I rely on bookmarklets in my browser to handle some everyday tasks. These are the bookmarklets I use the most:

Scrapes out distracting elements of a page to improve readability of text.This works wonders on blog posts that you may be reading outside of your feed reader.

Mark something as “to read later” and add it to a list. You can download items from the list to your Kindle, etc., if you’re so inclined.

Selectively remove elements from a web page to make it easier to print out and use less paper.

For bookmarking sites.
