Firefox allows you to set how and if you get updates. The setting is under Options.

How do you completely turn off update checks in Firefox v64? You can use a policies.json file to disable updates for all users. https://github.com/mozilla/policy-templates/blob/master/README.md or https://winaero.com/blog/disable-updates-firefox-63-above/

You can use a policies.json file in the distribution folder in the Firefox installation folder instead as also listed in the article, so no need to use GPO keys in the Windows Registry. • https://support.mozilla.org/en-US/kb/customizing-firefox-using-policiesjson

If I attempt to access my router using 192.168.1.1 Firefox automatically changes the address to https://192.168.1.1.

If turning off HTTPS Only mode (or making a site exception for that feature) doesn't resolve it, does the error page explain why Firefox used HTTPS? Please copy/paste the error page text into a reply.

If only any of those methods actually worked! You need to understand that most, if not all the solutions offered never worked at the time, and are now obsolete for later versions. Please don't insult my intelligence with further outdated and non-working options. Regarding the error page request. 1. How do you do this? 2. Why is it necessary when previous versions didn't have the problem? 3 Why don't the HTTPS options work?

Well, I wonder why your superior intelligence hasn't yet prevented you from not using Firefox anymore. Do you like getting "insulted" by the "crap" us "morons" give you?

The people who answer questions here, for the most part, are other users volunteering their time (like me), not Mozilla employees or Firefox developers.

If you need to file a bug report or feature request for Firefox and other Mozilla products, see File a bug report or feature request for Mozilla products for details.

Regarding the error page request. 1. How do you do this? 2. Why is it necessary when previous versions didn't have the problem? 3 Why don't the HTTPS options work?

For #1, you select and copy the text from the error page using the typical methods you would use to select and copy text from any web page. Then paste into a reply here. You can obfuscate the IP address (if it appears in the error text) before posting.

For #2, we don't have enough information to diagnose your error or answer this question.

For #3, do you mean the HTTPS Only feature? It should work the way the article describes. If it doesn't work the way the article describes, where is it going wrong? This is the article I'm referring to: HTTPS-Only Mode in Firefox.

So, I assume that in order to copy and paste from an error page you first need to view an error page, whatever an error page is? So let me rephrase my question: How do I get to view an error page in order to cut and paste the information you have requested when no error page is displayed? Lets not forget that any mention of an error page is of your own making and has nothing to do with my query. But, hey, don't have a go at us when we waste your time because we're volunteers, who don't understand the product but should, and don't know when invalid comments are just a waste of time, because it makes you feel important.

You started this thread by saying that "If I attempt to access my router using 192.168.1.1 Firefox automatically changes the address to https://192.168.1.1"

Since you're saying that address didn't work, Firefox probably displayed an error page explaining why it didn't connect. No?

Your assumption is entirely incorrect!!!! I input the address 192.168.1.1 Firefox changes this to https//192.168.1.1 meaning I cannot access the router GUI Nothing else happened. There was no error generated, why would there be? If I input www.totalcrap.com I get redirected, not an error. It is not an error to input ANY address. Although, if you try it you will find that the https is not added. So it must be a software modification that decides users can longer communicate with their networked equipment in Firefox, but can in other browsers. Go Figure! And before more numpties put forward more unwarranted inputs: I HAVE SET OPTIONS TO NO HTTPS! I WOULD NOT HAVE THIS PROBLEM IF I WASN'T FORCED TO UPDATE A WORKING SYSTEM THAT DID NOT REQUIRE UPDATING.

You saw a change in the address bar and never submitted it that address, so you have not seen what Firefox would say about its attempt to connect to https://192.168.1.1/ . Are you willing to try it to see whether Firefox gives an explanation for its behavior?

Also, instead of entering just the bare IP address, can you try using the full URL

http://192.168.1.1/

and see whether Firefox modifies that?

Firefox does [profanity] all to any HTTPS address input!!!!!!! Why would it? Why would manually entering an address generate an error? Try bbc.co.uk and you get https://www.bbc.co.uk/ in the address bar. Is this an error? NO! So why would Firefox automatically generate an error for every address bar entry? But 192.168.1.1 will not connect to a device that requires firmware updates just to deal with Firefox's use of https. Contact ASUS and request they update ALL their network devices to deal with Firefox amendments and see how far you get! Before the additional of forcing HTTPS whatever the setting, Firefox NEVER added http to a device IP address. So why does it do it now? And, in answer to my question, which is what you should be dealing with, is how do I get it to stop doing so when the settings which should prevent it don't do anything? I am still waiting for a definitive answer to a setting or group of settings that stops Firefox from updating and adding this type of bug to an otherwise working program that did not require updating. I assume that no one actually knows enough to be able to stop updates.
