Microsoft Edge API and IE Mode

Question

I like to open links from a sidebar inside a normal tab. This works in general but I am not able to open the tab content in IE mode of edge browser.

If I click a link in the sidebar:

• the tab content shall be loaded in IE mode (because we use an old intranet application),
• the tab content is always loaded in edge mode,
• it is not possible to change the mode of the tab (no action, if clicked the menu item or icon),
• it has no effect, if the address is in the edge property list for IE mode pages,
• if the same page load direct in a new tab (from address bar, not from sidebar) anything works as expected.

Do there exist any API property, call etc. / manifest property to activate the IE mode from the add-on js code? Do there exist any other solution to change the mode?

Answer 1

From the Supported APIs for Microsoft Edge extensions, there is no API to activate the IE mode from extension. If you want a link to be opened in IE mode, you could Configure IE mode Policies. Based on my research, there is no option to load a page in IE mode inside the sidebar. You need to select "open link in a new tab" and load it in IE mode.
