Круто, работает хорошо!

very usefull

I like it a lot the only one who let me check in seconds with sounds alarm as i need it in particular moments of the day, enabling/ disabling it .
( i would like actually to set it on fewer seconds checking like 5 seconds but there is still a limit ) .
Big + = is that when i enable it it remembers my previous settings automatically( rules and exception like "Where is not written that" etc ) .

On" special day discounts" i bet people can get the right moment it changes price of an item they look , i need it for a bit else, and it's the only free one that delivers so frequent "checks" with sound alarms , i can answer messages filtered by some words instead than receiving notification for all of them , sorting a particular page in a day and so on , really useful thank you .
Edit
.i get still "flase" alarms who dunno the reason , bt still pretty acceptable it really helps sparing time in sorting out .

Thanks for the great effort. Please tell me how to use the "Send Telegram message via bot link" notification option.

Easy to use, and it's free!
If you have a homeserver, this extension can be used to track the price of any page.
very complete with many notification options and customizable, perhaps it does not have a good interface but it is very functional 10/10

Very helpfull addon, thx to you. On thing that I would like to have, it's custome alarm sounds from hard driver. I can't find this function in addon. Also I find custom sounds function from web, but I got no idea how to use it (:

I've been using this for years to track prices of products and flights and I'm very happy with the results! One feature I'd like to see, which may not be possible, is if it can be set to use an existing opened tab to scan each time instead of opening a new one. The reason for this is on some pages (right now I'm on AA.com to track a flight) if I manually complete asearch for a flight my results show up. You can then refresh that page/tab you already have opened and it will "continue your session" and keep you active and refresh the search results. As soon as PageProbe runs a scan it opens a new tab with the same address as what I've manually searched for, but since it's a new tab AA.com sees it as a "new session" and gives me an error that my session has expired. I can continue to manually refresh the page where I did my manual search on, but PageProbe won't work since the website sees it as a new session and needs a new search. Any ideas or help on this would be greatly appreciated!

Great extension, stopped working at some point, but now works just fine.

I'm writing a review to give some love to this addon, most other addons are far too limited in the kinds of notifications they allow unless you pay! This one has a few notification options that I find very useful and one in particular that I desired, so 5 stars across the board! The only thing that would make it better is if it offered direct email notifications...

good for users who complained about "distill", but... for ordinary users, "distill" can graphically display what has changed on the page. plus, "distill" can select the monitored content through the extension icon (this extension opens the extension settings).
here you go into the extensions and everything is displayed with static text in the columns. there is no graphical representation of the changes. it is good for tracking simple and concise data, and if the Internet page appears to be a long canvas, then specific changes on it are unclear.

GREAT. AWESOME. Discovered it this morning. Spent just a few minutes to setup without prior knowledge of the tool. I can already enjoy a day long of monitoring ;-) . I'm monitoring some indicators about the quality of my internet connection, by querying some administration page of my modem. Really awesome. THANK YOU
EDIT: one week later, I'm even more impressed. The "integration" with IFTTT is also super handy. +++

It works great!

Is it possible with a cron every 10 seconds? or is every minute the lowest setting?

I now use Task scheduler to start Firefox and kill FireFox for the short every 10 seconds probes I do daily.

Edit: Thanks for the great addon!

UI could be improved to be more intuitive but it works lovely

I'm usually a picky bast*rd but this add-on delivers. I have tried many content tracking add-ons and I can confidently say PageProbe is by far THE BEST of its kind. It is highly configurable and very reliable. I use it for tracking product prices and thanks to it I've been able to save money on my online purchases. Just to mention some of my favorite features, it keeps a history of old values that it can display in graph form, it allows organizing trackers into folders and sub-folders, tracker import and export, and it's cross-platform (Firefox and Chrome). I experienced a bug which the developers resolved within hours of my report, and an update was released the very next day—really impressed. I'd love to see email notifications added in the future, if possible at all. Thank you!

This one worked much better than the previous one I tried.
