V 17 & 18 use minimum of 30% cpu (even with all add-ons disable and safe mode) on MacBook 10.7

I have been having problems since release 17 (at least) with Firefox sucking up CPU. I have 4GB ram and often have multiple programs open, including Firefox with between 5 and 15 tabs / windows. Decreasing the number of open tabs / windows will decrease CPU usage by 2% for each tab / window closed until it hits 30%, then no more improvement. Oddly enough it drops to a constant 25% when Firefox is NOT in safe mode and all my plugins are enabled. But not below.
Help. I love firefox, but it is becoming more and more problematic.

I found a suggestion on this thread: http://forums.adobe.com/thread/912984?tstart=0
that says to turn of the window restore feature in Lion. I turned it off and was able to install AIR and run the AIR application I use.
You can turn off the window restore feature in System Preferences -> General

  • When using Firefox, PDFs won't load natively on Mac Mountain Lion (10.8.2), even when all add-ons are disabled. No issue using Firefox on PC

    Whenever I click on a web link, do download a PDF form, for example, I get this error message:
    "We are sorry, but Adobe Reader is unable to show documents in this browser configuration.
    Please use your browser to download this file and open it in Adobe Reader or Adobe Acrobat.
    To avoid this message in the future, many browsers provide a way to turn off certain add-ons, and some are able to show this document natively. Please contact your browser vendor for more details."
    This problem only manifested recently. I have recently added Adobe CS6, but the problem manifests itself even when this is disabled. Any help much appreciated.

    The Adobe Reader plugin may not be working properly on Mac.

  • Adobe Media Encoder only using single core of CPU (core parking has already been disabled and did not solve the problem)

    I only edit videos every few months and the last time I edited a video was around 6-9 months ago.  At that time, I noticed AME was only using a single core of the CPU and contacted Adobe who instructed me to disable core parking, which worked.  After disabling core parking AME used 100% of all 12 logical cores to process the video and all was good.  Then last week, I decided to edit another video and noticed AME was very slow and checked and it was again only using a single core to process the video, but core parking is still turned off.  By slow I mean that a 10 minute video with the lens distortion correction preset and one video transition effect is estimated to take nearly 3 hours to complete.  For comparison, the GoPro software processed the same clip with the same effects in 20 minutes.  Also, through troubleshooting with Adobe over the last few days, I have also tried downloading previous versions of the software but the prior versions have the same issue.
    The video I'm trying to edit was shot on a GoPro Hero 4 Black with 1080p Wide at 60 frames per second.  The default video format for GoPro is .mp4.   The output settings I'm using when I export from Premiere Pro to AME are H.264 with the YouTube 1080p HD.
    My system:
    ASUSSabertooth X79
    Intel core i7 4930k (6 physical cores, 12 logical cores)
    16GB DDR3 Quad channel RAM
    Samsung 830 SSD 128GB
    NVIDIA GeForce GTX 460 (not CUDA compatible, I know)
    Please ask if you need any additional information to help solve this problem.

    This has been driving me CRAZY... so going over the message boards from 2 to 5 am this morning I found the best explanation I have seen.   The problem is that Adobe Creative Cloud is NOT "Processor Group Aware".  Windows parses any more than 36 cores into "Processor Groups" and while the Pro version of Windows 7 & 8 can handle 256 threads they have to spread them across multiple processor groups.
    Simple Version:  AREA | How many cores does 3ds Max support?
    Microsoft's Explanation:  Processor Groups (Windows)
    Clearly, this is an Adobe Problem... If any engineers are reading this PLEASE review the below and incorporate it into your next build of Creative Cloud!!!

  • Firefox 18.0.1 consuming excessive CPU--both in Standard and Safe Mode--when accessing Gmail

    Firefox 18.0.1 consumes excessive CPU--both in Standard and Safe Modes--when accessing Gmail (in Standard Mode). CPU consumption averages around 56% on my dual-CPU, Windows 7 desktop.
    The only way to stop this from happening it to open Gmail in "HTML" mode. When I open Gmail in Standard mode, a "Loading..." status shows at the top of the page. After about 30 seconds, a error window pops-up within the Gmail page saying that there is a performance problem and provides the option to load Gmail in a limited, "HTML" mode. Clicking the HTML Mode link solves the issue. I've been using Firefox for years and have never seen this issue until now.

  • I am changing from Word to Pages. I have created my custom template with all my styles etc and that is what comes up when I go for a New Document. Fine. How do I get it to use the same Custom Template when I use Pages to open a Word document?

    I am changing from Word to Pages. I have created my custom template with all my styles etc and that is what comes up when I go for a New Document. Fine. How do I get it to use the same Custom Template when I use Pages to open a Word document?

