Why is Firefox 4 so very SLOW?
Upon installing Firefox 4, I was made painfully aware that the Mozilla people had just released a browser which proceeded to HOG my resources and bring nearly everything on my MacBook Pro to a standstill. Just when I thought Safari was slow, enter Firefox 4, the slowest, clunkiest experience yet. Don't get me wrong. I do like Firefox. Actually, I reverted back to the last version, which works just fine, but hey, Mozilla, if you're going to create a new version of your browser, maybe you should take the time to make it perform better, not kidnap my system's speed.
Not just laptops!. Firefox 4 has my 27" iMac with: {2.93GHz Quad-Core Intel Core i7; 4GB 1333MHz DDR3 SDRAM - 2x2GB; and HALF EMPTY 1TB Serial ATA Drive}, axle-wrapped for 10 MINUTES on startup. Learned immediately after upgrading, must keep FF.app file in top level Application folder. Now, CLEAN install? What does that even mean? Must I rely on Chrome, Safari and (shudder) IE? Has Mozilla reached the max it can do with Firefox??

Question
The first time I start Firefox it is very slow coming up but after it is up and I want another window it fast again. What do I need to do to clean out whatever is clogging it up. edit* The first time you start up any application after turning on your computer is called a cold start, which is why Firefox takes a while to load right away. (I've noticed that future versions of Firefox start up faster on a cold start then Firefox 5.0.1.) Also, a lower amount of RAM could be slowing its start-up down since Firefox is kind of memory hungry.
* As for the second part of your question, press ctrl,Alt, and the delete keys on your keyboard. The Windows Task Manager should start. Go to the processes tab and look for 'firefox.exe'. Right click on the firefox.exe and click 'End Process'. Hit Yes and wait for a minute.
* Then opening Firefox again.
Hopefully this helped somewhat! -
Firefox 12 is very slow to load pages and if two tabs are opening it lags.
Firefox 12 is very slow to load pages and if two tabs are opening it lags. I've tried everything (e.g virus, defrag, I've created a new profile in "run", etc). I've had my router/line etc all checked and after 2 weeks of cleaning/testing etc its all pointing to Firefox as the problem. Please help as it's driving me nuts.
I have the exact same problem.
Not only does it load pages very slowly, sometimes the page will stop for a good 45 seconds and stop loading, only to finish it much later.
Something is wrong with Firefox 12, it shouldn't be this slow.
How is that each version is progressively worse than the one before it?.
Stop releasing so many versions Mozilla, release one that works and build from there. -
My firefox is running very slow, espically when I am typing, scrolling and in many simple activities. On the other hand my internet explorer is going normally like simple browser.

Why is my Macbook Pro very slow to boot and also everything else?
Hi,
When I start my computer, it remains at the silver screen with Apple logo forever. The startup boot is supremely slow.
Even while i am opening applications, the icons keep on jumping at the dock for a long time before the application starts.
The problem started about two months ago however it has worsened a lot recently. This is my etrecheck profile. Hope it helps. Any help will be appreciated.

Any third-party software that doesn't install by drag-and-drop into the Applications folder, and uninstall by drag-and-drop to the Trash, is a system modification.
Whenever you remove system modifications, they must be removed completely, and the only way to do that is to use the uninstallation tool, if any, provided by the developers, or to follow their instructions. If the software has been incompletely removed, you may have to re-download or even reinstall it in order to finish the job.
I never install system modifications myself, and except as stated in this comment, I don't know how to uninstall them. You'll have to do your own research to find that information.
Here are some general guidelines to get you started. Suppose you want to remove something called “BrickMyMac” (a hypothetical example.) First, consult the product's Help menu, if there is one, for instructions. Finding none there, look on the developer's website, say www.brickmymac.com. (That may not be the actual name of the site; if necessary, search the Web for the product name.) If you don’t find anything on the website or in your search, contact the developer. While you're waiting for a response, download BrickMyMac.dmg and open it. There may be an application in there such as “Uninstall BrickMyMac.” If not, open “BrickMyMac.pkg” and look for an Uninstall button. The uninstaller might also be accessed by clicking the Customize button, if there is one.
Back up all data before making any changes.
You will generally have to restart the computer in order to complete an uninstallation. Until you do that, there may be no effect, or unpredictable effects.
If you can’t remove software in any other way, you’ll have to erase and install OS X. Never install any third-party software unless you're sure you know how to uninstall it; otherwise you may create problems that are very hard to solve.
Trying to remove complex system modifications by hunting for files by name often will not work and may make the problem worse. The same goes for "utilities" such as "AppCleaner" and the like that purport to remove software. -
My firefox is running very slow and crashes and the curcular thing at the top keeps spinning
Hi,
Recently my firefox has been running very slow. Its take long to browse all websites and sometimes it takes really long when the circular thing at the top left hand corner keeps spinning.
When that happens; if I click on the page the screen goes white and then says that firefox is not responding so I close it however if I just leave it at the white screen firefox comes back to normal.
Also I noticed when I am using firefox my connection has gone really slow. I have disabled most plug ins im not using and also uninstalled some programs I was not using anymore on my Dell Inspiron 530S. I also have AVG Free Edition and have done a full virus scan. I think I might have spyware or malware on my computer so today I purchased Adaware Pro and am now running a full system scan so hopefully that solves the problem as I have been told that spyware can slow down a computer.
Your help in this matter would be really appreciated.
Thank you
YusufAn easy try would be to clear the cache, sometimes a bad page will be loaded there and each time you go back to the page it uses the cached page. [[How to clear the cache]] Another issue is Anti-virus software doing constant sweeps of the pages you are trying to view.

