Firefox on my laptop redirects linkedin.com to linkedin.cn

Hi

If you clear your browsing history in Firefox, does that website address redirect correctly?

clearing all history would be very inconvenient :-/ I removed all instances of linkedin from the history - they were all linkedin.com, there simply was nothing about linkedin.cn o.O and it didn't work, it still redirects to linkedin.cn I just verified on my other PC, works fine

Are you using a different DNS server for Firefox and for "Web"?

Does "Web" incorporate a proxy/VPN, which may be allowing it to avoid the redirect?

>>"I just verified on my other PC, works fine" Using what browser?

>>"Does "Web" incorporate a proxy/VPN, which may be allowing it to avoid the redirect?" Can't verify, it crashes when I try to check the settings. But I doubt it, I think it's Xfce4's default browser, and at least builtin VPN seems extremely unlikely.

>>"Using what browser?" Firefox of course

in a bit of a rush now, I'll install another browser later or on the weekend to check what happens there.

You can open More Tools › Web Developer Tools from menu, switch to Network pane, check Disable Cache, next to it in options ("cogwheel") select Persist Logs — and open the full https://www.linkedin.com/ — you can watch the responses and where they come from. That should tell you who initiates the redirection, what host/IP sends that, using which codes etc.

If you suspect they are tweaking the responses based on your user agent, IP, locale etc. you can tinker with all of that, either by editing the headers and resubmitting right in the inspector, or you can try using VPN to give you a different regionality, change the content preferences to english, or use Responsive Design Mode to quickly change the UA string to a different device to see what happens if you look like something else from the outside.
