I received the following error when attempting to use HP SimplePass Identity Protection to manage my passwords; Firefox doesn't know how to open this address, because the protocol (dpql) isn't associated with any program. How can I correct this?

I use HP SimplePass Identity Protection to control my passwords. Everything was fine until I updated to Firefox 4. Can I remove version 4 or is there a solution to my problem. I received the following error message; Firefox doesn't know how to open this address, because the protocol (dpql) isn't associated with any program.

You'll have to downgrade to the previous secure version I regret to say. See https://support.mozilla.com/en-US/questions/799388
Go to [http://www.mozilla.com/en-US/firefox/all-older.html Download Firefox v3.6.17] and download it to the desktop. 
Then go to Add/Remove Programs, scroll down to "Mozilla Firefox" and remove it, choosing to keep your bookmarks, customizations etc., (don't checkmark the box). 
Then reboot and delete the folder called "Mozilla Firefox" at this location: C:\Program Files\Mozilla Firefox 
Finally run the installation file you downloaded to the desktop earlier. 
Your bookmarks, customizations etc., are maintained in a different location and will become available to you again once you complete the installation. 
After you complete the installation, go to the [http://www.mozilla.com/en-US/plugincheck/ Plugins Check] page and update those where necessary.

HP Protect tool password manager not working with the new version of Mozilla: I got this alert: "Firefox doesn't know how to open this address, because the protocol (dpql) isn't associated with any program." please help

I have an HP ProBook 4520s. I have been using HP Protect tool's Password manager to store and manage my passords for all Login websites in Firefox 3.6. As a result, I just swiped my fingerprint to log on to any website.
After I installed the version 4 of Firefox, my all my login details do not work anymore. I have tried to reset them but I repeatedly get this error: "Firefox doesn't know how to open this address, because the protocol (dpql) isn't associated with any program."
something like this would have been passed onto the address: "dpql://c:\program%20files%20(x86)\hewlett-packard\hp%20protecttools%20security%20manager\bin\dpminionlineids.dll/qlinkload.htm#id=2".
Although the password manager works with Internet Explorer 9, I need it to work with Firefox 4 as this is my preferred browser.
Please help. Thank you!

I guess this means that IE is more user friendly for HP Password Manager finger swipe recall of passwords, a favorite of mine. I still don't see a post from Firefox as to why they haven't produced fix. So I'll switch to IE until things change. I don't see value in downgrading to a Firefox version that's no longer going to be supported.

Since I updated to Firefox 4.0 I no longer can use the fingerprint scanner to log into websites. I get a message saying the protocol dpql isn't associated with any program. It was working fine upgraded. What do I do now?

The scanner works fine with Explorer and worked fine with Firefox before the upgrade. I find it disconcerting that you upgrade something that then changes how I have to use my computer in ways that have nothing to do with Firefox. At least we should have been warned prior to the upgrade that this was going to happen.

Id this the HP SimplePass Identity manager or Digital Persona fingerprint reader? If it is, the company that make the fingerprint reader have abandoned it. For more details see https://support.mozilla.com/en-US/questions/799388

With Vers. 4 I can no longer use my HP SimplePass Identity Protection, allowing me to use my fingerprint to log into websites. err mess. "Firefox doesn't know how to open this address, because the protocol (dpql) isn't associated with any program"

the question is sufficient

The company that make the bioscanner for HP have abandoned it. For more details see https://support.mozilla.com/en-US/questions/799388

Hi le.hamzou,
Previous suggestions were to update the Security Manager if there was one. There were also these add ons:
[https://addons.mozilla.org/en-US/firefox/addon/fingerfox-se/ Fingerfox], but I am not sure if it will work on win8, it does on win7.
Another work around I saw was [https://addons.mozilla.org/en-US/firefox/search/?q=ietab&appver=29.0&platform=all IE Tab].

