- My picks for the best Firefox extensions are the ones that customize Firefox in order to make it more user friendly and that make web authoring synonymous with two key words: quick and painless. To augment my picks, you might like to consult the following sites:

If after clicking on the Install link, you get a warning running across the top of Firefox saying:

If you're bugged by the fact that you can't view a web page's source code in Firefox using Windows Notepad (á la Internet Explorer) then you can easily remedy this by installing Mozex which is basically an acronym for Mozilla external (programs). This extension will also integrate Firefox with other external programs in order to enable editing textarea form fields, handle mailto, news, telnet and FTP links and downloads. For more information about these Mozex functions, go to the author's home page. My primary interest in this extension was the Source Code -> External Editor function.

| This extension will place an item in the right-click context menu that will allow you to open the current page in Internet Explorer (assuming that you're using Windows and/or you have Internet Explorer installed). This was intended to be used for loading those occasional pages out there that tend to malfunction in Firefox but it can also be used simply as a web design tool to ensure cross-browser compatibility. After installing, to use IE View:
You can also have Internet Explorer always open when a certain web site/page is loaded in Firefox. To do this:

This extension will easily put Firefox into overdrive by endowing it with a dashboard of over 50 options providing all kinds of highly useful information and various handy tools for web authors. This includes disabling Javascript, hiding images, finding images with no alt attributes, showing block elements, showing block sizes, validating source code, outlining deprecated elements, editing CSS files with real-time preview results and much, much more. This extension is an absolute MUST-HAVE.NOTES:

| Here's another absolute must-have if you're into writing up your own Javascripts and you've found yourself going nuts trying to figure out why they won't work. This extension will help you quickly and easily zero in on Javascript errors and will tell you exactly what went wrong (as opposed to the vague, snippy Javascript error messages issued by Internet Explorer, e.g., 'Object expected'). Quite frankly, I don't know what I'd do without this extension (probably spend a lot of time weeping over my keyboard). NOTES:

If the find-before-you-finish-typing style of the Firefox 'Find' box starts you cursing six ways from Sunday then this extension will bring you guaranteed relief. Just install it and presto— You've got yourself a nice retro-style Find dialog that pops up when you press Ctrl + F on your keyboard and then DOESN'T DO ANYTHING until you tell it to (i.e., click on the 'Find Next' button). This was one of my biggest pet peeves with Firefox and, until I found this extension, I quite often reloaded a web page in Internet Explorer (*gasp*) before using the Find function.

Another major pet peeve of mine with Firefox was the fact that it doesn't save the URL in a comment tag in the source code when you save a web page to your hard drive. For those who don't know, when you save a web page using Internet Explorer (IE), it will insert a comment tag in the saved file's source code indicating the URL that the page was saved from. For example, if you used IE to save the web page you're currently reading, you would find the following near the top of the source code of the saved .htm file:<!-- saved from url=(0048)http://www.ironspider.ca/browsers/extfirefox.htm -->[Note: In case you're wondering, the number appearing in parentheses (0048) refers to the number of characters in the URL.] I find the URL of a saved web page to be vital information as a typical online session for me consists of doing some research, saving several web pages to my hard drive for later reference and then logging off the internet so that I can work offline. Then should I wish to retrieve the URL of any saved web pages, all I have to do is take a look at the source code of the saved web page and there it is. Now with the SaveWithUrl extension, I don't have to switch to IE to save web pages (yes, I used to do this... shame on me... I know...). To use SaveWithUrl:
To retrieve a URL from a saved web page:
After using SaveWithUrl, the saved URL will also appear in the saved page's source code in a <meta> tag bearing the attribute/value pair name="originalURL". Hence, if you saved the page you are currently reading, you would find the following in the source code (right after the <head> tag):<meta content="http://www.ironspider.ca/browsers/extfirefox.htm" name="originalURL">To uninstall:

This is a great little extension that will render a quick word count of any text you select on a web page displayed in Firefox. You may find this useful to keep track of how verbose (or bereft of content) your web pages are so that you can adjust accordingly. And as may or may not have noticed, I tend to be on the verbose side so with that, I'll keep this description short and sweet. [Word count in the above paragraph: 76 words (*chuckle*)...] To use Word Count:

This extension will allow you to open a dialog displaying a list of 140 standard web color names. The list —which can be sorted by name or color— shows the actual color, the officially recognized color name and its associated hexadecimal color code. The dialog also provides buttons to copy the name or the color code to the clipboard and displays RGB values. This is another must-have for any web designer. To use Web Color Names:

Here's an extension that will facilitate customizing the menus that drop down from the File menu bar running across the top of Firefox (File, Edit, View, Go, etc) as well as the Context Menu system that appears when you right-click anywhere within the browser viewport. This is excellent for those who have installed a kazillion extensions into Firefox and now have menus bloated with a lot of unwanted options. To use Menu Editor:
