  • (2022-06-06) David Ibañez (Mutshadar): Aunque de primeras pueden agobiarte un poco todas las opciones que te presenta. Si te tomas la molestia de indagar un poco puedes descubrir todo el potencial que te ofrece esta sencilla extension. Para mi, se ha convertido en una imprescindible.
  • (2022-05-31) Pat MySecret: 2022 I would say it's as another review put it,..that it doesn't work on Dynamic webpages, and that seems to be all I wanted it for. 2016 Was hoping for something to let me know if a new ebay listing was added to a page. This didn't do it.
  • (2022-04-14) Arun M: Works but checks only once, check interval setting is not working

  • (2022-02-21) rk ml: Does not work on Dynamic web pages. Does not show any updates even though the pages have updated. For mostly static pages, this works well.

Last snapshot discarded. Changes highlighting will be available on next update. Error appears and the difference is not displayed. Looking at the settings, the registered URL list disappears. Every time I register, I save the setting list with Export, so I should import it again. Somehow it disappeared no matter how much I tried. If there are any settings to be made, please describe them on the help page.
  • (2021-03-03) Meshari Albarrak: I love it
  • (2021-02-20) sqorpy: Its look like no one maintain the code anymore. this extension is very flaky and unreliable. it use to be great few years ago.
  • (2021-01-22) Tzveta Dryanovska: Super useful and simple to use! Works great :)
  • (2021-01-22) Cengiarotti Zorzi: usando lo stesso account su altri pc non si sincronizza, si deve caricare le pagine da monitorare su tutti i pc manualmente.
  • (2020-11-28) Emanuele Francesco Russo: L'applicazione è ottima...ma nel tempo perde tutte le pagine che gli ho indicato da monitorare. E' la terza volta che tolgo e installo nuovamente l'estensione.
  • (2020-11-22) Peter Lee: When it works, it is great. Don't try using it with more than 2 or 3 pages. Once you get past 4 pages, it will just delete everything you were tracking and you'll need to start fresh from a blank slate.
  • (2020-11-10) Chris Pqe: Bonjour, Est-ce que la synchronisation par navigateur : - Chrome Extension Sync Pour synchroniser la liste à surveiller (pas le contenu de la page, mais uniquement synchroniser la liste de sélection) est prévue ? C'est le seul inconvénient, Merci
  • (2020-10-25) Николай Фадеев: Супер приложение. Единственное когда случайно нажал удалить проверяемую ссылку отката назад нет. Пиши "пропало". Или есть метод?
  • (2020-10-17) Alex Mendez: I love how straight forward the extension is but when clicking on the extension there is a bug where it doesnt show the websites that have changed. but the workaround is that you can have a chance to see which websites has changed. But there is another problem. when checking to see what the difference is, it "loads the difference" indefenitely. Workaround is that you have a chance to see what has changed...
  • (2020-10-14) ​ポール: Does not work. I set the refresh interval to 5 seconds and it didn't refresh for 10 minutes.
  • (2020-10-05) Logan Henry: Works good but it would be nice if it was possible to have different settings for the same page. That way you could have different sounds for different elements on the same page using the element picker.
  • (2020-10-05) Padma Sandro Casini: è già la seconda volta che perde le pagine monitorate. Inaffidabile

  • (2020-07-30) Elder Bernardes Teixeira: Gostaria de sugerir que o aplicativo funcione em todos as sessões do chrome logadas, usando os mesmos sites monitorados (sugestão: talvez criar uma pasta de favoritos no chrome e monitorar essas páginas, perderíamos as opções de filtrar elementos da página para monitorar, mas acredito que seria mais simples de implementar)
  • (2020-07-30) Jan Goyvaerts: The list of sites was cleared yet again. I'm using this extension for years now, but this is it. Sad.

  • (2020-04-15) Sharif I.: Requires a website to monitor changes!! Not directly in chrome.
  • (2020-03-16) Abdulrahman: It stuck in "Diffing in progress" most of the time. Any idea why this happens? The same happens in different PCs.

