There was an issue on Linux several months back that seemed to ignore some of the agent settings, but this appears to have been fixed. Thank you! Recommended, great extension.

So far it is working well. Thanks a lot! Finally i am out of request desktop site hell.

Per-window User-Agent is nice. It'd better if it were persistent beyond Firefox restarts. Currently I have to set the user-agent for a window after Firefox started.

This helps a lot can download things you normally can't access sites also thanks man
