In Firefox 2 type about:config in the browser address bar press enter and then add the given command into the search box.

Right click and select modify to change these behaviors.

Most will require you to restart the browser to start working.

==================

This works great with those looong threads.

Go to the top or bottom of a page with a single middle mouse button click.

Type about:config in the address bar and hit enter.

In the filter list of the about:config window enter the following:

middlemouse.scrollbarPosition

Right click the entry that comes up in the window and click toggle to change the value to true

Restart Firefox. Then middle click anywhere in the scroll bar area and the page/scrollbar instantly jumps to where you click. Top, bottom, middle or anywhere you desire.

==================

Is there a way to turn off that little pop up thing in the bottom right of the screen that pops up everytime a download is finished saying "all downloads are complete"?

Yes!!!!

Type about:config in the address bar and hit enter. In the filter list of the about:config window enter the following:

browser.download.manager.showalertoncomplete

Right click the entry that comes up in the window and toggle to change the value to false

No more "download complete" window.

==================

Dont ever use the Go button next to the url box?

Set the browser.urlbar.hideGoButton to true and gain a little more space.

==================

Also useful.

How many times have you composed a long post or email message, then accidentally closed the tab or browser and lost all your work. No more!

From the Tools menu choose Options, and in the Main area, select "Show my windows and tabs from last time" from the "When Firefox starts" dropdown.

Then there is the Undo Closed Tabs Button

Tired of going to History & Recently Closed Tabs just to undo a closed tab? Then this extension is for you! This extension allows you to undo closed tabs via a toolbar button, right-click context menu or even a shortcut (Alt+Z).

==================

Open multiple home pages in separate tabs.

Click on Tools > Options > Main tab.

In the space for the url of your home page, follow the url of your present home page with a separator | and follow that with the url of a different home page (and so on, and so on...)

It would look something like this.

Add as many as you like. It will slow down Browser speed but the below add on is an alternative to this.

The Homepage Randomizer add on will open a different home page each time you start Firefox or click the Home button.

==================

Got any more really good ones? Add them here, I am always on the lookout for good about:config tweaks.

What an excellent thread mate.

I have just implemented the middlemouse.scrollbarPosition/browser.download.manager.showalertoncomplete/browser.urlbar.hideGoButton.

I found them all to be very useful.

Cheers mate.

Thread stickied.

Jason posted a tweak here

Right-click anywhere and select New-> Integer. Name it “nglayout.initialpaint.delay” and set its value to “0″. This value is the amount of time the browser waits before it acts on information it receives.

I put that on myself and it made pages come up faster, quite noticeably.

I didn't do the other ones
