  • (2022-06-20) Yasser Aly: My Facebook business manager and my entire facebook account got hacked directly after installing this extension, and without resetting or changing my password and that's another proof that it was this extension since it has an access to the cookies, He used the cookies to access my account and removed all the members with full access to employee access then added his fake accounts and posted something that violates Facebobok policies to lead my account to suspension and now he spent over $15,000 from my accounts and credit cards and he still trying to take more, I own a digital marketing agency and I had many clients with large budgets for Ads and he just terminated all this and terminated my whole career and life after I lost all clients and many of them are sueing me now after the large amounts taken from their cards and the large thereshold of their Ad accounts I used to manage, I am speechless for real no words to describe how it feels, I never got hacked before for over 20 years with zero scams or phishing attacks and after all this, a chrome extension terminates my life, Please be careful and I hope no one ever to experience what I been through the last days.
  • (2022-03-03) BT O: The tool is actually wonderful. I've used it for years. BUT. And it's an enormous BUT. This extension overrides and locks your notification settings (along with other settings) so that you can't change them. Because of that, any website can now constantly send you notifications and spam you all of the time. How about the fact that any of those notifications of links that they send could be a virus. That enough evidence for you sir? I haven't even looked into the code or other permissions of this extension but just from that alone, it's a huge red flag and security risk.
  • (2022-02-28) Rafael Galeano: Que pasa con la extensión?? Desde hacer varios días al usar la opción "Validar html Local" recibo mensajes como "503 Service Unavailable, No server is available to handle this request." Alguna ayuda para solucionar esto? What about Web Developer Tool?? Since several days ago when using the "Validate Local html" option I receive messages like "503 Service Unavailable, No server is available to handle this request." Any help to fix this?
  • (2022-02-08) Mohammed Zuhair Alfaraj: Good But Why http?
  • (2021-12-02) Senthi Sri: Excellent!
  • (2021-09-29) Anthony Brettell: Has lots of very useful tools. It makes finding information much faster and less confusing.
  • (2021-08-23) Door and windows: thật tiếc khi biết phần mềm này muộn quá.
  • (2021-08-03) mneth7each: ottima vale il page info - media di firefox
  • (2021-05-04) Dev One: Always by my side. Very useful.
  • (2021-03-02) Алексей Кореляков: Автоматически подписывает на все уведомления от всех сайтов и блокирует отключение в настройках.
  • (2021-02-08) Ralf Longwitz: Occasionally very useful. But very annoying: Opens a new tab with itself each time I open Chrome. Why?
  • (2020-12-29) Alexander Schwamberger: беспощадно спамит рекламными пушами
  • (2020-11-26) Johan Sölve: I used to love this but recently it has started to allow all notifications on all sites, without any option to turn notifications off. It makes me turn it off. EDIT: Apparently this has been fixed since version 0.4.8 but it seems I had to "Reset Disable Features" under the Disable tab https://chrispederick.com/work/web-developer/help/#allow-notifications. Thanks Chris! Now 5 stars.
  • (2020-11-02) Cathy Xing: dont download its an virus
  • (2020-10-21) K Barcham: I love this extension. I've been using this for years to help with accessibility testing and highly recommend it to all of my colleagues.

  • (2020-07-31) Wagner Cateb: Very nice tool!!
  • (2020-07-25) WilderSoft Arredondo Torres: Siempre la instalo, cada vez que empiezo con una nueva pc incluso VM, despues de instalar Chrome instalo esta extensión.
  • (2020-07-23) Александр Князев: good
  • (2020-07-17) Pablo Molina Toledo: Excelente extensión, una de las mejores para el desarrollo web. Muy práctica "All-In-One"
  • (2020-07-09) Jean Frank Palacios Balbas: No funciono ninguna opción en Microsoft Edge versión Versión 83.0.478.58 (Compilación oficial) (64 bits). Hecho gracias al proyecto de código abierto Chromium y a otros softwares de código abierto (edge://credits/)
  • (2020-07-07) Mauricio Alejandro Araya Valencia: Excelente herramienta para los Full Stack y desarroladores, muchas gracias !!
  • (2020-07-06) Matt Gardner: In new versions of Chrome, new extensions do not appear in your toolbar. That means that extensions you install are not readily visible. You have to fish around to "pin" them. I think some kind of post-install explainer would help this obvious UX issue with Chrome.
  • (2020-06-28) Maria Serafimova: I'm using it for years. Thank you!
