Features & Capabilities

Inspiration from Chameleon Dynamic Theme by Lin Onetwo and Huy Tran which is a fork of. It adds the extra colors from the Borderless White and Borderless Dark themes.

Unlike other themes this one changes tab background separator, toolbar field separator, toolbar top separator, toolbar vertical separator making things look more flat. It also simplifies the toolbar and sidebar.

Also compared with other forks it does not change the new tab theme for about:newtab and about:blank. This makes it change the color less often and you see less blips of color.

Is Borderless Chameleon Theme 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.

Borderless Chameleon Theme requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
