I keep disabling the ads from my new-tab page, but firefox keeps re-enabling them. How do I permanently disable them?

Do you mean you go to the Preferences page and uncheck the box for a category but it later gets re-checked: Hide or display content in New Tab.

Have you noticed any pattern to when they return? For example, when quitting/restarting Firefox, when shutting down/restarting the system, after a certain time interval, at random?

Do you use Sync?

Yup, that's exactly it. I have not noticed any pattern that I can say for certain. It seems like maybe it's sometimes after a reboot, but it's definitely not consistently after a reboot.

Yes, I use Sync

Which section?

Let's say for example that you are turning off Snippets.

Have you used about:config? See: Configuration Editor for Firefox

In about:config, the corresponding preference is:


The preference for whether to sync that preference is called:


So you can individually disable Sync on that preference to rule out Sync as the source of changes. Double-click the preference to flip it from true to false.

Does that make sense?

At least I think that's how it works, I don't Sync any preferences.

The returning section is the 'recommended by pocket' ads. I've already disabled them in preferences and about:config. I hadn't seen those sync settings in about:config, so I disabled it there and will see if they return. Thank you

But I don't know why syncing would re-enable them as both of my computers have them disabled. I'm also confused as to why I would need to go to about:config anyway to disable something like that, when I've already disabled it in the UI.

Articles in the Recommended by Pocket section aren't ads, other than "Sponsored Stories", they are stories popular with Pocket users. Anyway, the preference for those is named


Does it get switched between true and false when you check and uncheck the box?

The corresponding Sync preference is named:

You can put lipstick on a pig and call it a woman all you want, but it's still a pig. I find it sad and disappointing that the Mozilla I grew to love and support years ago has these ads as a part of Firefox in the first place.

Yes,browser.newtabpage.activity-stream.feeds.section.topstories does change in about:config when I toggle that button in the options. I've disabled the sync preference for it in case that has something to do with it turning back on.

Hopefully that keeps these ads away Thanks
