what is perank fr?

PeRank is a browser extension that changes how search results appear on Google, Bing, DuckDuckGo, Startpage, Yandex, Brave Search, Ecosia, and Yahoo. It removes ads and sponsored results from the page, then reorders the remaining organic results based on relevance instead of the order the search engine chose. You can also view results in reverse order or keep the original sequence. The extension works in Chrome, Edge, Brave, Opera, and Firefox, and it detects which search engine you are using automatically. The reordering happens entirely on results already loaded in your browser. PeRank does not send requests to search engines or scrape pages behind the scenes, which avoids violating terms of service. A separate "deep search" feature tries to go beyond the first page of results, but it behaves differently depending on the engine. Ecosia can append additional results directly into a re-ranked section. Google, Bing, Yandex, and Yahoo offer to open your query in a different search engine where results may differ. DuckDuckGo, Brave, and Startpage have no deep search option because those engines do not provide a reliable way to load subsequent pages. PeRank gives you several ways to personalize results. You can blacklist domains to always hide them, or whitelist domains to boost their relevance score. Each result has thumbs up and thumbs down buttons that vote on an entire domain rather than a single link, shifting that site up or down in relevance mode by a significant margin. A star button saves results to a personal list called gems. All of this data stays in your browser's local storage, with no server involved. The extension supports English and Italian, with a language selector that can follow your browser setting or be set manually. Developers can add new search engines by creating one configuration entry that describes the page structure, and the core logic handles the rest. Search engine page layouts change over time, so these configuration entries may need occasional updates. The full README is longer than what was shown.
