What is a .adblock file?

.adblock files are plain text files used by browser extensions like AdBlock and AdBlock Plus to define rules for blocking specific website elements, advertisements, and tracking scripts. These lists are curated by communities and developers to improve browsing experience by making pages load faster and preventing unwanted content from appearing. You can often find updated filter lists online that can be easily imported into your ad-blocking software. They essentially tell your browser which content to hide or ignore based on patterns and URLs.
