Check4Change by Ronen Zilberman

Rated 4 out of 5 stars 140 reviews

27,355 users

Check4Change (aka C4C) is a simple extension that allows you to select a part of a web-page, and get notified when it changes.
Collector's Note If you want to check a page for changes occurring over a period of days/weeks/months, use "Update Scanner". If you want to be alerted about changes that occur over seconds/minutes/hours, use "Check4Change". Following RSS Feeds, if a page makes them available is the best way to keep abreast of changes made to a webpage, but if a webpage does not make RSS feeds available, then using "Update Scanner" or "Check4Change" is the only way to check whether any changes have been made to the webpage.

Resurrect Pages by Anthony Lieuallen

Rated 5 out of 5 stars 67 reviews

26,178 users

Dead pages, broken links, the scourge of the internet. Powerhouse sites like Slashdot and Digg can bring a server to its knees. What do we do when a page is dead but we still want to see it? Call in the clerics, and perform a resurrection...
Collector's Note There are two addons that let you open a cached version of a webpage(i.e. a snapshot of a webpage, that now doesn't exist or would not open, taken in the past) - ErrorZilla Plus and Resurrect pages. Both use 5-6 services like Google cache, Wayback machine etc. to show you cached pages. Both do so by adding links to the error page that shows up when you fail to connect to a webpage. The advantage of "Resurrect pages" is that it opens the cached page for each of the 5-6 services in a separate tab, thus allowing you to try all services quickly. The advantage of "ErrorZilla Plus" is that it also adds a Proxy button for you to open the webpage using a proxy service in case the website is inaccessible at your location/your country.
