The ability to access almost any search engine right from your browser is awesome:
- you have all engines in one place;
- you can switch from engine to engine with one mouse click;
- you save time and space: easy-to-use drop down menu to choose the engine you need;
- you can enjoy quick and easy installation (besides, most of these search plugins work for both FireFox and Internet Explorer);
- you get plenty of search options without making your browser work slower (unlike with many of extensions).

Thanks Ann for the great list of SEO Firefox Plugins, my personal favorites is the Wordtracker plugin!

Don’t forget Groowe.com, which provides many of this in one single toolbar.

Wow. I don’t use any of those, yet I have lots of things installed that I use every day…
Closest I get is the HTML Validator that gives a tick mark at the bottom of the screen for valid pages, and an exclamation mark for warnings or red cross for errors. Clicking on that opens Firebug and YSlow to look at code etc.
ShowIP shows the IP of visited websites, and with one click does various whois related stuff, but these are traditional extensions, rather than toolbars.

Yeah, I don’t have any of them either, and don’t need them frankly. You used an interesting headline with the word:
must-have

Good list. Tbh, I’ve never used the Firefox search option, but I guess I should get used to it.
Hjörtur Smárason on Jul 14, 2008 at 11:46 am
Great list, Ann. I didn’t even realize you could add search engines in there …
Ann Smarty on Jul 14, 2008 at 1:18 pm
@Danny Sullivan: yeah, great addition… but I still think search option allows for more customization.
infoaddicts on Jul 14, 2008 at 2:49 pm
Fantastic list, I need to give some of these a try.
I also use Netvibes it also has some excellent search engines that you can add.
Regards.
Jeff.

I’ve created this feature with predictad.com. Not only do they provide it for free, it also comes with a custom auto-complete that matches my websites content.
I think this is an extremely important features for webmasters wanting to keep a tight relationship with the visitors that matter the most - the ones that are loyal and trust your content.

An interesting list of toolbars bars, but I think installing all 20 in FireFox would be unworkable.
Ditto Rahmat on Jul 15, 2008 at 8:43 am
@John, CMMIW, they’re search plugins not toolbar plugins. I don’t think it will clutter your Firefox current toolbar
Karuvai on Jul 15, 2008 at 4:59 pm
Yeah Ann, It’s must have!
Jignesh Padhiyar on Jul 23, 2008 at 12:15 pm
