See the sidebar for links to some issue trackers and browser extensions.

General advise

• Do not use more than one blocker extension! This includes Privacy Badger, Ghostery, and similar extensions, and also browser built-in blockers such as: Brave Shields, Vivaldi adblock, Opera adblock. Stacking blockers will prevent some filters from functioning, break websites, or cause performance issues. For more info see: https://x.com/gorhill/status/1033706103782170625
  • It should be generally safe to use a DNS blocker together with a blocker browser extension. Occasionally there may be some anti-adblocks that can detect if you do which otherwise would've been defused by the browser extension.
  • Firefox and Edge tracking protection should be safe to use, but they have been known to cause issues on some websites when used together with a blocker extension.
• Most blockers should be "install and forget" if you want to block ads and trackers. In some blockers you can subscribe to more filters that take care of various use cases, such as annoyances, social widgets, etc.
• Crafting your own filters or copying random filters from others will require you to maintain these filters. Old filters can cause issues. If something on a website is broken, see if there are any old filters that you may have manually added in the past.

Generic solutions

• Twitter issues
• uBO wiki

uBlock Origin will block a lot of non-dismissible anti-adblockers by default. To block dismissible anti-adblocks you can activate the uBlock filters - Annoyances filter in uBO Dashboard > Filter lists (Click on the arrow to expand the available lists). You can report any anti-adblocks that aren't blocked over at uAssets or the subreddit.

uBO enables the region/language-filter that corresponds to the locale of your web browser. So if there's a list for your region, then it will be enabled by default if your browser has your language locale installed. If your browser is in English but you're not in an English speaking country, then you can check if there's a filter for your region and enable it manually. Go to Filter lists and scroll down to Regions.

uBO can also be used as a script blocker.

I know this place is in it's infancy but it is beyond helpful to read FAQs and wikis you take the time to post. I'm not really technically savvy so I can't begin to describe what a valuable resource you provide.

I’ve had AdGuard installed as a VPN profile on one device and it’s working great blocking ads. I installed this week on a new device and it doesn’t seem to stop any of the in-game video ads.. anyone have any ideas?
