Yapta 1.3.0.9 for Ticket Fares
An user review sums up this add on very well: "For the frequent traveler, this add-on by Yapta is essential. Every time you're looking at flights it just shows up and allows you to tag/watch those specific flights, thus avoiding (a) a separate trip to the Yapta site to utilize their very unique service, (b) having to go back again and again to the flight listings and check it. They notify you. You know how some add-ons are kind of complicated and you're not really sure how to use them? Nothing overdone on this add-on. It's simple, it works, and it saves you time. Plus it's not intrusive to your browsing experience. I did find a couple small issues, but no show-stoppers and the folks at Yapta have been responsive. Probably already fixed." But..even if this is very popular with 6,077 weekly downloads, it has only two reviews so far.

Shareaholic 1.4
Shareaholic allows you to share, bookmark, and e-mail web pages quickly via a wide array of web 2.0 social websites without cluttering up your browser. This add on is hugely popular and is even recommended by Mozilla/ Firefox.

Note: I have listed the add ons here which I felt are fine to use, after reading the reviews. Like I mentioned above all the add ons listed below are very popular and has racked in some very valuable comments from its users. Hence am sharing it here. Any add ons which have a huge weekly download and is popular but yet has very feedbacks from its users are not listed here. But it does not necessarily mean that I am right. Its just my belief and it does not mean that readers have to cater to that. All the extensions/ add ons listed above are submitted to the Firefox Addons website by individual developers and it does not necessarily mean that all of them are safe to use or not safe to use. So it is always advisable to read reviews about them before using them and its entirely upto the readers' discretion as to whether to use them or not after reading the reviews carefully. Its always great to use your logic and analytical skills before using them. Each individual add on has a longer description at the Firefox site and user reviews along with the developers' remarks. So choose wisely.
