Is it causing any other issues except for errors in your log? It seems the website has some coding issues it needs to have fixed, I think. And the favicon is just broken, so it can't load it. Some websites will produce errors in the console, especially if you have stricter content restriction policies in place

if it's causing crashing and errors then that would be useful to know, too.

Thanks for the quick response. I have been having problems over the mast month, which is why I have been deleting and reinstalling it. The favicon warning comes up for a number of other websites too, at the moment the computer is running, but I am just looking for things to avoid the previous problems.

The console shows a number of things and I do not know if any would cause a crash.

Just now Youtube caused a" Exception { name: "NS_ERROR_NOT_AVAILABLE", message: "Component returned failure code: 0x80040111" message. Sounds ominous, no idea what it means.

Advice on how to prevent errors would be appreciated. It seems there is some issue with stacks?

I wouldn't sweat the console errors unless you start getting crashes again. Can you link the youtube video where that console message appeared? I wanna see if it happens to me, too.

I do not for the moment remember which one it was, but will try to get the error to recur. I will post when I can identify it.

The City Council site is http://www.tshwane.gov.za/sites/Departments/Public-works-and-infrastructure/Pages/Load-Shedding.aspx but I am not surprised that they have errors, their service is pathetic.

Yeah that site gives me errors too. Including "TypeError: $(...).ticker is not a function" Doesn't seem to affect the site much, though.

Makes you wonder, they are supposed to provide essential services. A few weeks ago the site was down for two days.

The Firefox seems to have stabilised for now, I am not getting errors. Maybe the devil has been exorcised. Thanks for helping, I will post again if it recurs.

If you try to load the favicon manually, it displays a message that it cannot load because it contains errors. Information for the image shows that it is 0 bytes.

Firefox seems to work normally for the moment.

Any comments welcome

Sorry to bother again. After a few days of good surfing, the Firefox ghost strikes again. It hangs on startup, no rindows open, and I get the messages:

NS_ERROR_NOT_AVAILABLE: Cannot call openModalWindow on a hidden window Prompter.jsm:437 NS_ERROR_UNEXPECTED: Component returned failure code: 0x8000ffff (NS_ERROR_UNEXPECTED) [nsIScriptSecurityManager.getLoadContextContentPrincipal] browser-custom-element.js:1278

Not sure about the references to Chrome, I uninstalled ever trace of Chrome I had on my Mac. Someone said I should reinstall Java, which I removed a year ago. Again comments would be helpful.

Chrome is what Mozilla has always called the browser UI elements. Nothing to do with Google Chrome browser.

Java has nothing to do with anything, unless you are using an application or using a site which uses Java to display an application. It has nothing to do with Javascript. People say these things for some reason.

It sort of looks like an error is occurring before any UI windows are available, which causes an error in displaying the modal dialog box for the error... But something seems to be an issue if Firefox itself (unless it is an extension?).

If you have crash reports, make sure they are submitted, and you may paste the crash reference number here for knowledgeable people to investigate.

Boilerplate crash instructions:

[If you can open Firefox] We're sorry to hear that Firefox is crashing. In order to assist you better, please follow the steps below to provide us crash IDs to help us learn more about your crash.

The crash report is several pages of data. We need the report numbers to see the whole report.

1. Enter about:crashes in the Firefox address bar and press Enter. A list of Submitted/Unsubmitted Crash Reports will appear, similar to the one shown below.
2. Copy the 5 most recent Submitted Report IDs that start with bp- and then go back to your forum question and paste those IDs into the "Post a Reply" box.

Note: If a recent Report ID does not start with bp- click on it to submit the report.

(Please don't take a screenshot of your crashes, just copy and paste the IDs. The below image is just an example of what your Firefox screen should look like.)

Thank you for your help!

More information and further troubleshooting steps can be found in the Troubleshoot Firefox crashes (closing or quitting unexpectedly) article.

Thanks in advance!

Thanks for the advice. No joy, thre are no submitted chrash reports, although a number of times there were reports to Apple after a crash. All I find in the Crash Report folder is an empty folder called events, and two files called InstallTime20191202093317 and InstallTime20191030021342.

There is also some problem with MS Word and with the OS somewhere. It has been ok for a while, but I suspect I am going to have to reload the OS at some stage. So if a solution is not evident then let me try again in the new year when the stars may be better aligned.
