• (2023-08-15) Noel Henry: Doesn't work at all.
• (2022-07-07) Daniel Hobbs (Obbz): Thank you for freeing me. Would be handy if you there was a way of removing the thousands upon thousands chrome has added already... seriously google.. huge security issue here.
• (2022-06-11) Felipe Schenone: This extension has been so useful to me. Efficient management of my search engines boosts my productivity tenfold.
• (2022-05-19) Simon Cheng: Excellent! I personally use the search engine keyword feature a lot (e.g. g for Google, d for dictionary.com, wk for Wikipedia, wa for WolframAlpha, so for StackOverflow, etc.) and I hate sites randomly polluting my search list with entries I don't want. Would highly recommend. Edit: as of 2022 Chrome comes with a similar feature built-in - search engines are added but are "inactive" until explicitly activated by the user in Chrome settings. I think it's an arguably better implementation, which is why I will no longer be using this extension. Still, thank you Mr./Mrs. developer for your extension's great service!
• (2022-02-16) Ed Hasaba: Hasn't worked for a while :(
• (2021-11-13) Bradford Le: Works as advertised – honestly I'm surprised that most people don't seem bothered by having their search lists constantly bombarded, but to each their own I suppose. Anyway, yes this extension works. Thanks author!
• (2021-06-16) Vector79: Dead in the water. Doesn't work at all.
• (2021-04-13) Patrick Poyser: I have yet to see this do anything. removing extension.
• (2021-03-27) Dan Banfield: works great! thanks for building this.
• (2020-11-10) 최선호 (호야): 설치한 이후에 기본 검색 엔진을 다음으로 바꿔놨음에도 지멋대로 구글 검색엔진으로 검색되는 경우가 50% 쯤 됩니다
• (2020-09-18) Andrew Lewis: What a time saver, of course Google would require an extension to disable a bad feature...
• (2020-04-13) Jeremy Nyberg: Seems to work as advertised. I have visited and searched on CNN, Reddit, and Yahoo and no search engines have been added to Chrome. Thank you. Will update if anything changes.
• (2020-03-29) Qwandary: It doesn't work. My chrome browser keeps getting changed into a yahoo search regardless of having this add on :(
• (2020-03-09) Guillaume Dufresne: Chrome's default behavior is unacceptable, this is a life saver. Honestly. If I wanted to add search engines, I would add them manually. Thank you for making this extension.
• (2020-02-07) James Larrowe: Great! Now I don't have to deal with typing "s" and having a million search engines coming up.
• (2020-01-11) zxsteven 10: it works!
• (2019-12-05) Kelly Kane: Get's rid of the junk search engines!
• (2019-11-19) Emil Begtrup-Bright: WARNING! THE EXTENSION HAS MALWARE!! The extension has recently added malware that makes a browser redirect when you search google, and redirects you to an identical-looking page, that has another domain name... you can see this yourself, by doing the following: 1) add extension 2) use ctrl+k to search google in the omnibar, enter search term and hit "enter" 3) the google search loads. Go to a another tab. now go back to the tab with the google search. now the page has reloaded with another domain name than google.
• (2019-11-11) Hữu Lộc Đặng: Love it so much <3
• (2019-10-28) Peter Beckley: I've had this thing installed for years and just forgot about it. I just checked and not a single extra search engine clogging up the list of ones I've curated and custom configured!
• (2019-09-17) Louise Alker: This is the most amazing add on I have ever used.Thank you so much guys.It has blocked every search engine I usually get a big list under my default search engine and this has blocked every one.I don't usually do reviews on extensions but this has to have one.I am on windows 7 and in the UK if that helps anyone out. Big thanks again as I usually spend on and off the whole day keeping search engines from taking over.
• (2019-08-02) A DK: I've been using it for over a year, works perfectly.
• (2019-07-08) Michelle Hester: It works! That's all I can ask for.
• (2019-05-09) Stu Work: Thank you! I hate the way these search engines are added without my permission. now I don't have to.
• (2019-03-04) 雷雨: I hate this behavior, Thank you for your extension.
• (2019-02-05) PJ Haas: I liked it. Past-tense. Stopped working on updated versions of chrome. I miss it.
• (2019-01-01) It does nothing. I thought the developer comments and the recent update meant otherwise, but yeah, still nothing.
• (2018-10-15) Jim: Great idea, but it's not working for me in the latest version of Chrome. Search engines are still being added.
• (2018-10-14) Thiago Lages de Alencar: Thank you for making this extension, loved it
• (2018-09-15) Howard Samuel: This is the single most useful app I have in my Chrome browser... Gone are those massive lists of "search engine" options that are automatically installed every time you visit a new webpage... How they used to annoy me... Thank you so much for a clean & easy to use "install & forget" app that just works :)
• (2018-09-04) Yana Key: Search engines list is now clean! Thank You!
• (2018-08-21) Austin Smith: Works great so far.
• (2018-06-02) Matt Turner: The new version works with a 100% success rate for me. Thanks, brilliant work :)
• (2018-05-26) Shahed Faisal: The new version has been working good so far.
• (2018-05-23) reniaL Chen: Simple and working!
• (2018-05-08) Mike Harris: This doesn't work. Search engines are still added.
