Czuch Czuckers: I at one time loaded many different extensions since there are a lot of "cool" ones out there - but found out I never used most of them, and probable would not use most of them - so I uninstalled all but 2.

Forecastfox - nice weather related extension - I keep the 5 day forcast in the bottom bar of my browser - A lot of times I only want a quick outlook - like about what tempature it will be this week, or if it looks like rain, and I use this a lot for just quick looks at stuff. (for more details, I use some weather websites & not forecastfox - but I think it can give you more details also - I just already have a couple sites I look at for the details.

BugMeNot - As a tech guy, I visit many sites for things like tips, computer problems, drivers, etc... Some of those sites make you register before you can view answers, or download drivers. Well for sites I know I will probable never visit again, I envoke the BugMeNot - which will 85% of the time log me onto these sites long enough for me to get what I want and leave - without having to register & get on their mailing lists.

Czuch Czuckers: Just one :)

NoScript ( http://addons.mozilla.org/firefox/722/ )

Czuch Czuckers: I have been through every add-on they do (i think lol) and tried alot like BBW.

Now i only really use:

Greasemonkey, for use with hexkids script.

Resizeable Textarea, lets you make the text boxes we type in here any size you want, great for writing large stuff.

Forecastfox, like BBW says, great weather add-on.

del.icio.us, great for storing bookmarks, and also able to access them from any pc.

Gmail Manager, great if you have a Googlemail account.

Perma Tabs, lets you make tabs permanent.

Some others that i use just for fun:

Footiefox, Clear cache button, Colorful Tabs, Fireform, No Go button, Searchbar Autosizer

ßăķëď Äłáşķǻñ: Thanks a lot! You guys have been very helpful!

Czuch Czuckers: The first extension I install is the All-In-One-Sidebar, which gives you an opera-like sidebar where you can put not only history and bookmarks, but everything which is or might be accessible with a toolbar-icon, and load the content in this side panel. Then I install the Web Developer Extension, Forecast Fox, del.icio.us and AdBlock Plus.

Edit: And the wonderful Download Statusbar!
