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.

Ever since updating to latest version of Firefox it has been painfully slow on my Mac running OS 10.5.8.

Websites just hang, and never get to where they are supposed to go. The status loop on tabs just spins and spins but never loads the site. Go to the same site on Safari and there in a second. It is like dial up slow. Have tried all the troubleshooting tips(reset, delete/re-create profiles, uninstall/reinstall, updated flash) nothing works.
Firefox had been working fine until latest update. What gives?

'''Try the Firefox Safe Mode''' to see how it works there. The Safe Mode is a troubleshooting mode, which disables most add-ons.''

* You can open the Firefox 4.0+ Safe Mode by holding the '''Shift''' key when you use the Firefox desktop or Start menu shortcut.

How do I get my Firefox bookmarks off of my old hard drive (now installed on my new computer as the 2nd hard drive) and into my new installation of Firefox on my new computer?

I had a lovely computer, about 8 years old, running Windows XP; the mother board died; the hard drive was fine.
I now have a new computer, running Windows 7, and I have the old hard drive as my 2nd hard drive.
How do I get my old Firefox bookmarks off the old hard drive and into my new Firefox installation?

You can find your current profile using about:support pasted into the location bar then click on "Open Containing folder. That is where you will want to replace your old files into.
Next find your old profile on your old HD, see
:https://support.mozilla.com/questions/886839
With Firefox down replace the profile files you decide to replace.

Why has my computer slowed after updating with mavericks

i updated to mavericks .since i did this my computer has slowed and i am also getting problems with streaming can i revert back to mountain lion.

how much RAM do you have?
how full is your hard drive?
what apps are you trying to run when things are slow?
do you have any crapware installed, like
antivirus software
defragmenters
"cleaners"
"optimizers"
how long has it been since you updated? Spotlight may be updating, that can take a while, and things may be slow while it does.
Boot into your recovery partition (hold down ⌘R at restart until you see the Apple symbol), go to Disk Utility, and repair your hard drive. While you're there, repair permissions too. OSX Tips Using the Recovery HD
Try a safe boot (hold down shift and restart) : Mac OS X: What is Safe Boot, Safe Mode? . If this works, it means that the problem is with some third-party software you have installed.
Try a test user account: Isolating an issue by using another user account .
That is: if you want, we could try to fix what is wrong. Otherwise, you could certainly go back to ML if you want. How you would get there would depend on how your computer originally came, either with OS installer discs, or with the OS already installed. osx - Roll back from OS X Mavericks ( or any newer OS) to Mountain Lion - Ask Different

Why, when after upgrading Firefox my Yahoo bookmarks won't work? It happens pretty much every time there is an upgrade and it is frustrating as hell!!!

All of the bookmarks are there if I go to bookmarks in the toolbar and click on "go to bookmarks" they are all there. Usually it is a list of folders when you click on the icon and so far refreshing the toolbar or bookmarks hasn't helped. I have also uninstalled and reinstalled the toolbar so far same thing. They work fine in IE but that piece of crap keeps randomly stops working and that is why I have been using Firefox 95% of the time for my home computing.

This is not a Firefox issue, you could try downgrading to version 18 or 17 but Yahoo needs to update their toolbar and they haven't been doing anything to solve issues regarding them except by laying the blame on us.

Why has the browser slowed to a crawl in the last week or so?

I have been using firefox for about 5 yrs now and haven't had to many problems til lately. It started not loading pages and then loading on 2nd try and takes forever to get there in the last week or so. Is there a reason that the browser has slowed so much? I have a laptop with windows 7, very powerful os system, shouldnt be a problem like this, never has been.

Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
Security software that monitors Firefox or files used by Firefox too strictly can also cause such issues.
Your above posted system details show outdated plugin(s) with known security and stability risks.

You've got some Cisco VPN software. Do you need that? You might want to make sure that it is up to date and compatible with 10.9. The same for Google Drive and DropBox.
Try a Safe Boot, which will disable all the third-party extensions. Does that improve matters?

