Cannot open http://192.168.0.100/ address in Firefox v82. "Try again." Is it blocking because HTTP?

My older Samsung printer also runs a web server at its LAN address for administering it.

I've always been able to login from other computers on my local network to check toner, see page counts, and so on.

There is no "force Firefox [v. 82] to connect via HTTP" in my case.

Every single attempt to access http://192.168.0.100 is rewritten by the browser to https://192.168.0.100 which I gather requires a certificate to be presented--which the old printer does not offer--after which Firefox declares "Try again."

Is there a way around this so I can get back to what used to work?

Thank you.

There shouldn't be a problem to access the router via the http:// protocol.

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or userChrome.css is causing the problem.

  • switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
  • do NOT click the "Refresh Firefox" button on the Safe Mode start window

You can remove all data stored in Firefox for a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History -> Show All History" or "View -> Sidebar -> History").

Using "Forget About This Site" will remove all data stored in Firefox for this domain like history and cookies and passwords and exceptions and cache, so be cautious. If you have a password or other data for that domain that you do not want to lose then make sure to backup this data or make a note.

You can't recover from this 'forget' unless you have a backup of involved files.

If you revisit a 'forgotten' website then data for that website will be saved once again.

Thank you, cor-el.

Wanting to be doing something myself I installed and ran chr*m??m (Ubuntu 20.04 64-bit here) with the same result: negative.

"This Is Not a Firefox Problem Pointing Then At Pilot Error. I Apologize." There. I've said it.

The printer responds to ping and more importantly prints. (The only printing on this Samsung M2020W model is over wireless, and one of those ways is configuring it as a wireless network printer.)

I'll follow your Safe Mode instructions, not least to experience the process of taking the plug-ins out of the equation.

Again, I apologize. I should have done more testing before slinging accusations around like I had--suddenly--gotten my first clue. Ever.

If I find the cause, I will certainly report back because I'm probably not the only conclusion-jumper left on the net... ;^) Thanks. -- David
