    Tired of having multiple tabs open just to view your favorite Google services and other Apps like Feedly, Evernote, Twitter and more? Now you can see them right from your Gmail Inbox. Install now or visit www.integratedinbox.com for more info.

    Add-on note

    Indispensable if you routinely use 2 google products out of these 3 : GMail, Google Calender, Google Reader. They are goig to soon add support for more Google products. While it is indispoensable if you use 2/3 google products. It is still vey useful if you use only gmail. [If you've been using STylish to customise Gmail, I suggest that you ditch it and use Integrated GMail - The experience is much better in terms of convenience of use and it taxes your PC's memory by very little in comparison]

    Add-on note

    There are 4 addons in this list to save webpages as pdf. 1.PDF Download(best because it allows you to email the pdf to a designated email ID) 2.Save as Pdf 3.Web2Pdf 4.pdfit. I use PDF Download and Save as pdf both. This is because I have set PDF Download to send the converted pdf to my email address, so I use it solely for that purpose. Save as pdf is the one I use to download pdfs to my computer.

  • ImTranslator: Translator, Dictionary, TTS

    ImTranslator: Translator, Dictionary, TTS

    COMPLETELY REDESIGNED TRANSLATOR FOR FIREFOX ImTranslator translates text, words, webpages between more than 100 languages. NEW: Inline Translator, Dictionary, access to Google Translate, Microsoft Translator. Unique on the fly localization.

    Add-on note

    The most powerful translation addon available. But there is really no need for it if you use gTranslate or Translate this(other addons in this list)..The translation addons on this list are ImTranslator, FoxLingo, Translate this and gTranslate. These 4 addons vary in terms of thoroughness and speed. The more the thoroughness and reliability of the translation, the lesser the speed. So arranging them in decreasing amount of thoroughness and increasing speed we get -- ImTranslator>FoxLingo>Translate this>gTranslate. For a casual user like me who simply wants to understand a foreign page, 'Translate this' offers good balance and convenience of use. [Im Translator and Fox Lingo both are on the list released by Mozilla of addons that slow firefox down at startup]

  • Diigo Web Collector - Capture and Annotate

    Diigo Web Collector - Capture and Annotate

    Enable multi-color highlighter and post-it notes as your reading aids; Capture the page or any portion to share or archive; Save everything online to allow access anywhere.

    Add-on note

    It can save pages to read them later. It can also take a screenshot of either the whole page or a rectangular area in the page(But unlike the Quick Markup screenshot taking addon it doesn't save the screenshot to your computer, it instead uploads the picture to your diigo account), you canb also highlight the text in a page using a highlighter with many colours and save the page to your diigo account with all your highlights [If you use Bookmarklets, then there are two bookmarklets which serve the same purpose - the 'Diigolet' bookmarklet and the 'Post to Diigo' bookmarklet. But the addon does have some functions that the bookmarklets don't have.]

  • Check4Change

    Check4Change

    Check4Change (aka C4C) is a simple extension that allows you to select a part of a web-page, and get notified when it changes.

    Add-on note

    Checks a webpage for changes in an area that you highlight. For example, you can highlight an area of a page that shows you the football score. It will reload only that part of the page at a time interval that you decide and sound an alarm to alert you. Useful inn'it?! Can also be used for important purposes like checking a page for llatest news stories or stock prices or updated weather reports. Oh and it does not slow down your internet one bit(because it refreshes only a very small part of the page to detect changes) !

  • Adblock Plus

    Adblock Plus

    One of the most popular free ad blockers for Firefox. Block annoying ads on sites like Facebook, YouTube and all other websites. Adblock Plus blocks all annoying ads, and supports websites by not blocking unobtrusive ads by default (configurable).

    Add-on note

    Hi there ! I have created this list after trying atleast 1700 different addons none of whch were 'themes'. This list is the distillate of my work. It contains addons that are useful for daily surfing. I have deliberately excluded addons for web developers from this list. In this list, you will not find any of the funky addons that stupid teenagers use to clutter their browser. It contains only the best addons of each type. Some of them are very rare. I have added my own comments where I thought they were necessary. I will keep updating this list further as I try new addons and I welcome any suggestions from you. Hope you find this list helpful............................

    4 points before you read further:
    1.If you use bookmarklets, then you will not need number of these addons. If a bookmarklet is available that does the same job as an addon on this list, I have mentioned that in my description of the addon.
    2.If you do not know how to use addons, I strongly recommend that you learn about bookmarklets by reading this very good article on PCMag : http://www.pcmag.com/article2/0,2817,1436751,00.asp 3.In this list, I have included many addons that do the same thing and explained the differences between them so that you can make a choice that suits your needs. By no means am I suggesting that you should install(and enable) all 166 addons at the same time. Use your brain when you read further. 4. If you do not want to read too much and are familiar with a lot of these addons, then see another smaller collection of addons that I've created with 45 addons only. It is named "The Only Addons you need", and contains the 45 addons that I always keep enabled. If you use that list to install the addons, I suggest that you still read the description of those addons from this collection. Here is the link to the other collection named "The Only addons you need" : https://addons.mozilla.org/en-US/firefox/collections/ChessWriter/al/....................Now to speak about Adblock Plus. The positives - many people consider it indispensible because it blocks most of the irritant advertisements you see on the internet. The negative - Mozilla has declared Adblock as one of the 20 addons that slow down firefox the most at startup. My recommendation - Use one of either Adblock or NoScripts to achieve the right balance between blocking annoyances and keeping browser speed good. If, however you are already using very few addons the you may keep both Adblock plus and NoScripts. To summarise, it is your personal taste which should dictate which one of those two addons you like more. I personally use only NoScripts. Read my comments on NoScripts to make a more informd decision.

  • Ghostery – Privacy Ad Blocker

    Ghostery – Privacy Ad Blocker

    Ghostery is a powerful privacy extension. Block ads, stop trackers and speed up websites.

    Add-on note

    Indispensible. Increases browsing speed by stopping websites like facebook, google plus and about 800 other such culprits from showing you a like or share button on every website you visit. The difference it will make to your browsing speed will be instantly noticeable. You probably do not need it if you're using NoScripts. Even though Mozilla people say that NoScripts slows down firefox, I still use NoScripts because it blocks a lot of nonsense from the web. But if you fing NoScripts' slowness bothersome or you find its settings hard to understand, then install Ghostery and forget. You don't need to make too many settings with Ghostery. Ghostery blocks about 800 odd common annoying scripts that run on various webpages, like for example, the "share on facebook" button you find on nearly every page these days.

  • LastPass Password Manager

    LastPass Password Manager

    LastPass, an award-winning password manager, saves your passwords and gives you secure access from every computer and mobile device.

    Add-on note

    Along with Roboform, the most secure password storage service available. The reason Autofill is not on this list is because LastPass can also fill forms, so Autofill is not needed. btw Lazarus can also do the same. Must have addon.
