High CPU & Memory issues - Excessive and unnecessary CPU usage in Firefox for Windows (see also questions1003966 & 998289)

I am using the latest version of Firefox, 32.0.1, on an HP Pavilion dv7-4141sa laptop computer, running Windows 8.1 Pro 64-bit. There should be more than enough power here to run a browser without any problem, yet the computer is regularly being overloaded by the browser's resource usage.

I am currently measuring typical average CPU usage of 45% - with the browser minimised. That is to say, Firefox is not doing any browser jobs - it is not drawing on the screen - but it is using the most CPU of any process currently running. Why?

I am an ex-software engineer, and my understanding of current application development technology is limited, but I think I can say with some confidence that many techniques and software architectures exist that enable the suspension of program activity, or at least its reduction to a very low bare minimum, when the program is not actually carrying out its design function, which is in this case to draw pictures of website data on a screen.

There is a very serious problem here, one which means that I cannot run Firefox all the time, but have to kill it when I am not actively browsing, otherwise other applications cannot run to their full capacity. This is a great pity, because I have committed a lot of effort to making Firefox my primary web tool. It manages all my many bookmarks, contains my secure password manager (LastPass), manages my web security (via NoScript, AdBlock, and FlashBlock), just for a start.

Before any well-meaning moderators or other commenters start down the usual trail of "have you done this, tried that, disabled the other", I should point out that I have followed all the advice I can find, with no positive outcome. This computer is running a fresh installation of Windows, and a fresh installation of Firefox. At the moment I am running a new test Firefox profile.

The latest version of Adobe Flash, 14.0.0.179, is installed but disabled. When it is enabled and in use, Firefox's CPU usage seems high over longer periods, but overall there is little difference. It doesn't look as though the problem can be laid at Flash's door. A few other add-ins are installed, mainly those mentioned above, and Firefox is skinned with LavaFox v2-Green, but I have previously started from a clean installation, which has made little difference after an initial period during which things seemed to be better. Turning off or disabling various add-ons has made no discernible difference.

Just now I turned Flash on, and after a long period with Firefox minimised, Resource Monitor reported Firefox at 8% average CPU and FlashPlayerPlugin at 0.32%. While running a small video, RM reports FlashPlayerPlugin at about 45% and Firefox at 8%. After the video, Flash went back down to around 0.4%, and after a bit more browsing Firefox went to around 17% minimised. There seems little rhyme or reason here, except that Flash does not seem to be the culprit, although Firefox does seem to consume less when fewer tabs are actually active, as you might expect. I just refreshed more than a dozen tabs, and now Firefox is at 30%, but still not back up to the higher figures. Weird.

The CPU usage does vary a lot around the average, but 30% is still a lot for a program that shouldn't be doing anything above the minimum status maintenance, and still puts it at the top of my Top Process Monitor list. (Right now it's gone back up to 45%, without my using it in any way).

I have Telemetry turned on, so presumably Mozilla is recording some of the relevant data.

This is a very serious fault, which is more or less reproducible and which a lot of people seem to be experiencing. Probably more people have it than realise, because most users will not know anything other than that their computer slows down for some non-obvious reason; they may just think it's something to do with the computer itself, not knowing how to use the Resource Monitor and interpret the results.

Oddly, the problem does not seem to occur when running Firefox under Linux Mint 17, where the response is snappy and the CPU usage ostensibly low; I am going to look at this in more detail shortly.

I am not posting here for advice, but for information and as a form of bug report which hopefully other users will see. It will hopefully spare them a lot of effort and time in trying a lot of recommended "solutions" which will not work. The problem is inherent in the software, and can be solved only by Mozilla.

I am willing to supply any diagnostic data requested; as I said above, I have also turned on "Telemetry". However, I will not be trying out any more reinstallation/new-profile/add-on disable-enable-delete cycles unless I am asked to for very specific reasons. Please do not suggest courses of action which have already been mentioned elsewhere on this forum. I have tried them all.

The situation is very disappointing, but I have confidence that the Firefox developers will pin down the fault eventually and engineer a satisfactory solution that makes it viable to leave Firefox open all the time. Even with that restriction, it's still far better than the alternatives.

