Why don't Facebook pop-up windows don't work in Firefox 57 (Quantum)

After the upgrade I found Firefox 57 (Quantum) doesn't always work with some Facebook features, such as when posting converting a URL to a Website preview. Looking into this I would an article "Firefox Quantum SharedWorker not work" on Stack Overflow suggesting SharedWorkers don't work on Firefox 57 when multiprocessing is enabled. I then followed the suggest of disable functionality via the warning on about:debugging#workers page.

Was it just coincidence that this fixed the problem, or is there really some feature missing on Firefox 57 (Quantum) when multiprocessing is enabled?

Sorry, forgot to allow there was already an exception for popup windows for facebook.com, and the Stack Overflow article is here .

Yes that is the fix, as to something missing, no idea. Firefox Support Volunteers are not told such things. Is probably being worked on, 58 brings Multi-Thread next.

If this answers your question could you please mark it as solved by you so that others will be able to find the information.

Thank You.

You can disable multi-process windows in Firefox by setting these prefs to false on the about:config page.

  • browser.tabs.remote.autostart = false
  • browser.tabs.remote.autostart.2 = false

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.
