Firefox extensions

Allow Right-Click
Defeat web sites’ right-click prevention scripts. This is not 100% effective on all web sites, such as ones that may use a body OnLoad method, but it will make web surfing just a little more hassle-free.
Alt-Text for Links
Displays links’ destination URLs in a tooltip window. Based on Hiroshi Shimoda’s Popup Alt for Images extension. If a link has a title attribute, then the title will override the URL address.
Always Remember Password
Instructs web sites to always remember your password. Some sites like Yahoo Mail, Hotmail, and banking sites instruct the browser to never allow your password manager to retain your information. If you use a shared workspace, then this is probably not desirable. If you are the sole user, then it’s quite handy.
BugMeNot
Bypass compulsory web registration via Firefox’s right-click context menu. Compatibile with Mozilla and current Firefox releases. Visit bugmenot.com for full details of their service.
ErrorZilla
Changes the default error page from basically having a reload button to having the following choices: a google cache, a coralize link, an archival snapshot from the wayback machine, a ping, a trace route, and a whois lookup.
Ext2Abc
Adds a “Sort” button on the extension manager to arrange your extensions alphabetically. There’s no permanent change to the order, as this had a possibility of corrupting the extension manager’s files.
Google Images Re-Linker
This will let you click the thumbnail images on images.google.com, skip the referred framed page, and jump straight to the full-size image.
GoonMenu
Allows easy navigation through the Something Awful forums via a right-click context menu.
ListZilla
Outputs either a plain text, vB code, or HTML file that lists all installed themes or extensions.
PaNIC
A boss key for Firefox.
Teleflip
Send instant messages to cell phones via Firefox. It uses the free service Teleflip and the freeware SMTP mailer Blat. Currently only compatible with Windows and service areas of North America.
Word Count
Will count the number of words in any text that is selected. Simply highlight the text, right-click, and select “Word Count”. A pop-up window will show you how many words are in that selection.