In mid July, after the firefox update, I had decided to close firefox like I usually do before I open the client for my MMORPG Aion, so I did. I end up not turning on firefox for a few days and when I did my bookmarks were gone as well as my toolbar bookmarks and my history. I start to wonder what happened and then I realised that there was a grey bar at the bottom of my browser stating, "Sync encountered an error while syncing: Unknown error. Sync will automatically retry this action.." I had no idea why this would happen as I never had this problem before so I look at the firefox support database but since I'm quite the greenhorn when it comes to programming there was only so much I could understand. I did try looking for corrupt or locked profiles but I saw none. Now as of today it's going on 2 months since the problem began and just today I recieved the firefox 32.0 update but still have this problem so I'm at my wits end and I not sure if I'll ever get it working again. Also my sync account is the one under the new system I had updated a few days before the problem began it also seems to be working on my other devices. Im lost without my bookmarks please help.

I love Firefox and don't want to use another browser. I frequently get the error "Firefox is already running". I even created a batch file to kill the process so I can re-launch it. There has to be a real solution.

The key to my issue is... I use shortcuts to web sites from my desktop. This is what seems to trigger the error (but not every time). Please don't tell me to stop using shortcuts; that isn't a solution.

I am using Windows 8.1 64 bit Firefox 32.0.1 (had this same problem with all prior versions too)

Any help is appreciated!

This has been nearly mentioned but not quite covered from what I can see.

The problem: "Bookmark this page" (Ctrl D) Yes, but when you want to put it in a certain folder there are problems. You have a little window with some options: Name: Folder: Tags:

Name, obvious. Folder: Here in lies the problem.......

There are two options. 1 a "recently used" list of directories/folders where you have saved recent book marks to, or a FULL LIST.

So you press the one to do the full list.

That window is WAY TOO SMALL to navigate through the folders/structure to find that specific folder for which you are looking.

Is that clear?

Hope someone can help with this.

Why doesn't Firefox give an option for print preview? Every other Mac Application including Google Chrome gives print preview when clicking Print however Firefox has no option for print preview at all. When I click Print all I get is the option to configure what on the page prints but with no preview. Is this a Firefox issue or something I need to do? This is so frustrating as I like to preview what I am printing since not all websites are printer friendly.

Sometimes, for no apparent reason, it works.

Sometimes, it asks my to log in, so I do, but it doesn't seem to believe I've logged in - at least the menu doesn't change.

When viewing videos from YouTube and other sites, if I click the viewer's full screen icon (not Firefox's full screen arrows in the upper-right corner), the video goes full screen but it does so on another OSX "desktop", which takes about 3.5s to do the zoom and slide, during which the video is paused. I know it doesn't sound like a long time, but it is frustrating to have to just sit there and wait for it, when you know it's possible to just pop right into fullscreen on the same desktop with no delay.

Ok, this is weird. While trying it again to confirm behavior for this question, it now goes fullscreen on the same desktop as the browser, which is the desired behavior...

In case it goes back to the slow method, is there a Preference setting or something in about:config that controls this?

The control icons disappear when viewing the https://www.mozilla.org/en-US/firefox/desktop/ (!) page after updating to FX 32.0.1.

If I scroll to the bottom of this page, then scroll back to the top, just prior to reaching the top of the page, all of my control icons in FX disappear. They're still they're, and work, but appear as grey-on-grey so are rendered invsible. The tool tips, etc, all work fine

e.g. - Back button shows as an empty grey circle - RHS of tabs doesn't show close "x" - Open Menu doesn't show up.

It makes using the browser a bit hit and miss!

Closing the browser and reopening it makes the problem go away, but if re-view the above page and scroll down and up again, and it recurs.

I have screenshots, if required ...

TBH, the problem may have existed on FX 32.0, as I hadn't performed the scroll-down and back on this particular page

I am using dual screens and my "main screen" is on the left. Ever since Firefox updated to 32.0.1 on Monday I've been having this issue. Before the update, I would have my main Firefox window opened on the left and, when I click on a link to open a new window, it would open on the right screen. Now, it will only open on the left screen, where the other window is. If I drag the original window to the right monitor and open a link, the new window will open on the right monitor. But once I drag the original window back to the left, new links will open in the left again.

Before if I had this problem, I would simply drag the new window to the right monitor, then back to the left and close it. Then click the link again and it would open in the right. Kind of a work around I guess. But since the update, even this will not work. Any suggestions? Or is this a new function of the updated version? Is there a way for me to go back to the previous version? Any help is appreciated!
