I keep getting this alert: The URL is not valid and cannot be loaded. What does this mean and what do I need to solve this?

Everytime I try to open an email or any other site, I keep getting the above message and it keeps kicking me out of system.

Do you have that problem when running in the Firefox SafeMode?

Why do I get error message "The URL is not valid and cannot be loaded" when everything looks OK?

This message pops up while using programs like yahoo mail. I delete it and everything continues as normal.

Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
* Don't make any changes on the Safe mode start window.
See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
* Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
* Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

My Browser cannot load web pages. I get The URL is not valid and cannot be loaded"

I can no longer use Firefox. EVERY PAGE I attempt to load produces the following message alert: "The URL is not valid and cannot be loaded"
I have already cleared everything in my browser, rebooted my computer and absolutely nothing works. This just started happening constantly today.

Do other about: pages work properly?

When we connect to the internet or visit a new web page, a new tab opens and an alert pops up as follows: "The URL is not valid and cannot be loaded"

When we start the internet or navigate to a new page, a new tab opens with the following alert: "The URL is not valid and cannot be loaded." We "x" out of it, but a new tab, with the same alert appears. The problem occurs again when we try to navigate to another web page. A real nuisance. We've scanned the computer but found nothing but Adware cookies.

The URL is not valid and cannot be loaded. This statement comes up on almost any attempt to log into or click a link to anything at least on 2 tries, then the site comes up. what's up with this?

firefox v 3.6.13 is what I use. If I select something from "read Later" or a link from the home page to another site, I get that message - The URL is not valid and cannot be loaded. in a box that pops us a couple of times, then the site I want.

The URL is not valid and cannot be loaded

seems like maybe firefox mishandles untrusted certificates?
It gives error: Alert The URL is not valid and cannot be loaded.
example:
https://notes.corp.cat.com/
other browsers can load this URL just fine. When I visit it in Firefox, I get the error in a simple little message box with a yellow triangle exclamation point, titled "Alert".
ALSO.... when I click the "Home" button in firefox, I get the error, and the home page does not load. Currently the home page is set to "Mozilla Firefox Start Page."
changing the home page to: http://www.google.com/ allows the home page button to work normally.
restoring the home page to default brings the error behavior back when clicking the home button.
changing the home page to: https://notes.corp.cat.com/ produces the same error, just like when I manually type in an https URL with a funky security certificate.
This problem only seems to happen on secure URLs with untrusted certificates, i.e. sites that are too cheap to pay to have their certificate registered with one of the certificate vendors or however the hell that works, so as a result every time you visit their web site, your browser starts to whine that it might be a forgery or whatever.
It used to be in Firefox that I could load these pages and just specify that I want to trust the site anyway. Now firefox gives this error that doesn't allow the user to know what is really going on or what the reason for the error is. It is as if the developers decided that users are too stupid to decide if they really want to visit the site or not, so as a result Firefox is just refusing to visit any web sites where the authenticity of the certificate can't be verified? Hey, it's not a bad idea, to be honest. :-) But it's kind of annoying, because here I am, sort of smart enough to know what I'm doing, but I don't have the choice in the matter...
I restarted with all add-ons disabled and that didn't help. I don't have much installled in the way of add-ons anyway. All I have is JAVA quick starter 1.0, and Adobe Acrobat, Java development toolkit, Java platform SE, Microsoft DRM, and Windows Media Player Plug-in Dynamic Link Library. Not even Flash. All the above is disabled now that I rebooted with add-ons disabled, and I still have the issue.
thanks for any help you can provide.

A Linux version fo Mozilla Firefox 6 Start Page states "The URL is not valid and cannot be loaded." - Why?

Hi, My Linux Mint (a Debian/Ubuntu flavor) when first seen, the Mozilla Firefox 6 Start Page was great. However, when moving away to other sites and then clicking home the response was Alert - "The URL is not valid and cannot be loaded." Having trying everything (apart from using a large club!) I am lost. Any suggestions team? Mark

I keep getting the alert window that says, "the url is not valid and cannot be loaded"

My computer is "online" but whenever I try to get on a website, the "Alert" box pops up in the middle of my screen saying, "the URL is not valid and cannot be loaded". This is only happening on Mozilla Firefox, I am able to use Internet Explorer without any problems. I do prefer to use Mozilla Firefox as my browser though.

