Slow Safari and Firefox with sys. 10.4.11

Since installing sys. 10.4.11 both Safari and Firefox have become extremely slow. Safari can take 25, 30 or more seconds to open a page. I haven't noticed a speed change in other apps. I have a DSL router which serves 4 computers. Sys. 10.4.8 was much faster. Any ideas are welcome.
Thanks.

I've experienced the same thing. Thought it was my DSL ISP and complained numerous times. Went from avg. 2600 kbps down/ 768kbps up to 860 kbps down and 13 kbps up. This range is consistent on all machines on my network, and with both Firefox and Safari. Last night, I hooked up my IBM lap top and re-ran the test: got 2586 kbps down and 457 kbps up on the PC. Now I think my ISP may be correct -- they don't see a problem with the lines. Looking back, the slow down for the Macs coincides with 10.4.11 updates. Tonight I'll begin looking at the Macs to see why they can't connect at the same rate as before the update, and at the same rate as the PC. Any suggestions on how to restore Mac performance?

  • Slow Safari and Firefox

    I have had my iBook G4 for some three years now and have had very few problems with it. Recently my browsers have begun to run very slowly. With most wireless connections, I cannot virtually run the Firefox application because it is so slow to download a single page that it is just not feasible to use it. Safari is slightly faster but not enough. With wired connections they run OK but again not fast enough. Nothing like what they used to be or how other computers run. I have been told to hold the Command Key + Option + P + R and let my machine go through three or four cycles of restarting itself and it would clean things up. No effect! I have also emptied the chaces of both browsers, as well as cleaned the cookies. But nothing has changed yet. I am really frustrated now. Is there anyway someone could help me with this?
    I have 1.33 GHz Power PC G4 and 1.25 GB RAM.

    Ron,
    You can run the cron maintenance scripts by using a freeware utility such as MacJanitor (found on VersionTracker or MacUpdate) which is probably the easiest or you can run them via Terminal by opening Terminal found in your Applications/Utilities/Terminal.app.
    Here are the instructions from Dr. Smoke's excellent FAQ, from the X-Lab, for running them manually:
    "Using your Admin account, you can execute all three maintenance scripts at once, as follows:
    Launch Terminal, in the Macintosh HD > Applications > Utilities folder.
    At the Terminal prompt, type the following, exactly as written:
    sudo periodic daily weekly monthly
    Press Return.
    Type your Admin password when prompted, then press Return.
    All three scripts will run in sequence. There is no visual feedback while the scripts execute. You will know they are completed when the Terminal prompt returns."
    They might take a few minutes to run but that might help significantly if you have never ran them and you sleep your computer at night when the OS normally runs these.
    Here is the direct link to Dr. Smoke's FAQ: "Running the Mac OS X maintenance scripts"

    PS. You appear to have more than enough free disk space available so that should not be the problem.

  • Safari AND firefox slow

    I have problems with both Safari and Firefox being ridiculously slow on certain webpages, up to a point where they won't load at all. Good example is Yahoo webmail. I am back to using a stone age dell laptop when I need to check Yahoo mail. Having browsed this forum it appears that quite a few people have similar issues with Safari and a standard remedy is to use Firefox instead. Won't work for me since I have the very same problems with Firefox .... Can someone help me out with this? THANKS!

    No, the 4.2.2.1 and 4.2.2.2 servers belong to Verizon; they have nothing to do with OpenDNS, which are for any location worldwide; they are not for or limited to non-US locations.
    Are the sites you're having problems with bookmarked, or do you type them in each time? Did you try creating a new user account for testing to see if the problem exists there, too? If it does, that would indicate a system-wide problem. Also, do you have any Input Managers or Application Support items for things that work with Safari that might be causing the problem?
    Compare your TCP/IP settings for your Ethernet connection to those for your Airport Extreme connection and reply with what you have for each one.
    You should also try this:
    1. Quit Safari if it's running.
    2. Go to ~/Library/Caches/Safari and delete the entire contents of that folder.
    3. Go to ~/Library/Safari and remove any of these items that exist there:
    Form Values
    Downloads.plist
    History.plist
    LastSession.plist
    WebpageIcons.db
    4. Restart Safari and test it on those sites and a variety of others to see if the problem is resolved.

