About:blank appears on each web page change slowing laptop

each web page, when opening, displays "about:blank" for a few seconds, then proceeds. Entire Firefox loading and page changes are slower.

You can look at the network.protocol-handler.external.mailto and other mailto prefs on the about:config page. 
You can open about: pages via the location bar like you open a website.
Filter: mailto
If network.protocol-handler.external.mailto prefs are user set (bold) then right-click and Reset them to the default value. 
You can also try to change the network.protocol-handler.warn-external.mailto pref to true.
To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website. 
If you see a warning then you can confirm that you want to access that page. 
*Use the Filter bar at to top of the about:config page to locate a preference more easily.
*Preferences that have been modified show as bold(user set).
*Preferences can be reset to the default or changed via the right-click context menu.

Is this in safari?
try going into settings, safari and clear history. You may also want to clear cookies (means you will need to sign back into sites)
It's possible that that page is a popup ad of some sort that can't run, for example a flash based ad. You may have picked the cookie up browsing the internet and now that it's in there the only way to get rid of it is to clear your history and cookies.

A blinking cursor appears on every web pages.

It's a blinking cursor that appears on every web pages in different sizes when I click anywhere on the web pages.
Look at following pictures please:

I believe that it's been originated and are spread from Google's Keyboard Navigation feature. As you may know, if you are using Google's Instant Search feature, you can use the keyboard to navigate Google's search result page.
I did turn off the Instant Search to disable Keyboard Navigation, but the blinking cursor is still blinking on every Google and non-Google web pages.
Next as a standard troubleshooting procedures for strange behavior I cleared cache and cookies , but it didn't help.
I was using Firefox 3.6, so I uninstalled 3.6 (kept my personal information) and installed the latest version (3.6.13), but it didn't fix the problem.
I don't see that cursor in IE. How can I get rid of it?
Thanks in advance.

In Firefox 3.6 and later versions you can disable the F7 shortcut that toggles caret browsing by setting the pref accessibility.browsewithcaret_shortcut.enabled to false if you do not want to use that feature.

Javascript not working in Firefox 32.0 - about:config says enabled - but web pages say different

For example maps not loading on hotel pages. Various other errors appear now on web pages saying ' You must have JavaScript enabled'. I'm not a computer person, but I can see from about:config says its enabled -
javascript.enabled;true
Any other suggestions???

You can open the Web Console (Firefox/Tools > Web Developer).
Check on the Network tab if any content is blocked and has a file size 0 (zero).
*https://developer.mozilla.org/Tools/Web_Console
You can try these steps in case of issues with web pages:
You can reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.
*Hold down the Shift key and left-click the Reload button
*Press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
*Press "Command + Shift + R" (Mac)
Clear the cache and remove cookies only from websites that cause problems.
"Clear the Cache":
*Firefox > Preferences > Advanced > Network > Cached Web Content: "Clear Now"
"Remove Cookies" from sites causing problems:
*Firefox > Preferences > Privacy > "Use custom settings for history" > Cookies: "Show Cookies"
Start Firefox in [[Safe Mode|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
*Do NOT click the Reset button on the Safe Mode start window

Have each web page display at full page width automatically

How can I set Firefox to automatically display each web page that I open at full page width. Microsoft IE9 does this for me and it is very helpful.
I have to adjust each web page to full width every time, since Firefox does NOT remember the full page display even if I come back to a previous web page which I already adjusted before.

Great news, thanks!
Don't know what a mac newbie like me would do without this forum. Thanks a million.
Great to hear, there are plenty of great helpers here, so feel fee to post a new topic whenever you wish.
By the way, is this technique covered anywhere in Mac help?
Yep, click on the Finder in the Dock, click Help up in the Menubar>Mac help, type windows into the search at top right, hit ENTER, should get a list, 4th down here.
Seems Windows7 is a big improvement over Vista, but still not as good as XP, certainly more of a pain than XP.

It opened fine for me, sometimes it takes the Apple servers a while to respond so may be at that end the problem lies not with your internet connection. That is why people suggest other hosts for commercial sites. I like your site - very good layout.

Safari 8.0 no longer appears to cache Web pages.

Since upgrading to Yosemite, Safari no longer appears to cache anything. Pages reload each and every time a page change is made. It affects both backwards or forwards changes and does not matter if I use the arrow buttons in Safari or swipe across the MagicPad.
As suggested on various other help sites;
I have removed all extensions from Safari
I have put Safari into single process mode
I temporarily removed the Cache folder from the Library so that Safari created a new one when it was restarted
None of the above had any effect, the issue remains.
Is anyone else experiencing this issue or knows how to fix it?

