Can't capture screenshot on click, if a new tab opens immediatly - chrome extension

[Abhishek Sachdeva]

I am building a chrome extension that captures the screenshot (tab) on clicking, say, a hyperlink. The current tab is not being captured if a new tab opens on click.

Error: Unchecked runtime.lastError: Cannot access contents of url "". Extension manifest must request permission to access this host.

How can I capture the current tab in this scenario (not the new tab)?

For more details, please check this.

Thanks in advance!

You have to ensure that the tab you want to capture is the active one in its parent window by calling chrome.tabs.update(tabId, {active:true}) first

Thanks for replying. I had tried that but the UX is not smooth.

This was the workflow:

1. Click a hyperlink in the current tab (TabA)

2. Focus shifts on new tab (TabB)

3. Use chrome.tabs.update(TabA.id, {active:true}) to make TabA active again. TabA is in focus right now.

4. Once the screenshot is taken, shift focus to TabB using chrome.tabs.update(TabB.id, {active:true})

Steps 3 and 4 look like a flicker. Is there any way to do this without shifting focuses?

The  captureVisibleTab function can only capture the active tab. You have no choice but to deal with that limitation.

For example, cancel the click event so that a new tab is not open, then call captureVisibleTab and finally call .click() on the link element.

That is the only way for now it seems. Thanks for the help :)
