Ask HN: Does uBlock hide the content of your Gmail?

I just checked and it doesn't seem to happen here, all emails show up OK when uBlock Origin is enabled. Does the extension offer other controls or filters you can experiment with?

Maybe you blocked some elements and an update broke that filter?

Check your custom filters.

I have several adblockers. It needs manual calibration. Especially creditcards need to be controlled before its send. I have no email from Google, but uBlock Origin.

As a confirmation, my friend had this happen to them today as well. Perhaps some sort of A/B test?

It was a bug, fixed now: https://github.com/uBlockOrigin/uAssets/issues/11906

In uBO settings, under filter lists... purge all caches, then 'update now'

As soon as I disable AdNauseam, it shows the emails. Do you have by chance both uBlock Origin and AdNauseam? That's a configuration recommended against.