  • Slow responce for MAX OS mail, safari and firefox

    Hi,
    I have a puzzeling problem.
    I have a IMAC intel late 2007 nov with 4gb ram and a 1TB harddisk (850GB disk free space)
    With SnowLeopard and have run all software updates.
    My problem is that mail, safari and firefox are running slow. But as I also have Parelles Desktop 6 I checked my Windows connection, and to my surprice my win explorer is running at normal speed. I then thought it was an issue with my Parallels configuration, but everything is set up with "run MAC faster" and I only dedicate 500mb ram for Windows so I stil have 3,5 GB ram for the MAX OSX.
    It is not a boardband issue as I also run a macbookpro on same broardband with no problem.
    I have tried to clean the mac with Macclearner and run antivirus. But still the 3 internet broadband programs Safai Firefox and mail through MAC OSX is runnning slow.
    I hope someone can help me with fixing toe problem.
    Best regards
    Mads

    Mads,
    It's possible your problem is being caused by the very products you are using to prevent problems, in other words the antivirus software and MacCleaner app. OS X does not need any third party maintenance software, in many instances such software tend to create more issues than they solve. I would STRONGLY recommend following the manufacturer's recommendations for removing both apps. Then empty the trash and do some basic trouble shooting using the tools built into OS X. The first thing I'd do is when the computer runs slow already have Activity Monitor open and check to see if a) how much FREE RAM  it has and b) look to see if there are any processes using a large %CPU. Your computer should have at least 500MB of FREE RAM at all times. If it runs low that will slow it down. What tends to use a lot of RAM are browsers, if you have lots of tabs open that will eat RAM like crazy. In that situation manage the amount of open tabs and restart the browser.
    If you cannot track down the issue the next thing to do is restart in Safe Mode, this will clear some caches. It's possible this is your problem one or more have become corrupted. I had this happen just yesterday, I noticed my system was running very slow and did a Safe Mode restart and bingo it's running like a new computer again.

  • Running a presentation via VGA out with Firefox/Safari open. When I hit 'esc' to come out of slideshow, monitor stated resolution too low. Now Safari and Firefox browsers are still open, but I can't see the browser window on either. Ideas?

    If you use Lion, go to Applications/ Mission Control and, if you have more Desktops, as attached, it means you have more, and you must select the one you need for a certain app. If default settings has not changed, this is Control with left / right arrow
    If in Snow Leopard and earlier, you have these settings in System Preferences only. In Lion, you also have some settings in Sys Prefs.

  • Slow, slow, slow ... (Safari and Firefox)

    I have experienced a drastic slow down lately with loading pages and downloading files. For example, it may take 30 minutes to buffer a YouTube video. Even some pages that are almost entirely text take forever to load.
    This seems to be the case regardless of browser (both Safari and Firefox are effected - Sorry, I didn't know where else to post this message). Also, this happens both at home or using other WiFi networks outside. Any advice?

