except for shutting down twice while I was installing new printer software.

Yeah, that would be a time when both the CD drive and the hard drive were spinning up at the same time. Make sure any new power supply you put in has as much wattage (marked on the outside of the supply) as the old one, or possibly a little more.

Okay, so while I was away this weekend the version of Firefox on my work computer stopped allowing me to open a new tab by clicking my scrollwheel. Does anyone know where I go to fix that?

I have no idea how this happened, and it's pissing. me. off.

I think that's in Tools->Options->Advanced->Tabbed Browsing.

Nope. Doesn't say anything about scroll wheels.

Is "Select new tab opened from links" checked?

Select new tabs opened from links

When you middle-click on Web links (or hold down Ctrl while clicking with the left mouse button), the links will be opened in a new tab. That tab will not be shown directly; it will be loaded in a background tab. Check this option to load the link in a foreground tab instead, which will show that tab directly.

Also, check your mouse button properties to see if the scrollwheel click is still set the way you had it.

Can't advise you how to check that without more info. My desktop machine did it the default Windows way, then I installed a Logitech mouse, which uses it's own software to configure the device, and my Sony laptop does it a different way, with different software, that co-ordinates with the mushpad.

that is selected; and yet, it's not doing it. Mouse properties have the scroll wheel identified as a middle button. I don't understand! And yes, it's a Logitech mouse.

It does that? ::clicks scroll wheel:: Neat!

Anyway, I'd advise uninstalling Firefox and delete the C:\\Program Files\\Mozilla Firefox folder (or is it a subfolder?? ::dodges ita's krav::). Reinstall Firefox and it should play nice.

Don't ask me how it got broken.

is it a subfolder??

Flux thinking, little Eddie, flux thinking.

It's the wave of the future.

You might want to try creating a new profile first (especially since if the profile is frelled, uninstalling won't help anyway).

I may be wrong, but I think that's what will be accomplished with deleting the Firefox folder only in a "nuke from orbit" kind of way.
