Unregister all service workers in Firefox.

firefox-unregister-all-service-workers.js

# navigate to about:debugging#workers first
for (let k of document.getElementsByClassName("unregister-link")) k.click()
for (let k of document.getElementsByClassName("qa-unregister-button")) k.click()

they changed the className, at least in Firefox 81, now should be:

for (let k of document.getElementsByClassName("qa-unregister-button")) k.click()

they changed the className, at least in Firefox 81, now should be:

for (let k of document.getElementsByClassName("qa-unregister-button")) k.click()

I've updated the code snippet. Thank you!

I had to update it to the following to work for me on FF 87.0

for (let k of document.querySelectorAll('[data-l10n-id="unregister-button"]')) k.click()

Thanks! This did it for me (FF 101.0b9, Developer Edition):

$$('.qa-unregister-button').forEach(b => b.click())
