In my opinion, Firefox is one of the leading web browsers and is second to none when it comes to the sheer number of add-ons.
My definition of an add-on is a non-essential web browser tool that can increase the functionality of the same in relation the needs of the user. In my opinion, these are the top Firefox add–ons to for 2013.
Online advertising waste time and is annoying, not to mention the fact that these can be a source of malware. Adblock is supported by nearly fifty filter subscriptions. The same is available in several languages. And it can be configured to work the way you want it to. Version 2.0 even has a version that allows you to un-filter non-obtrusive and/or desirable ads.
This is a content extraction add on. It can capture image and video files from most websites i.e. YouTube, DailyMotion, iFilm, DreamHost, etc. Version 3.1 even allows you to set things up so that any video that is played on Firefox gets saved in your preferred format.
Allows you to personalize how you view web pages. This one almost did not make it to my top 10 list. This is because the first few versions worked great. Then an update went up that significantly degraded the loading speed of web pages. Thankfully, update 1.71 was able to correct the error.
Flashgot Media has several useful features that I take advantage of, as an ordinary netizen and web developer. First, it allows me to download one, several or all the links found in a single web page with only a few clicks of the mouse. Second, I can also use the same add on to download most video streams even when the same is playing.
Allows you to create, store, toggle between several Firefox “skins”. You can even set things up so that they regularly change. This is extremely useful to avoid boredom.
This allows you to view your download rate without that annoying window that pops up in the middle of the screen. This is very useful for me because I usually download several items form the web at the same time. By utilizing this Add on I do not have to put up with a cluttered taskbar and confusing windows.
