Firefox 60.0.2 works great while connecting to internet without using Cisco Anyconnect in my Mac (OS 10.12.6). I'm having this issue even with previous versions. While connected to my corporate VPN using Cisco Anyconnect, the internet connection not working most of the times. It works sometimes. I have tried with different configurations in 'connection settings' like 'Use system proxy settings', 'auto-detect proxy settings for this network' etc.,. While opening firefox, it asks for the proxy server credentials, later when i access any website, it gives 'The proxy server is refusing connections' error. However, Chrome browser connects to internet with no issues (with&without Cisco Anyconnect).

Hi, The Cisco AnyConnect VPN Client has been retired and is no longer supported.

It maybe having issues as per above as well you are running the Extension https://addons.mozilla.org/en-US/firefox/addon/cisco-webex-extension/

Try running in : SAFE MODE

In Firefox Safe mode these changes are effective:

  • all extensions are disabled (about:addons)
  • default theme is used (no persona)
  • userChrome.css and userContent.css are ignored (chrome folder)
  • default toolbar layout is used (file: localstore-safe.rdf)
  • Javascript JIT compilers are disabled (prefs: javascript.options.*jit)
  • hardware acceleration is disabled (Options > Advanced > General)
  • plugins are not affected
  • preferences are not affected

TEST''''is issue still there ?

Hi, I have the same issue in 'safe mode'. I'm using 'Cisco Anyconnect Secure Mobility Client', Version: 4.2.x and it is still under support. https://www.cisco.com/c/en/us/support/security/anyconnect-secure-mobility-client-v4-x/model.html

Then please tell me why Cisco has published the page I referred to : Cisco AnyConnect VPN Client - Retirement Notification The Cisco AnyConnect VPN Client has been retired and is no longer supported. You can view a listing of available VPN and Endpoint Security Clients offerings that best meet your specific needs https://www.cisco.com/c/en/us/obsolete/security/cisco-anyconnect-vpn-client.html

Can you do that ?

Pkshadow, With my brief reading, i found out the below:

Cisco Anyconnect VPN client: It only provides endpoint VPN access. It is no longer supported by Cisco.

Cisco Anyconnect Secure Mobility Client: In addition to VPN module, it also consists of several other modules like Network Access Manager, Posture assessment, Telemetry, Web security, Diagnostic and Reporting Tool, Start Before Login etc.,. It is under support by Cisco. Source: https://www.pluralsight.com/blog/it-ops/cisco-anyconnect-secure-mobility-client
