User Reviews

When choosing a colour in the extension on the tool bar, it closes the extension window. Would get 4 starts if this didn't happen. don't use if you're using multiple enviros all at once.

Is URL Theme Switcher Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
