My extensions, in no particular order (I tried to order them based on usefulness, but I’d be here all night; well, I may be here all night, but at least I won’t be occupied with that single task…Enough! On to the browser extensions–>):
[ul]
[li] MouseGestures: Like everyone else who’s recommended this extension, I curse and make faces when I have to use a browser sans mouse gestures. I probably don’t use this extension to it’s full capabilities, but even just for moving forward and backward in a page or closing a tab, it’s so worthwhile.[/li][li] Tabbrowser Extensions: Again, mentioned already in this thread. Really, if I had to only have one extension, this might be it.[/li][li] StumbleUpon: A bit complex to explain, but a lot of fun and an interesting idea. My SU page is here.[/li][li] QuickNote: Allows you to take notes right in your browser, as well as highlight text in the browser and immediately send it to a note. I just realized how frequently I would open up Notepad for such things, and this is saving me a step.[/li][li] MozillaCalendar: Adds a calendar with dates, appointments, etc. into my browser.[/li][li] BugMeNot: This one’s already been talked about. Makes a useful thing SUPERuseful.[/li][li] CopyImage: extends the usefulness of right-clicking on images with “View Image,” “Copy Image,” and “Copy Image Location”[/li][li] GoUp: I got used to this feature using the Google toolbar. Allows you to type “Alt+UpArrow” and go up one directory level in your current site.[/li][li] PasteAndGo: Allows you to copy text, paste it to the address bar and load the page as a smooth step.[/li][li] IEView: Allows you to open the current page or a link in Internet Explorer.[/li][li] Flat Bookmark Editing: Tool for managing your bookmarks with greater ease.[/li][li] GooglePreview: Inserts thumbnails of web sites into my Google search results.[/li][li] Web Developer: Amazingly useful if you design web pages. See the page to explore the full list of features.[/li][li] EditCSS: Modify stylesheets using the sidebar in Firefox.[/li] Weatherfox: Displays the current weather as small icons in your browser.[/ul]
