When clicking on making a new tab it comes up with "The URL is not valid and cannot be loaded" how do i fix this

The URL is not valid and cannot be loaded keeps coming up whenever making a new tab. can not seem to fix have firefox 3.6.13

Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the 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]]
* [[Troubleshooting plugins]]
If it does work in Safe-mode then disable all 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")

Sometimes when firefox loads a web page the error message comes up stating The URL is not valid and cannot be loaded. And I know this is a valid web site. What gives?

This happens very often. When I open Mozilla sometimes I get an error stating that "The URL is not valid and cannot be loaded." When I click ok the site stops loading and the tab is titled untiled.

This can be a problem with DDE. 
See http://kb.mozillazine.org/Windows_error_opening_Internet_shortcut_or_local_HTML_file_-_Firefox

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.

When I click on the Home button, I get a message saying "The URL is not valid and cannot be loaded????????"

When I first turn on Firefox, I only get a blank "new tab". It does not go to the Firefox Home Page. When I click on the Home button in the top right, I get the message "The URL is not valid and cannot be loaded." How can I fix this so when I open Firefox it goes right to the Firefox Home Page (or a home page of my own choosing)??

[[How to set the home page]] has detailed instructions.
To get back to the default home page:
# At the top of the Firefox window, click on the Firefox button (Tools menu in Windows XP) and then click Options.
# Select the General panel.
# In the Startup box, click Restore to Default.
If this isn't "sticking", you may have malware or an extension that is preventing you from making the change.

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).

Delete a possible user.js file and numbered prefs-##.js files and rename (or delete) the prefs.js file to reset all prefs to the default value including prefs set via user.js and prefs that are no longer supported in the current Firefox release.

When I click on "Sign in to Sync" the page "about:accounts" shows error "The URL is not valid and cannot be loaded." How do I fix this so I can use Sync?

When I click on the three-bar icon (top right) and then on "Sign in to Sync" a new tab opens attempting to load "about:accounts" . . . the page that loads is an error . . . "Problem loading page" shows up on the tab and the page displays:
The address isn't valid

When I click or type in a valid link, I get the message "The URL is not valid and cannot be loaded." I have to reload/refresh the page one or more times until the same page loads.

This happens with small sites as well as major ones such as amazon.com. It happens frequently with many different websites both when typing in a URL or clicking on one from search results or other pages. If I am opening it in a new tab, the page is blank and the correct URL shows in the address bar even though it didn't load. When I get the message "The URL is not valid and cannot be loaded" I have to click okay and then click on the link again or click refresh. Sometimes it loads on the 2nd try; other times I have to refresh multiple times to get it to load.
Anyone know what is causing this or what will help?

I am getting this error message, " The URL is not valid and cannot be loaded" when I try to go to Firefox home. I have uninstalled add-ons, uninstaleed and reinstalled a fresh new firefox which did not help

I am getting the following error message, " The URL is not valid and cannot be loaded" when I try to go to firefox home. I uninstalled add-ons , uninstalled Firefox and then installed a fresh version. Still have the problem.
Thanks for the help

That issue can be caused by a corrupted or incomplete Visual C++ installation (multiple versions can be installed side-by-side; SxS) that is missing some runtime components (Redistributable Packages) that Firefox depends on (problem with an embedded manifest file that specifies a specific runtime version).
You need to install the missing components (e.g. VisualC++ 2005 Redistrbutable).

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

Running Windows XP service pack 3. Updated Firefox from 8.0 to 9.0. Now when Firefox opens "The URL is not valid and cannot be loaded" is displayed in a window and no home page appears. What's wrong?

That issue can be caused by an extension that isn't working properly.
Start Firefox in [[Safe Mode]] to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

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.

Please [https://bugzilla.mozilla.org/show_bug.cgi?id=713167 see this.] Installing [https://www.microsoft.com/download/en/details.aspx?id=5638 Visual C++ 2005 SP1] or the .Net Framework 3.5 SP1 may help mitigate the issue.

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.

I frequently get a "url is not valid and cannot be loaded" when I know the URL is valid

When searching or using previously validated bookmarks I frequently get an error message "url is not valid and cannot be loaded" How do I fix this?

You can modify the pref keyword.URL on the about:config page to use Google's "I'm Feeling Lucky" or Google's "Browse By Name".
* Google "I'm Feeling Lucky": http://www.google.com/search?btnI=I%27m+Feeling+Lucky&ie=UTF-8&oe=UTF-8&q=

New tabs keep opening spontaneously and I get the messsageThe URL is not valid and cannot be loaded.

This usually happens whenever I right click for a new tab or click a link. The unwanted tab always has the URL http://xn--3!1 -fua0do447bmv6g/#%C5%93%C3%8E%06%E2%80%99Ucr%C2%B7%C3%80 and I am constantly having to close these tabs.

Do a malware check with some malware scanning programs. 
You need to scan with all programs because each program detects different malware. 
Make sure that you update each program to get the latest version of their databases before doing a scan.

I am unable to use the about:permissions command from the url bar, when I use this command receive error message "The url is not found and cannot be loaded".

This was advertised as a new security feature in the nightly build . Is this true has this security been added to Firefox 5.0 or only certain Firefox builds ?

Yes, that about:permissions page has recently been added to the Nightly builds (7.0a1), but the Aurora builds (6.0a2) have it as well. I don't think that Firefox 5 will get it.
