Why is my Safari running slowly?

In recent months my Safari has been getting slower-it now takes five or ten seconds for my favorite web sites to open.  Firefox opens them instantly, so it must be Safari.  I've been told to remove the cache (but using a 3d party, like MacKeeper); remove plugins (how do I know which ones to remove?); reset Safari (how, and what data will I lose?), etc.  Which, if any, of these, or other actions, should I safely take, and how?  Thanks!

It is a good idea to include the machine type and OS version in your problem posts.
What disk capacity have you? How much is free? How much RAM have you? What applications are you running?

  • Why is my safari running slow after updating my mac?

    My safari is running slow after completing a software update.  I have cleared the cache.  It did not help.

    Please answer as many of the following questions as you can. You may already have answered some of them. In that case, there's no need to repeat the answers.
    Have you restarted your router and your broadband device (if they're separate) since you first noticed the problem? If not, do that now and see whether there's any change.
    If your browser is Safari, then from the Safari menu bar, select
    Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
    and confirm. Any change?
    If you're running OS X 10.9 or later, select the Advanced tab in the Preferences window and uncheck the box marked
    Stop plug-ins to save power
    Any change?
    Quit and relaunch the browser. Any change?
    Log out and log back in. Any change?
    Enable Private Browsing in the Safari menu. Any change?
    Are any other web browsers installed, and are they the same? What about other Internet applications, such as iTunes and the App Store?
    If other browsers and Internet applications are also affected, follow these instructions and test. Any change?
    If Parental Controls is active for any user, please turn it off and test. Any change?
    If only Safari is affected, launch the Activity Monitor application and enter "web" (without the quotes) in the search box. If a process named "Safari Web Content" is shown in red or is using more than about 5% of a CPU, select it and force it to quit by clicking the X or Quit Process button in the toolbar of the window. There may be more than one such process. Any improvement?
    Again, if only Safari is involved, open the iCloud preference pane and uncheck the box marked Safari, if it's checked. Any change?
    Are there any other devices on the same network that can browse the Web, and are they affected?
    If you can test Safari on another network, is it the same there?
    If you connect to your router with Wi-Fi and you can also connect with Ethernet, do that and turn off Wi-Fi. Any difference?

  • Why does my safari run so slow and does not want to download?

    I have an IMac Intel running Mountain Lion and my internet Safari is sooo slow or it just does not download. I had to use my laptop to go to support - here - because my desktop safari is still stuck.

    Try troubleshooting Safari extensions and third party plugins.
    From the Safari menu bar click Safari > Preferences then select the Extensions tab. Turn that OFF, quit and relaunch Safari to test. If that helped, turn one extension on then quit and relaunch Safari to test until you find the incompatible extension then click uninstall.
    If it's not an extensions issue, try troubleshooting third party plug-ins.
    Back to Safari > Preferences. This time select the Security tab. Deselect:  Allow all other plug-ins. Quit and relaunch Safari to test.
    If that made a difference, instructions for troubleshooting plugins here.
    Check download speed here >  Speedtest.net - The Global Broadband Speed Test
    Less than 15Mbps, contact your ISP for upgrade options.

  • Why does my safari run slow with DSL?

    I recently had to change to DSL internet, and my macbook safari does not do well with it.
    I cannot seem to open more than one internet tab at a time, videos do not load, slow loading time for searching.
    Is there a way to fix this to where my safari is not so slow?
    Is it a macbook fix, or should I increase my DSL usage limit?
    My macbook is up to date.

    You will have to call the Internet Service Provider and let them test the line.
    Best.

  • Why is my Mac running slowly

    Can anyone tell me why my computer is so slow.  Even typing suddenly stops on the screen.  Its a Mac OSX desktop.

    Hello, see how many of these you can answer...
    See if the Disk is issuing any S.M.A.R.T errors in Disk Utility...
    http://support.apple.com/kb/PH7029
    Open Activity Monitor in Applications>Utilities, select All Processes & sort on CPU%, any indications there?
    How much RAM & free space do you have also, click on the Memory & Disk Usage Tabs.
    Open Console in Utilities & see if there are any clues or repeating messages when this happens.
    In the Memory tab, are there a lot of Pageouts?

  • Why is Elements 11 running slowly under Windows 8?