    Welcome to the forums!
    (First, if yours is an Intel Mac, check that Safari is not running in Rosetta, which is enough to slow it to a crawl.)
    Adding DNS codes to your Network Settings, should gives good results in terms of speed-up:
    Open System Preferences/Network. Double click on your connection type, or select it in the drop-down menu. Click on TCP/IP and in the box marked 'DNS Servers' enter the following two numbers:
    208.67.222.222
    208.67.220.220
    (An explanation of why that is both safe and a good idea can be read here: http://www.labnol.org/internet/tools/opendsn-what-is-opendns-why-required-2/2587 /
    Open DNS also provides an anti-phishing feature: http://www.opendns.com/solutions/homenetwork/anti-phishing/ )
    Wikipedia also has an interesting article about Open DNS:
    http://en.wikipedia.org/wiki/OpenDNS
    Whilst in System Preferences/Network you should also turn off 'IPv6' in your preference pane, as otherwise you may not get the full speed benefit (the DNS resolver will default to making SRV queries). If you want to know what IPv6 is:
    This is Apple's guidance on iPv6:
    http://docs.info.apple.com/article.html?path=Mac/10.5/en/8708.html
    Click on Apply Now and close the window.
    Restart Safari, and repair permissions.
    If that didn't do it, then try this as well:
    Empty Safari's cache (from the Safari menu), then close Safari.
    Go to Home/Library/Safari and delete the following files:
    form values
    download.plist
    Then go to Home/Library/Preferences and delete
    com.apple.Safari.plist
    Repair permissions (in Disk Utility).
    Start up Safari again, and things should have improved.
    Less likely, but possible, is that the slowness is caused by a Trojan such as the one called 'DNSChanger' or 'OSZ.RSPlug', which can alter the DNS settings of your network connection. This particular Trojan can be inadvertently installed if you have come across certain Quicktime movies where got a window stating that you have to download and install a particular codec in order to see the video.
    If you have agreed to that installation, your system can be infected and your DNS settings altered, which results in your system using the wrong DNS servers, which can slow web surfing to a crawl.
    This can be fixed by downloading and running a freeware utility called DNSChanger Removal Tool which you can download from here:
    http://www.versiontracker.com/dyn/moreinfo/macosx/33696
    Once you have run that utility you have to re-boot your Mac, then reset Safari, and re-enter your DNS settings in System Preferences/Network.

  • Problems with Safari and Firefox (HTTP?)

    Problems with Safari and Firefox (HTTP?)
    On a laptop G4, 10.5.8 and Safari 5.02 I experience the following:
    On the account of my oldest daughter everything works fine, i.e. wireless internet works and no problems with mail or safari.
    On the same laptop, on the account of my other daughter, the wireless is OK, she can mail etc. But safari nor firefox works. It says: can’t find server (whatever site) and in the activity window it looks if safari tries to open files (in the safari preferences-folder) in stead of http. Same applies to Firefox, so maybe it has more to do with HTTP in general?
    What goes wrong? What to do? I tried the following on the host terminal (tips from Apple)
    defaults write com.apple.safari WebKitDNSPrefetchingEnabled -boolean false
    and
    defaults delete com.apple.safari WebKitDNSPrefetchingEnabled
    but that did not help,
    Nanne

    I'm still wondering why it happens now at this moment in time...
    PC does seem to be a bit odd & inconsistent, the few times I've tested with it, at least so far as we content filtering goes; and if I remember rightly, you're not the first to report previously ok settings suddenly preventing some or all internet until pc is switched off altogether.
    It may work when re-enabled

  • How can I correct the problems I've been experiencing lately  with drop-down menus in general as well as and leading of text. It 's occurring  on both Safari and Firefox browsers.

    The above headline pretty much covers the problems.
    Access to the drop down menus is erratic.  Sometimes it's problem-free, but at other times it's impossible to see the options on the menu, or if they are visible, it's impossible to effect a change by clicking on one of them.  The times I notice it most is when I am trying to change fonts or font sizes, but  it occurs at other times, as well.
    It's also frustrating to have to deal with double spacing (for example, when describing items on eBay).  Sometimes the text flows  normally,  but if I force a  return, the text that follows usually is double-spaced.
    Often,  the justification option does not work either.
    Occasionally, I can  get around one problem or another by switching back and forth between Safari and  Firefox, but eventually, the original problem resurfaces.
    Because it happens on both browsers,  eBay tech support is inclined to think the problem is in my software. (I'm inclined to agree.)
    Although they have suggested clearing  the history in FF, that option must have been relocated, because  it'sno longer under the "Tools"  menu, where it was  in the past. I also can't find  the clear  your cache option on OS Safari or 10.8.3.

    I don't think it'd help much but clearing history is now in the History menu, and setting FF to clear history on exit is near the bottom of the Privacy tab of FF Preferences.
    Also, if you don't have the Develop menu in Safari, open Safari preferences, click Advanced, and select “Show Develop menu in menu bar.” You'll find "Empty Caches" there.

