Is Coupons Search safe?
Coupons Search sets searchext.com as your default search engine, routing every address-bar query through a Yahoo-syndication redirect.
The extension's manifest overrides Chrome's default search provider so address-bar and default searches are sent to searchext.com, which forwards each query to Yahoo as a monetized syndication partner. The full search text is interpolated into the request URL on every default search. A content script on yahoo.com pages also overlays a full-screen 'Extension successfully installed / Click Keep Changes' prompt with looping audio that points the user at Chrome's button to accept the search override.

Findings
Default search routed through searchext.com to monetized Yahoo syndication
This extension sets searchext.com as the default search engine.
Searches from the address bar or popup route through www.searchext.com to a monetized Yahoo feed carrying its own affiliate tag.
A marker query reached Yahoo verbatim, tagged.
What actually happens
You type a search query into the address bar or the extension's toolbar search box and press Enter.
The extension's default-search override sends your query to www.searchext.com, which forwards it to a monetized Yahoo syndication feed.
The query is placed in the p= parameter of a GET request and carries the syndication tags hspart=ssl and hsimp=yhs-003 plus the extension's own affiliate type tag.
Captured request
Search results page served by Yahoo. A separate Yahoo geo beacon recorded c_str1=https%3A%2F%2Fwww.searchext.com%2F, confirming searchext.com as the referrer of the search.
The code that does this
The default-search override is set in the manifest; the handler builds the same searchext.com URL.
js/couponsearch.js — performSearch() builds the same searchext.com URL for free-text popup queries
js/couponsearch.jsvar performSearch = function (searchString, tabIndex = -1) { if (searchString) { isValidHttpUrl(searchString, function (httpCheck) { new Promise((resolve) => { if (httpCheck && httpCheck.isResolved !== false) { chrome.tabs.create({ "url": httpCheck.href }); } else { let typeParam = ("cs" + searchNumber + "-popsrc-" + (isFirefox ? "FF" : "CH")); let url = "https://www.searchext.com/search/?hspart=ssl&hsimp=yhs-003&type=" + typeParam + "&q=1&p=" + searchString; chrome.tabs.create({ "url": url }); } }, tabIndex); }); }};Hosts that receive the search query.
- www.searchext.com
Receives the typed query in the p= parameter as the configured default search engine, then redirects to Yahoo.
- search.yahoo.com
Yahoo (operated by Yahoo/Apollo Global). Serves the results page via its syndication program (hspart=ssl, hsimp=yhs-003) and records a referrer beacon naming searchext.com.
Observation
Search terms are query strings, not credentials or browsing history. Chrome displays a one-time consent prompt when an extension changes the default search engine; the override only takes effect if that prompt is accepted or kept, and it can be reverted under chrome://settings/search.
What it can do
Permissions this extension asks for, as declared in version 2025.6.55. Asking for a permission is not a finding on its own - it is what the extension can do if it chooses to.
