Sometimes for testing or troubleshooting, you want to see if a site would work if you changed the user agent eg. Chrome.
This specific website soft-blocks Firefox, but works fine if you set the UA to Chrome: https://england.nhs.attendanywhere.com/
Unless I'm missing something - in Firefox you have to manually type in/edit the User Agent string, or use one of the baked in device profiles:
There's some annoyances with this:
Chrome/Edge makes this much easier:
This would be handy in Firefox and would also save having to install a UA-switcher add-on.
Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.
Please report broken sites to Webcompat.com . There's already a report about that specific site: england.nhs.attendanywhere.com - Firefox is an unsupported browser.
Telling users to spoof their User-Agent string is a bad idea. This makes it look like Firefox has even fewer users than it does, which just encourages more sites to stop supporting it.
Nice idea, thank you for posting!
I created a report, so it isn't forgotten here.
