After trying over 50 add ons (at once) I finally found some cool
add ons (12) that I enjoy. First in you don't already have it, you are
going to want to update/download the
latest version of Firefox(at least 2.0.0.4) otherwise some of the add ons may not work.

To update goto the Help menu on the top toolbar and click on "Check for
Updates" (according to the Mac). Some of the nest things about the new
version of Firefox is that it was an in-line spell checker (with
several dictionaries/languages available). I recommend installing the
google toolbar with firefox or going to google and downloading it, it
is really quite useful for quick searches. Also the thing firefox had
always done (as far as I know) is the use of tabs. It eats less of you
RAM rather than having several windows open and you can easily flip
through the tabs (Control + Tab)., which now the new Internet Explorer
has, but I have never been a fan of Internet Explorer. Firefox also
has such an open range of add-pns, you are likely to find anything for
your needs (with the exception to real estate, I haven't found anything
for that).
These are not listed in any particular order
10 FoxMarks Bookmark Synchronizer: Keep Your Bookmarks No Matter Where You Are.

A bookmark syncing add on that allows you to sync your bookmarks with
their server (by creating a free account) and retrieve them from any
computer with an internet connection. I have a PC & a Mac, so when
I am switching between the two i.e. I am on the Mac a want the bookmark
from my PC, it's already there. Really cool software, give it a go! 5/5.
9. FoxyTunes: Portal Between Your Browser and Your Media Player
This I use quite a bit. If you listen to music and surf the net, this
is for you. FoxyTunes controls your media player. Once you get your
player going (on internet radio or whatever) you can hide the player
(especially nice for windows users, one less program in the status
bar). It has a full range of controls and also displays test for the
song. The controls are in the status bar at the bottom of Firefox
(where the text "Done" is displayed when a page is loading) I have had
no problems with it yet. 5/5.
8. ForcastFox 0.9.5.2: Tells You The Weather
Weather at the tips of your...er...mouse pointer. This is my favorite
weather program, its quite accurate and very unobtrusive. This add on
has a fairly abundant amount of options. Once again this add-on is
displayed in the Firefox status bar (bottom right corner) and if you
hover
over the earth globe, you get a radar (which can be animated) also you
can change the icons that are displayed. Like mine (as you can see it's
a bit gloomy here) which can also be changed in the Options menu. 5/5
7. Fast Video Download: Download Embedded Videos
There
are several video downloaders out there and I believe this one to be
the best and what this can't download, Download Embedded can. On some
video downlaods they will download as a *.flv and you will need
VLC Media Player to view it (it's free).

Although like I said it doesn't always work but it's a nice tool to have. 3.5/5.
6. Download Embedded: Download Embedded Objects
Basically
you are able to download everything that is embedded into a website -
pictures, flash movies, videos, music, etc. This is a fun one to use. I
have had very little trouble with it downloading any type of media. It
will auto detect when there are embedded objects and the little
"downward-pointing" arrow will appear (to the left of Forcast Fox for
me). Although the website says :
"although this does NOT work on video embedded in flash [ youtube, video.google.com, etc.. ]."
I have found it does work, but you will have to use the VLC Media Player. 4.5/5.
5. ThumbStrips: Visual Web History
Thumbstrips
allows you to view your history in visual thumbnails, allowing you to
visually glance "back" and navigate back to a certain web page. It also
shows the times in which you were there (i.e. "3 mins. ago"). It also
allows you to filer oout certain website to help you find the right
webpage you were at. I sometimes would bookmark the page, but then
either forget to look at it or couldn't remember what the site was
called. But this solves the problem for me, I'll remember what it looks
like. 5/5
4. Split Browser or Tab Catalog: Navigate In A "Split"These two progams do basically the same thing, but it's up to you to see which one you like better:
Split Browser:
It
splits your tabs into sections allowing you to view & navigate
multipe tabs at a time. Quite nice if you have a large monitor, but I
don't think it would be very useful with more than 6 tabs or a smaller
monitor, as the content would be to small for viewing. I knocked of a
point in my rating because sometimes it got confusing on how to go back
to tabs or it I create a new tab, it doesn't split it as well but then
you have two tabs in one of the split boxes. So it can get quite
confusing. Also if you hover in the middle of the top, bottom, or sides
of the split tabs, it will allow you to make the "splitees" around
within the window. You then can select to "gather" the tabs which will
put all the tabs back into their normal view.
Tab Catalog:

This
is my favorite between the two. The main difference though is Tab
Catalog shows all your current tabs in catalog/thumbnail view and you
click on the one you want to use and Split allows you to navigate all
at once. Quite nice if you have a lot of tabs up and you end up
scrolling through all of them to find which on you want. Also the
"catalog" can be pulled up (or turned off) by pressing the F8 key,
which is a major plus. It also allows you to select multiple tabs and
close them at once, but you can't rearrage them, which would be nice.
4.5/5
3. ScribeFire: Blog From Anywhere



Well
basically. it's actually what I am using for this blog. It allows you
to write you blog without even being logged iin. I was able to to do my
blogs very quick. I didn't have to login....browse to editor...etc.
Just type & post! Has nice features allowing linkage and
photo; embedding, as well as trackback URLs, tags, categories.
If you blog, you MUST try it! The box pops up when you click the icon
on the bottom status bar. Very very nice. 5/5
2. FireUploader: Upload faster than the speed of light...not really
Upload
your photos & movies from anywhere. this nifty little add on sits
in your status bar until you click on it to open it. It allows you to
upload videos to youtube, pictures to
facebook,
Flickr,
Box.net (1 GB free storage),
Picassa (Google's albums),
Webshots (Another video blog thingy), and
OmniDrive (also free 1 GB storage). Nice for photo blogging, backing up photos on trips, etc.
1. Save Session: Save Yourself

You
know how sometimes youur computer just randomly turns off and when you
re-open Firefox you have the option of Restoring the Session or Create
A New Session. Well this works the same way, except it you have all
your tabs open and you have to restart firefox or your computer due to
an update of and installation, well you just go to the Edit Menu and
scroll down to "Save Session & Exit" and it will do just that. You
can also go to the Tools menu and just "Save Session" without exiting.
Pretty nifty! I give it a 4/5 because it would be nice to have a save
& restart function.
Extras:
Toolbar Buttons 0.4.1.4: Push YOUR OWN Buttons

Not
necessarily Cool, but helpful, it adds buttons, so that you can
customize your tool bar to do all sorts of shortcuts, like show
downloads, open new tab, enlarge or decrease text size, restart
browser, full screen and lots more. 3.5/5 - would be nice to have
different Icons but still keep the same commands.
Themes:NASA Night Launch: 
An
all out awesome theme. You have to try it and see it. I had a few
problems though, some of the addons I had, I couldn't view some of
their text. 4/5
Extensions:
Stumble Upon Toolbar:

A
really nifty toolbar. Once you have the toolbar you create a free
account and set your preferences, then start "Stumbling" When you click
the Stumble! button on the toolbar it will send you to a random website
that it believes you will like you can either rate it a thumbs-up or
thumbs-down and it will learn what you like and what you don't like.
This is another must for firefox! You can also specify if you only want
to stumble across videos, pictures or news. You can also go into your
account and see what your favorites are at any point in time
(thumb-ups). Try It!