  • (2020-04-14) Towelie: Edit CSS doesn't work. No other extensions. No ublock. url on localhost.
  • (2020-04-11) Sparsha Dhar: Best extension ever!!
  • (2020-03-22) Eveline Frei: I really like this extension but I have 1 complaint that moves me to almost trash it every time it happens. Please, please, make the resize options keep the sizes entered. Every time, this extension changes/Chrome updates, I am up for re-entering all the window sizes I need and I generally only realise that they are lost once again when I most need them....yes, it doesn't take hours to re-enter them but it is really annoying.
  • (2020-03-18) xi si: The best!! Thank you!
  • (2020-03-10) Janosch Batschi: It forces notifications to be enabled on all websites in your browser without any option to turn notifications off
  • (2020-02-19) Pedo: fodaaaaaaaaaaaaaaaaaaa
  • (2020-02-13) Dominic Davies: I've only used it for the responsive layouts and it's helped me out a lot. is always up to date.
  • (2020-02-05) Stephane Faure: Pas seulement utile pour faire du développement, mais aussi pour faire des liens et des favoris vers des ancres !
  • (2020-01-30) Daniel Shively Jr: THIS IS THE MOST BEST BIG WEB DEVELOPER TOOLBAR THE OTHER ORAGED ICONED UDEV ONE SUCKS THIS IS THE REAL ONE ITS BETTER LIKES RATINGS VIEWS FEEDBACK SUPPORT STUFF LIKE THAT IS GOOD HERE THIS COULD BE BETTER YOU CAN MAKE IT GOODER ITS NICE BUT COULD BE NICER KEEP UP THE GOOD WORK AND OTHER THINGS AND ALSO GOOD LUCK AND STUFF!. I've been using the Web Developer extension for YEARS. As someone that works in the Digital Marketing industry, particularly focused on SEO, this tool time and time again has helped streamline many important tasks I have to do when evaluating websites. It's flexible, customizable, and just really makes life easier. Thank you to the dev, for years of use. I'm planning to make a small donation to the dev to express my gratitude, but I thought a review was due first. The best thing about this tool, which it seems other people have also expressed, is the fact that i can trust it. With so many extensions out there, and so much privacy intrusion and "hacking", I've become incredibly weary of what extensions or apps I install (extensions can give you viruses too), so when I see some extension or script that focuses on one thing, even if it has good reviews and a decent number of users, I'm hesitant to install anything and I start looking up the dev and his or her reputation, etc. This guy, man, I've been using this for so long, and the trust and reputation is there. This tool is a MUST HAVE for any web developers, search engine optimizers, or anyone that works closely with websites, really. 100% recommended, would give it 9999999999999 stars if I could!. WOW!.
  • (2020-01-19) Majk Majkowy: Nie da się dziadostwa usunąć! Ostrzegam, nie instalujcie tego wirusa!
  • (2020-01-17) Henrique Araujo: Top, melhor ferramenta para desenvolvedor
  • (2020-01-13) Daniel Beddows: It's completely unnecessary to auto-open a new tab every time this extension is updated. Regardless of what this extension does or does not do, it's a step over the line for me. There isn't even an option to disable it. I cannot think of a more intrusive way to notify me.
  • (2020-01-13) Vince F: Thank you for the 0.54 update! Fixed some my most used tools Color Picker, Guides, Ruler. Cheers
  • (2020-01-13) Jamin: Great up, but spams a changelog tab with every single update
  • (2020-01-09) hiep nguyen: Error!!! Cannot display "show element tag names" on Heading tags
  • (2019-12-17) Jon Penny: The extension just auto updated and wiped all my custom settings. I now have to add them all again. Not impressed with wiping user settings after updates! Edit: The resize now doesn't work at all. Added custom resize dimensions and they don't do anything.
  • (2019-12-17) Evgeny Dombrauskas: Lost all my custom resize dimensions after update.
  • (2019-12-15) Blimblam: Been using this plugin on Firefox 3+ in 2007, until now on Chrome. Just brilliant and simple.
  • (2019-11-07) Master: Начал получать push-уведомления с одного новостного сайта, которые не мог отключить через стандартный отказ от уведомлений. В настройках Хрома вижу следующее: "Уведомления: Разрешено расширением". Начал последовательно отключать расширения браузера и выяснил, что неотключаемую опцию уведомлений в браузере активирует это приложение. Спрашивается: вот что это за дела такие?
