✅We currently only support Google Chrome and Mozilla Firefox.

❌Keep in mind that we don't support Safari. Using it might cause unexpected glitches or errors. Please switch to a supported browser.
​

Safari blocks media with sound by default. You can change that by updating a simple parameter:

1. In your Safari browser window, on the top, click on Safari > Preferences

2. On the top menu, navigate to the tab Websites, and on the right-hand side, select Auto-Play

3. Click on the drop-down menu next to 'When visiting other websites and select the option 'Allow All Auto-Play'.

You should now be able to play and hear all the media available in the simulations.
​
Alternatively, you can use any other of our supported browsers.
​ 

You may see a red screen in a simulation if you have limited free memory on your laptop. To fix this, here are the recommended options:

Try the Chrome browser instead. It handles memory better than other browsers.
✅Chrome: You can download it for free here.

✅Firefox: You can download it for free
​

Finally, if you still experience the issue, it may be because you have less than 4GB of memory on your laptop, which is one of the minimum system requirements for using Labster.

💻Please check the page above, to make sure you use a laptop that meets the minimum requirements.
