worked great for a while, but unfortunately the white list mode broke on the latest version.

It seems that rolling back to the previous version could make it work again.

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!

Used to work great, until the latest update (v0.6.5.1)

I’ve been using this extension for a while and it worked flawlessly up until version 0.5.0. Unfortunately, after updating to version 0.6.5.1, it completely stopped working for me, user agents no longer apply as expected, which defeats the purpose of the tool.

Thankfully, Firefox allows users to install older versions of extensions. If you’re experiencing the same issue, you can roll back to a previous version here: addons.mozilla.org/nl/firefox/addon/user-agent-string-switcher/versions

Hopefully, the developer can resolve the problems introduced in the latest release. Until then, version 0.5.0 remains the most stable choice.

Amazing open source extension, thank you for your work

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 used to work very well, but recently it didn't work, I was frustrated, I didn't know why, I tried whitelist and blacklist mode, it didn't work, I was using the latest version of firefox, not sure if it was a compatibility issue with the latest version

This addon has taught me that nearly all web sites that supposedly aren't compatible with Firefox actually are compatible. I use this at work, on my android phone, and on my home PC as well. It's an essential addon, in my opinion, and I've had nothing but success.

Its great

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