Getting this error message Firefox doesn't know how to open this address, because the protocol (ableton) isn't associated with any program

Firefox doesn't know how to open this address, because the protocol (ableton) isn't associated with any program.
I keep getting this message even though the ableton software was installed and authorized

Protocol error usually indicates that the very leftmost part of the URL is not recognized.
So http://, ftp://, rtsp://, usually work.
ableton:// would need to be added by some software somewhere...
Can you get instructions from the vendor? Does these posts seem relevant:

When trying to go into itunes I get this message "Firefox doesn't know how to open this address, because the protocol (itmss) isn't associated with any program"

When trying to log into itunes i get this message:
Firefox doesn't know how to open this address, because the protocol (itmss) isn't associated with any program.
I had to reset Firefox (due to slowness and shockwave error message that I kept getting). Itunes was downloaded after the reset, but I can't get into it? Any ideas?

I ran into this same problem after Firefox auto-updated to v24! I'm on the Beta Channel and I had Firefox set to automatically update.
What I did to correct the problem:
1. Turned off all automatic updating.
Options> Advanced> Update [tab]
Firefox updates
[x] Check for updates, but let me choose whether to install them
[ ] (unchecked) Use a background service to install updates
I also unchecked;
[ ] Search Engines (I will turn this back on after I'm done with my experiment.)
2. Googled 'Firefox v23 download', downloaded and installed: Firefox_Setup_23.0b1.exe (version 23, Beta 1)
Since I reverted back to v23, I haven't had any problems.

Start Firefox in [[Safe Mode]] to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

Can't open any links within my emails. The display reads, "Firefox doesn't know how to open this address, because the protocol (blockedhttp) isn't associated with any program." How can I fix this?

Can't open any links within the emails using Firefox. I can open them in other browsers however. The message reads, "Firefox doesn't know how to open this address, because the protocol (blockedhttp) isn't associated with any program.". How can I fix this?

Looks like blocking software to purposely block a page by messing with the url.
*http://kb.mozillazine.org/Parental_controls
*http://kb.mozillazine.org/Blocking_sites (more links)

When i click on a hiper link, i get the following response: firefox doesn't know how to open this adress, because the protocol (blockedhttp) isn't associated with any program.

when i click on a hyper-link, i get the following response: firefox doesn't know how to open this address, because the protocol (blockedhttp) isn't associated with any program.
My question is: how do i get this hyper-link to open?

You have blocking software to change the url to prefix blocked to the url to get '''blockedhttp:''' to prevent you from opening the file. It might be the "Blocksite" extension, but I just typed in something I blocked into the location bar and I didn't see that happen. but that might not be the same as clicking on a link.

Maybe it's from the blocked sites list used by Firefox and other browsers maintained at google, or a parental controls application.

Hi,
You may have to install the Spotify application on the laptop to get Spotify protocols recognized.

I am getting this error message when trying to get to a college webpage Firefox doesn't know how to open this address, because the protocol (html) isn't associated with any program.

I am trying to get to a college webpage for information and get this error message from firefox Firefox doesn't know how to open this address, because the protocol (html) isn't associated with any program.
== This happened ==
Every time Firefox opened
== whe trying to access webpage

Is this coming from a link, or from something you are trying to type in the address bar?
Try replacing the "html" at the start with "http",
so if you have html://somesite.edu,
change it to http://somesite.edu.

I downloaded Newest mozilla yesterday, adobe updated, and now when I click a YouTube video I get a box saying "Firefox doesn't know how to open this address, because the protocol (rtsp) isn't associated with any program." and can't watch any videos?

I downloaded the latest version of Mozilla Firefox yesterday, full and complete, and I am actually using it right now. The only problem I have had is upon clicking any YouTube video, the box pops up saying "Firefox doesn't know how to open this address, because the protocol (rtsp) isn't associated with any program." But there are no directions or suggestions on how to address this problem. Ive looked at YouTube add-ons and none of them really seem related. Upon the finish of the new Mozilla, I also was prompted to upgrade the flash player, and did so without any trouble. I am only guessing this is an extension/plug-in problem. I really am quite confused!
