My iMac won't load certain websites

Soon after replacing Comcast router, my iMac V 10.6.8 would not load most sites; or they would take 10-15 minutes to load with virtually no subsequent functionality. eBay is one of the only sites to load and respond. Apple, comcast, google and most others will not load. I have reset Safari, and also permissions. I have backed up both with iCloud and external drive at this point so ready to try anything. Thanks

Go to System Preferences > Network. Select your network connection (Wi-Fi, unless you aren't using a wireless network) then the Advanced... button, then the TCP/IP tab.
What, if any, addresses are shown under DNS Servers? Some may be "greyed out".
Next: read OS X: How to reset the DNS cache
Next: Check your Mac's Hosts database.
In Terminal, copy and paste the following
cat /etc/hosts
It should only be a few lines of text completely identical to the following, and nothing other than the following, unless you have valid reasons for having changed it:
# Host Database
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
fe80::1%lo0 localhost

Firefox won't load certain websites.

Firefix won't load some certain websites. I even have to use google chrome now, to ask advice. I did all the things said in the help page but it only seemed to turn internet connection slower! It seems that FF is having problems with save websisites and sites that redirect somewhere. like www.zone.ee, ois.ut.ee and some other ones, i can't access my gmail either. So I really need to solve this problem asap.

Do a malware check with a few malware scan programs. 
You need to use all programs because each detects different malware. 
Make sure that you update each program to get the latest version of the database.

Safari won't load certain websites but Chrome does :/

Hello!
I am running OSX 10.10 and safari ver Version 8.0 (10600.1.25). I had the Yosemite beta before this current installation and Mavericks before that.
When I try opening certain websites with Safari they will not load. They will get stuck in the "loading" screen (the blue bar under the omnibar will start going from the left to the right) but the page simply wont load. When I try to access the same website with Chrome it loads instantly. Is there any way to reinstall Safari from scratch to see if that will solve the issue?
Thanks!

MIght be a plugin ...
From your Safari menu bar top of your screen click Safari > Preferences then select the Security tab.
Deselect: Enable plug ins. Quit then relaunch Safari to test.
If that made a difference then you need to troubleshoot third party add ons > Safari: Unsupported third-party add-ons may cause Safari to unexpectedly quit or have performance issues
And try deleting the cache associated with Safari. (Not the same as deleting the cache from the Safari menu bar.
Open the Finder. From the Finder menu bar click Go > Go to Folder
Type this exactly as you see it here:
~/LIbrary/Caches/com.apple.Safari
Clck Go
Move the Cache.db (or ApplicationCaches.db) file from the com.apple.Safari folder to the Trash.
Quit then relaunch Safari to test.
And several of the sites you mentioned require the Flash plugin. Try uninstalling the currently installed Flash plugin, then reinstall new > Troubleshoot Flash Player | Mac OS
Make sure there's enough free space on the starutp disk.
Right or control click the MacintoshHD icon in your Desktop. Click Get Info.

Safari won't load certain websites

When I use Safari 5.0.6 on my MacBook running Mac OS X 10.5.8, various websites will not load. Some will load fine, like the home page of New York Times. However, if I select an article, it won't load. If I try to load google search, it may take several minutes to come up. my.yahoo page will NOT load forever and ever. When I state that it 'doesn't load' I mean that you'll see the address in the address bar and halfway thru that will be a blue progress bar. It just sits there like that and doesn't ever finish loading. If I try the same pages on Firefox, I have no problems at all. I have run the ClamXAV to make sure it's not a virus and it found nothing. I'm not sure what's going on. I have tried resetting Safari and clearing the cache and whatnot, but it made no difference. I tried allowing pop-ups. No change. This has been going on awhile and it's just irritating. Any suggestions?

Safari and Firefox Won't Load Certain Websites

Starting just today, Safari nor Firefox will go to my university's website. www.weber.edu. I've tried everything I can think of. I reset both browers. Restarted the computer. I thought maybe it was my router/network, but my windows laptop had no problems loading the website. I have an '07 iMac with the latest version of snow leopard, Safari, and Firefox. This just happened out of the blue. It worked just fine yesterday.
Thanks for any help that can be offered.
Jonathan

Please launch the Terminal application, copy or drag -- do not type -- the text below into the window, and press return. Post any lines of output that appear below what you entered (there may be none.) If nothing happens within 30 seconds, consider that to be no output. You can then quit Terminal.
curl -I http://www.weber.edu

Firefox won't load certain websites, so I need to install an earlier version.

I've used the public forums on those websites to get support, and most people say that installing Firefox 14.01 will fix the problem. Where can I go to install Firefox 14.01? I'd prefer installing it here, on Mozilla.org, rather than going to a less reliable site.

Yes you may download Firefox 14 from an official Mozilla Firefox site see
*[[Install an older version of Firefox]] that does warn you about security risks and not to do it, but then includes a download link.
There will almost certainly be better fixes or workarounds to almost any problem than using an insecure Firefox 14. (Bar changes to how some web pages look, I can not immediately think of anything that gets fixed by downgrading to firefox 14, other than the usual problems with incompatible extensions that take a while before they are updated )
Personally I would suggest for a knowledgeable user a better solution is to go to the other extreme and run Firefox Beta as standard, and only downgrade to the secure Release if a problem occurs. (That philosophy does not work if you rely on security related binaries - but the majority of users are on legit Windows systems and can make use free MS software anyway.)
What problems are you having ?

