Google provides a different key to differentiate installed copies of Google Chrome (standard or "Google Chrome for Work") in this file:

"/Applications/Google Chrome.app/Contents/Info.plist"

Google Chrome:
<key>KSBrandID</key>
<string>GGRM</string>

Google Chrome for Work:
<key>KSBrandID</key>
<string>GGRO</string>

Is there such an identifier on Firefox vs Firefox ESR?

Thanks, Don

Hi,

I am developing a website of my own and in that website I want to implement a handler for Content-Security-Policy violation reports. I want to test if this handler works as I expect and therefore I have configured a webpage such that is will report CSP violations (I see them in the web developer console) and I want to have them sent to my application's CSP-violation handler.

In my test environment, the application is running on localhost. I have run my web application both on HTTP and HTTPS (with a self-signed certificate), but in neither case Firefox is sending any reports to my application.

My CSP headers look as follows: Content-Security-Policy: report-uri http://localhost:5281/csp-violation;base-uri 'none';default-src 'self';form-action 'none';frame-ancestors 'none';report-to csp-viol;script-src 'unsafe-eval' 'nonce-9FuQ3NuVoW66DT1ZU4w9EPSymnHE1/hg';style-src 'unsafe-eval' 'nonce-9FuQ3NuVoW66DT1ZU4w9EPSymnHE1/hg' Reporting-Endpoints: csp-viol=http://localhost:5281/csp-violation Report-To: {"group":"csp-viol","max_age":10886400,"endpoints":[{"url":"http://localhost:5281/csp-violation"}]}

When I run my application using HTTPS, all HTTP in the endpoints will also be HTTPS.

I have verified that when I post something by hand to http://localhost:5281/csp-violation, my handler is executed, so that is not the issue. I believe that Firefox is just not sending the reports. Is there a way to configure Firefox such that it will send the CSP violation reports to my application when run on HTTP(S) on localhost?

Sincerely, Marcel

Hi,

more Details concerning the problem you can see here ! It should be great if you could help us with some diagnostics, for example why the problem only appears with FF on Linux, not with FF on WIN.

STR:

1. Launch Linux FF
2. Visit this page "Potential issue with plugin PITM" (Preview here
3. Because you will need an Account for visiting account please follow "Konto eröffnen" (Create Account) instructions).
4. After my approval for the account please visit again "Potential issue with plugin PITM"
5. Click "1.png" Below heading "Attachments", that should work without problems.
6. Close image view
7. Move Mouse pointer to image below heading "My test with a screenshot" – should become magnifier
8. Now Click that image

  » Expected (and so it does with WIN): Big image opens in new TAB
  » Actual:  New TAB opens, but without image view.

What are your results? FF Linux Problem or something else?

Secure connection failed and Firefox did not connect Firefox Last updated: 01/16/2024 39% of users voted this helpful

This article explains why you may see a Secure Connection Failed or a Did Not Connect: Potential Security Issue error page, and what you can do.

   If you see a Warning: Potential Security Risk Ahead error page, see What do the security warning codes mean? and How to troubleshoot security error codes on secure websites.
   To troubleshoot other error messages, see Websites don't load - troubleshoot and fix error messages.

Secure connection cannot be established

When a website that requires a secure (HTTPS) connection tries to secure communication with your computer, Firefox cross-checks this attempt to make sure that the website certificate and the connection method are actually secure. If Firefox cannot establish a secure connection, it will display a Secure Connection Failed or Did Not Connect: Potential Security Issue error page. Secure Connection Failed

A Secure Connection Failed error page will include a description of the error and a Try Again button. There is no option to add a security exception to bypass this type of error.

Hi, To who it may concern, a big thank you. I am a longtime Linux Firefox user. I had a secondary password, but somehow it has been deleted. I have changed my primary password and I have full access to Gmail, Youtube and other Google pages. My email address has always been the same for many years. It is recognised by Firefox when I type "My account on Firefox" though I am not allowed to enter another secondary email address.

I am almost 80 and not very computer literate.Kind regards,

Patrick Van Niekerk.

I have been trying for a house but won't open, so I tried another Browser and the Email account opened first time. What have I done work or what can I do to fix. Firefox is my #1 Browser. Email removed for privacy

I just installed 3 Add-ons Free Memory, Free Memory Button and Ramback but, apart from them showing on the Add-ons Manager, I can't find them let alone open them.................Does anyone know where they could be or what happened? Thanks in Advance

All of a sudden when I open Firefox a dialogue box from Software Update appears and asks for permission to make changes to my computer-- never happened before. My preferences are set to automatically update and my app list says I have the latest version of Firefox (129.0.1). I've checked Firefox properties and there is nothing selected under compatibility mode (I read on the forum this could cause the pop up). I can’t figure out what changes Firefox’s Software Update wants to make if I already have the latest version (so I always say no). The Firefox update to 129.0.1 was 8/14 but this dialogue box only appeared a few days ago. Is Firefox just not working because it’s not getting the automatic update message sent to maintenance? Do I need to uninstall and reinstall the maintenance program? And if so, how do I do that? (Windows 10)

I get this msg from FIrefox when I try to login from the webpage kp.org. I have no problem on Microsoft Edge.

"The page isn’t redirecting properly"

Also on NBCwashington.com/weather the video doesn't play on Firefox but does on Microsoft Edge. I contacted NBC Washington local station and they can find no problem on their web page.

Edge and Chrome directly open embedded government pages, such as https://www.nifc.gov and https://hazards.fema.gov/nri/map, that "Firefox Can't Open." "To protect your security," Firefox requires each to be opened in a new window. This is an incentive for users to switch to Edge or Chrome and stop using Firefox. All .gov pages should be safe to open even if they do not "utilize x-frame options or a content security policy to control whether other websites can embed them."

I realize I'm an old man with diminishing cognitive abilities, but y'all don't make this easy. I added the map extension, now how do I find it to use it? Why are there not icons like I had on Google?
