I've got an extension: https://addons.mozilla.org/en-US/firefox/addon/bookmark-dial/ (and there are several others) that generate thumbnails. I know there is a service today that does it, but it won't be accessible from WebExtensions. It would be great if there would be a WebExtension API that I can call with a URL and that generates a thumbnail and returns a URL to it. Ideally there would be a way to modify the CSS for it (this is how I do it now: https://github.com/sblask/firefox-bookmark-dial/blob/master/lib/thumbnail.js#L89 / https://github.com/sblask/firefox-bookmark-dial/blob/master/data/thumbnail_tab_content_script.js) Alternatively, there could be streamlined version of what I do today: open a tab, hide it, apply style and capture it. What would be missing is hiding a tab (this is what I do today: https://github.com/sblask/firefox-bookmark-dial/blob/master/lib/thumbnail.js#L30 (collapsed + disabled)) and capturing any tab(not just the currently visible one) to allow for background generation.

Is this covered by chrome.tabs.captureVisibleTab() ? https://developer.mozilla.org/en-US/Add-ons/WebExtensions/API/Tabs/captureVisibleTab

No, because any tab should be capturable, not just the currently visible one.

This seems like a good idea, we haven't talked about it much because the whiteboard tag was wrong, but I can't imagine this being that controversial and I don't think there's anything that does this already. As a minor point I'm commenting on this bug using VerticalTabs which is showing a thumbnail of the window in the tab...

looking at this sample-code from developer.chrome.com there is an api in chrome to get the thumbnail. [1] "permissions": [ "topSites", "chrome://favicon/" ], -- [2] eightBallWindow.style.backgroundImage = 'url(chrome://favicon/' + data[rand].url + ')'; [1] https://developer.chrome.com/extensions/examples/api/topsites/magic8ball/manifest.json [2] https://developer.chrome.com/extensions/examples/api/topsites/magic8ball/newTab.js

(In reply to matthias koplenig from comment #8) A favicon is not the same as a thumbnail...

Any news on this?

I agree with this request. Why it is not available for the developer but it available for the Firefox itself? We need a thumb property for the topSite object.

I would imagine there may be security concerns in terms of how the resulting images would be used. A use case might be someone with a tab containing bank account or other sensistive information. Not saying FF is leaky about that, but just that it would probably be a concern on the user side.