TX won't load certain websites

Two days ago, my TX stopped loading google, gmail and other websites but still does load aim mail and some other sites.
The error message that comes up is "The page you requested cannot be displayed. The web site you are trying to access may be temporarily unavailable or the URL you entered cannot be reolved. Please check that you correctly entered the URL or try again later." The URL are all bookmarked and haven't changed.
I've even tried the hard reset to no avail.
Help!

Problem loading certain websites

For the past year or so, my iMac has (running Mac OS X 10.5.8) has been giving me trouble when it comes to loading certain websites. The reason why I think it's my computer as opposed to my browser or my internet connection is because these websites will load on other computers connected to the wireless network in my home, and because the problem persists with any browser I attempt to use - I've tried Google Chrome, Firefox and Safari and none of them load these websites. (Also, they load fine when I'm on the internet via my iPod touch.)
The websites in question include about.com, ehow.com, and any website with a .me extension. There are others, but those are the three that come to mind at the moment. When I try to go on about.com for example, the page simply does not load. There's not even an attempt to load the page. It's very frustrating because I see no reason why these websites shouldn't work.
I have tried clearing the caches, history and preferences for all browsers, as well as logging in as a different user on my computer and seeing if these websites worked - they didn't work, even as a different user. I was told it could be a problem with the .plist files, so I dragged all of them into the trash and tried loading these webpages, but it still didn't work. Does anyone know what else it could be? Also, I apologize if my description of the problem was unclear.

Some other things you can try:
1. Run Software Update (in the Apple Menu) and make sure you have all available Apple updates for OS X.
2. Go to Adobe.com and make sure you have the latest versions of Shockwave and Flash for your computer installed.
3. Go to System Preferences > Parental Controls and see if any restrictions have been established.
4. Go to System Preferences > Accounts and set up a new user account. Try using your browsers from this account. If they work, there is a problem with your "old" account. Next steps will depend on how much time and effort you're willing to devote to troubleshooting.
5. Power cycle your router and computer.
6. Go to System Preferences > Network. Highlight your router (assuming you're using a wireless connection) and select the "TCP/IP" panel. Click on the "Renew DHCP Lease" button.

I'm unable to load certain websites across all browsers on a MacBook Pro

Suddenly I'm unable to load certain websites (sundancechannel.fr, sundancechannel.tw, etc.) across all browsers—Safari, Firefox, Chrome—on my new MacBook Pro. Other computers on the same wifi can access those same sites fine.
I either get a won't connect to server message or a blank page.
Any idea what's going on?
I've thus far tried restarting the connection, clearing my cache, restarting the computer, deleting my history, and even getting in touch with the site owners.

Cambrey,
that HTML content shows that there’s no content at that Web site — it will only show the heading “301 Moved Permanently” and the single line “nginx/1.2.6”. I suspect that they might have wanted to include a redirection directive in that document, but for some reason, they didn’t. Your browsers are behaving as they ought to do with this Web site.
Have you considered trying www.sundancechannel.fr in your browsers instead of sundancechannel.fr?

My MacBook Pro won't load any websites on Safari (except this site, Facebook and Google), Opera, or Mozilla Firefox. I already did the "Reset Safari", restarted the computer half a dozen times, and I can't find this alleged "caches.db" file to delete.

My MacBook Pro won't load any websites on Safari (except this site, Facebook and Google). Opera and Mozilla Firefox won't load any sites whatsoever. I already did the "Reset Safari" several times, restarted the computer half a dozen times, and I can't find this alleged "caches.db" file to delete. I virus scanned the computer with Sophos, Avast, and iAntiVirus and it looks clean.

