Hi,

Please try the Reset Firefox feature via Help (Alt + H) > Troubleshooting Information. If the problem persists you can also try to set No Proxy in Tools (Alt + T) > Options > Advanced > Network > Settings. You can also try to Disable Charles in Tools (Alt + T) > Add-ons > Extensions, or Plugins in the newly reset profile if it is installed by default.

(To revert to the previous profile you were using, close the new profile (i.e. exit Firefox), start Firefox and choose the Default User profile. While the Profile Manager is open, you can also delete the newly reset profile (the one containing random numbers), or the former profile, as the case may be). If the reset is okay, it would be a good idea to delete the old profile as otherwise it would be left intact with the previous data/cache until deleted.