  • (2019-11-15) Ruriko Yurika Kashiwazaki Kusugawa: Fue una muy buena extensión , era una de mis favoritas, mostraba los cambios en la pagina cuando se actualizaba, ahora en la pagina que yo ponía ya no funciona, no se si sea asi para las demás paginas.

  • (2019-11-07) Luigi Cristiano: Segnala che le pagine sono modificate, ma poi non carica i confronti e i cambiamenti. In pratica non fa nulla.
  • (2019-09-27) Renato Paschoalinoto: Simples de usar e muito eficiente. Cumpre o que promete. Infelizmente tem alguns bugs e o fornecedor aparentemente abandonou a aplicação, pois a última versão foi liberada em agosto de 2017. Estou testando outra extensão: Distill Web Monitor

  • (2021-01-05, v:3.4.6) Jon Waskan: Repeat Alerts
    The checks and alerts seem to stop unless I click on "view changes." I'd rather refresh the page when I get an alert and scan for the changes myself. Is there a way to simply have the bell ring every time there's a change without having to click anything to reset it?

  • (2020-09-11, v:3.4.6) Damian Rubio: Lost Tracking Pages and Not Importing
    So, a couple of weeks ago I lost all the pages I was tracking. I did nothing strange, simply when I was going to click on "Check All Now" there was not a single page stored. Then, I realized that I could export the pages so if that happens again I can import them and not lose a lot of time looking for all the pages that I want to monitor and setting things up. Now, it has just happened again. I have lost all the sites I was tracking. But what is even worst is that I introduce the HTML file in the "Import Pages" dialog and none is loaded. How can the import be done? Is there any fix to the bug of losing all the monitored sites?

  • (2020-01-31, v:3.4.6) Nacho Ballesteros: How can I edit the monitored URL?
    The URL I'm trying to monitor (the root page of one domain) redirects to another secondary URL except on some situations (that's precisely when I want to be notified), but I can only add the redirected page in the extension (where the browser stops loading, not the typed one). If I could only edit this second URL to monitor the root page in the domain, that will be OK. Another solution could be typing the URL to add, not just once you visit the page.

  • (2020-01-21, v:3.4.6) Page monitor crashes Data lost
    Dear developer, I am writing you regarding the issue I am facing with Page monitor. I work with a HP chromebook. I use page monitor extensively to monitor news and updates from companies. I have had 3 instances where all my saved pages (at least 45) disappeared. I don't get an error or crash notification. It happens when I am surfing through notifications from page monitor. All the pages I have saved disappear and it's a pain to go through each website and save it again to monitor updates. Please fix this issue. Thank you

  • (2019-12-13, v:3.4.6) · Michael Medina: No Longer Works
    As noted in other support tickets, this extension no longer retains the settings, you can restore the extension files in your profile if you have backups but they disappear soon enough. Importing is iffy, sometimes it imports, sometimes it doesn’t. Even if it does they disappear.

    I'm getting 'dings' when changes happen, but when I click that notification, and a new tab opens, the "Diffing in progress" never completes, and never shows me what changed.

    Tonight I tried to visit the 10 pages that Page Monitor showed in the badge as updated, but when I clicked the toolbar icon, I got "no changes found." I tried "Check all now" but it was unclickable. I went into the settings and...every single page I monitor had disappeared. Luckily I had a recent export, so I tried importing that, but after pasting its contents into the Import UI, and clicking "Import," literally nothing happened, and there's still no content listed. Suggestions?
  • (2019-09-25, v:3.4.6) Artur Korneluk: Resolution for selector block
    I just found our you are a local developer in Vancouver, that's awesome! I love your monitor but I have one suggestion. Many websites I think are either catching on and don't want you to monitor their page or they have overlays on their page for some function or another that block your "selector". So when you try to use the "selector", you can pick the element however you cannot press "done" because something else is overlayed in the bottom right corner of the browser. If you make your window show up elsewhere or drag gable then this could be worked around. If you want an example, take a look at this page: https://www.buydig.com/shop/product/LG32GK650FBOB/LG-32-Class-QHD-Gaming-Monitor-with-FreeSync-Open-Box-with-1-yr-warranty?sdtid=13403074&omid=200&ref=cj&utm_source=CJ&utm_medium=Affiliate&utm_content=4485850&cjevent=2fe8574adfbd11e9824c00620a1c0e0d It's a monitor at buydig.com. Their rating system is overlayed on top of your selector and I can't press done. I've seen similar things like support chats take this space too which cover up the selector. It's always in the bottom right corner.
  • (2019-08-23, v:3.4.6) John Smith: Page Monitor Broken?
    Does this program not work anymore? Are there any updates planned to fix these issues? If I try to monitor a page then test it nothing will show up as if nothing was ever selected. I tried uninstalling it and reinstalling it then it would work for a small amount of time before it broke again. Will this be fixed anytime soon or are there any good alternatives?