    I got a new pc with Windows 8.  All the specs are better than my old one.  But PSE 11 runs MUCH slower than on the old one.  Costco Support suggested I look for an update to PSE 11 to run under Windows 8.  My PSE is ver 11.0.0.0 but it says it is up to date.  Any suggestions?

    The Wacom drivers were up to date but the graphics card did need a new update and that really helped a lot.  I also turned off the Win 7 "ripple effect" that is standard with the Wacom.  It was annoying and I think it also caused a little slow down.
    Thank you!

  • Why is my CS6 running slowly?

    I have a brand new desktop computer that I just had built for me.  PSCS-6, Windows 7, 64 bit, 8Gb of Ram.  When I am using ACR, I find that there is a lag in response on just about every task.  I am also using a brand new Wacom Intuos 4.   The little blue circle (timer) shows up very frequently when I am adjusting exposure, highlights, saturation, etc.  This does NOT happen on my laptop that only has 3Gb of RAM (Win 7 64 bit). 
    Do I have something set incorrectly?  I expected sheer speed and this is dissapointing to me.

  • HT1338 Why doesn't safari run adobe flash player or adobe java?

    I keep getting error messages that both adobe java and adobe flashplayer are out of date.  I try to download the upgrade but it does not remain on the computer for future use.  I have a couple of programs that require these programs.  Are there any other programs that Apple allows me to use that will do the same as the Adobe programs?

    Adobe Flash Player 11.7.700.225
    Apple Java 2013-004 or Java SE Runtime Environment 7 1.7.0_25

  • Why is mac mini running so slowly suddenly when opening programs like Safari?

    Please give me ideas for discovering why Mac Mini is suddenly opening applications, like Safari, so slowly?

    Could be several issues .... First, how much empty space do you have on your hard drive? You need 5GB, min, and 10% to 15% of total capacity would be better. 
    Bring up Disk Utility (on your hard drive in applications/utilities), and repair permissions. Also, do a verify disk. Does the verify disk say everything is OK or does it identify any problems? If it does, fish out either your original OS X disks that came with the system or a retail OS X version, boot, and using Disk Utility (loaded from the menu bar utilities) select your internal hard drive and do a disk repair. Does that complete normally, or with a 'failure on exit' message?
    Do that and post back with results.

  • Since downloading Mountain Lion, why is Safari running very slow? I've check the internet and it's fine.

    Since downloading Mountain Lion, why is Safari running very slow?

    You're going to have to be more specific and include some details.

  • Why is Safari running so slow under Mountain Lion?

    Why is Safari running so slow under Mountain Lion?

    I have other mac's on my home network that are still running Snow Leopard and the are performing well. I wanted to use the iCloud so I upgraded and instantly started experiencing the slow down, to the point of ridiculousness. Other function are mixed some normal speed, others a day on the beach with the spinning ball. Firefox is at full speed, good thought, haven't checked Chrome yet.
    Last night and hooked into a projection unit that adjusted my screen resolution for a presentation and after the event my Mac reset back to the normal settings and Safari launched and is running normal speeds so far. In the past there have been issues with performance speeds and certain resolutions, has anyone had similar luck or is this a fluke?

  • Why do some old Mac programs run slowly in Classic mode?

    I successfully installed OS 9 Classic Mode on an eMac.  At first, some of my old programs (Thinkin' Things, Millie's Math House, both edmark) ran fine, but as time went on they started jerking and freezing as they ran.  I re-started and it continued to do the same thing.  Any ideas on why these programs run slowly like this? 

    I gathered the info you suggested in previous message, but I was wondering if you could help me interpret it.
    Here's what I got:
    In Activity Monitor; System Memory; Page ins/outs = 12277/0.
    Memory is listed as 1.024 MB, with 822.11 MB free.
    I looked under CPU tab in Activity Monitor and did not exactly now what I was looking for.  What should I do with the CPU #'s?
    I opened Console in Utilities & there were any clues or repeating messages.
    The 40 MB hard drive has 9 MB free.
    I ran the 9.2 CD-based educ. software again.  Some does not boot up.  Some run fine.  Others are choppy at times. 
    Anyway, does this info suggest anything to you.  I wonder if it's a compatability issue between System 10.4.11, Classic Mode and the Power PC chip?  Was this common with Classic Mode? 
    I thank you so much in adavance dor any suggestions on how to solve this problem.

    Quit then relaunch Safari. From the Safari menu bar click Safari > Empty Cache
    Try a video.
