The full message is: "Firefox doesn’t know how to open this address, because one of the following protocols (rtsp) isn’t associated with any program or is not allowed in this context.

   You might need to install other software to open this address."

I'm running Windows 8.1. I refreshed Firefox, and I disabled and deleted all AddOns. i don't know what else to do. The problem started when I installed Norton for Firefox, and now I can't get YouTube videos to play. Thank you!

When I click to play the track sample, the little circle goes round, but there's no sound coming out. Other sites like Youtube work fine. I'm using Windows 10 with Flash ad-on, on a new build PC. The flash setting is set to "ask first", but I don't think it gets that far. It was just the same before I installed flash.

When I updated from FF v60.01 64-bit to v61.0.1 on my Desktop with Win7 SP1 64-bit Firefox ignores my Users\... Profiles\hrwugr05.default*\chrome\userChrome.css file scripted as follows:


@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */

statuspanel { display:none!important; }


I really hate that statuspanel nag flashing in the lower left of my screen when watching movies online. I've reverted back to FF v60.0.1 for the css file t to work.

Is there a different Script needed for FF 61 or a bug you need to fix?

Thanks

I get this error message almost daily when I try to access Natwest. I know I can fix it by clearing cache but then I have to reset all the autofill data, re-enter search criteria, etc. I find it hard to believe there is any problem with Natwest's security set up? Is there a simple fix for this, please?

Firefox.app shows the correct icon in the List view in a Finder window, however in the Icon view, Info, and in the Dock all shows the generic App icon. This started to happen only recently so I presume it's to do with the version 60.0.1 update. My OS is macOs 10.13.4

I noticed that on my new computer, backgrounds created in CSS with the background-image property are oversaturated.

In the example, there's a square with a background color that is the same as the start and end colors of the gradient of the body element behind it.

On my screen, the background is more saturated than the square. This does not happen in Chrome or Safari, where everything looks like the less saturated square.

What I've tried so far:

Checked with the same Firefox version on my MacBook. The background color gradient was rendered the same as the solid background (however more saturated than in Safari and Photoshop).

Disable hardware acceleration. This had no effect.

Restart Firefox in safe mode. This had no effect.

Enter a value for gfx.color_management.display_profile: the path to the color profile that my iMac shows in ColorSync Utility>Profiles>Computer>Displays>iMac. This had no effect.

Change gfx.color_management.mode from 1 to 0 and restart Firefox. All yellow on the linked page looks more saturated than in Chrome and Safari, but the background gradient is rendered in the same color as the div with the solid background. The same happened after changing the setting to 2.

Interestingly, one could argue Chrome and Safari render the colors undersaturated, because when I create the color in another program, it looks identical to the rendering in Firefox. However, I would assume it would be beneficial to have color management activated and in that case, the background gradient should not look different.

I have attached an image that shows the effect on my display.

How can I get internally consistent color rendering with Firefox color management enabled?

Videos in Facebook show black. My drivers are up to date. The same videos play on my laptop, but not on my desktop. All software on both computers are the same, Windows 7. When I chose "restart Firefox with add-ons disabled" it works, however I already disabled all add-ons, so I cannot pinpoint on an add-on as the source of the problem. The videos play with Chrome and IE, but not with Pale Moon. It plays in Pale Moon when restarted in safe mode.

Hello,

I'm having issues with a certain website and thought cached data might be to blame. However, when trying to clear said data, I found that both Clear Data and Manage Data are greyed out. I disabled all of my addons and restarted FF, the issue remains.

I'm on FF 60.0.1, Windows 10 x64 Pro up to date. I'm not using "Always browse privately".

Any help is greatly appreciated.

Thanks.

Hello, I want to prevent third parties accessibility services to enter my browser. But the way this checkboix is formulated confuses me. If I check the box 'prevent accessibility services from accessing your browser' is it then enabled or disabled? What are the accessibility services here? I read all the instructions but still find it a confusing sentence to check or uncheck?

Should I read the sentence as "prevent Firefox Accessibility Service from accessing your browser'? Or should I read it as "prevent any type of physical impairment assistive software from accessing your browser?

Hope you could help me with this. And if so it could be nice to make this sentence a bit clearer. Or maybe I'm just a bit confused and you should just leave it like this;)

Best,

Art

I was using Firefox while my PC crashed. So I had to force-restart it. After I reopened Firefox, I was asked to reconnect to my Firefox account to sync it. When I typed my password (which I was 10000% sure that it is correct), it said that it is wrong. So I reset it. After I connected to the account, I was surprised that all my saved passwords in my Firefox account disappeared. My bookmarks were there, nothing happened to them. Also, synchronizing Logins was checked in the sync settings, so I really didn't find any explanation for that!

Ever since I upgraded to Quantum (Mac OS 10.13.3), the Amazon website is extremely slow. Every single page stalls/hangs and I have to wait several seconds to continue. This does not seem to happen with other websites, and it does not happen in other browsers. It is extremely irritating since I am often on Amazon. I've tried restarting in safe mode and the problem persists.

I have ten websites I visit daily (they are set up in my homepage); a half-dozen of those sites are set to remember me so that I am already logged on to those sites when Firefox comes up.

The past several weeks that automatic login has not been working (although it DID work for THIS website, which is NOT in homepage). I have to log in to each website every time I bring up Firefox and visit those websites, and I tell them again to remember me. If I open a new tab and go to a website again after having logged-in to the website in the original tab, I am already logged-in. If I close the Firefox window and bring it back up, I am back to having to log in manually to every website.

I tried using Chrome as a doublecheck, and the issue is not present in that browser.

So I am thinking the issue may have started with release 60.0.1. I do not see issues within my Firefox settings, shown below, but I am not terribly knowledgeable, either.

I've cut the cable and now use my computer to stream content to my television. My problem (annoyance, really) is that every time I link into a website, I've got to enable Flash player in order for the content to play. Is there a way to blanket turn it on for all sites instead of each one individually? It's especially annoying when I have to enable it for the same page over and over again, though not with every page. Any advice appreciated.
