Review summary

Users generally praise Block or Highlight Search Engine Results for effectively removing unwanted sites from search results by domain, and for offering both hiding and highlighting options. It works with major engines (Google and DuckDuckGo) and can handle large blocking lists, which many find life-changing for research. However, the experience is not flawless: blocking is not universal across engines; some searches (notably Startpage) don’t get blocked reliably. There are limits on how many pages can be blocked and potential performance issues as the block list grows, plus occasional partial hiding. Android support and ongoing maintenance have been noted as concerns.
Pros
  • Effectively blocks/hides results by domain across Google and DuckDuckGo, cleaning up search results.
  • Offers both blocking and highlighting options for domains, giving flexible filtering.
  • Capable of handling large blocking lists (thousands of sites).
  • Significantly improves research workflow and reduces clutter, often described as life-changing.
Cons
  • Engine compatibility issues: Startpage (and some newer engines) are not reliably blocked.
  • Blocking is incomplete: some results (top or sponsored) may still appear.
  • Block list size limits and performance issues as the list grows (sync can choke).

2026-03-06 Ba***** Too many entries cause Mozilla Sync to choke, but if Mozilla Sync isn't part of the equation or you're willing to work around that limitation, it'll happily sort thousands of sites!

2025-04-25 Fi***** Been using it with DDG, and it's been life-changing. No more raking through SEO optimizers with useless articles that go on forever. Blocked, moved on. Now my research is free of the mental load of weeding out these websites. Recommend 11/10

2025-03-31 Na***** The limit of blocked pages is incredibly low. I hit the limit within 2 hrs of researching.

2025-02-14 Fi***** Works great for Google. But. The docs say it'll work for other search engines, but I can't figure out how to make it happen.

2024-12-18 Ta***** Great for studying purposes to filter out less credible sources and highlight those with constantly good information. Not to mention the filter for clickbait websites that buy the top spots for google results. Well done.

2024-11-27 Bl***** Works great on PC. Not available for Firefox on android.

2024-10-29 Fi***** I was wary looking through the needed permissions for this extension so an independent review of how that data is used would be welcome but it does exactly what it says on the tin. I put in fandom.com and block in the settings and it blocked all fandom.com search results from showing up in DuckDuckGo just like it says it will.
