Firefox made my whole computer slow?

I upgraded to Firefox 6, as soon as I started using it, I realized that everything was starting to get slower. Pages would take a lot longer to open, and 1:00 youtube videos would take an hour to load. (when before it only took a few seconds) I really need help! I tryed upgrading Flash and reader but it really didn't help! Please help me.

I was having the same problem with crashes, and while it seemed related to Firefox I was not sure. There was some evidence from the crashes that it was possibly related to upgrading my Nvidia driver to a 320.** version. The Nvidia support forums seemed to suggest a problem with the latest versions of the driver. Following advice in http://www.tomshardware.co.uk/answers/id-1790345/display-driver-stopped-responding-recovered-560.html I have now upgraded to version 326.80 Beta. The problem seems to have been fixed.

[SOLVED]Whole computer slows down while lots of ongoing I/O operations

Hello
It's an issue bugging me from quite a long time, so finally I decided to share my anxiety :-D
Is it normal that both desktop environment actions (clicks, moving windows around, even moving the cursor) and keyboard input slows down when disk is under heavy load? It happens for example when I try to unpack something from a big archive or load a big file in a program. Whole computer runs then like Crysis on 512MB RAM, for me it's unusable. I think my config is the key here, so here it is:
Linux asus.k50in 2.6.34-zen2-ARCH-20100812-stable-06977-ge2287d6 #8 ZEN SMP PREEMPT Thu Aug 12 20:54:24 CEST 2010 x86_64 Intel(R) Core(TM)2 Duo CPU T6600 @ 2.20GHz GenuineIntel GNU/Linux
GeForce 102M 512MB
XFS filesystem on every partition.
KDE4.5.1 + all available updates.
Thanks in advance for any hints.

* Amount of RAM?
* Do you have a swapfile or -partition?
* What do you see in the output of 'top' when this happens?
* Do your logs tell you/us something?
I have never seen this behaviour. It is normal, f.e. on an older machine that when doing a pacman -Sy, the system is less responsive or that (even on a newer system) when copying large amounts of data from one HD to another that file operations are slowed down. It is not normal that your desktop is affected by this.

Whole computer slows down drastically when network drive is mounted

Firstly, I hope I'm asking this in the right place. I'm using a MacBook with a Time Capsule and a 1.5TB USB drive attached to the Time Capsule as a wireless network drive. Whenever the network drive is connected, my whole computer runs intolerably slowly. Even if no program is actually using files from the network drive and the drive itself is silent and unused, my computer still crawls along agonizingly slowly. Yet if I plug the drive directly into the MacBook there's no problem whatsoever.
Does anyone have any idea what's going on and how I can cure the problem?
In case it counts:
MacBook: running OS 10.6.5, 2.2GHz, Intel Core 2 Duo, 1GB 667MHz DDR2 SDRAM.
Network: 802.11n, WPA2 Personal.
Hard Disk: LaCie, 1.5TB USB 2.0
Thanks in advance for any help you can give me!

Thanks. Away on holiday right now, but will do it as soon as I get back next week.
Out of curiosity, the external drive works fine when connected directly via USB to the laptop. I took that to mean that the problem wasn't to do with the drive, but probably the network. Is it possible there could be a problem with the drive which only shows up when it's used as a network drive?

Firefox crashes when I load any youtube video on the latest version, it not only crashes firefox but my whole computer goes blank and I have to restart, why is this?

Backstory: There are two possible events that could be causing this
1: At some point I may have followed a ''Tinyurl' link that consquently lead me to a youtube video, to which youtube worked perfectly fine before hand, and this is where i witnessed the first crash. Theories into whether this link, previously stated, may have done something to my system have been thought about, but the fact that youtube still works on the latest Microsoft Internet Explorer seems to present the idea of a virus or an error redundant. I own the latest Macfee antivirus software and Ccleaner(running the registry check) and have run them complete with disc defragment and scan disc error recovery along with an additional malware scanner. Nothing seems to have come up on anything. After doing all this, my last resort was System restore and this seemed to solve the problem, mainly because i had an earlier version of firefox. therefore i resisted updating for aslong as possible whenever it told me to update. but the otherday i thought i'd risk it again thinking it may have been a problem alot of people have been having and it would of been fixed, but sadly it hasn't. this lead me to google the problem and was advised to start firefox on 'safe mode' as there may have been a confliction between add ons or plugins with youtube or some thing like that, but sadly that hasn't worked either. The plugins i had installed with it were the ones firefox has told me to get, or recommended and the only two addons i had on firefox was Adblock plus (fanboy subscrip) and Noscript.
Details of what actually happens: go to a youtube link, video loads for about 2 seconds(both video and audio), screen freezes, and flashes maybe once with some small lines across the bottom half of the screen horizontally towards the right corner, then the screen goes blank and makes my laptop dorment, but still running, thus I restart my system.
Sadly now when I system restore there isn't a point far back enough before this problem. So its either i downgrade(which seems to be the only option) or simply stop using firefox, as internet explorer works perfectly fine. however running firefox with no scrip and adblock plus is the ideal browser customisation, which is why this is rather annoying.
so number 1 was the tinyurl theory and i must admit i was abit foolish to follow such a random link, but whats happened has happened.
2: basically there is a major disfunction with the latest firefox that has to with the addons i have included onto firefox and this seems to be causing a terrible effect on my system.
in a nutshell: firefox worked perfectly before upgrading to the new firefox and before i followed this link, the rest of my system is completely normal and virus and error free or so it says, Other browsers seem to work also. safe mode does not cure the problem.
Running on a customised Dell laptop, which is pretty midrange-toprange and hasn't been active long, so it has the general HD video card thats included in all Studio 15 Dell laptops.
any help appreciated.
cheers.

