This extension blocks unwanted popups. Clicking on the extension icon activates/deactivates the extension. Once active all new tabs will be prevented from opening EXCEPT internal pages (URLs starting with "chrome:" or "about:") or if the user presses CTRL while clicking on a link; every other tab will be prevented from opening. This extension was inspired by the TabBlock extension by xconvic.
Popupblocker
This add-on can block every popup. Many websites open new windows with ads, when you try to mark text or click something.
Popup Blocker
This extension automatically closes tabs and windows opened by ad-requiring sites You may be browsing normally and then you click somewhere on the page and then a new tab opens, suddenly, pointing to an ad, without you initiating it. This extension automatically closes those tabs/windows. It's not an Adblocker; it's a tab/window-containing-ad closer. ;) Once a site has that behaviour (where it opens random popups/tabs annoyingly), simply click on the extension and click "Add Site". Once that is done, the extension manages all tabs and windows opened from that particular site, automatically closing them if needed. To remove a site from the "monitored list", you can always click the extension again and click "Remove Site". Note that I intentionally created the extension to be lightweight, doing nothing but its intended task. Note that after adding a site, all new tabs opened that start with the protocol+hostname of that site will be allowed; all others won't. This means that if https://www.adopeningsite.com is added, then all sites starting with https://www.adopeningsite.com like https://www.adopeningsite.com/clickads or https://www.adopeningsite.com/hoverads will be allowed to open in a new tab. The others will be automatically closed. To purposely open a new tab that has its protocol+hostname different from that of the site, right click the link and choose "Purposely open in a new tab".
Advanced Popup Blocker
Block pop-up windows and tabs aggressively Stop aggressive pop-ups, pop-unders, and redirect scams for good. This extension uses a powerful, multi-layer defense system to keep your browsing clean, fast, and safe: Layer 1: Network Blocking Instantly blocks known pop-up, ad, and scam domains at the network level using declarativeNetRequest. This is the fastest defense, stopping threats before they even load. Layer 2: Script Interception Neutralizes tricky overlays (like fake video "Play" buttons or "You've won" messages) that try to force open a new tab. It cleverly intercepts these window.open calls without breaking the website. Layer 3: Redirect Chasing For the sneakiest pop-ups that slip through (like about:blank redirects), our event-driven background script monitors the new tab and closes it instantly if it redirects to a suspicious URL. It's lightweight, privacy-first (it never reads your history), and gives you a simple On/Off switch. No complicated setup, just effective blocking. Version 2.2: The 3-Layer Defense Update! This is a massive update focused on performance and reliability. NEW - 'Layer 2' Script Interception: Added a new content script that intelligently neutralizes deceptive on-page elements (like fake video players) that try to trick you into opening a pop-up. OPTIMIZED - 'Layer 3' Redirect Chaser: Rebuilt the background script from the ground up! We've moved from a setTimeout (polling) method to a 100% event-driven model (tabs.onUpdated). RESULT: The extension is now significantly faster, more reliable, and uses virtually zero CPU. It catches redirects instantly, eliminating the "race condition" of the old version. UI: Simplified the interface to a single On/Off toggle for maximum ease of use.
