This menulist allowes to spoof the Referer, sent to pages, you visit, to any value, you want. Just create a list of the values, you need, and select as required.

You need at least PrefBar 4.2 to use this one! It won't work with earlier versions!

This one will save the whole page, you are currently viewing, to one big image file. You have the choice to either save in PNG or JPEG format.

Anyone knows the problem. You surf the web, click on a link and it opens in a new window (or tab) and not in the window, where you currently are. Unchecking this button disables most of the ways, webmasters may use to open new windows, and so it's finally your choice, where you want to open links.

I recommend you to hide this one (use "Remove Item" button) after you've unchecked it, to not waste space. You most probably will never want to re-check it and will only need it again, if some other extension, or the browser itself, changes settings.

If you want to decide, if a eBay member is trustworthy, then the best way to do this is to have a look at the neutral and negative feedbacks. This button grabs the eBay nickname from your currently viewed member page or article page and forwards it automatically to the "negative/neutral feedback search engine" of http://www.toolhaus.org/.

This button file contains one button to validate HTML and one to validate CSS using the services of w3c.org. The tabs are loaded in background and PrefBar tries to set the background color of the tab to red for failed and green for passed, so you don't have to switch to the tab to see the result.

This button clears all finished downloads in your download manager.

Have you ever be interested in what software is running on the server, hosting the page, you are currently viewing? Then you need this button! On most servers it at least is able to fetch the name of the server software (Apache, ...) and the name of the operating system (Unix, Linux, ...). Many servers will even tell you which PHP version, MySQL version, ... they are running.

This button will transfer any popup window, that gets opened, back to a "real browser window", by re-enabling menu bar, any toolbar, the sidebar and the status bar. You have to enable PrefBar for popup windows, to be able to use this one.

This one will toggle "Meta Redirects" for the current tab.

This is the same as "File -> Work Offline" and the same as the "plug icon" on the lower right in the SeaMonkey window. As SeaMonkey has this one built in, it's mostly for those browser, which don't have it. But if a SeaMonkey user wants to use this one: It will work there, too.

This button may be useful for web developers or for people, who want to log out everywhere without closing the browser. It kills the current browser session, whithout killing the browser. To do this, it kills all session cookies and all HTTP authentifications.

This button immediately reloads the proxy information, if you have configured your browser for "automatic proxy configuration"

This button prints out a list of all installed extensions, ready for you to copy and paste into forums or wherever you need this information.

Sometimes you see an URL on a website, but it's only text and not a clickable link. This is the situation, where you need this button. Just select the URL and click the "TXTURL" button. A new tab, with the selected URL, will be opened immediately.

This file contains two buttons to modify the URL of the currently displayed page.
The ".." button drops one directory level. So "http://www.example.com/path1/file1.html" gets "http://www.example.com/path1/"
The "/" button drops all directory levels. So "http://www.example.com/path1/file1.html" gets "http://www.example.com/".

This is a Menu, which contains the items "Print", "Preview" and "Setup"
As PrefBar may also be displayed on popup windows, this makes it possible to print those windows easily.
You may also use this as a template for your buttons, as it shows, how to abuse an extlist, to place several commands into it.
