Being safe while you surf the Web is extremely important, yet safe surfing sometimes seems like an oxymoron. For users of the Firefox browser, downloading security extensions can help increase your level of protection from worms, hackers, phishers, and the like.
I should note that even with these extensions installed, you won’t be perfectly safe. Visit sites only of trusted sources, and don’t download unknown files.
MY TOP 3:
BetterPrivacy BetterPrivacy protects against long-term tracking cookies that can’t be deleted. The extension makes you aware of those objects and deletes them for you. You can then sift through those cookies and selectively decide which you want to delete. It’s a simple but effective tool.
Web of Trust Web of Trust tells you about risky Web sites that deliver malware or send spam before you’re affected. When you surf to a site, Web of Trust displays a colored icon giving you its rating. Green means it’s safe. Yellow means you should proceed with caution. And red means you should avoid the site. Those icons are displayed next to search results or as an overlay on a site that is considered dangerous. It’s an important tool to have, if you want to be safe online.
