Are there any cool add on's for Google or Firefox?

Firefox has a sort of app called Greasemonkey,

https://addons.mozilla.org/en-US/firefox/addon/748

it lets you do all sorts of cool stuff, like editing the way youtube looks and allowing you to download videos from it, adding followers on twitter and generally making it do loads more stuff.

This site http://userscripts.org./ should get you started. You can find scripts to help with facebook games or make rapidshare downloading easier, the world is your oyster.

I wrote a greasemonkey script for Fluther. It adds a link to the chatroom and a random question.

It looks like this.

You definitely want AdBlock. If you’re using that and then ever get on a browser without it, you’ll wonder how the internet has changed for the negative all of a sudden.

Then for Firefox, Linkification, About:Tab (not on AMO) and Resurrect Pages are among the major timesavers. And Weave if you often switch computers.

Ah well, I don’t need to name my most esesntial extensions, because I’ve got them in a collection: https://addons.mozilla.org/en-US/firefox/collection/vinnl

@Vincentt, absolutely, definitely AdBlock. Man, I love that thing. I also use the iMacros for Firefox instead of Bookmarks. The iMacros let me go to, log into and start navigating pages… and my macros are usually only about 4 lines long—I don’t know anything about its full capabilities yet.

@johnpowell Good work writing a fluther script mate

Flashblock for Firefox eliminates a lot of unnecessary mess. Flash scripts show up as buttons, you only see the ones you deliberately click.

Wikipedia Lookup Extension sends selected text to Wikipedia with a right-click.
I use Google as my default search engine, so right-clicking text gives me the choice of Googling or Wikipedia lookup.

Dictionary Lookup Extension gives right-click definitions, no need to go to a separate web page.

Xmarks syncs your bookmarks between different computers. Works with Firefox, IE and Safari, Windows, OS X and Linux. Also syncs passwords and profiles if you choose.

FireFTP!! :)

Chrome doesn’t really have any cool add-ons yet and a couple of Firefox ones that were ported over don’t work right.

Firefox though, there are a few add-ons that I love.
Toolbar buttons – Adds a lot of (optional) buttons that base Firefox lacks. It makes customizing the menubar so much better.
Hyperwords – It does so much that you really have to visit their site to find out how cool it really is. Unfortunately, the Chrome version got screwed like a $2 whore in the transition. It’s a little funky to configure at first, but You have to check it out! I don’t know how I surfed without it.
Leet Key – The “leet” function is a bit lame, but I often use it to translate to/from hex, binary, or ROT13, though it has a few other minor uses
Fireshot – Great for screenshots. Has a few nifty features.
Image Zoom – Does what it says
Video DownloadHelper – Best tool of it’s kind that I’ve tried so far.
AdBlock Plus – If you know what you are doing, it has other functionality as well.

@jaytkay If you had HyperWords, you wouldn’t need either of those two lookup extensions. You also wouldn’t need certain toolbars, translator utilities, currency converters, and a lot of other things.

@jaytkay, that Dictionary Lookup Extension all by itself is a GA. Flashblock is nice, too, since you can ‘whitelist’ the sites to allow flash to work by default.

@jerv, oh hell yes to Hyperwords! I just visited the site, and less than a minute into the demo I knew that this was an add-on I had to have. That thing rocks!

I’m intrigued by the tagline you added to AdBlock Plus… what should I know that I apparently don’t?

@jerv Chrome has extensions. But you have to be on the beta or dev build of it.

@Bugabear The operative word there is “cool”.

@CyanoticWasp If you configure it right and make proper use of wildcards, it can also block other things. As a result, NoScript and FlashBlock are redundant, unnecessary, and redundant.

Oh, and also, this isn’t an extension, but you have to check out this feature which I think both have.

Go to e.g. en.wikipedia.org, and then right-click on the search field on the left hand side and select Add a keyword for this search. Set the keyword to e.g. wp, then click on your address bar and type “wp The Netherlands”. Press enter. Tada! It’ll take you to the Wikipedia page on the Netherlands. Adding keywords like “g” for Google, “gi” for Google Images, and, I don’t know, “fl” for Fluther, can save you so much time.

@jerv Check again. Some very nice coders have ported Firefox Add-ons to Chrome. Adblock for example for Xmarks.

@Bugabear The situation is improving slightly, but still not quite there. Besides, after the HyperWords debacle, I am a little harder to convince.
