Hi,

If the TOR Browser Bundle is installed you would have two versions of Firefox: the original Mozilla Firefox and the customized TOR Firefox. You can try to start the Firefox that was installed by TOR. If you have security software (antivirus, firewall etc.) installed, you can try deleting all existing instances of TOR and TOR Firefox and its related processes/files in all the different configuration areas/modules of the security software like process monitoring, sub/spawned process control, virtualization etc. in addition to the main AV/Firewall module. Instead create new fully allowed/trusted rules for TOR and TOR Firefox + its related processes. Even otherwise some security software may also ask again when TOR/TOR Firefox is started and you can try to allow/trust at that time. Please see this.

You can also try updating the original Mozilla Firefox, set No Proxy in Tools (Alt + T) > Options > Advanced > Network > Settings and check.
