Notepad entry (will be updated every once in a while).

Some Add-Ons for Firefox that I use:

• Abduction – Helpful tool to create screen- or webshots.
• BetterPrivacy – Since the methods of datamining get better, one needs better defense.
• ColorZilla – A colorpicker, ’nuff said.
• DNS Prefetch – While Firefox 3.5 will do DNS prefetching to speed up the browsing, you need this little extension with earlier/current versions.
• DownThemAll! – Firefox has no decent download manager? With this, it has.
• Firebug – Very, veeeery helpful when debugging websites.
• Flashblock – Flash is a great way to create interesting content for websites and also a great way to kill memory. Not to speak of annoying banners with SFX. Simply block them by default and activate them when you want them with a simple click.
• Greasemonkey – While I personally only use it on deviantArt, it can be helpful on almost any site. For the popular ones (like most Google services) there are already a lot of tools available that make the browsing more enjoyable/simple.
• Lazarus: Form Recovery – How often did you fill out a long form, only to see the contents vanish to the nine hells, because you took to long, your browser crashed or another error occured. Lazarus remembers them for you, even textareas, which alone outraces the built-in function.
• Read It Later – Before this Add-On I usually had dozens of tabs open with pages I want to read some time, but not right away when I stumble upon them. Usually they stay open forever, since I never find the time and making a bookmark is to much work to do (especially to remove them later). With this Add-On you get  a nice tool that provides a simple way to store and remove them in a seperate bookmark folder and you also get a tool to keep track of them. You could even store them online to use with several computers.
• Redirect Remover – Some sites create links that lead to an internal app first and then to the site you want to go. Some do this for stats, others for datamining,  some to direct you to ads every once in a while or they just do it to please their evil overlord. This tool directs you to the real URL directly.
• Session Manager – Firefox remembers your last session. Session Manager can remember several sessions and lets you load them even partly.
• Torbutton – Well, this is on my to-do list. Doesn’t work out of the box, so I need to dig in more.
• Tree Style Tab – Another way to organize your tabs, especially useful for wide screens.
• Ubiquity – As already said, a great tool. The only two things that it lacks are the integration of external apps (like Thunderbird and Lightning/Sunbird) and that most standard functions lead to non-German services (which I don’t care about in language, but location… I usually order at some-store.de instead of some-store.com for example). But it’s quite easy to extend, if you know a bit programming.
• Web Developer – You can’t really do webdevelopment without this toolbar.

• The Nethnet – I place this a bit seperately. This is a MMOG, using the www as playground. While the idea sounds like loads of fun, I’m not really sure if it is a good idea. Since all is tracked on a central server, it kinda sounds like a big datamining operation. Just my two cents…

Just a few for the moment. I hope some will be replaced by equal or better built-in functions in the future.

Oh and before I get mails that state that Opera can do most of that with build-in features: I do not care!
