My Firefox Add-onsI'm using the following Firefox Add-ons (Extentions), which i find very useful for my online escapades.
# Scrapbook - Helps you to save webpages for later off-line reading, a great tool with editing tools etc.. Ideal for research.
# URL Fixer Fixes the common errors made in the URLs
# Dictionary Tooltip Gets the meanings right in the browser, along with pronunciation. A must-have for a quick word lookup.
# PDF Download Allows you to view in PDF or HTML, a nice, nifty tool.
# Daily Dilbert Daily dose of Dilbert.
# Download Statusbar A better way than the default Firefox Download Manager.
# Chroma Tabs A nice tints for the Tabs, with site-specific colors, easier to pick from the multiple tabs.
# Image Zoom Zooms the images right on the webpage, nice addition to the right-click menu.
