I'd like to know if I have Windows Compatibility Mode enabled in Firefox.
I've checked the properties for each firefox.exe I have on my computer, but
there is no mention of the compatibility mode. I've also checked the
properties for the shortcut, nothing there either.  Is there somewhere else
to check this?

Forgot to mention I'm using Win2000, and have two versions of Firefox, 3.0
and 3.6.

I'm not sure what you are referring to but I would think this is a
winbloze question, not Firefox.  The version of FF you are using stated
what OS versions it was compatible with in the release notes - I know of
no FF feature/setting which makes it compatible with anything - winbloze
apparently does.

You have a Firefox problem?

HTH,
David McRitchie,   extensions I use are briefly documented on my site

I've been trying to figure out why Firefox uses so much of my cpu power.
Here are some links to websites that discuss unchecking Windows
Compatibility Mode as a way to cut down on excessive cpu usage by Firefox.
So someone out there thinks there is a Windows Compatibility Mode, but I
can't find it on my computer.

David, thanks for the response...but what does it say?  Was this a lesson in
using Firefox and Google?  I'm still trying to figure out how to check for
Windows Compatibilty Mode in Firefox...and why the directions given (in the
links I posted) don't work.

Right-click the Firefox icon, and select Properties.
In the Properties window, select the Compatibility tab.

I believe there is such a thing in Windows 2000, but I am unsure. 
However if you are running Windows XP, if you go to the program and 
right click on the program icon, select "properties" and you will get a 
menu with five tabs. One: "General"; "version", "compatibility", 
"digital signatures", and "summary".

You can get to the program by right clicking the shortcut icon, select 
"properties", and in the "shortcut tab", select "find target"

This is a function in the Windows operating system and is not related to 
the Mozilla products specifically. )TB & FF)  Its function to allow 
older programs to run in the Windows version for which it was designed. 
i.e. If you have an old Windows 95 program, you would click the 
compatibility mode and select Windows 95 from the drop down menu.


If you have downloaded the correct version of Firefox, it will load in 
the correct compatibility mode, and you will not have to worry about it.

I didn't notice any links that you posted

Windows compatibility mode
On Windows XP, sometimes Firefox must be run in Windows 2000 compatibility 
mode.    Right click on your Firefox desktop icon and click on 
Compatibility > change the setting to Windows 2000 > click Apply.[24] 

reference [24] is
FF keeps shutting down on me -- mozillaZine Forums
http://forums.mozillazine.org/viewtopic.php?p=2882218#2882218

The other material I posted was how I found the links in the mozillazine KB

I guess the real question is why did you ask about "Windows Compatibility Mode"
and what are you trying to solve, where did you hear about setting it,
the above forums reference seems to suggest it doesn't need to be set in XP,
I've used Windows 2000 and I never set it.   You said you have Firefox 3.0 and
Firefox 3.6 and I've had both of those  (the current version is 3.6.3).

FWIW,    my previous posting in the thread did eventually show up for me.

The FF shortcut icon which you use to launch Firefox.
This includes icons in the Start menu.

Are you running an  old version of Windows?
Some old versions of Windows do not have this Windows 
Compatibility Mode.

No.

"Compatibility mode" is an Internet Explorer concept. Windows Update 
every now and then downloads the current version of this IE extension.

You can get similar extensions for FireFox. I can't recall their names, 
as I don't use them. Click on Tools > Add-ons > Get Add-ons, and sniff 
around.

HTH
wolf k.

I guess I'm going to have to conclude that there is no compatibility mode
adjustment in Windows 2000.  When I check the properties from any of the
firefox.exe files, or from the desktop Firefox icons, or from the start menu
Firefox tabs...there are only two choices: General, and Shortcut.  From the
start menu, the Firefox properties show General, and Sharing.  And that's
it...no mention of compatibility anywhere.  It must be a WinXp  item.

I'm trying to figure out why Firefox has such high cpu% usage, and I'm sure
that some of it comes from different web sites and their use of java, etc...
But one of the things I've noticed is that just the act of clicking on a
link will shoot the cpu% usage up to 90-98%.  I thought I would check the
compatibility mode issue to see if there was a connection.  Apparently there
is none.

Flash animations are a big user of CPU.  If you have 4 tabs open and
each has 2 Flash advertising banners, the CPU usage can add up.
Install the Flashblock extension and see if this makes a difference.
      

  Flashblock -  https://addons.mozilla.org/en-US/firefox/addon/433

I've used Flashblock and NoScript for quite a while.  I only use my
antivirus manually (at least most of the time)...and I didn't know what a
link checker was until now...I just installed a Firefox extension link
checker.  I'll try it out and see if I can learn something from it.

I was not recommending a link checker.  I thought that perhaps
when you clicked on a link and your CPU shot up to up to 90-98%,
that might possibly be an AV link checker chewing CPU cycles.

Is it consistently shooting up to up to 90-98% ?
Does it vary depending on the link ?

OK, I noew understand what your problem is.

Current Firefox is no longer backward compatible with DOS (which 
includes Win3.x/9x/ME.)

Anyhow, you don't need a Compatibility setting for Windows 2000. 
Compatibility is designed to run some apps as if they were running in 
earlier versions of Windows, namely Win95/98/ME, NT4/SP5, and Windows 
2000. Windows 2000 has a fairly complete DOS (ie, DOS simulator) built 
in, and IIRC runs it by default. Also, W2K is really just NT4/SP5 with a 
handful of bug fixes.

On XP does not run DOS by default, it has to be invoked via 
"Compatibility". The changes from NT/W2K are substantial enough that 
apps written for those OSs may not run properly on XP. The main reason 
for Compatibility mode is games, many of which are so tightly coded that 
even minor chnages in an OS may render them unplayable. I've never had a 
compatibility issue with productivity apps.

Bottom post, please, as I am doing now. Then the post > answer sequence 
flows logically.

FF's high CPU usage has been noticed an all platforms, not only Windows. 
Some people have reported that uninstalling various add-ons cures the 
problem.

OTOH, it may be the hardware and/or the OS. W2K is an obsolete OS, and 
is presumably running on old hardware with a correspondingly old BIOS. 
But people who complain of FF's CPU usage rarely post hardware 
specifics, so that it's a guess that the hardware is the problem.

FWIW, I've never had a CPU usage issue with XP Pro/SP3 running on an 
Intel DuoCore, even though the motherboard's BIOS is now four years old.

I suspect you won't be able to fix the CPU usage problem.

Since the actual question has been made clear,  and that it is high cpu usage
the place to start would be to check your extensions, to see if any of them have 
major reported problems,  and work to resolve the problems it causes.
    If you have Skype,  or  AVG  in particular there may be extensions installed
    that you were not aware of.  But go through the entire list.   Particularly
    note any extensions you have that you don't know what they are, and anything
    in the list that mentions an extension you have.

RSS feeds and autorefresh,  and autoplay  can make things run slower.

The "BarTab"  extension might help if you have a lot of tabs open, or if you
have more than one tab open that has flash files.
