There is however a way of reverting this (for now?):

1. Load about:config in the Firefox address bar.

2. Click Accept the Risk and Continue, if the prompt appears.

3. Search for extensions.quarantinedDomains.enabled.

4. Set it to FALSE.

5. restart Firefox.

It’s just big tech trying to get it greedy fingers on money anyway they can! I understand it costs money to run websites, but it’s getting to the point where a lot of sites and ad revenue setups are starting to have more ads then actual content, like back in the 80’s and 90’s. And do t forget about the scripts that track everything up do so they can pinpoint ads that will peel to you, at so they think, based on browsing and search history. Hell even brave is starting to put ads and trackers in its browser

Everything. They don’t care about nothing but making more money. Greed will be the death of everyone who isn’t already rich.

I originally started with Knoppix in 1998 used that unitl i9 switched to ubuntu warty warthog and following versions until unity came out in then I switched to mint as unity constantly crashed my machine. stayed with mint for like 5 years, then moved to fedora for a year, switched to tumbleweed because I got tired of the SELinux in fedora causing issues.

Been on endeavourOS for a year now, and if i do decide to migrate a gain I will be going full vanilla arch.