My internet is on and I keep getting an alert window popping up saying the URL is not valid and can not be loaded?

I don't know what more details I can give you except for what I indicated. I am online and a window will pop up indicating the URL is not valid and can not be loaded. Make it stop! That's all! Furthermore you should not limit people on the length of their question. How can they explain it ?

Thats the annoying part! I have enough space and I'm putting things on a external hard drive and I keep deleting it off the computer.

After updating to firefox 9 when i click on the "home" icon i get an alert that the url is not valid and can't be loaded. Why?

my computer updated to firefox 9. update was ok, but now when i click on the "home" icon, i get an alert that the url is not valid and cannot be loaded. everything is good to go as far as web surfing and so forth, but i want the firefox start page as my home page. also the private browsing option won't work because of the invalid url.

Hi ozzie427,
What URL do you have bookmarked as your home page? You might want to look at the Knowledge Base article [[How to set the home page]]. There are steps in there to restore the home page to default. I would try that first to see if it clears up any strangeness. If that works, you can set the home page to anything you like.
Hopefully this helps!

When I open firefox I get this message; The address isn't valid The URL is not valid and cannot be loaded.

I get this message whenever I open firefox or a new tab. Anything I had tabbed to the top has gone, and the original homepage which shows all my recent visits is invalid. The full message is:
The address isn't valid
The URL is not valid and cannot be loaded.
Web addresses are usually written like http://www.example.com/
Make sure that you're using forward slashes (i.e. /).
Try Again.
Help mee!!!

Hi fredmcd-hotmail
It's not that I'm typing anything in wrong, it's when I first open Firefox or a new tab. Instead of displaying the firefox page showing my recently viewed websites it's just an invalid URL. Why would I be blocked from this page?
Thanks

Why do I keep getting an error message that reads "The URL is not valid and cannot be loaded."

Whenever I click on a link that opens a new tab using "about:tab", an error pops up. The error box is titled "Alert" and the message reads "The URL is not valid and cannot be loaded."
However, once I click OK, the page loads just fine. At first, I thought it might be one of my add-ons (Iuse a bunch), but it still occurs after restarting in Safe Mode. Any thoughts?
I can even create the problem without clicking on a link inside a page if I simply type about:tab in the address bar.
I am using Firefox 12.0

Wow! I actually solved this on my own. I didn't find any thread that helped, but after reading a few, I figured poking around in about.config would help... and it did!
Here is how I solved the problem:
# Typed '''about:config''' in address bar.
# When I got to the warning about voiding the warranty, clicked '''I'll be careful, I promise!'''
# I found the setting entitled '''browser.newtabl.url''' (use the '''Search:''' box).
# I double-clicked on the entry entitled '''browser.newtabl.url''' and deleted the info in the value portion.
# Clicked '''OK'''.
# Closed the tab.
# Restarted Firefox and problem was solved.

I am getting an Alert, that says, "The URL is not valid and cannot be loaded.

Can't think of anything else to say.

i get the same message, "The URL is not valid and cannot be loaded.".
i've narrowed it down a bit more.
i've got a freshly installed firefox US 9.0.1 on a freshly installed windows xp pro sp3 US (fully patched). a freshly installed separate firefox 3 install is on this machine too, but that does not seem relevant.
the problem only occurs when i load https-urls with invalid certificates (eg self-signed) in the case that i use a firefox with a non-default profile.
so the "default" profile displays a "this page cannot be trusted" screen as expected, i can open the url. but in a different firefox instance/profile, when going to the same https url, i get the error popup. the firefox profile/instance is started like this: firefox.exe -P dev -no-remote.
i have reinstalled firefox 9 & 3 because of this issue. the problem stayed. i didn't remember whether i could load the https url with the default before the reinstall. perhaps i couldn't...

It's a really bad idea to post your iPhone's serial number and I've asked the Hosts to remove it.
Any one device can create only three iCloud accounts. As you have apparently already created three accounts (or if it's a used phone the previous owner did) you cannot create any more one it. This is tied to the hardware, not the account, and there is no way round it.
You can create a new iCloud account on another iOS device or on a Mac, and then you will be able to sign into that on your iPhone.
