Usually works really good. Might break some pages (like YouTube), but it's easy to disable it temporarily if it does. I have one problem with it though, the settings for what browser to spoof isn't saved. I clean out everything when exiting the browser, and somehow this revert the changes back to defaults (to Chrome). Not sure how the settings are saved, but they are lost every time i exit.

Also, an option to change the agent on every reload (instead of just after X mins) would be nice.

[EDIT] Got the settings to be saved by disabling Sync extension settings between browsers. Just a tip if other experience the save problem. The error occurs if you also purging the browser data on exit.

keep developing , good

this is the best user-agent addon.
it has all the features you need.
best of all it is well put together and incredibly smooth.

good product

Somehow this addon will cause Twitter's input box stop working (can not cut or paste).

Firefox 60.0.1 64Bit
Windows 10 Pro 64bit

Klein und funktioniert top! Einstellungen sind ebenfalls top! Vielen Dank!

Does the job well and the best random user agent switcher I found so far. Consider adding Chrome for Android so that there can be a few versions (latest and some early versions of chrome for mobile) of that user agent, the more the better. Consider keeping the user agents updated and more randomized from time to time so that websites do not blacklist certain user-agents. Overall I see great potential in your add on and hope you keep it updated for a long time and keep it growing with functions.

Great job -- minimal and effective. Thank you for developing this.

Works great! You need to add user agents for several Android browsers, everything else works fine.

Works as expected, easy to use: install and forget. Been using it for months, don't plan to stop using it.

a list with regex->specific UA could be a good addition

Работает без проблем , хотелось бы более расширенные функции , к примеру , как у Random agent spoofer.

It works great

De loin, d'après mes tests, la meilleure extension de gestion de l'en-tête anonymisé User-Agent, qui est absolument nécessaire pour un peu de vie privée.
J'ai également sollicité le support sur un problème étrange, qui s'est avéré ne pas provenir de l'extension, mais de ma configuration pré-existante. J'ai reçu des réponses très pertinentes en très peu de temps et ai pu régler mon problème.
