The most popular Firefox Extensions downloads :
- FlashGot
Download one link, selected links or all the links of a page at the maximum speed with a single click, using the most popular external download managers for Windows, Mac OS X, Linux and FreeBSD (dozens currently supported products, see http://www.flashgot.net for details). FlashGot offers also a Build Gallery functionality which helps to synthetize full media galleries in one page, from serial contents previously scattered on several pages, for easy and fast "download all". - NoScript
Extra protection for your Firefox: NoScript allows JavaScript, Java (and other plugins) only for trusted domains of your choice (e.g. your home-banking web site). This whitelist based pre-emptive blocking approach prevents exploitation of security vulnerabilities (known and even unknown!) with no loss of functionality... Experts will agree: Firefox is really safer with NoScript ;-) - Fasterfox, (3.61 stars, 124819 downloads)
Performance and network tweaks for Firefox. Fasterfox allows you to tweak many network and rendering settings such as simultaneous connections, pipelining, cache, DNS cache, and initial paint delay. Dynamic speed increases can be obtained with the unique prefetching mechanism, which recycles idle bandwidth by silently loading and caching all of the links on the page you are browsing. A popup blocker for popups initiated by Flash plug-ins is also included. - Adblock
Once installed, it's a snap to filter elements at their source-address. Just right-click: Adblock: done. Filters use either the wildcard character (*) or full Regular Expression syntax. Hit the status-element and see what has or hasn't been blocked. - DownThemAll!
Why do we have to load a slow external download manager/accelerator, when we can just have DownThemAll inside Firefox? DownThemAll lets you filter and download - literally in a click - all the links contained in any web-page, increasing download speed up to 600%, and letting you pause and resume downloads any time you want, also from previous FF sessions! No AdWare, no waits. Just the files you want, in a click. - Forecastfox
Get international weather forecasts from AccuWeather.com, and display it in any toolbar or statusbar with this highly customizable and unobtrusive extension.
