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")

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 helpThat 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).

After loading Firefox 4.0, I changed the address bar search engine to Google Search by Name, so I'd be taken straight to the most relevant webpage when I type in a word.
It works fine when I type in one word, but if I use a search with more than one word (e.g. "yahoo mail" or "google maps") I get an alert saying "The URL is not valid and cannot be loaded". Is there any way I can fix the address bar to accept multiple word searches?
I've tried disabling all my add-ons, but it didn't make any difference.Hi, this should sort out your problem:
1. Type in "about:config" into the address bar, this will open the settings menu. Click on "I'll be careful, I promise!"
2. Search for "keyword.URL" in the filter bar.
3. Enter "http://www.google.com/search?btnI=I%27m+Feeling+Lucky&q=" into the value field.
I'm no expert, but I had the same problem which got on my nerves after being so used to being able to type anything in, and following these steps fixed it. -
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.

Tried to open Private browsing and get message "the url is not valid and cannot be loaded"
up graded Firefox directly from older version to latest version and problem cropped up. Latest version on my laptop which is out of service and in shop works fine and on my net book works fine. Should I have done it in steps?

I get this message quite often. I know the urls are valid because I visit the websites everyday. People have told me that maybe Firefox just doesn't support those websites very well and to try a different browser. It's driving me crazy. Any ideas?

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.

Do you have that problem when running in the Firefox SafeMode? <br />

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.

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. -
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... -
Since I downloaded the last Firefox version 3.6 15, no matter where I am, I am back in my homepage and I get the message "The URL is not valid and cannot be loaded", usually I can go back to the site I was in and keep doing whatever I was doing, but often it will happen again.
This is happening in both my computer, laptop and desktop, one has windows XP, the other one has windows 7.
Suggestions? It is becoming a nuisance being moved from the tab I am, and kicked back to the homepage tabStart 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).

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.

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 12.0Wow! 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.
