About this extension
VEIL is an ad blocker and tracker blocker for people who want the advert gone and the page left alone.
WHAT IT DOES
• Stops banner ads, video adverts, pop-ups and popunders, tracking beacons, social widgets, cryptominers and known phishing and malware hosts.
• Ships 39 curated filter lists — uBlock Origin, EasyList, EasyPrivacy, AdGuard, Peter Lowe's, AdAway, URLhaus and twenty regional packs — compiled into 312,708 host entries and 21,737 request rules at build time, so protection is complete on the very first page load.
• Takes the empty ad slot out of the layout as well, so pages reflow instead of leaving holes where the adverts were.
• YouTube has its own control page: prerolls, mid-rolls, overlay and feed adverts handled separately. Twitch too — ad breaks are cut out of the stream, and if a cut would ever cost you the broadcast, VEIL stands down and lets it play.
• Anti-adblock walls are dismissed so the article stays readable.
• A badware interstitial names the list that stopped a host before you can go any further.
PRIVACY
No server, no account, no analytics. Settings and history live in your browser's own storage on your machine. The site icons in the activity ledger are the ones your browser already fetched for tabs you have open — VEIL never asks a third party which sites you visit. Optional settings sync rides your browser's built-in sync and stays off until you turn it on.
TRANSPARENCY
Every block is logged with the request, the site, the category, the list and the exact filter that matched. Open any row to see why it stopped.
You can trust a site, quiet a category, write your own filters, or import a uBlock Origin backup in one click.
