Systems and methods for hosting a browser within another browser

A system, comprising:

• at least one processor circuit;
• and
• at least one memory that stores program code configured to be executed by the at least one processor circuit, the program code comprising:
• a first browser configured to:
• receive a request at a first browser to navigate to a first page, the first browser having an open browser window;
• determine that the first page is incompatible with the first browser and compatible with a second browser;
• and
• responsive to a determination that the first page is incompatible with the first browser and compatible with the second browser, send an invocation request;
• to invoke an instance of the second browser in a separate process;
• and
• a second browser configured to:
• invoke an instance thereof responsive to receiving the invocation request, the instance of the second browser being configured to:
• load a host browser interface in the separate process of the instance of the second browser, the host browser interface being coupled to a browser frame layer of the instance of the second browser,
• the first browser being further configured to control execution of the instance of the second browser without a browser window opening for the instance of the second browser.

A computer-readable storage medium having program instructions recorded thereon that, when executed by at least one processor of a computing device, perform a method, the method comprising:

• executing a first browser in the computing device, the first browser having an open browser window;
• receiving a request at the first browser to navigate to a first page;
• determining, by the first browser, that the first page is incompatible with the first browser and compatible with a second browser;
• responsive to the determining, sending, by the first browser, an invocation request to invoke an instance of the second browser in a separate process;
• responsive to receiving the invocation request, loading, by the instance of the second browser, a host browser interface into the separate process of the instance of the second browser, the host browser interface being coupled to a browser frame layer of the instance of the second browser;
• and
• executing, under control by the first browser, the instance of the second browser without a browser window opening for the instance of the second browser.