I have had a similar problem with my system. I just recently (within a week of this post) built a brand new desktop. I installed Windows 7 64-bit Home and had a clean install, no problems. Using IE downloaded an anti-virus program, and then, because it was the latest version, downloaded and installed Firefox 4.0. As I began to search the internet for other programs to install after about maybe 10-15 minutes my computer crashes. Blank screen (yet monitor was still receiving a signal from computer) and completely frozen (couldn't even change the caps and num lock on keyboard). I thought I perhaps forgot to reboot after an update so I did a manual reboot and it started up fine.
When ever I got on the internet (still using firefox) it would crash after anywhere between 5-15 minutes. Since I've had good experience with FF in the past I thought it must be either the drivers or a hardware problem. So in-between crashes I updated all the drivers. Still had the same problem. Took the computer to a friend who knows more about computers than I do, made sure all the drivers were updated, same problem. We thought that it might be a hardware problem (bad video card, chipset, overheating issues, etc.), but after my friend played around with my computer for a day he found that when he didn't start FF at all it worked fine, even after watching a movie, or going through a playlist on Youtube.
At the time of this posting I'm going to try to uninstall FF 4.0 and download and install FF 3.6.16 which is currently on my laptop and works like a dream. Hopefully that will do the trick, because I love using FF and would hate to have to switch to another browser. Hopefully Mozilla will work out the kinks with FF 4 so I can continue to use it.
I apologize for the lengthy post. Any feedback would be appreciated, but is not necessary. I will try and post back after I try FF 3.16.6.

WHY, upon installation of Firefox 4, has my computer slowed to a crawl, wasting all my available time?

It happens on Ebay, but gets quicker after a few minutes go by.
It happens on websites, but never seems to speed up.
- both the arrow keys and the mouse are impaired;
My previous edition of Firefox did not affect my speed, but it did not improve speed either. What it did accomplish was to defeat downloads of files, etc., which caused lock-up of my computer's ability to do anything, previously.
My computer laptop is olde ... purchased around 2002, a Compaq with Windows 2000 Professional operating system.
NEVERTHELESS, it worked fine before installation of Firefox 4.

Facebook on Firefox crashes my whole computer

I've got Windows 7 system and for the past week I haven't been able to open Facebook. It crashes before the page opens. I don't get any error messages because it stops working before this. I have to manually turn the computer off and on again as Ctr Alt Del doesn't work either.

Does it have any effect if you disable plugins like Java and Flash?

FireFox knocks the whole computer off the internet

When I am using FireFox(at present 3.6.8) eventually it will stop accessing the internet. I will start getting nothing but "server taking to long to respond" or "can't find www.xxxxxxx.xxx" or "may be to busy", etc... I ahve several others browsers installed also and when this happens, they ALSO exhibit the same problems. I have to wait 5 minutes or reboot the system to re-access the internet. It does not affect my network connection, just access to the internet.
So far, my only solution is to never use FireFox

Reply to Jscher 2000. No that didn't do it. It just locked up again. Darn!

Hi! I downloaded a plug-in that slowed Firefox, even after I removed it. I reset Firefox, during reset my computer went black. Now it won't open. Help!

I downloaded a plug-in (add-on) from Facebook onto my toolbar and it made my entire computer run slowly. I disabled the add-on, removed the toolbar, and everything was still super slow. I went to troubleshooting and hit reset firefox. It was in the process of resetting and my screen went black. I thought it was just the screensaver but after pressing the space bar, screen did not return. I did a hard exit on my Mac and restarted my computer. On my desktop there is now a folder that says "Old Firefox Data". When I try to open firefox I get a message that says "your firefox profile cannot be loaded. It may be missing or inaccessible. I've tried to reinstall firefox as well, only to have the same result. Help!

