Quick delete button in search form
This extension prevents Google, Yahoo and Yandex search pages from modifying search result links when you click them. This is useful when copying links but it also helps privacy by preventing the search engines from recording your clicks.
Collector's Note There are a lot of addons that remove the redirect from Google's search results. This is the best because it has been created by Mr. Wladimir Palant, the famous creator of the AdBlock Plus addon. Please note that this addon does not remove the redirects from Google Images etc...
Allows the download manager to also open in a tab or sidebar, and adds some optional display changes.
Allows editing of web page content while in Print Preview mode, prior to printing or saving as HTML or PDF. Compacts the layout and removes unwanted content such as adverts, sidebars and blank pages. Any element can be formatted, hidden or deleted.
The entire page will be fading to dark, so you can watch the video as if you were in the cinema.
Full featured zoom manager with independent page and image zoom modes. Choose from four zoom modes: Default Zoom, Fit-To-Width, Default Zoom + Site Specific or Fit-To-Width + Site Specific. Button style and zoom levels are fully configurable.
Collector's Note Supports fit-to-width in one click(like Opera). The only addon that does so. See also NoSquint which does not have the fit to width function in one click, but can save your settings(which you can set to fit-to-width) and load them everytime you revisit the page.
Adds zoom and rotation functionality for images...
Collector's Note Actually it should be called "Image zoom and rotate". You don't have to leave the page to zoom an image like with some other addons. It creates two context menu entries with submenus that allow you to zoom or rotate an image by a specified amount. The context manu entries show up only when you right click on an image. Smart!
Just another speed dial extension. Fast and easy to use.
Collector's Note The best new tab page out there. Very similar to Opera's start page.
— Open web pages saved with Internet Explorer or other browsers (MHT)
— Save many tabs, video and audio reliably, in a single ZIP file (MAFF)
— Return to the original site you saved a page from, and more!
Show tabs like a tree.
Collector's Note Useful, Delightful! But I am unable to use it because then I am unable to use many other Tab related addons. Tab Kit 2nd edition gives me some of the functions of Tree style tabs and also plays well with Tab Utilities if the settings are set properly.
LeechBlock is a simple productivity tool designed to block those time-wasting sites that can suck the life out of your working day. All you need to do is specify which sites to block and when to block them.
Collector's Note The best addon to block websites that distract you. Lets you set up groups of websites. You can then block either single websites or the whole groupsYou can block websites/groups by time of the day as well. Very feature rich and stable.
http://en.wikipedia.org/wiki/Text-to-voice. TTS gives Firefox the power of speech. Select text, click the button on the bottom right of Firefox window and this add-on speaks the selected text for you. Isn't it brilliant? Audio is downloadable.
Collector's Note I use it to play quotations and poems on websites like QuoteDaddy etc. Quite good.
UnMHT allows you to view MHT (MHTML) web archive format files, and save complete web pages, including text and graphics, into a single MHT file in Firefox/SeaMonkey.
