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.

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?

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. http://support.mozilla.com/en-US/kb/Firefox+consumes+a+lot+of+CPU+resources http://www.nofullstop.com/2008/07/16/troubleshooting-firefox-by-running-in-c ompatibility-mode/ http://kb.mozillazine.org/Firefox_CPU_usage I'm sure there are lots of other reasons, but this seemed like a good starting point.

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.

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 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.

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'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 ? >=20 > "Ralph Fox" <-rf-nz-@xn--kba.invalid> wrote in message > news:ttrb16hrvhqsn0uv6knpq4erjb7c1rfcmr@4ax.com... > > On Sun, 13 Jun 2010 22:37:22 -0700, in message > <t8KdnRjVl8ePXYjRnZ2dnUVZ_vydnZ2d@mozilla.org> > > jbclem wrote: > > > > > 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... > > > > > > Flash animations are a big user of CPU.

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. > 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%.

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. http://kb.mozillazine.org/Problematic_extensions 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.
