A fork of Autopagerize for Chrome, fully reworked to reduce memory consumption and increase performance:

• the background page now auto-unloads when inactive
• the content script is added to a web page only if its URL has a matching rule
• the content script unregisters all of its listeners when there are no more pages to load according to the paging rules - and thus it gets removed by the garbage collector (several megabytes per each tab)
• the URL matching regexps are cached upon each run of the background page so subsequent checks during the run are almost 100 times faster and take just a few milliseconds (the background page unloads after approximately five seconds of no navigation activity)
• IndexedDB is used to store the data objects directly whereas the previously used localStorage serialized them into a string
• Simple one-time messaging and in-place code execution is used when needed instead of the persistent communication ports that were created for all the browser tabs

Differences to the original:

• Exclusions are matched to the full URL now unless there's a * at the end. The original extension has been incorrectly treating all non-regexp URLs as prefixes.
  • http:https://foo.com/bar - this exact URL
  • http:https://foo.com/bar* - URLs that start with http:https://foo.com/bar
  • *.foo.com/bar - URLs that end in foo.com/bar
  • *:https://*.foo.com/bar* - URLs that contain foo.com/bar anywhere