  • (2019-08-08, v:3.4.6) CriMo Babelweb: Translated in French
    Hello, Your super software does not allow to delay the analysis of a page, or even to consult the changes of a page after the user is entered either his credentials or entered a value in a field, or even after filling a form that can contain a captcha. Could you integrate it or have you definitely stopped developing this tool? (last update of 2017!) 1. Delay: It sometimes happens, especially in the consultation of a page requiring to interrogate a database such as a parcel tracking, that the page requires 1 to 5 seconds to retrieve and display the information. In this case, Page Monitor requires it to time out otherwise it will never see the difference. It will fall systematically on the string "research in progress", still in my example of tracking of parcels. 2. User input: Sometimes it is necessary to fill in the credentials before having access to the page you wish to monitor. This can be a simple Id field, or identifiers or even a whole series such as a file number, a date of birth, the date of creation of the file and the entry of a captcha. The capture should be automatic and concerning the captcha, for each control, either Page Monitor uses an external tool (a site that "decrypts") or the user could enter it. Page Monitor should in this case display the image extracted from the site and offer the user input of what he sees so that Page Monitor can do the desired control. We will always have the advantage of leaving care to Page Monitor to monitor a page in the background without having to worry about frequencies and possible input form in addition to captcha. Thank you for giving me a return please. Thanks again for your great work :) Thanx to Google Translator for this translation not bad at all
  • (2019-08-08, v:3.4.6) CriMo Babelweb: Consulter les changements d'une page après avoir rempli un formulaire
    Bonjour, Votre super logiciel ne permet pas de temporiser l'analyse d'une page, ni même de consulter les changements d'une page après que l'utilisateur est saisi soit ses identifiants ou entré une valeur dans un champs, voir même après avoir remplit un formulaire pouvant contenir un captcha. Pourriez vous l'intégrer ou avez vous définitivement arrêté de développer cet outil ? (dernière mise à jour de 2017 !) 1. Temporisation : Il arrive parfois, notamment dans la consultation d'une page nécessitant d'interroger une base de données comme un suivi de colis par exemple, que la page nécessite 1 à 5 secondes pour récupérer et afficher l'information. Dans ce cas, Page Monitor nécessite qu'on lui indique de temporiser sinon il ne verra jamais la différence. Il tombera systématiquement sur la chaîne de caractère "recherche en cours", toujours dans mon exemple de suivi de colis. 2. Saisie utilisateur : Parfois, il est nécessaire de remplir les identifiants avant d'avoir accès à la page que l'on souhaite surveillée. Cela peut être un simple champs Id, ou des identifiants ou bien encore toute une séries comme Un numéro de dossier, une date de naissance, la date de création du dossier puis la saisie d'un captcha. La saisie devrait être automatique et concernant le captcha, pour chaque contrôle, soit Page Monitor utilise un outils externe (un site qui "décrypte") ou l'utilisateur pourrait le saisir. Page Moniteur devrait dans ce cas afficher l'image extrait du site et proposer la saisie à l'utilisateur de ce qu'il voit pour que Page Moniteur puisse faire le contrôle souhaité. On aura toujours l'avantage de laisser le soins à Page Moniteur de faire une surveillance d'une page, en tâche de fond sans qu'on ai a ce soucier des fréquences et éventuelles saisies du formulaire en plus du captcha. Merci de me donner un retour svp. Merci encore pour votre super travail :)
