I use this Addon to follow updates one Software websites and the massive number of webcomics I read. The menu for the check options could be a bit more accessible. I would really like to have a version for Firefox on Android. I already sync my bookmarks, sadly I cannot check for updates on the items in the Update-Scanner folder.

I have been using this addon for a long time. I understand that ff changed its paradigm and so this addon had to as well. However, as other users have noted, it just kind of stopped working at all lately. I go to the site I have it check and there are major changes, but it always says no changes when run. I would love to give this five stars, but 3 for this current iteration, out of hope.

I get on and off problems with this potent app. Most recently, it has essentially stopped functioning and I get the message "We've detected that JavaScript is disabled in your browser. Would you like to proceed to legacy Twitter" when I try to open a scanned Twitter link. And it seems to work intermittently at best regardless of what I have fed into it. I think the problems arise when Firefox is updated.

Please make it a stand-alone downloadable app that can be used with any browser. Please let me contribute to the design of the format and help with the Beta testing and marketing. Thank you If interested please acknowledge on the developer's homepage and I will email my thoughts.

Fantastisch, spart unglaublich Zeit beim Checken von Websites auf Updates.

This extension does an excellent job of ensuring I know about changes to important web sites and full marks to sneakypete for updateing it to be compatible with the newest firefox changes.

I am japanese. Sorry broken English.

I have Fire Fox 56.


Older versions can not overwrite new versions.

Can I transfer data from old version to new version?

If you can, please tell me how to transfer the data.

5 stelle semplicemente perché è indispensabile

Since I discovered "Distill Web Monitor" I have abandoned this extension after years of use. Thank you.

Thank you very much for this new version.

Would it be possible on Mac OS (no middle click), when clicking on a website with detected changes, to open the page in a new tab?

I loved this add on. But then in one of the updates, I lost the ability to make my alerts appear for longer than a few seconds, to make them stay until I manually close them, which means I miss alerts all the time. Please, I'm begging you, give me back this feature!

Impossible de sélectionner une partie de la page qui doit être surveillée.
A consommé plus de 40 giga de data en 4 heures.
Quand le module est activé, une des instances de firefox a réussi à utilser 50 % de la mémoire (4gb/8gb).

This used to be a great FF addon. Now it has a memory leak that drags my computer to a halt. Can't use it anymore. And the delete button has been taken away.

UPDATE:
@SneakyPete Thanks for fixing the memory leak issue.
Any chance you can add a Delete button to the top banner, where the settings icon and "View Changes" drop down are?
Thank you.

there are no buttons anymore to add or manage the content being updated.

La exensión más útil que he usado, llevo años con ella

Works fine so far with Firefox Quantum (58.0.2) and AddOn version 4.2.0.
The problem:
you cannot delete a page from the UpdateScanner list, when you don't need a page to be longer in this list.
The page settings don't have any delete option :-(

Still using 3.3.2

A pity it isn't possible to modify the default interval setting (or couldn't find it)

* Previous version is better
* It would be more convenient if the ' Scan All Pgae ' button is outside.
* Please correct the error problem of Korean web page.
* Please modify search interval.
30/60 seconds / 120 seconds ...

So glad to have this on my phone

Let us set 15/30/60/120 second intervals

This Is Fantastic! This Is Awesome! I'm a Sweeper and I enter over 600 Dailys, but I also need to monitor 1000s of sites for changes to find more sweeps to enter. So far I have tested with approximately 100 sites, waited 24 hours and sure enough-Update Scanner detected a change on every page. The affect on the browser resources is unnoticable, even though this is Firefox.

I highly recommend this add-on to everyone.

What I would like to see in future releases:
-Sorting
-Adding New items directly to Folders
-Duplicate detection
-Set Global Settingsas well as Individual Settings

***UPDATE***
I am receiving error messages or no textual content at all from
Active Server Pages(asp) when using Update Scanner. Examples include:
http://710wfnr.listenernetwork.com/asp2/usepoints.aspx?status=current
http://fans.wava.com/asp3/contests.aspx
http://nashfmwisconsin.listenernetwork.com/asp2/usepoints.aspx?status=current

OK, I believe in my extreme use I should expect a hit on resources and performance
to Firefox. So I now am requesting additional features:
-Run when the browser is idle
-A Pause option, instead of having to Disable