Is iAntiVirus the best virus protection to use for a MacBook?
The best anti-virus protection is your own common sense, and what you already bought and paid for with your Mac. Third party products such as "iAntiVirus" convey no additional benefit, and as you already determined are very capable of causing trouble.
OS X already includes everything it needs to protect itself from viruses and malware. Keep it that way with software updates from Apple.
A much better question is "how should I protect my Mac":
Never install any product that claims to "speed up", "clean up", "optimize", or "accelerate" your Mac. Without exception, they will do the opposite.
Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources. Illegally obtained software is almost certain to contain malware.
Don’t supply your password in response to a popup window requesting it, unless you know what it is and the reason your credentials are required.
Don’t open email attachments from email addresses that you do not recognize, or click links contained in an email:
Most of these are scams that direct you to fraudulent sites that attempt to convince you to disclose personal information.
Such "phishing" attempts are the 21st century equivalent of a social exploit that has existed since the dawn of civilization. Don’t fall for it.
Apple will never ask you to reveal personal information in an email. If you receive an unexpected email from Apple saying your account will be closed unless you take immediate action, just ignore it. If your iTunes or App Store account becomes disabled for valid reasons, you will know when you try to buy something or log in to this support site, and are unable to.
Don’t install browser extensions unless you understand their purpose. Go to the Safari menu > Preferences > Extensions. If you see any extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone.
Don’t install Java unless you are certain that you need it:
Java, a non-Apple product, is a potential vector for malware. If you are required to use Java, be mindful of that possibility.
Java can be disabled in System Preferences.
Despite its name JavaScript is unrelated to Java. No malware can infect your Mac through JavaScript. It’s OK to leave it enabled.
Block browser popups: Safari menu > Preferences > Security > and check "Block popup windows":
Popup windows are useful and required for some websites, but popups have devolved to become a common means to deliver targeted advertising that you probably do not want.
Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
If you ever see a popup indicating it detected registry errors, that your Mac is infected with some ick, or that you won some prize, it is 100% fraudulent. Ignore it.
Ignore hyperventilating popular media outlets that thrive by promoting fear and discord with entertainment products arrogantly presented as "news". Learn what real threats actually exist and how to arm yourself against them:
The most serious threat to your data security is phishing. To date, most of these attempts have been pathetic and are easily recognized, but that is likely to change in the future as criminals become more clever.
OS X viruses do not exist, but intentionally malicious or poorly written code, created by either nefarious or inept individuals, is nothing new.
Never install something without first knowing what it is, what it does, how it works, and how to get rid of it when you don’t want it any more.
If you elect to use "anti-virus" software, familiarize yourself with its limitations and potential to cause adverse effects, and apply the principle immediately preceding this one.
Most such utilities will only slow down and destabilize your Mac while they look for viruses that do not exist, conveying no benefit whatsoever - other than to make you "feel good" about security, when you should actually be exercising sound judgment, derived from accurate knowledge, based on verifiable facts.
Do install updates from Apple as they become available. No one knows more about Macs and how to protect them than the company that builds them.
Summary: Use common sense and caution when you use your Mac, just like you would in any social context. There is no product, utility, or magic talisman that can protect you from all the evils of mankind.

IMac won't load some web pages

I just got wireless internet out on my farm and hooked up my fairly new IMac G5 to it. When I connect it directly to the antennae (not through a router) everything works great. When I hook it through a router ( I have used linksys wireless g and a netgear wgr613 v6) the Imac will only load certain web pages. e.g. It will load Apple.com, but won't play the Macworld keynote address. It won't load Ebay at all. It will load cnn.com and others just fine. When I bypass the router, everything loads and works. I have also taken the IMac to work and hooked up to our office ethernet through a router, multiple wireless access points, and hubs, and the IMac works great all of the time. I tried the linksys first and it works for a little while and then fizzles away to nothing working. I then upgraded firmware and it worked a little while longer before dying. The netgear works all of the time for some, but not everything. When I hookup my Windows XP notebook, it works all of the time on either router. I have tried both routers either wireless, or wired, with the same results. Thanks....

Yes, that did it. I put in the two DNS numbers for my ISP and that solved the problem. Still don't understand why that caused it, but yet worked sometimes. Oh well.....Thank you

Thanks for that information!
I'm sure I will be calling AppleCare, but the problem is, they charge for the phone calls don't they? Because I don't have money to be spending to be on the phone with a support service.
In other things, it seemed like the only time my MacBook was working was when I had Snow Leopard without the 10.6.8 update download that was supposed to be done to prepare for OS X Lion.
When I look at the information of my HD it says that I have 10.6.8 but that was the install that it claimed to have failed and caused me to restart resulting in all of the repeated problems.
Also, because my computer is currently down, and I've lost all files how would that effect the use of my iPhone? Because if it doesn't get fixed by the time OS 5 is released, how would I be able to upgrade?!

Firefox cannot load certain websites and I've tried all suggested options to fix the problem.

I cannot load certain websites (my bank, some public/civic offices, etc.) on Firefox or Internet Explorer (I usually use Firefox) and have tried all the suggested options in Firefox Help to remedy this problem: clearing cache and cookies, making sure no proxy is selected, allowing cookies). How do I fix this? I use a broadband internet connection that is shared.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
 To Enable SafeMode 
*You can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
*''Once you get the pop-up, just select "'Start in Safe Mode"''
If it works in Safe Mode and in normal mode with all extensions (Tools > Add-ons > Extensions) disabled then try to find which extension is causing it by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: "Firefox > Quit Firefox"; Linux: "Firefox/File > Quit")

My computer will not load certain websites

Hi,
Both Safari and Firefox will not load certain websites consistantly (Twitter is one of them). I check on my wife's computer and they can load on her computer no problem. It shows the "Problem Loading Page" message. I've cleared history, cache, everything that I can think of. Any ideas?
Thanks,
Richard

Hello,
In a browser's URL bar, put this & hit enter, does that get you to Apple?

Need to click in address bar to load certain websites

Firefox never finishes loading certain websites. However, clicking on the site address in the address bar then immediately loads them. This also happens with all add-ons disabled. What gives?

Create a new profile as a test to check if your current profile is causing the problems.
See "Basic Troubleshooting: Make a new profile":
*https://support.mozilla.com/kb/Basic+Troubleshooting#w_8-make-a-new-profile
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.
