Make sure to install Reddit Enhancement Suite so you can block submissions with unwanted keywords like Bieber from appearing on your Reddit page. I put inactive or small subreddits into my dashboard.
You should know you can only subscribe to 50 subreddits before Reddit randomly selects which are on your front page.
Some Recommended Subreddits
explainlikeimfive - ask questions and receive answers a five year old should understand, ideally. True Film - discuss great films with other cinephiles. True Reddit - Read and discuss in depth articles. Gaming Subreddits - these subreddits generally have better content than r/gaming, which has too much memes and Valve love for my taste.
Have you ever been on Wikipedia and spent hours reading random links? TV Tropes is like this but a thousand times more addictive. This site is much better than Cracked and it's not nearly as sophmoric.
Some 4chan posts are funny, but illegal pictures (which are removed very quickly) are posted on the boards, and you don't want those on your computer. If you want to delete anything safely, I recommend Eraser. Reddit has similar humor and stricter moderation.
You can download this script to block or ban certain domains. Google Video searches more websites than YouTube.
My favorite video site is YouTube. You should use these scripts which you can use directly with Chrome, or with GreaseMonkey for Firefox - YouTube Blocklist (block annoying YouTube users) and this Bypass YouTube Age Verification, if you don't want to create a Google account to use YouTube.
The Firefox add-on YouTube Comment Snob allows you to filter certain types of comments, or block them all.
I use Vimeo to watch free movies in usually higher quality.
My favorite browser is Firefox.
Mozilla has a page to check for add on updates.
Leechblock - create daily limits for yourself for websites like reddit. Swiffout lets you play flash games in full screen. AutoPager - automatically add the next page instead of always clicking next.

from third-party social media buttons while still allowing you to use them' (supports Chrome)
JDownloader lets you automatically download from multiple sites like Rapidshare, and if there are captchas a small box pops up (it doesn't interrupt as much as you might think) for you to download on those sites. You can set automatic passwords and automatically extract compressed files.
This site allow you to combine many freeware installers into one custom installation package; this site's very convenient for use on new computers.
If you want to torrent with legal sites like MiniNova, you should use PeerBlock and set the protocol encryption to forced in Utorrent's preferences (allowing incoming legacy connections means allowing peers that don't have file sharing encrypted, and makes downloading a lot faster). Some people pay to use proxy servers, but I don't.
I'm not advocating piracy, but if you want to know more about laws against file-sharing I recommend the site TorrentFreak.
I use this site, to manage what TV shows I'm watching. The site doesn't have any social features like sharing what shows you're watching or discussion boards, but it is a good tool. The site would be better with an auto-recommendation feature (I use IMDB for that) and bigger charts for popular shows.
My favorite websites and freeware.
