MetaSpy Protection 1.3 — What's New

Stronger Ad Blocking
Expanded the ad-blocking filter list from 9 to 56 rules, now covering all the major ad networks and exchanges (AdNexus, Criteo, PubMatic, Rubicon, OpenX, Media.net, mobile ad SDKs like AppLovin/ironSource/Vungle, and more).

New: Popup Blocker
Blocks popup and pop-under windows outright, before page scripts can even open them. Blocked-count shows as a badge on the toolbar icon per tab. Whitelisted domains are exempt, same as the ad/tracker whitelist.

New: YouTube Ad Blocking
A dedicated, opt-in toggle that hides YouTube's display/masthead/feed ads and auto-skips or fast-forwards through in-player video ads, plus blocks YouTube's ad-tracking network calls. (Note: this is best-effort — YouTube increasingly stitches some ads directly into the video stream itself, which can't be filtered without breaking playback.)

Light/Dark Theme Support
The popup now follows your system's light/dark mode automatically, instead of always rendering in the dark teal color scheme. Also fixed scan-result text (Safe/Danger/Loading) that was previously unreadable in some states.

Under the hood
- New "Block Popups" and "Block YouTube Ads" toggles added to the options panel
- Whitelist now covers ads, trackers, popups, and YouTube ads consistently
