Firefox uses too much CPU when displaying flash sites

When I have a site with flash and/or java open, firefox uses minimum 40% of my CPU power, even when I'm doing nothing, when firefox is idle and waiting for input.
P.S. This could be a recent issue, probably related to the newest version of firefox, however I haven't tried downgrading it because I don't have the old version package in my cache. (cleaned it a while ago)

Of course it is, but there isn't much we can do about it, isn't it? Therefore I suggested firefox3, to alleviate things a little (it does it for me). Flash doesn't even work at all for me in Opera, I only get a grey window where the video should be.
Bye, signor_rossi.
The newest version of flash Plugin only works with Opera 9.5 beta. If you want to use flash with the stable Opera find an older version of the flash plug in.
Thanks for the hint, will keep that in mind in the case I will switch to Opera again (used it for a while because Firefox2 scrolling was bad, with 3 it is much better). Besides, there is a new flash version in the repos.

I cannot watch Flash vids because Firefox uses too much CPU.

Firefox has become untenable because it uses too much CPU and disrupts Flash videos.
I've tried disabling or changing the values of plugins. Installing older versions. Nothing helps. It just sucks. It makes me want to pull someone's lungs out.

Everyone has this problem, since Firefox rigged one of its Plug-ins (something to do with crash reports) about 06 months ago, to max out CPU, thereby sabotaging computer performance (including Flash videos).
Why or how they haven't fixed it before now strains belief. I have seen the same complaint everywhere. It is a major fuck-up. People want to abandon Firefox in droves, except that none of the other browsers have decent add-ons like pop-up blocker.
Sort it out, Firefox.

Firefox uses too much cache when commenting in Facebook - 45MB when the text is only 1kB - why?

Firefox uses too much cache when commenting in Facebook. I wrote a comment up to 1000 characters and my PC crawled. I had to wait several times for the text to catch up with my typing. I cleared caches after entering my comment and it freed up 45MB of RAM from the firefox.exe process in Windows Task Manager. Why does Firefox use 45MB when the text is only 1kB?
Another time the firefox.exe process began at 88MB and went up to 250MB whilst writing a comment, reducing to 170MB afterwards. Firefox hogs the CPU too (I tried the CPU hogging tips but none was the solution to this), but the memory usage is the issue because the CPU would not be hogged if less data was being moved or cached.
I accept some slowness on an old 1.2GHz 512MB PC but the facebook issue is much worse than other sites.

Firefox uses too much CPU ff3.6.3 any HELP?

Firefox uses way too much CPU. Running MAC OSX and ff 3.6.3 using "activity monitor" shows Firefox uses typically 96% of my CPU !!
== This happened ==
Every time Firefox opened
== I noticed my computer was getting s- l -o w- e -r