• (2018-03-25) vermeer grange: Many engines are still being added.
• (2018-03-07) Goog Man: While some custom searches are certainly being blocked, a list is still accumulating in Chrome's Settings. I posted a suggestion that the developer provide some kind of blacklist for sites we find are still being added to Settings. (Of course, I don't know if such an option is even possible.) If something like that happens or the developer finds another way to block the custom searches that are still getting through, I will joyfully amend my rating. Update: I now have over sixty useless and unwanted "search engines" in my Chrome settings, so, obviously, this extension does next to nothing. (I've lowered my rating from "okay" to "disliked".)
• (2018-01-08) Lee: Alas, this extension stopped working. Not sure as of which version of Google Chrome when it became ineffective. I was doing some maintenance, checked the search engines list, and there were many entries for sites that I had previously visited and used their search that were now listed in Google Chrome's search engine list -- all the while using this extension. I edited the search engine list to remove the unwanted entries (those that covertly add themselves to Google Chrome), revisited the sites, did a search there, and this extension did absolutely NOTHING to block those sites from adding their search URLs to the search engines list in Google Chrome. Example sites that add to the custom search engines list are: aol.com, yahoo.com, bing.com, ask.com, fleetfarm.com, gasbuddy.com, menards.com, 800notes.com, amazon.zom, bestbuy.com, ebay, and newegg.com. It is easy to spot the covert search engine additions when looking at the search engine list: they don't have a keyword assigned. Uninstalling and reinstalling this extension does not get it working. It might even show a number overlay on its toolbar icon as though it blocked the custom search addition but, nope, it didn't block anything. It has not been updated in over a year and a half. It's become useless and the author has abandoned this extension so it will not get updated to start working again (assuming however this extension worked before is still a viable method in the latest versions of Google Chrome).
• (2018-01-07) Chris Prall: Doesn't seem to work anymore
• (2017-12-31) Dizzy Finks: FAKE
• (2017-12-15) Flemming Sørvin: It blocks a number of sites but still a fair number of sites add their search engines.
• (2017-12-13) Sumukha R: Not at all helpful. Doesn't do anything.
• (2017-11-23) Prince B: not working

• (2020-08-24, v:0.0.6) Howard Samuel (Net Sense Design): Are you still supporting this extension?
  You have not made any updates in over a year and just does not seem as effective as it once was :(
• (2019-08-23, v:0.0.6) Lee Hodsdon: Add option to change your toolbar icon's color
  With Windows 10 and/or apps adopting a dark theme, your black toolbar icon disappears in a black toolbar. Add an option to let the user choose which color to use, like black, medium gray, or white.
• (2018-09-03, v:0.0.4) Lee Hodsdon: How about redefining the MIME type?
  The "Don't Add Custom Search" extension is still incomplete. I reviewed this extension in Jan 2018. Revisiting the sites still had them adding their search definitions to Chrome. The author came up with some new code. After a couple revisions, I re-reviewed this extension in Aug 2018. It is still flawed. Upon repeated revisits of sites that want to add their search definition, some still succeed - which means this extension fails. https://github.com/gregsadetsky/chrome-dont-add-custom-search-engines/commit/aa02ac9760de3bf58d03215067075151e6013368 That shows the code for the "Don't Add Custom Search" extensions. Looks like we have OpenSearch.org to blame for autodiscovery of search descriptors. From https://en.wikipedia.org/wiki/OpenSearch and https://www.chromium.org/tab-to-search, I wonder if an extension that redefines the application/opensearchdescription+xml MIME type would nullify the OpenSearch elements in a web page; however, maybe trying to change this MIME type's definition after the document (page) has already loaded (DOMContentLoaded) would be too late. From the Chromium article, this extension is using method 2 with an event listener.
• (2018-04-08, v:0.0.3) Dan Reeves: Breaks certain websites
  https://uk.webuy.com/ breaks while this extension is enabled
• (2017-12-19, v:0.0.1) Goog Man: Provide a Blacklist
  Your extension may block some custom search engines from being added, but it still allows many. Perhaps some sort of more aggressive blacklist can be added in the extension options for those more stubborn custom searches.

  Has anyone compared this extension to the UserScript? I read somewhere this doesn't work in all cases and I'm not sure if the extension and US are 1:1
• (2017-07-08, v:0.0.1) Roxanne McCloud: Give us the option to add the custom
  "X wants to add x.com search engine [Yes][No][No, Don't ask again]"
• (2016-12-12, v:0.0.1) Greg M: Had to delete 10 Search Engines
  Does not see to be doing much with newer versions of Chrome. Had to delete 10 search engines that snuck in to Chrome.
• (2016-09-27, v:0.0.1) Adam Moeller: Remove the counter
  I installed this extension because I like to keep my browsing experience clean. I don't like to have the extension icons change if possible. Can you add the option to turn off the counter?
• (2016-08-18, v:0.0.1) Madis: Unblocked search engines
  The following sites' search engines got still added: wordpress.com (and its rehosts) ebay.com emojipedia.org apkmirror.com okidoki.ee
• (2016-07-25, v:0.0.1) Thomas Østergaard: pricerunner.dk
  For some reason, the search engine of this site isn't blocked. It's the only one I've noticed that gets through still.