Do you have JSON backups that Firefox keeps in the bookmarkbackups folder?
If you use the Time Machine then you can try to restore the places.sqlite file.

My external HD of 1TB is not being recognized by the iMac and when after a long waiting period it does, the whole computer becomes extremely slow. Do I need any particular add-on to make it workable?

My external HD of 1TB is not being recognized by the iMac and when after a long waiting period it does, the whole computer becomes extremely slow. Do I need any particular add-on to make it workable?
Before I updated to OS X Mavericks I was using another external disk that was getting disconnected ocasionally so I bought a new ADATA HD710 portable 1TB Drive and moved the files to it. This new drive which is supposed to be OS X Mavericks compatible takes minutes to show the files especially when opening second and third level folders which has made mu iMac unusable
What should I do?

Your Mac should be able to recognize many different types of drives (including Windows-formatted drives) immediately for Reading, provided they are in good working condition and not damaged. There should be no need to transfer to a different type of drive.
If there is no recognition of this drive, see if it can be seen in Disk Utility.
If your aim is to transfer the data on it DO NOT use ERASE or PARTITION as these will completely erase all the information on the Drive.
If the drive is present while the Mac sleeps, it is likely to drop out and not be seen any longer, especially if it is a USB-powered drive.

Why do GarageBand, iMovie, Photobooth, and Hulu and Youtube videos slow down my whole computer?

I have a higher end 13" MacBook Pro running OSX Snow Leopard 10.6.8 that I purchased in August of 2010. About a month ago, I was using iMovie to edit a project when all of a sudden it started responding extremely slowly. Like, near impossible to work on my project slow. The whole computer was lagging, the mouse was unresponsive and I could barely use the gestures on the trackpad to get to different programs. Eventually the pinwheel of death showed up, and I quit iMovie. As soon as it closed, everything returned to normal. I restarted the computer to see if that would help, but as soon as I opened iMovie again, the whole computer started lagging. I then noticed that the same problem occured when I used GarageBand, iPhoto, Skype, and when I watched Hulu or YouTube videos. With all of these programs/sites, everything is running fine beforehand, but when I open them up, chaos sets in. This problem doesn't occur when I use other intensive programs like Photoshop or Illustrator, nor while I'm browsing the web. The only web problems are when I watch a video. Any video. Other than that, web pages are as quick to load as ever, and I can use the computer normally for any other task. This is seriously a problem because I use iMovie and GarageBand for school a lot, and my grades depend on me being able to use these programs effectively. All of these problems have persisted with these apps since that first instance about a month ago, and no significant changes occurred to instigate them. In attempts to solve the situation, I have cleared my cache, freed up space on my drive (I have 56 free gigs out of 320), I have verified and repaired the disk permissions, and I have downloaded the Apple provided Trojan removal tool for Snow Leopard. This seemed to work for about 10 minutes, but the apps and videos quickly started lagging and slowing down my whole computer again. If anyone else has experienced anything like this, I would love to hear exactly what has happened to you and to see what you did to [try to] fix it. Thanks for reading all of this, I need all the help I can get right now. Also, I can't watch The Daily Show or The Colbert Report on Hulu anymore, and it's killing me! Thanks again.

It's very difficult to say without knowing more about your system. There are a number of possibilities. First, your 13" lacks a discrete GPU, so the CPU is doing the work that a GPU would have done as far as decoding video streams, etc. Each video stream will consume considerable resources from the machine, and if you have multiple things running with video streams being decoded (for example, a browser with video Flash or cumbersome animation and iMovie running at the same time), then that may be a factor.
Additionally, it could be that you are memory constrained. You didn't post a picture of the process list from activity monitor or the memory usage stats, but you probably want to look and see what the memory and CPU usage is and who's consuming what. Some applications are pretty inefficient. For example, if you have iPhoto open and have thousands of images, the indexed metadata and thumbnails are all stored in RAM. iMovie pulls in clip thumbnail sets - (and worse, it has to do on-the-fly transcoding video assets from some cameras that don't encode the video using the parameters it expects to make indexing frames easier). Again, this would show up as periodic spikes in CPU activity for the app.
You seem to have plenty of disk space, that's not likely to be a problem.
Check if Time Machine is running. Time Machine introduces a performance impact, but it's exacerbated by the presence of frequently changed large files (e.g., you don't want Time Machine backing up your video projects while you are working on them).
Lastly, you may consider checking the console for error messages. This might reveal background processes that might be bogging down the system, or things like filesystem/disk errors. If there are errors in the filesystem, when you access certain portions of the disk, the OS and applications can slow down or lock-up as a result.