Hello Kr.
This kind of issues are, unfortunately, more common and the we'd like. Thankfully, 99% of the cases are very easy to solve. However, you do need to diagnose what your exact problem is. Do this:
#run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe-mode] to disable all extensions, themes and plugins. If this fixes your issues, be them with RAM or CPU usage, then you know it's a problem with plugins, themes or extensions. Proceed to number 2. If safe-mode doesn't fix the issues, then read bellow, after this list;
#update all extensions, themes and plugins in your Firefox. If this doesn't solve the issues, proceed to the following number;
#disable all extensions, themes and plugins in your Firefox (not running safe-mode). Being certain that, as in safe-mode, the problems you're having have gone away, enable one plugin at a time. You should be certain that you WANT that plugin to be enabled, so keep your overall number of plugins as low as possible. When you encounter the problems, you know you've found a problematic plugin, so disable it for good. Keep enabling all plugins (except problematic ones) until you've gone through them all.
#enable one extension at a time. Again, be certain that you WANT that extension to be enabled, so keep your overall number of extensions as low as possible. Also, try the theme you want to have installed so see if that is what's causing the problem. When you encounter the problems, you know you've found a problematic extension/theme, so disable it for good. Keep enabling all your extensions (except problematic ones) until you've gone through them all;
#you're done! You've fixed your problems with problematic add-ons. If you want to keep using those problematic add-ons, please contant their author for support.
Ok, if disabling all extensions and plugins through safe-mode didn't work to bring Firefox's CPU and RAM usage to good levels, then you have different issue. The most likely scenario is that you have a third party software running on your computer that is messing with Firefox. Do as follows:
#try reinstalling Firefox. No data will be lost. You can get the latest version for free at [http://www.getfirefox.com/ getfirefox.com]. If that doesn't fix the problem, proceed;
#do a virus/malware check on your computer. If this doesn't fix it, proceed;
#disable all software running in the background that you don't want to have running in the background (in windows, this is done by pressing WINDOWS+R in your keyboard, typing "msconfig" (without the commas) and pressing enter. Now, under the "Startup" tab, you can uncheck the software you don't want, and reboot your system for changes to take effect. If you're unsure of what software you want running, ask someone with more experience). If this doesn't fix your issues with Firefox, proceed;
#check your firewall/antivirus/security suite for enabled functions/features that you don't want and/or may be conflicting with Firefox. You'll find that these features are most likely tied to Internet Security features, such as link scanners or URL checkers and the like. If you're not sure they are conflicting with Firefox, simply try to disable them to see whether or not that's true. As long as you don't browse the web with your antivirus completely off and your firewall completely turned off, there should be no problems. If this doesn't solve the issues, proceed to the following number;
#check your operating system security options, mainly advanced options that are not configured by default. While it's very unlikely that this may be the cause of the problem (after all, it's the last item on the list), it's remotely possible. If this doesn't work, proceed to the following point;
#update your modem/router software. There have been some reports that some modem/router software may cause Firefox and other browsers to loose performance and/or stability. If updating doesn't fix your issue, try other versions of the software, if possible. If you need support with this, contact your modem/router manufacturer. If this doesn't help, proceed;
#clean up your OS registry, using appropriate software. Make sure you've followed my instructions correctly, but if this all doesn't work, [http://support.mozilla.com/en-US/kb/Managing+profiles create a new Firefox profile] (this can be temporary, of course) and see if the issues persist. Report here the results, so we can't help you further.

Firefox uses too much cpu

On the Mac, running Activity Monitor, Firefox 3.6.10 (the latest download) shows 68% CPU being used with ONE web page open and 1.12 GB of virtual memory. This is unacceptable. It clogs downloads and is a nuisance in general. Streaming audio breaks up and dissappears. Every time Mozilla updates the browser, it causes more problems.

Hello,
Try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Then perform these steps:
*Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
*In the Firefox options window click the ''Advanced'' tab, then select "General".
*In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox.
*Now, restart Firefox and see if the problems persist.
Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
* [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
* [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
Did this fix your problems? Please report back to us!
Thank you.

Firefox uses too much memory

I've been using Firefox as the default browser on my systems (both Windows and Linux and in 32 or 64 editions) and for some reason Firefox consumes too much memory. Now trust me. I have a very fast machine and so I get very frustrated with this issue as it seems to be a Firefox only issue. Its true that I might have up to 40 tabs open at times but Chrome can handle it Safari can handle it and even Explorer can handle it. Sometimes Firefox's memory consumption peaks to an astonish 3GB of memory which is unheard of. My machine is so fast that I can have up to 10 programs open (Maya, Photoshop, Cinema 4d, Autodesk Suites MySql server and PHP5, MS Office) and still be able to work with them all at the same time, but Firefox crashes suddenly and that is very annoying as I've customized it to my needs adding extensions and making sure all my online baking is done using Firefox. This memory issue is far more noticeable when I'm using Windows 7 64 bits. The same amount of tabs and extensions opened on Linux have no effect on memory and I often switch to Linux just to be able to enjoy a smooth Firefox browsing experience. I've invested so much money into building an amazing machine and it takes 10 minutes of having Firefox running to crash it all completely. I've lost track of the amount of times I've lost my profile and had to rebuild all my customizations but I can stand that. What is beyond my comprehension is the fact that when I'm using Windows XP or Linux the memory used by Firefox is far lower than when I'm using Windows 7 or 8.1 .
Can you help me out? I really love Firefox and would like to keep using it as my default browser but can't afford losing my profile info every time Firefox crashes or having Windows Explorer crashing and losing all the work I'm doing on other software programs.
Much appreciated;
Sam

