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

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.

Hey

Iam not able to start the moz firefox browser. I think because of a broken profile. Unfortunately iam not abke to fix this. If i try to open the profiles (windows+r: firefox.exe -p) nothing happens.

What could I do?

Thx

I'm clearing space on my hard disk. I discover FF has 2 profiles, both with default-release as part of their names. One was last modified today, and one last modified a few months ago. I've not knowingly done anything to create a profile in that period. Why have I got two, and can I delete the older one?

Many thanks
