# Slow browser profile

When you’re dealing with a slow browser profile, there are two options to validate and fix the problem:

{% stepper %}
{% step %}

### Option 1: Validate proxy speed

When a proxy is used, internet speed is always determined by the browser profile. To validate, run a speed test in both the Incogniton browser profile and your own browser and compare results.

* Use **<https://www.speedtest.net/>** in the Incogniton browser profile and in your regular browser.
* If the Incogniton profile is slower, the issue is likely caused by the proxy. Contact the proxy supplier to resolve.
  {% endstep %}

{% step %}

### Option 2: Enable no sandbox mode

Turning on no sandbox mode in your account can also help.

* Go to **My account - Account settings - Browser Settings**
* Turn on **Enable no sandbox mode**