Are there any tabs reopened from the previous session when this happens?
Do you keep a large history?
You can check for problems with the places.sqlite database file in the Firefox Profile Folder.
*http://kb.mozillazine.org/Bookmarks_history_and_toolbar_buttons_not_working_-_Firefox
*https://support.mozilla.org/kb/Bookmarks+not+saved#w_fix-the-bookmarks-file
You can try to check and repair the places database with this extension:
*https://addons.mozilla.org/firefox/addon/places-maintenance/
Try to create a new profile as a test to check if your current profile is causing the problems.
See "Creating a profile":
*https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
*http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
If the new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

"AdobePDFViewerNPAPI.plugin" uses too much CPU. How to replace it with Preview?

The AdobePDFViewerNPAPI.plugin uses over 250% CPU when I open a dozen of pdf files from the Internet in Safari 7.0.2. The Adobe Read is 10.1.9 as seen from Safari > Preferences > Security > Internet Plug-in > Manage Website Settings > Adobe Reader.
Can I replace the Adobe Reader Internet Plug-in with Preview or anything else using less CPU? (But it's too time consuming to downlog the pdf files and open thme using other tools e.g. iBook, Preview etc.)
Or any solution at all?

Most PDF documents can be read using the built-in support of OS X & Safari. If you remove the adobe or other pdf plug-in files from HD/Library/Internet Plug ins while any web browsers are closed, then Safari should display them.

Using too much CPU!!

Hello there,
Right now my Macbook pro uses too much of CPU. I have 8 GB of RAM 2.9 GHZ Late 2012 Macbook Pro (not retina). I have screenshot of the thing that uses too much of CPU:
It is now 15 minutes from the start of it. But when I quit it. The CPU dropped to 4% total. Should I be concerned about this?
Also now that I quit this. How can I start it up again? I know that it is not recommended.
Also when I opened my Console I got few messages like something : PM Kernel....
I will post a snap shot of that aswell :

mdworker is the process called by Spotlight to index your boot and other drives for searching their contents.
I suggest you run the #12 OnyX routine here, that will reset the caches and restart Spotlight indexing hopefully fixing your issue when it's complete.
..Step by Step to fix your Mac
If you want to reduce the areas where Spotlight looks, use System Preferences.

Firefox uses too much ram

My FIrefox has been using too much RAM as of late. I have followed all the steps in the firefox support page about checking for possible plugins that may or may not be using too much RAM, but after starting firefox in safe mode, there really wasn't much of a difference. Maybe like 5k kb less, but it's still not enough to account for the 1.7million kb that firefox ends up using with one tab open.
I like to leave my pc on for a bit, and sometimes I'll leave firefox running with a tab open while I'm using other applications, but even if i restart my firefox, the RAM usage does not decrease. After closing all applications and leaving only firefox running, it appears to be around 1.5million kb. Only if i restart my whole pc does the RAM usage drop back to normal levels, and then it ramps back up after a period of time.
I would like to get this resolved soon, or at least figure out the cause of this.

HT4101 My ipad says the device uses too much power when I connect my camera

I brought my ipad 2 on holidays and have purchased the camera connection kit. I tried to download my photos and an error message came up saying that the device uses too much power! My ipad is powered up to 100% and I have closed any open files and it still says the same thing? Does this actually work or do I have to return it?

What have you connected to the kit ? The amount of power that is supplied to the kit is limited, and can't be changed - and a lot of card readers and cameras need more power than is supplied to it. If you have connected the kit directly to your camera then does your camera have a setting to enable 'mass storage device' and/or PTP (picture trasnfer protocol or pictbridge) ?

Firefox uses too much memory, gets bloated, and won't respond.

For the past several versions of FF....I have posted here about it's 'behavior' under OS X.
The browser uses too much memory. After a short period of time, it becomes 'bloated', slow to respond, and requiring a 'force quit' to get out of it.
Being as I've posted about this before, for a previous version, and only received feedback from other Mac users experiencing the same thing, and not getting answers or help...I've stopped using it once more. It was a one day trial, and I didn't make it past 6 hours of use.
Welcome back, Safari!!!
