The permissions being requested are what is offered by the supported browsers. Adblock Plus only uses the permissions necessary for ad blocking.
To understand this permission, it’s important to know that ad blockers work by first blocking a web page's requests to download ads from the servers that host them. Secondly, by hiding any ads that can't be blocked.
To do that, the extension needs to:
- See every page you open so that Adblock Plus can work on every page you visit. This also means that Adblock Plus knows the URL of every page you visit.
- See all the data on the page to find any unblocked ads among the other content. This also means that Adblock Plus can see any forms you submit and your browsing activity on that tab.
Granting "Webpage Contents" permission allows Adblock Plus to hide ads if they can't be blocked.
Clearly spelled out: Adblock Plus does not record your browsing history, capture any data you enter in any web forms (including passwords), or change any data you submit on a web form.
