Redirect Guard wot Mew

This add-on would show a popup every time a site tries to load something from a different URL and let you choose what to load and what not to load freely. Though the popup can be annoying, the optimal way to use it is to find what you want to load, add them to the whitelist, and then switch the "Reject All" button on to block the rest.

(Even with "Reject All" turned on, it may still ask you sometimes when a page tries to redirect you after you click something yourself.)

We do no data collection, so you would have to build your whitelist yourself. Adding things to the whitelist is easy, though. When this add-on blocks or lets something pass, it will show up in the menu, and you just have to click "+Whitelist" to add it.

If you set it up right, it can block most ads as well, so we also have a "Help Sites" switch, which will load those ads in the background if you want to help any site you like.

WARNING: Some sites require you to allow certain URLs to load to show their content. For example, on x.com, you would have to allow twimg.com, or the content would not display properly.
