Inject content scripts in already opened tabs at launch

As per Chrome store feedback:

Found a minor flaw with blocking specific elements on a page. Basically, if you have chrome to open a specific website when launched, it won't work properly until the webpage is refreshed. For example, let's say I blocked a sidebar in Facebook. Set chrome to open Facebook when launched and relaunch chrome. The sidebar won't be blocked until Facebook is refreshed.

My answer:

That would be gorhill/uBlock#108. Unfortunately, there is no guaranteed fix for this one, the browser doesn't wait for extensions to fully load before opening a tab, by design. There might be extensions out there which purpose is to manage tabs, and maybe one of them has a feature to prevent tabs from opening at launch unless you ask for it. I could try to inject content scripts into existing pages, but that would address only the cosmetic filters part (assuming this works anyways).