  • Safari and Firefox seem to have issues with Flash?

    Hi - in the past few days every time I try to view a website with video, both Safari and Firefox hang with the beachball and I have to force-quit. I tested to see if it was just taking a long time to load, and it was still the same after an hour. I've read on this forum that Snow Leopard and Flash have some issues, and I've done everything suggested: un-installed Flash then re-installed the latest version, cleared out Safari cache and reset Safari, repaired disk permissions...I am at a loss. Any ideas are appreciated!

    Hi,
    Go here for trouble shooting 3rd party plugins or input managers which might be causing the problem.
    http://support.apple.com/kb/TS1594
    Make sure Safari is running in 32-bit mode. Right or control click the Safari icon in the Applications folder, then click: Get Info In the Get Info window click the black disclosure triangle next to General so it faces down. Select 32 bit mode. Also, (in that same window) make sure Safari is NOT running in Rosetta.
    If Safari still crashes, go to the Safari Menu Bar, click Safari/Preferences. Make note of all the preferences under each tab. Quit Safari. Now go to ~/Library/Preferences and move this file com.apple.safari.plist to the Desktop. Relaunch Safari. If it's a successful launch, then that .plist file needs to be moved to the Trash.

  • Constant & erratic "Page Load Error" with Safari and Firefox

    A week or two ago, I started getting constant "Page Load Errors" ('this page cannot be found', etc) when browsing with either Safari or Firefox. These are not dead sites that time out, but are very live (and cannot be summoned no matter how many times refresh)!
    Something is wrong on my computer's end: I have strong wireless, have tried connecting with ethernet, and have used a different network. All of these produce the same result, where about half of the sites I try to connect to are instantly declared as dead by any browser I use.
    I am not using any firewall, and have emptied both browser's caches.
    Any ideas would be greatly appreciated.
    Thanks!

    I'm having the same problem. It only happens at home over my DSL connection. Here is what I have tried and the results.
    This really started bothering me since I upgraded to a recent Macbook Pro. I tried my original MBP with Leopard and found it doing the same thing. I ended up testing from my G4 and it works fine. The problem occurs over wireless and wired. I tried changing my MTU size with no change. I thought it was DNS but changed to other DNS and it didn't make a difference. Happens in Safari and Firefox. I am thinking it has an effect on iTune store also. The problem goes away when I VPN in to work, comes back when I close the VPN.
    Just tonight I installed an clean 10.5 Leopard on my original MBP. Safari works perfectly. Instead of updating to 10.5.6, I download the 10.5.5 update. After updating the problem reappeared.
    Again, my G4 with latest Tiger update work fine and both Macbook Pros with the latest Leopard have a problem over my DLS connection. They work perfectly fine at work and other locations.

  • Safari (and Firefox) freezing on all pages with embedded video

    Hi, is anyone else experiencing this problem? Any pages with video, with the exception of YouTube, have been freezing on both Safari and Firefox (Hulu, etc.). They don't load and I have to force quit the applications (and, of course, not watch video). Is anyone else having this problem? I've repaired permissions, emptied the cache, delete the plist file, and it's still happening.
    Anyone else having this problem? Any solutions? All help appreciated. M

    I was having a problem with Safari and Firefox and Camino quitting when I tried to view an online video, such as full length episodes on the TV network websites. I upgraded Adobe Flash to the latest version (version 9.0.124.0) and then repaired permissions and this took care of the problem. (Before I posted this I double checked the fix by going to the CBS and NBC web sites and watching 5 minutes of CSI:NY and Chuck and both played fine with nary a hiccup.)

  • Flash has suddenly stopped working with Safari and Firefox.

    I have a Wordpress blog. Suddenly, Flash has stopped working on Safari and Firefox in relation to my Wordpress module. But everything works fine from my PC laptop and other MACs owned by friends, etc. It is only on my iMac that Flash has stopped working. Any ideas?

