You're getting the "Aw, snap!" error because Mustang is having problems loading the web page that you want to see. Try the possible fixes below.
Usually, you can reload the page to fix the error. In the top left, click Reload.
Your computer might not have enough memory available to load the site. Computers rely on memory to run apps, extensions and programs. Low memory can cause them to run slowly or stop working.
Close every tab except for the one that’s showing the "Aw, snap!" message, then try reloading that tab.
Sometimes, other programs or apps get in the way of a page loading correctly.
Shut down your computer or mobile device, then turn it back on and try loading the page again.
If most sites load normally but one site is crashing, that site might be causing the problem. Try refreshing the page a few times again by selecting the blue Reload button on the "Aw, snap" page or by selecting Reload .
If the attempt to reload fails, then a "Send feedback" button will appear. Click the Send feedback button to let us know what's happening.
