by x3m_ff_usr, 10 months agoUsed 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.

- Rated 5 out of 5by Firefox user 19519608, 6 days agoCurrently it works fine. Don't know why people reported different 4 months ago.
It does cause issues: Youtube subtitles can't be displayed, Claude uploads are getting rejected. - Rated 5 out of 5by aber, 6 days ago

- Rated 5 out of 5by Firefox user 16549430, 6 months agoThis has so far not caused the dreaded Cloudfare veryifying loop that the agent switcher by ntninja does. I thought Cloudfare was just completely against agent switchers until I tried this one instead.
