I am using the Experimental API in my private Firefox extension.

So far, I've been using Firefox 102 ESR, but I'm planning to switch to Firefox ESR 115. There's already a Firefox 115 Beta available, so I've started testing it with my private extension.

So far, I've been using internal Firefox functions like `loadOneTab` and `loadURI` and it worked very well.

I used the `loadOneTab` function like this:

``` const placesURL = "chrome://browser/content/places/places.xhtml"; window.gBrowser.loadOneTab( placesURL, { inBackground: false, allowThirdPartyFixup : true, relatedToCurrent : true, triggeringPrincipal : services.scriptSecurityManager.getSystemPrincipal() } ); ```

But the `loadOneTab` function no longer exists at all in Firefox's internal API. What should I replace it with?

I found the function `_createTab`:

``` // window.gBrowser._createTab({ uriString: placesURL }); ```

But the `_createTab` function returns an error:

``` Uncaught Error: UserInteraction with id "browser.tabs.opening" was not initialized ```

...I guess this is by security to make this function called only by user action? And I call this function inside `async function`.

Is it somehow possible to open a new tab from the Experimental API in Firefox 115 beta? I need this very badly. Really very much.

I used the `loadURI` function like this:

``` window.gBrowser.selectedBrowser.loadURI(linkGo, {triggeringPrincipal: Services.scriptSecurityManager.getSystemPrincipal()}); ```

The `loadURI` function appears to still be available in Firefox's internal API, but returns an error like this:

``` TypeError: 'uri' member of CancelContentJSOptions is not an object. RemoteWebNavigation.sys.mjs:28:41 ```

How to overcome this error?