Firefox seems to run much slower after the update. My computer is old. Can I go back to an older version?

Does the new firefox require a better computer than the old versions? My internet has seemed to slow down considerably after updating to firefox 7. Is the new version of firefox the problem, or is it something else wrong with my computer? If it is firefox, how do I go back to another version?

See http://kb.mozillazine.org/Installing_Firefox
The most recent Firefox version for OS X 10.2 and 10.3 is 2.0.0.20.

Firefox cookies make my computer freeze & have to be rebooted

Firefox stopped working on my machine (Windows 8.1), it opened in the tabs I had last used but there was no picture displayed and the whole computer froze, making it necessary to restart by pushing the button. Uninstalling and reinstalling made no difference, so I uninstalled it and just started using Chrome (no problem). When optimising my computer using CC Cleaner, it stopped when trying to clear 'Firefox Cookies', also freezing my whole computer & making it necessary to restart it by pressing the off button. I've tried rebooting in safe mode but the same things happen. Please advise how to locate and delete Firefox cookies. Thank you

Thank you Jscher that solved the problem :-)

Adobe Flash Player 10 when installed closes the whole computer as soon as it is selected to 'play' a video clip from U Tube or any other source, I have uninstalled it and the problem goes away but I cannot play the clip.any answers?

Adobe Flash Player 10, when installed, closes the whole computer when it is used to play any clip from U Tube or other source. I uninstalled it and there was no further trouble but, of course, I cannot view the clip. If I reinstall it the same problem persists. I have contacted my 'computer guru' but his comment is that many of his clients have the same problem but it appears to be a problem with Adobe however many other friends have put in the version 10 Flash Player and have no problems. I do not appear to have any other problems with the computer such as viruses etc and it is scanned very day for such items. I would appreciate any advice you can give as it is very annoying, thanks, RAB

Me too!
On both IE8 and Firefox. Win 7 32 bit on IBM T42 - 1GB ram.
Old laptop I know but the 10.1.x.x Flash Players worked just fine. Problem started with 10.2.152.26 flash player.
Now BBC TV live and iPlayer work just fine, however YouTube does not - audio but no video. Just a black rectangle where the video should be.
Right click to get the menu and "settings" is greyed out. However select the pop-out option and the video plays. Right click on the pop-out and "settings" is available. So deselect "enable hardware acceleration", close the pop-out and refresh the window (F5) and now YouTube videos play. Switch hardware acceleration back on and now they don't.
This video works fine with hardware acceleration enabled. http://www.adobe.com/products/flashplayer/features/video/h264/
These also work. http://www.adobe.com/devnet/flashplayer/stagevideo.html
Something broken in 10.2, I think.

Can't download in Firefox browser only, unless computer is in safemode.

When Firefox is running, the memory usage continues to grow without stopping until windows begin to drag as if I were really taxing my computer and internet, when I'm not. I also cannot download anything through Firefox, unless I reboot my computer to Safe Mode.
I have run through all of the tutorial/knowledge trouble shooting. Cleared all my history cookies, changed folders, removed extensions, disabled plugins, Refreshed Firefox, use the Firefox Safemode. None of it has changed anything.
I can use Chrome to download just fine, even when my computer is not in Safe Mode.
This all seemed to start within the last 4 days or so, and I remember that Firefox made me update about then. My laptop does not have the update and Firefox works fine. I'm currently at a loss. I prefer Firefox, but I have to use a different browser in order to continue working. My business is heavy with internet communication and this has been a nightmare. Until I hear back, I will begin setting up preferences in Chrome. Hope someone can find a solution. [Windows 7prof 64bit]

I'm not sure what you mean by "changed folders," but have you tried this:
'''Clean Reinstall'''
We use this name, but it's not about removing your settings, it's about making sure the program files are clean. As set forth below, this process does not disturb your existing settings. Do NOT uninstall Firefox, that's not needed.
(1) Download a fresh installer for Firefox 37.0.2 from https://www.mozilla.org/firefox/all/ to a convenient location. (Scroll down to your preferred language.)
(2) Exit out of Firefox (if applicable).
(3) Rename the program folder
''(64-bit Windows folder names)''
C:\Program Files (x86)\Mozilla Firefox
to
C:\Program Files (x86)\OldFirefox
''(32-bit Windows folder names)''
C:\Program Files\Mozilla Firefox
to
C:\Program Files\OldFirefox
(4) Run the installer you downloaded in #1. It should automatically connect to your existing settings.
Any improvement?
Note: Some plugins may exist only in that OldFirefox folder. If something essential is missing, look in these folders:
* \OldFirefox\Plugins
* \OldFirefox\browser\plugins
