Service workers

[danifs25]

Hi,

I've been using version 0.40.0.2 for quite some time now and I've decided to upgrade it last night the latest version 0.40.1.1.
I have monitoring hundred of articles on https://es.webuy.com/ and after the upgrade none of these pages would load.

So I tried the Browser Steps to see what's wrong but they loaded perfectly. I ran the chrome debugger and saw an error message like "Service workers disabled by Playwright". Looked at the code and yes, that was one of the changes from one version to the other. I've commented that line out of the code and boom, pages will start loading again.

[changedetectionio/content_fetcher.py](https://github.com/dgtlmoon/changedetection.io/blob/fcfd1b5e10536c24cf4fb81cee3fdbd81df157cb/changedetectionio/content_fetcher.py)
                # Can't think why we need the service workers for our use case?
                service_workers='block',

Can we make that available again or maybe as an env var?

Thanks.

@danifs25 wow thanks, yeah I think I committed this due to seeing a lot of bandwidth from youtube and other sites, but you're right, it should be enabled by default #1367

I can also confirm that the website you gave works when this is enabled