Hi Paul and Welcome to Apple Discussions
Do you have a similar fix for slow Safari 4.0.3 on an iBook G4 running OS X.4.11?
Go to the System Preferences>Network panel
-Location - set up a personal location by clicking on the location drop down menu and selecting "add a location". Use a name familiar to you. Once established, select "apply".
-Next, click on the "Show" drop down menu and select Network Port Configurations. Depending on whether you use Ethernet or Airport (wireless) for your setup: Only Ethernet or Airport ought to be checked. Move it to the top of the list (you can drag it). Select "apply". Everything else ought to be unchecked unless you use a Bluetooth device.
-Back to the "Show" menu, select either "Ethernet" or "Airport" (whichever applies to you). Click on the TCP panel. There, enter (copy/paste on separate lines) 208.67.222.222 and 208.67.220.220 in the DNS servers box - these are Opensource DNS codes.
When done, select OK, then "apply"
Last step: In the Finder, go to your Utilities folder and select "Terminal". Once the screen is open copy/paste lookupd -flushcache and press return. This clears out the DNS cache. Once done, quit Terminal.
Restart Safari
In Safari Menu>Reset Safari. Select "empty the cache", then reset.
Try a URL

Many images do not appear on numerous web pages. How can I fix this? I have graphics enabled.

For quite some time many images just do not appear on web pages. I have taken a screen shot of a page to show what the problem is but can find nowhere to upload it so you can see for yourselves. Now what do I do?

If images are missing then check that you aren't blocking images from some domains.
*Press the F10 key or tap the Alt key to bring up the hidden "Menu Bar" temporarily.
*Check the permissions for the domain in the currently selected tab in "Tools > Page Info > Permissions"
*Check "Tools > Page Info > Media" for blocked images
*Select the first image link and use the cursor Down key to scroll through the list.
*If an image in the list is grayed and "Block Images from..." has a check-mark then remove this check-mark to unblock images from this domain.
Make sure that you do not block (third-party) images, the permissions.default.image pref on the about:config page should be 1.
Make sure that you haven't enabled a High Contrast theme in the Windows/Mac Accessibility settings.
Make sure that you allow pages to choose their own colors.
*Tools > Options > Content : Fonts & Colors > Colors : [X] "Allow pages to choose their own colors, instead of my selections above"
Note that these settings affect background images.

There are extensions like Adblock Plus (Firefox/Tools > Add-ons > Extensions) and security software (firewall, anti-virus) that can block images and other content.

Someone said to add the title on each web page on the main text box. Which is that?

I read in the discussion items that you should not bother with meta tags but just wirte the title in your main text box on each page with the word image in the beginning. Where in the main text box? The first one on the page? That has my web page title. Help. Judy

iWeb uses the textbox in the Header layer of an iWeb page as the title in the browserwindow.
Do not remove the original textbox, as you cannot replace it other than by selecting another theme and then change it back to the original theme again. Ruining the layout in the process.
If the textbox in the Header is missing, iWeb uses a textbox down the page in the Content layer. If that textbox is also missing, it uses another textbox. If that fails it uses the pagename in the Sidebar.
Sometimes you may want a different text in the titlebar and not display it on the page itself. Or not display it at all.
So use that textbox in the Header layer. Type your text. Then select the textbox. In the Inspector choose T, click a color to open the color palette and drag the opacity slider to 0 (zero).
Do Command-T to open the font palette and make the font smaller. (Or do Command--(minus)) Also use a font that doesn't change to an image. Arial is a good font. Perhaps do it first before making the text invisble.
Resize the textbox. You may want to change the height of the Header layer.
Do Command-Shift-B to move the textbox to the back, possibly behind other objects.
Next add a optional second textbox to the Header layer and use that one to display text on the page.
If you want to move the textbox to the front again to make changes, but can't remember the location on the page, drag the area with the mouse to select the objects.
Deselect objects you do not want to move forward by Command-dragging the mouse over these objects.
Next do Command-Shift-F to move the textbox to the front. Repeat the steps in reverse order to make the text visible.
Practice.

When I click on the firefox icon, "about home" or "about blank" appears in the address bar.

about blank or about home is appearing in my address bar. How can I get it to read mozilla?

Yes, it's normal behavior, but there is any add-on or any possibility that address bar would be empty when you click on home page button?
It would be more comfortable if you didn't have to clear address bar.
Thanks for help.

