URL is not valid and cannot be loaded pop-up problem has started again and I can't find any reference in FF Help. Do I have to scroll thru 23,000 support questions asked?

This problem HAS happened before, maybe 1.5 yrs ago. While on a valid page a pop-up saying URL is invalid and can not be loaded appears. Frequency starts increasing in time. Then I can not load any of my bookmarked pages without re-starting my laptop. Has been getting worse since last FF update.

well after 4 days and no support help, I said screw it. Good bye FireFox, your excellent customer service on this issue drove me to install Google Chrome. Just like Opera's piss poor customer support drove me to FireFox, now Firefox is driving me elsewhere.
This issue is NOT AN ADD ON issue, nor THEME ISSUE, its a FIREFOX ISSUE, but their lack of a fix is inadequate for me. I hate the damn annoying pop up every time I open firefox so I will dump firefox and move on after 5 yrs.

My dropped Macbook plays a five note song three times and on the third time, the last note drops in pitch like it is dying. I have not shut it off, but it does this coming out of sleep mode. Can't find any references to this. Anyone know what's happening?

Mostly because you are not using any capital letters or paragraph returns and your post is difficult to read.

This issue can be caused by an extension that isn't working properly. 
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")
Other things that need attention: 
Your above posted system details show outdated plugin(s) with known security and stability risks that you should update.

In Hotmail, my "To:" button does not work and I can't attach any files. Their help sections said to contact you to help solve my problem. Help.

In my Hotmail account I am unable to use any of the buttons like, the "to" button, or the "attachment" button. At the Hotmail help section, they suggested contacting my browser help service.

Sounds like your drop did break something. You can go to an authorized Apple service center and get it repaired. I believe the out of warranty costs for repairing an iPhone 4 is about $149, but you would need to check with them to be positive. If you have Apple Care+ and it's still active, you should be able to use one of the $49 events to get your iPhone repaired.

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?

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).

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.

How do I enable Firefox 4 to do a search on more than one word (e.g. "yahoo mail") without receiving the error message "the URL is not valid and cannot be loaded"?

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.

Continously get an alert: "URL is not valid and cannot be loaded."

Every time I open a new page I see this error. Could it be connected to the Google Chrome add-on? I see that add-on the first few times I open a new tab then it disappears and I start getting this error.

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=
* Google "Browse by Name": http://www.google.com/search?ie=UTF-8&sourceid=navclient&gfns=1&q=

Why do I constantly receive a pop up telling me "this URL is not valid and cannot be loaded?" How can I stop this pop up?????? HELP!!!!!
== This happened ==
Every time Firefox opened

Do you have the Google Toolbar installed? If so, go to '''Tools > Add-ons''' > Extensions''' Select the Google Toolbar, click '''Disable__ then restart Firefox.

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?
