Update your browser to its latest version: Labster simulations work best on the latest versions of browsers. If you're using an older browser, consider updating to the newest version.

​Allowing Pop-Ups in Mozilla Firefox
If you're having trouble loading a simulation and notice a banner at the top of Mozilla Firefox saying that pop-ups are being blocked, follow these steps in this article.

If you are accessing Labster through Canvas, these browser requirements need to be checked

Restart your computer

If you are using an iPad, or Chromebook play via the app.

Check Your Internet Connection: Labster simulations require a stable internet connection. If you're experiencing issues, check your connection and try to reconnect if necessary.
​

**Note: Public WiFi networks at workplaces, restaurants, or cafés often have security features that can interfere with Labster simulations:

These interruptions can prevent the simulation from properly saving your progress or maintaining the active session state, potentially leading to corrupted sessions that require restarting.
​

For the best experience, use Labster on a private, stable network connection whenever possible. If you must use public WiFi, try to complete simulations in one sitting without interruption.
​

Start the simulation from the beginning (instead of loading a checkpoint)

In simulations where there is an equation or a panel, you won't see an error message. In these cases, you will need to visit the Theory tab to learn how to solve your question and continue with your simulation!
