Hey u/username,

We will soon begin rolling out changes to Reddit’s User settings. It is getting a refresh that includes changes to ad personalization, privacy preferences, and location settings.

As part of these changes, we are retiring a setting that you have previously turned on that limited how we used your activity from the Reddit platform to personalize ads. We have replaced the setting with a new option to select categories of ads that you may not wish to see.

More details are available in our announcement and help center.

These changes are rolling out starting today and you may see the changes over the next few days.

On Android just use Brave browser and turn on the setting to allow tabs to play media in the background. Opera does the same thing.

Not sure what iOS options there are.

It’s by far the best mobile browser that let’s you run tampermonkey and uBlock on Android and it’s not close. I haven’t found an add-on that let’s me run video/audio in the background, so until then Brave stays installed so that running YouTube with no ads and the phone locked is an option.

Aside from that, Firefox gives fantastic customization options, runs well, and is less vulnerable to attacks specifically because it has a smaller market share and it makes more sense to target Chromium based browsers.
