Get the best balance of Chrome's UI and FX's extensions. XUL styles, Firefox tweaks, and userscripts are also important, so I'll be releasing screenshots and details later.
Blocks annoying video ads on YouTube, Facebook ads, banners and much more.
Adblock Plus blocks all annoying ads, and supports websites by not blocking unobtrusive ads by default (configurable).
Collector's Note Combined with NoScript and exercising restraint when installing extensions, this helps to keep Firefox as responsive as Chrome. (Single-process nature and slightly higher-latency tab-switching aside) ...as well as further limiting visual clutter, minimizing the need for disabling GIF animation, and improving security on sites marked trusted in NoScript, of course. The MVPS HOSTS file is also suggested to compliment this.
The easy way to download and convert Web videos from hundreds of YouTube-like sites.
Collector's Note Lets you grab any video or audio file an applet is loading via HTTP. Turn off icon animation and combine with my "DownloadHelper - Hide Inactive, Compact Active" userstyle for unobtrusive operation.
The first and only download manager/accelerator built inside Firefox!
Collector's Note Saves a ton of time whenever you want to download all images in an imageboard thread or all MP3s on an artist's free offerings page.
The best security you can get in a web browser!
Allow active content to run only from sites you trust, and protect yourself against XSS and Clickjacking attacks.
Collector's Note Use "Apply these restrictions to whitelisted sites too" in the "Embeddings" tab as an alternative to trying to get NoScript and FlashBlock to cooperate reliably.
Collector's Note Required for the "Linkify", "Popup Window Fixer", "Autocomplete always on", "Try This Search On", "Show YouTube Star Ratings", and "The Cavern Links Checker" scripts I recommend. Install "Userscripts Updater" first and don't forget to set "The Cavern Links Checker" to "onMouseOver Mode" for performance reasons.
Restyle the web with Stylish, a user styles manager. Stylish lets you easily install themes and skins for Google, Facebook, YouTube, Orkut, and many, many other sites. You can even customize Firefox and other programs themselves.
Collector's Note An easy way to apply custom CSS to one page, one site, several sites, all sites, or the browser's chrome itself. I use this with tweaks like "Customize Toolbar window - dynamic columns", "Firefox 2+3 - Slim Extension List", "Firefox 3 - Go button always visible", "Hide "List All Tabs" button", and a few custom tweaks of my own.
The User Agent Switcher extension adds a menu and a toolbar button to switch the user agent of a browser.
Collector's Note Quick access to alternate UA strings for fooling sites which only think they need Internet Explorer or, in concert with NoScript, for making ExpertsExchange think you're GoogleBot so you can see the answers without an account.
Remove or manage a new and uncommon kind of cookies, better known as LSO's.The BetterPrivacy safeguard offers various ways to handle Flash-cookies set by Google, YouTube, Ebay and others...
Latest updates: See bottom link 'version history'!
Collector's Note Use this to prevent circumvention of your CS Lite rules.
Session Manager saves and restores the state of all or some windows - either when you want it or automatically at startup and after crashes. It can also automatically save the state of open windows individually.
Collector's Note Something to shelve your browsing sessions for later and provide backup crash recovery records in case you don't trust Firefox's built-in crash recovery enough.
The extension previously known as GooglePreview. Inserts preview images (thumbnails) and popularity ranks of web sites into the Google, Yahoo, Bing and DuckDuckGo search results pages.
Collector's Note Add site thumbnails to Google results for when you can't remember what a site was called but you remember the general look and feel.
Never lose anything you type into a web form again! Lazarus securely auto-saves all forms as you type, so after a crash, server timeout, or whatever, you can go back to the form, right click, "recover form", and breathe a sigh of relief.
Collector's Note Crash recovery for web forms. Ensures you'll never lose another long blog/forum post due to a browser crash.
StumbleUpon is the easiest way to discover new and interesting photos, videos, web pages and more, recommended by a community of experts. Tell us what you are interested in and we recommend page after page of amazing stuff you’d never expect to see.
Collector's Note When set to icons-only, reduced to the Stumble, Like, Don't Like, and Share buttons, and put on the right end of the address bar, this is the most efficient way I've found to share links with my family and feed generic URLs into my lifestream so I don't risk feeling guilty for puttering around non-productively on the web. I also suggest these additional Userstyles: http://userstyles.org/styles/36077 http://userstyles.org/styles/36096 http://userstyles.org/styles/36076
Shareaholic is the easiest way to share & bookmark great content from anywhere on the web from one simple ALL-IN-ONE add-on. Works with Facebook, Twitter, Pinterest, Google, LinkedIn, E-mail and 200+ additional services.
Collector's Note One icon, positioned like a Chrome "Page Action" for all your sharing, blogging, social bookmarking, and/or URL-shortening needs... except StumbleUpon, but the SU toolbar can be compacted.
DOM Inspector is a tool that can be used to inspect and edit the live DOM of any web document or XUL application. The DOM can be navigated using a two-paned window displaying a variety of different views on the document and all nodes within.
Collector's Note Since I use a different Firefox profile for my web development, this is primarily for when I need to write a new Stylish style or delete a website's "You need to register to read this" pseudo-dialog from the DOM so I can start reading what GoogleBot saw.
Defragments your Firefox "Places" database (history/bookmarks)
This greatly reduces the lag while typing in the address bar and the start-up time.
This extension features configurable automatic cleaning, periodic reminder, and internationalization.
Collector's Note Automatically run VACUUM on the places database so it doesn't get too fragmented. I suggest checking "Hide statusbar icon" and setting "Automatically clean every 25 starts" and "Show the icon after 30 starts since last cleaning".