HT1926 I was prompted to install iTunes 11.1.4 this morning. It failed (first time EVER) with the comment that 'msvcr80.dll' was not available. Upon searching for that .dll in my computer, I found it to be all over the place! Thoughts?

I've NEVER had a version update fail. I did go to 'Tools' and download for a manual install of this update as the info screen suggested. It, too, failed. After searching for the 'missing' msvcr80.dll on my computer, I found it all over the place!
Ran a malware & virus scan with nothing evil popping up.
Tried going back to a restore point before a previous update and doing the install. It failed.

1. Apple has posted their solution here: iTunes 11.1.4 for Windows- Unable to install or open - MSVCR80 issue.
2. If the Apple article does not fully resolve the problem for you, then try Troubleshooting issues with iTunes for Windows updates - MSVCR80.

When I start Firefox, my computer slows to a crawl; the problem is that between every operation, the disk reads/writes for about a minute.

I have an old (~6 yrs) HP laptop running Win XP. I've scanned for viruses, deleted temp files, etc, and defraged the hard drive. After doing a fresh boot, all works OK until I start Firefox (3.6.6), and then every mouse click sends the hard drive into read/write mode for up to a minute. Just writing this memo has taken eight minutes; going to my bank site and setting up a transfer (about 12 mouse clicks) took 16 minutes (!).
Things other than Firefox continue to be plagued by the same problems, after starting and closing Firefox. Opening an Explorer window can take up to three minutes. Closing Firefox doesn't seem to solve the problem - I need to reboot to do that.
Any thoughts?

Start Firefox in Safe Mode (above). Wait a few minutes, then close Firefox.

Firefox was fine until the last update, now it crashes all the damn time

It never crashed until the update to 9.1, now it just crashes all the time, various sites, just stops no warning, nothing.

These links are of no help whatsoever, Firefox updated itself to 9.1. I have not added any software, hardware or changed a thing since before the update. It only started crashing unexpectedly after the update. Therefore, logic would conclude there's a glitch in the update wouldn't it? I have downloaded and reinstalled it twice since the update and the crashing began. The last time I did this was yesterday, so far so good..I'm keeping my fingers crossed.

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.

My mac has become quite slow and just stops working all of a sudden if 3-4 applications are opened simultaneously with that round mouse pointer.What should I do ?

Please assist me in overcoming this problem.

Hi, this seems like a very annoying problem. Unfortunatly, the community will need some more information to help assist you with this problem. Such as:
1) What programs? Are they resource intensive? I mean, if you are trying to run 4 video games or programs like photoshop and 3dsmax forget about it. And if you have 4 programs ALL attempting to write large amounts to the disk it will yeild a similar result. Usually large amounts of I/O are murder on PC's (by which I mean personal computers...), and of course if you don't have enough RAM its a moot point.
2) What are your specs? How much RAM do you have? What is the size of your virtual memory (page file)?
3) Have you cleared the various caches mac's have? I can't direct you to any good third party programs for mac's but I am sure there is a simple cache cleaner within your system.

Firefox has become extremely slow in the recent times

Firefox suddenly has become very slow. It takes too much time to load all websites and even the typed words and scrolling has a great delay in appearing. It becomes unresponsive very often. I tried reinstalling it and even reset it. Its becoming a pain to use this to surf the net. Please do help!!

I also have found that Firefox has become a dog. I've followed one thread that disabled the plugin-container with no help. 20.0.1 can hang for over a minute and actually hog my entire CPU so I can't even start Chrome! I like my FF plug-ins, but the performance problems of FF 20 are becoming intolerable and no one seems to know what the heck! Chrome does not present the problems and I have been visiting and working at the same websites. If many folks are encountering this mess, I suspect that FF is done for. I have actually found that the Android FF is also tending to slow down my smartphone - stall it! I am a few days away from just removing FF from my computing life.

I cannot use a website I need to use, with Firefox 5.0. So, I need to uninstall and go back to 3.5 or 3.6. Please advise. Also, my control panel locks up since Windows Explorer has pbms. Which is why I am using Firefox instead. Thanks for any help!

Install Portable Firefox 3.6.x to your hard drive for that one website. It won't affect your current Firefox installation at all. <br />
