Use non-persistent background page about sponsorblock HOT 3 CLOSED

Thanks for the update and PR! 10 mb is a pretty good reduction in ram.

Right now the background script just waits for messages from the content script, so this should not be hard to implement. Good idea!

Since the PR was merged, I'll close this issue now.

@ajayyy FYI: The non-background script did reduce memory usage on my system somewhat, but extension still listens on all tab changes so still consumes resources when there are no YouTube videos open (on the main site or embedded). I still see the actual background process in the task manager often even when I do not have YouTube and do not have embedded videos. For me, the stack size fell from 3-4 MB to 2-3MB and overall process memory from 28MB to 19MB.
This happens because you still have an chrome.tabs.onActivated event listener that gets called each time any tab gets activated, so browser evicts the process from memory only if you do not do any tab changes and navigations within the same tab. The should be resolved when this event listener is removed.
