Hello,

i have coded an WebExtension-AddOn for my personal use. In short: I add a new network protocol to windows 10 (player://) and connect this with an special windows script. Now i have coded an AddOn that create an context-menu that reparsed the link and use it for an tabs.update() action. As an example on youtube player://http://www.youtube.com/videolinkasexample.

```
browser.tabs.update({url: "player://https://www.youtube.com/asanexample"});

```

This called the ne protocol and shows up the protocol handler in firefox and the actual tabs was not updated, the tabs shows allways the youtube-site where i have called the protocol link.

This has functioned a long time with firefox version with WebExtensions. In the newest Version it happend nothing.

So then i have used tabs.create() and all functioned, but with an ugly new empty tab.

And i have figured out one strange thing:

When i call:

```
function updateFirstTab(tabs)
	{
		var updating = browser.tabs.update(tabs.id,
		{
			// active: true,
			// loadReplace: true,
			url: 'player://http://videoadress'
		});
		updating.then(onUpdated, onError);
	}
var querying = browser.tabs.query({currentWindow:true});
		querying.then(updateFirstTab, onError);

```

and the directly after this call an tabs.create()

```
browser.tabs.create({
		url:"https://example.org"
	});

```

He opened the tabs.update() and the tabs.create()

Is that an security change? Or an bug? But why tabs.create triggers an protocol tabs.update?

How can i call an protocol link in an context-menu without changing the actual tab. Ghostly;)?

Or when i must use tabs.create, how can i close the created tab after call the protocol - linkurl?

thx

Closed in the newest update 78.0.2 all functioned perfectly with code again. That was a bug from an previous version.

@jscher2000  
Hi, that problem i don’t know. By chance i have after i stopped the debugging of my addon by habit klicked a video link and received the protocol-popup. And then i have seen an firefox update from 9th july, yesterday. In the changelogs i don’t have seen a special entry about tabs.update() and i think that must another bug that have triggered the tabs.update() bug.
