Whitelist doesn't work. If I put YouTube in the Whitelist, and set the add-on to use Whitelist, the icon is still off when using YouTube. It seems to maybe help when manually turning it on, but ain't no body got time fo that.

Abandonware

Doesn't work

Absolute trash addon, could not do the one thing I asked it to do which was TO CHANGE MY USER AGENT FOR A SINGLE WEBPAGE

Doesn't work anymore, no updates in sight to fix this.

I recently started testing this extension. The last version "improved" the extension so much that it stopped working. It doesn't matter what user-agent it shows - browser tests always return the original one.
