This is one of my must have extensions. Especially useful for sites that don't have an RSS feed.

it doesn't work.

Great extension.
The only problem is opening the changes in the same tab and not in separate tabs

Have used Update Scanner happily for many many years and have had problems getting to grips with this update. What a shame as it was a wonderful useful add-on to FF.

Not happy initially with the changes. At first, having imported all my Update Scanner Bookmarks, I had a sidebar showing over 200 items all saying 'New Page'. By uninstalling and reinstalling that seems to have been rectified. However, seem to have lost all identification of changes on pages that I hadn't reviewed. Now have to start all over again.

Disappointed to lose the option to right click and ask Update Scanner to scan a page.

Comparing the Update Scanner for FF57, as of 21Nov17, with its predecessor: I much prefer the old version. The new version opens sites in a page of its own, with a name like "moz-extension://f79626ca- etc. etc.". If you click on a link in the page it no longer works; on seeing a list of changed files, you can't click on any of them. This is a major issue for me.

It was convenient, with the sidebar opened, to click there to scan all pages. There may be ways round these issues, but they're not obvious. A nuisance, not major. I usually scan manually, setting the automatic scan to once weekly.

As many have commented, the scanner often reports pages to have been changed when there is no visible change; I expect that is unavoidable due to the nature of the pages, but is a nuisance.

On balance I still find the current version better than nothing; in particular I have a list of sites to remind me which to check. But it's got worse.

-1 Star: had to search for my old update scanner bookmarks
-1 Star: and now i go manually through all ~200 pages again to define how often i want to upate them.
-1 Star: day, week, manually... dind't you forget the month? Event calenders sometimes change per month...
(really let us define when we want to check it! (re)Update this back to where we could choose any number of days.)

Firefox can be happy that opera is harder to customize for treestyle tab. There was a day i wanted to switch.

The new version does not play nicely with other extensions & open tabs and has become very inefficient. It's hogging all the Firefox 57 cpu cycles so Firefox and every page I have open is unresponsive while its running. Once it finishes (after 15 minutes now instead of 90 sec) everything is back to normal. While its updating, Firefox become completely unusable. I don't like the new menu - there's not enough control. And upgrading was a pain, with having to export & reimport which seems unnecessarily pointless.

It was my best add-on but the new version is more-more worse. Not working all webpages with other languages. There are no small menu icons upper the sidebare. I'm sorry but searching other add-ons.

It's soooo goooood. Thank you!

New version don't work on russian sites.
Now you addon is useless for me.

This new version is a mess in FF Quantum. It's inconvenient to use and not reliable. This feature is so important to me that I'll have to change browser soon unfortunately.

On ne peut plus lancer la mise à jour manuellement.
Si on surveille une page avec login (ex : forum), la page reste bloqué à la page d'identificattion.
Impossible de mettre à jour une page qui n'a pas déjà été scannée, je ne comprends plus du tout ce nouveau fonctionnement.
J'ai eu du mal à récupérer mes favoris mais c'est fait, ouf !
En tout cas, l'appli fait le minimum : surveiller les pages sans flux RSS, et cela me convient ^^

the last version was good , this new version of firefox sound that is have made the developer in hurry to keep it compatible .
well
i'm missing the functionality and the ability to LUNCH THE SCAN MANUALLY !!!

автор постоянно навязывает свое мнение что сканировать чаще чем раз в 5 минут плохо, для моих целей мне необходимо сканировать страницу не реже чем раз в минуту, в старых версиях можно было это выставить вручную, в новой версии такую возможность я найти не могу, вынужден установить старую версию,( этим приложением пользуюсь втечении 5лет ежедневно) если возможность более частого сканирования не будет востановленна я буду вынужден искать альтернативные варианты

the author constantly imposes his opinion that it is bad to scan more than once every 5 minutes, for my purposes I need to scan the page at least once a minute, in old versions it could be manually set, in a new version I can not find such an opportunity, I have to install old version, (I use this app for 5 years every day) if the possibility of more frequent scanning is not restored, I will be forced to search for alternatives

I have used the Update Scanner for 5+ years. It is indespensible for anyone who wants to stay on top of the latest announcements in Computer Technologies and programs. I check over 400 web sites every day!

this is one of my must have add-on,
it let me tracks with web page that have no RSS feed :)

please update this extension to 3.6

I agree...this is my favorite add-on and was bummed to discover that it is incompatible with the latest firefox, please update and soon!

Oh, I got it! One has to specify the color settings for each page separately. However, I would prefer to have a global preference too _and_ to have the option to specify the foreground color too.

Regards.

This is a really great add-on I won't miss.

Thanks a lot to the developer!

But the new color schema introduced with 3.0.8 will produce unreadable results in many cases. (white text on yellow background, yellow text on yellow background an so on)
See http://www.dpreview.com/ or http://www.macrumors.com/ for example.
Normally I would give 5 stars.

Update Scanner 3.1.0 for Firefox 3.6:

Great tool!

Saves a lot of time by checking webpages for any changes - very useful when websites don't include rss option totally or for that particular page!
Simply right-click to add the current page with the option to chose how frequent checks should be made and what details to check! Excellent!

3.02 fixed the installation error that I reported earlier.