    The template is a document in itself, it is not applied to an existing document whether it is a Pages document or a Word document converted to a Pages document.
    You would need to either copy and paste content, using existing styles, or apply the styles to the converted Word document.
    You can Import the Styles from an existing document and those imported Styles can be used to override the current document's styles:
    Menu > Format > Import Styles
    The process is simplified if the styles use the same names, otherwise you will need to delete the style you don't want and replace it with the one that you do want when asked, then the substitution is pretty straightforward.

  • Spinning Beach Ball of Death.  Even with all programs closed, I'm still using 5 GB of RAM, according to Activity Monitor.  Help!

    Ever since installation of OSX Lion, I've been having freeze-up problems on my early 2011 MacBook Pro.  Increased the RAM from 4GB to 8GB.  Amazingly, when I have Mail and Chrome open, almost all of the RAM is consumed.  Even with all programs closed, I only have about 3 GB of free space.  Any ideas as to what the problem is?

    Mail under Lion (your profile says 10.5) is always busy and doesn't like large email database I hear.
    Chrome and Safari don't clear their history and cache, lack quota on how many days and disk use, so clear those out. This is where I do use CCleaner on Mac as well as Wndows.
    I keep reading from 10.6 on that even closing (quit) does not release memory and threads galour that there are memory leaks that you have to repair permissions, even restart, and poor memory management for many people's systems (often laptops).
    Free RAM is wasted RAM though. Even 3GB seems excessive. This is not OS 9 or 1999.
    but I found that 4-core 4GB RAM was fine except for handling large photo libraries.

    Are there pepes out there using ipads to make group music with children who have profound and multiple learning difficulties? I am and I'd love to share the ideas.
    I am the music teacher in a  Special school in London UK currently working with Drake Music who are a charity that go into schools to enable music making through music technology. Our purpose is to enable a group of 7 children who have profound and multiple learning difficulties to play instruments on the ipads or through the soundbeam and to be able to play and jam together with me underscoring on the guitar. We're having a lot of fun and we're all learning a lot about what can be achieved using the amazing ipad technology. If you're doing a similar project I'd love to hear from you and we can swap notes!

  • When I use Firefox, my email comes thru with only 1/4 showing and is unreadable. what can I do

    Do you think it might be possible that your phone is a 3G instead of a 3GS?  The reason for asking whether this is a possibility is because 3G iPhones cannot be updated any further than ios 4.2.1.  3G and 3GS are very similar in external appearance.  One way to tell the difference is that the 3G cannot record videos in the camera app, while the 3GS can do this.
    Another way to tell is by introducing your model or serial number in the Apple Support page that identifies your iPhone.

  • Add ons disabled. have firefox4. Running extremely slow. Love using firefox but am using chrome right now because of the speed issue.

    When typing it is slow or delayed. When loading web pages it takes forever. I have disabled all add ons. I had no issues with using firefox until I downloaded the new 4 version. I've had to switch to using chrome and I don't like using that but at least I have no speed issues. Please help so I can use firefox again.

  • While being idle online for a few minutes, why does Firefox start cyclically using 50% to 5% CPU resources, with a 10 to 1, hi to lo ratio

    This behavior became apparent after the last couple of Firefox version updates. Current Firefox version is 21.0. My PC is an IBM ThinkCentre running @ 3.0 Ghz Intel CPU with 1.5 Gigs PC3200 DDR ram. With or without any other Windows apps open, whether I'm on line just idling on my home page (Google) or any other web page or entering / receiving data, several minutes into a session, the MS XP pro SP3 task manager shows Firefox cyclically using 50% (and more) CPU resources for 8-10 seconds then 1-5% CPU resources for 1-2 seconds. Closing & restarting Firefox, allows me a few minutes of speedy surfing. My ISP is AT&T 2nd tier DSL with a download thruput of 300 (+) MB (not Mb) / second (altho, most of the time I'm just viewing a web page or idling, without downloading or uploading any data).
    What has changed? My PC & all of its software have remained the same with the exception of MS security updates, Adobe Reader updates, & Firefox updates (without adding any additional plug ins, add ons, etc., with each update).
    What the...! For the past several minutes that I've been inputting data here, the task manager showed a jump of only 13% cpu usage (ever so briefly) by Firefox & only then when I switched between the task manager & Firefox. Intermittent anomalies are gonna be the death of me...
    Well, this is an annoyance, albeit an intermittent one. Ah, I pine for the days when I heard about & believed in "seamless integration"...any thots that might help resolve this issue sure would be appreciated.

    Hello,
    The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
    Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
    To Reset Firefox do the following:
    #Go to Firefox > Help > Troubleshooting Information.
    #Click the "Reset Firefox" button.
    #Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
    #Firefox will open with all factory defaults applied.
    Further information can be found in the [[Reset Firefox – easily fix most problems]] article.
    Did this fix your problems? Please report back to us!
    Thank you.

