Can't browse in Firefox after closing AirVPN client

[dschubba 0]

Scenario :

 

1) Launch AirVPN (network lock mode)

2) Launch Firefox

3) Browse any website and leave Firefox opened

4) Close AirVPN the "clean" way (AirVPN menu > Exit) : DNS settings are back to normal (I verified this)

 

5) Try to browse some other websites from the previously opened Firefox window : webpages won't load (blank page)

6) Close Firefox completely

7) Re-launch Firefox : this time webpages are loading normally

 

Why do I have to restart Firefox once I'm done with AirVPN client ?

 

BTW, if I launch another browser (IE, Vivaldi or whatever) at step 5 webpages are loading normally

Hello!

 

It looks like a matter related to sockets. . Also consider DNS caching by Firefox. The browser (but this behavior might change on different Operating Systems) might still be using some "old" socket, when your system had a different default gateway, a different routing table, different DNS settings and even an additional network interface

 

When you restart the browser you get rid of all of the above.

 

The behavior you describe has been successfully reproduced on various GNU/Linux systems (for example Debian 7 and 8) and is considered perfectly normal.

 

Kind regards

Thank you for the explainations. It's not a bug, it's a feature. 

I've used a Firefox extension called "DNS Flusher" but it didn't work.
