Selection of extensions operating in particular - and not always exclusively - on the browser chrome.

Docs online viewer

Transforms the browser into a document viewer. Allows you to load almost any format by taking advantage of the Google API Doc.

Personal Blocklist

Prevents some sites included in the results of the search engine Google, at the discretion of the user. Sites with popup advertising pages in overcrowded farms, content pages in the background and may disappear from the landscape.
We can then edit the list of blocked sites.
This is now also a feature of the search engine (for registered users) so the extension is no longer useful.
