Firefox works fine, but Chrome refused to work at all "No internet connection" while Firefox was working! Same problem with some reinstalled software, "Make sure you internet connection is active" Internet connection is always on when computer is on Adobe Connect ran into similar problem, and transferred to another page asking for the web address when the video conferencing was taking place, I have never had that problem before the browser or Windows update

Hi,

You say that you're having a problem with Chrome and not with Firefox - as you're posting this on the support forum for Firefox, may I suggest that you post your question here :

https://productforums.google.com/forum/#!forum/chrome

And / or :

That's strange! Normally Firefox will piggyback on your Windows "LAN" connection settings. However, it's also possible for Firefox to use a different connection method based on what is entered in settings OR as a result of a particular extension. This may or may not be helpful in understanding the difference. I'll put steps for looking at those below the line.

Does your security software intercept browser communications for filtering? This can be set on a browser-by-browser basis, so that might result in a difference.

Malware is another possibility. You could run some additional cleaners to supplement your regular security software. Our support article lists products other users have found helpful: Troubleshoot Firefox issues caused by malware.

Finally, just a note about website certificates. Firefox uses a separate certificate store from IE, Chrome, Edge, and other programs that connect via the shared plumbing of IE. If you notice any certificate errors in Firefox on well-run sites, consider that a red flag for further investigation of an attempt to infiltrate your Firefox connection.


Connection Setting

  • Windows: "3-bar" menu button (or Tools menu) > Options
  • Mac: "3-bar" menu button (or Firefox menu) > Preferences
  • Linux: "3-bar" menu button (or Edit menu) > Preferences
  • Any system: type or paste about:preferences into the address bar and press Enter/Return to load it

In the search box at the top of the page, type proxy and Firefox should filter to the "Settings" button, which you can click.

The default of "Use system proxy settings" piggybacks on your Windows/IE "LAN" setting. "Auto-detect" can lead to a flaky connection. For many people, "No proxy" is a good option.

Extensions

You can view, disable, and often remove extensions on the Add-ons page. Either:

  • Ctrl+Shift+a (Mac: Command+Shift+a)
  • "3-bar" menu button (or Tools menu) > Add-ons
  • type or paste about:addons in the address bar and press Enter/Return

In the left column of the Add-ons page, click Extensions. Then cast a critical eye over the list on the right side. Any extensions Firefox installs for built-in features are hidden from this page, so everything listed here is your choice (and your responsibility) to manage. Anything connection related?
