WebWorker support for extension background pages

[mayfield]

Hi, I'm trying to debug a performance issue with code that runs exclusively in WebWorkers created by my WebExtensions background page. Any plans to support this?

If you add "DOM Worker" to the thread filter on about:profiling, your thread should show up. It's probably in the WebExtensions process.

Thank you, I'll play around with that. Looks like "DOM Worker" is already captured but I'll try some more options in there.

Could it be that the thread is hidden at load time? You can try to use the "tracks" button at the top left of the window.