Firefox 22 running very slow on windows 7 but no problem in linux. Help
Firefox 22 is running very slow ( rather stalling forever) on windows 7.
I tried resetting option from the "Troubleshooting information" menu and also tried disabling "Hardware acceleration" but still having the problem.
Takes almost a minute ( "New window not responding"..) just to try any option..like opening a new tab.
I have same version on linux mint and but FF runs smoothly.Sorry, not an option. As I said, I have binned FF22 and gone back to 21 -- and it works just as fast as it always did, corrupt profile or no corrupt profile.

Why is Firefox about 5 times slower than chrome on same tablet?
Hei, I love the idea behind firefox, but as mobile browser it feels very slow.
Using the zimbra ajax email client, firefox mobile on a powerfull sony xperia tablet z takes 25s to start up, and even then, usage is laggy. Chrome on the same device starts in 5s and works smooth.
About the same results I get with http://tagesschau.de firefox mobile takes several seconds to display the page readably, while chrome gives the wanted results immediately. I even deleted all history and private stuff, and don't use any addons in firefox, as I read at your help pages, but firefox feels far behind in usability compared to chrome.
Best regards,
HeikoAre these numbers pertaining to the first request only. Actually there has been quite a lot of changes in classloader and jasper compiler etc,. in sp4. Infact sp4 is proved to be much faster than earlier versions (Though I donot have exact figures with me, sp4 is faster than sp1). But some times it also depends on the settings like the debug level, type of session(lite or distributed) etc. At this time, as you are using only the defualt set up, I suggest you to try with other samples and verify is sp4 really 7-10 times slower than sp1. And then come up to a conclusion.
After having tested with multiple samples, with the "same parameters" on both the service packs, Still if you feel sp1 is faster or any further queries please get back to the forum. Please provide information about your settings also, so that I can investigate.
Thanks,
Rakesh. -
Firefox is working VERY SLOW the last 5 days(Signature: hang | )
in the last 5 days i am experiencing terrible slowness to load firefox and during its function it loads very slow every page i choose.
Speedy Fox does not help this problem. I've installed Firefox 5.0 on all the computers on our network just to get constant complaints that it is extremely slow. And it is. Taking minutes to load a page that IE loads in seconds. Or never loading a page at all. IE, Chrome and even Safari work well, Firefox is shit.
Firefox has been declining for years. Once the best browser in the world, it is now floundering because of crappy programming and untested releases. I've HAD IT with this bullshit and this weekend will remove Firefox from ALL our business computers and install Chrome.
Way to fuck up a perfectly good browser guys. -
Firefox 7 is very slow in opening webpages as compared o firefox6
As compared to firefox6, this version, ff ver # 7.0.1 is very slow in opening the webpages. It takes a long time to show the webpage. I have tried to disable add ons and did everything i could,but there seems to be a no solution.
The default of the pref network.http.max-connections has been increased from 30 to 256 in Firefox 6+ versions.
Try to decrease the value of the pref <b>network.http.max-connections</b> from 256 to 30 as used in Firefox 3 versions.

You didn't clarify where you were accessing the content from computers icon or one of the other icons (using the cloud)
It's a coincidence. Verify interference using istumbler and try Ethernet