    Please read this post then provide some details.  What printer model? What operating system? Do you have a 32 bit or 64 bit version?

  • Command + R (Refresh) not working in Safari and Firefox need Help!

    I been having trouble with Command + R (Refresh) in Safari and Firefox for a while, I used to have a MBP 2006 intel 2.4 running Leopard when the problem started,but since I was planning to change to a new computer I didn't pay much attention.
    Recently I got a MBP w/ Retina and migrated the info from my old Mac to the new one, and it seem like the Command + R problem to refresh in Safari and Firefox has been brought with the migration.
    Another pointer is that I have my mac setup in Spanish although it was setup in English before. This does not seem to be the problem.
    Any Ideas on how can I solve this?
    Than in advance.

    Recently Safari started slowing and presenting the infamous spinning wheel of death whenever page has anything flash in it. Since many pages have ads coming in on flash many pages are effected. I almost thought that I had a virus on machine, being a PC guy for 20 plus year prior you can get, pun intended, flashbacks of deadly blue screen etc. Was happening on both my machines readily apparent on homepage msnbc and the like. I cleared caches etc etc infinitum thought I was back on Windows for a minute. I know from listening to various Mac tech shows on twit.tv that Apple apparently is not fond of flash programming as evidenced that flash not on Itouch or Ipad. But what, trying to kil it on regular machines?
    When I first came to apple a couple years ago I was using Google Chrome browser on MSFT macines and loved it but atthe time Chrom did not make Mac version. I used Safari and was happy enough UNTIL LATELY with it not to bother with other browsers. NO MORE, so went hunting and happily found that Chrome for Mac available. AMAZINGLY no problems so far msnbc loads, without exaggeration, TEN times faster than on safari, no spiining wheels of death EVERYTHING faster like someone gave my Mac's a B12 shot and restored them to how they used to be. Easily transferred all favorites over simple import.
    So far only down side I have found was that bank statement pdf downloads and the like that Safari had bottom screen popup to one click download not on Chrome and print to pdf doesn't seem to do it right so far but I amstill playing. So when I do bank statements I fire up Sarari and suffer the speed.
    There is no reason for this APPLE!!! If you are not going to have Safari be the best browser out there for a mac then you should dump it and recommend sometghign else. Please don;t be like MSFT and Internet Explorer junk!

  • Safari and Firefox not loading images

    Recently I worked on somebody's MacBook Pro computer (a few months old but software is kept up to date) but I couldn't figure out why Safari and Firefox often would not show images. This person also has a desktop PC computer with the same problem in Internet Explorer. The mac laptop is connected to the internet via wireless and the desktop is wired to a Netgear router. The router is connected to a Motorolla Surfboard 5100 cable modem. The problem started about on the 16th of March. When I tried to open a page in Safari often half of the pictures did not show. In Firefox when I clicked the broken picture icon and selected 'show picture' then it will load. Also, in both browers, clicking refresh will usually, but not always, reload everything correctly. Clicking refresh does the same on the PC in Internet Explorer.
    Safari showed on the status bar there were errors on the page so I opened the Activity window. It said 'failed to connect' or something like that (I don't have the computer in front of me) for the images that did not load. Oddly, not all the images from the same site fail to load. Some will load but others won't. This happened with most sites and it appears to be random.
    I opened a terminal window and typed netstat. With no browser running there were still several connections. I'm not sure if that matters on a Mac in OS X. On a windows computer if there are several connections and no programs are open then there may be a problem with malware.
    It is possible the problem with images not loading has nothing to do with the Mac or Safari since we are having the same problem with the PC. The view images option in all 3 browsers is checked. I tried taking the router out and connecting only the PC to the cable modem. I tried unplugging and replugging all the ethernet cables. The owner of the computers spent a few hours on the phone with her internet provider. In the end they couldn't find what was causing the problem and tech support told her the internet was slow sometimes. We have the same internet provider and I'm having no problems with images on the same sites I viewed on her computer.
    Any ideas?

    Before somebody asks- yes, I tried clearing the cache