Strange icon appears on my web pages

I have a web site and for a long time now this icon has been appearing in my editor and now it sometimes appears on my live web page this is the icon 
I have disabled all my plugins and add ons have disabled F7 someone had suggested the charset Currently using charset=iso-8859-1) was set incorrectly but my webmaster says that is not the cause,this is only happening in FF in IE it is ok, most of my pages are not affected yet some have 20 to 30 of these icons spread around the page,anyone with some fresh ideas would be appreciated.

I have cleared all current icons,mostly they occur in the back end of my site in my editor page,only recently they have been appearing on my published site. So wouldn't be able to give you access,was hoping someone may have experienced the same problem.
Thanks for the response

Adding web page in Adobe Muse that can be accessed from each web page

I have a disclaimer link at the footer of each of my web pages, I want it ot be accessed from each page. Where in Adobe Muse do I insert this page?

I'm new to Muse so two more questions for you all--
1. How do I add a drop down menu feature to my navigation menu to show the sub navigation?
2. How do I insert a Contact Form so that people can fill it out and send to us via email through our website?
Thanks!

Question about using PowerShell to detect web page availability and then perform alternate action.

I have a specific Windows 7 machine that needs to always display a specific Intranet page. (it shows an internal status page in kiosk mode).
If this machine every loses connectivity to the web server, unfortunately, the browser shows the typical "web page could not be retrieved" error message and it never recovers. I need to manually reload the page when the connection is restored.
I'm thinking if it would be possible to write a PowerShell script that checks the connectivity/availability of the Intranet page and if it detects an error, it would launch a browser that points to a local file html file which would say something more professional
and graceful like "site temporarily down for maintenance." Also, if the PowerShell script could run on a regular interval, when the Intranet page becomes available again, it would close the browser that is showing the maintenance page and start
showing the page with the original Intranet site.
For the Intranet site checking, I was looking at the invoke-webrequest: as the mechanism.
Any guidance would be appreciated as I am new to PowerShell.

With these lines you get the static content of the web page:
$page = new-object net.webclient
$page.UseDefaultCredentials = $True
$Page.DownloadString(“http://www.intranet.local.com/”)
You could first check whether the web server is pingable, then use the lines above to see whether there is a HTML response.
If the web server doesnt respond you could kill the browser process and then open a HTML page stored locally on the Win 7 client:
Invoke-Item .\ErrorPage.html
If the web server responds, kill the browser and restart it showing the Intranet page.
All this run from a scheduled task.

Web pages very slow to load if at all

I just bought my first Mac about 9 months ago...and was loving it until 7-10 days ago the web access has slowed to a crawl, and sometimes not at all. I also seem to recall it was about the time I updated some software.
I have tried several of the suggestions on these forums...adding DNS numbers, reversing DNS numbers....etc...nothing has worked thus far.
It also seems to have affected Firefox... is that possible?
Many times I cannot even access the web at all...I had to try about 6-7 times just to get to this Apple website.
I am wide open to any suggestions. Please note...I am only somewhat savvy regarding operating systems...so be gentle!!

HI,
Go to ~/Library/Caches/com.apple.Safari and move the "cache.db" file to the Trash.
If deleting the cache.db file doesn't help, go here for trouble shooting 3rd party plugins or input managers which might be causing the problem. Safari: Add-ons may cause Safari to unexpectedly quit or have performance issues
If it's not third party add-ons, troubleshoot the Safari .plist file.
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 and see if that makes a difference. If not, move the .plist file back to the Preferences folder. If Safari functions as it should, move that .plist file to the Trash.
 Web pages include a small icon or 'favicon' which is visible in the address bar and next to bookmarks. These icons take up disk space and slow Safari down. It is possible to erase the icons from your computer and start fresh. *To delete Safari's icon using the Finder, open your user folder, navigate to ~/Library/Safari/ and move this file "webpageIcons.db to the Trash.*
And if you didn't repair disk permissions after the update, it would be beneficial to do so.
Launch Disk Utility. (Applications/Utilities) Select MacintoshHD in the panel on the left, select the FirstAid tab. Click: Repair Disk Permissions. When it's finished from the Menu Bar, Quit Disk Utility and restart your Mac. If you see a long list of "messages" in the permissions window, it's ok. That can be ignored. As long as you see, "Permissions Repair Complete" when it's finished... you're done. Quit Disk Utility and restart your Mac.