  • MacBook Air kernel_task using 130 to 150 % CPU overload with fan overheat

    After hours and hours to get a diagnostic for this problem, I have solve it.
    It seems to be a troubleshooting with the Apple ETHERNET to USB adapter used thru an USB Powered hub (A Kensington here)...
    My configuration was:
    MacBook Air 1.8Ghz SSD
    Wireless BT Apple Keyboard (Aluminum) and Mouse
    24" Apple Display (DVI)
    USB USB Powered
    iPod Classic 80 Go used by iTunes and Time Machine for Backups
    __!! Apple Ethernet/USB Adapter !!__
    Canon Pixma USB Printer
    Overload CPU with kernel_task up to 150% was cycling.
    That's the first reason of the difficulty to diagnose it.
    Because the adapter was so hot I couldn't even touch it, I thought it was probably in charge of this mess.
    Reading some forums, it's possible that there's multiple reasons for an overload CPU time by the kernel_task and this is one of these.
    If you encounter messes with kernel_task using an Apple Ethernet/USB adapter, check it first to do anything else.
    Hope to have help you...

    it seems to be temperature issue, i.e. the system tries with the kernel task to avoid an overheating of the cpu/gpu. those guys here

  • Xcode using 100% cpu even with no projects open:  Solution

    Symptom:
    I had a very strange problem with Xcode 3.2.1 on Snow Leopard 10.6.2. As soon as I opened a project, Xcode would start using 100% of the cpu. It would continue doing this even after I closed ALL open projects. Xcode was using 100% cpu (200% actually) even while idle! Xcode would also often hang. I tried deleting Xcode and reinstalling twice. That didn't help. After much searching and trial and error I discovered the problem and the solution:
    Problem:
    I had an SCM entry defined from a previous remote site session in the SCM tab of the Xcode preferences. This site was no longer responding to requests, and apparently Xcode was continually trying to connect. Apparently the preferences were saved across the uninstall even though I used the shell script to uninstall all the developer tools.
    Solution:
    Delete the unavailable repository from the SCM tab in Xcode preferences.
    I hope this saves someone the aggravation this problem has caused me.

  • Late 2008 Macbook Freezes 5 Minutes into use with newly upgraded Mavericks, works on safe mode; help troubleshooting?

    Hi, I have a late 2008 Macbook - I upgraded it from Leopard to Snow Leopard a year ago and things ran relatively smoothly. A friend suggested I try Mavericks after I have been getting a few error messages with snow leopard and was forced to hard restart. I upgraded to Mavericks last night - the installation went smoothly, however Macbook has since begun freezing every time I am using it for more than 5 minutes. I checked some other discussion forums and I wasn't having the same problems as others - Chrome is updated; I don't use Apple Mail; don't have a lot of third party software (I think). I downloaded EtreCheck and ran on both safe mode and normal mode - things seemed relatively normal except I hadn't backed up my time machine (woops). I saw that Sophos was running a lot on start up - I don't use it so I uninstalled it using the developers instructions (Library/Sophos/Uninstall_Sophos) and than trashed the Launch Daemons that were com.sophos...
    So far nothing has solved my problem. My macbook will start in both modes - but only functions in safe mode. It will run smoothly in normal mode for 5 minutes or so - and I am honestly not sure what triggers the freeze. I copied numerous log files to see if someone could help identify the problem (they run through 2 hard shut downs and finally a restart in safe mode) as well as the safe mode EtreCheck report. I can get a non-safe mode EtreCheck if that will be helpful, just let me know.
    Anyone have any advice on what my problem is? Thanks!

    Hi Carolyn,
    Went through step 1 - macbook froze. Went through the second internet plugins trashing - and it froze. It's almost as if it begins processing super slow at some point and then the cursor goes beach ball and eventually I can't do anything. I did another EtraCheck run when I had it started in normal after I erased the internet plugins and I also have the log files that start exactly when it froze up again. See Below:

    Any other advice?

  • (Possible solution found) Can my wife and I use the same Lion DL even with two separate Apple IDs?

    EDIT: Sorry; original search terms didn't give me my answer. I think I found a solution though. Will update whether it works out.
    My wife and I each have our own MBPs, and we each have our own Apple IDs that pre-existed our marriage. Apple doesn't make it easy to have one family account with subaccounts managed underneath this, and we don't want each others iTunes purchases populating our libraries.
    Is it possible for me to DL and install Lion with my Apple ID, copy it to hers, and install it there with my same info yet still allow her to use her own ID for other things? Or will we need separate IDs for each download?
