I'm using Firefox, and while setting up a server, I have been fiddling around with redirects. Now, Firefox has cached a 301 redirect from http://example.com/ to https://example.com/ and from http://sub.example.com/ to https://sub.example.com/.
I've tried the following things:
History -> Show all history -> Forget about this site.
Checked that no bookmark with https://example.com/ is present.
Changing browser.urlbar.autoFill to false in about:config.
Changing browser.cache.check_doc_frequency from 3 to 1.
Options -> Advanced -> Network -> Chached Web Content -> Clear now.
None of the above works, so I checked the redirect with wheregoes.com and it doesn't show any redirect from http to https.
I've even changed the DNS to point to another IP served by a server, where I've never set up redirection - the redirection is still in effect.
I've also tried in Private Browsing in Firefox, and there is no redirect there. I've tried in Google Chrome, and there is also no redirect here.
I've also tried to make a redirect from https to http which worked in Google Chrome, and yielded a redirection error in Firefox.
My version of Firefox is 38.0.1, and I'm using Windows 8.1. I use the following addons: AddBlock, Avast! and LastPass. Avast! may not be the issue, as I've disabled it while testing.
What I can do about it?
"Sites preferences" are the culprit. Wasted 45min of my life finding how to fix it despite all the kb/support.mozilla tricks which does not solve your issue nor did mine. I don't know what triggers this issue, but several of my websites started to go pear-shaped in a few weeks only affecting me and only firefox.
That's the solution you are all looking for:
Go to Preferences
Privacy
Click 'Clear your history' (nothing will happen yet, click safely)
Once the pop-up appears, click Details.
Untick everything except 'Sites Preferences'
Select 'Everything' in the select box at the top
Click Ok
Try now
PS: What I did try that did not worked for me are:
urlbar.autofill false
Forget Website trick
Safe mode
We all know it is not an HSTS issue when a website you own and you accessed before never got https support but now FF wants you to use https... It is just a firefox bug IMO.
The solution that worked for me:
Go to about:config
Look for network.stricttransportsecurity.preloadlist and set it to false
Enjoy
If the above STILL DOES NOT WORK, try setting browser.fixup.fallback-to-https to false from about:config
Using Firefox 100 or above you may also need:
dom.security.https_first to false
dom.security.https_first_pbm to false (this one is for anonymous windows)
I had the same problem but the answer was that I used a .dev extension to access my local websites !
I cleared all historic data in FF and nothing changed.
Searching for another solution, I found this page https://ma.ttias.be/chrome-force-dev-domains-https-via-preloaded-hsts/
With .dev being an official gTLD, we're most likely better of changing our preferred local development suffix from .dev to something else. If you're looking for a quick "search and replace" alternative for existing setups, consider the .test gTLD, which is a reserved name by IETF for testing (or development) purposes.
I changed my local website extensions from .dev to .test and all work perfectly !
Alternative solution, easy.
Open Firefox and in the address bar type this URL
http://example.com/?fake_parameter_to_bypass_cache
This should force the browser to reload the web page from http://
None of the answers worked for me, the only the one was the one in the comment of Muhammad so thanks in advance to him, I copy the answer here to make it easier:
Go to about:config
Look for browser.fixup.fallback-to-https and set it to false
Check your extensions!
In my case, DuckDuckGo Privacy Essentials extension was causing this redirect. I disabled it, and the problem is solved.
Now (Firefox 84) it is much simpler to clear the site's data. Just click the padlock icon on the left of the address bar. Then choose "Clear cookies and site data".
I had the same situation as what OP did. It helped me to clear the HTTPS redirect.
Here's what worked for me on Firefox v98.0.2:
Settings -> General
Network Settings -> Settings
Uncheck "Enable DNS over HTTPS
I tried the 'correct' answer, plus the comment about including cache in the deletion, and I was still having issues with my problem site.
I opened the firefox profile directory and searched for the website name in all files.
I found it in 'logins-backup.json' and deleted that file to finally fix the problem.
In my case, I decided to use a *.dev domain for local development. But then I tried to open the site in Firefox, and after a while I realized it uses HTTPS, even when I start the url with "http://..." I tried to right-click on the link in the History, and choose Forget About This Site, or clear the cache. But it didn't help.
Later I found out that the dev domain is in HSTS preload list these days. Which means Firefox and Chrome (and probably others) don't let you access the subdomains w/o HTTPS. More on it here and here.
In my case, it was an addon that did it: disabling DuckDuckGo privacy essentials fixed it.
I had this issue when running Firefox with OWASP ZAP proxy.
I didn't knew it was the proxy causing this.
In hindsight it's easy to test this: run Firefox without OWASP ZAP proxy to see if it works.
To get it working with OWASP ZAP, turn off Heads Up Display (HUD) or enable the HUD only for URL's that are in scope.
My problem was caused by the HTTPS by default extension. There is a bug that opens HTTP bookmarks with HTTPS. To work around, open "HTTPS by default" Preferences pane and enter domain name exclusion.
None of these suggestions worked for me in Firefox v101. What worked for me is changing the value of security.tls.version.min from 3 to 1 in about:config.
[NOTE: After I changed this setting, Firefox initially redirected from http to https. But this time Firefox allowed me to "accept the risk and continue," which wasn't possible when security.tls.version.min was set to 3. --end note]

Lets get back to the old firefox that was amazing, the 3.6.
Nowadays is full of crap for us developers, and sysadmins.
I have tons of sites in intranet that cannot have a valid ssl, this is a major deal. I cannot download "deb" files because its a threat, i cannot this and cannot that... why? I am a power user i know what to do whit, why should I (we) be treated like the rest of the users?
The cache, i cannot disable the cache to 100% why?
In a blip of a second i will be using links as my browser.
Firefox should have a expert mode, where none of this crap happens.
I am mad with firefox and chrome. That is why i still use firefox 3.6 in a lot of cases, to bypass stupid restrictions.
Now, I had this issue on my workstation's development site. I had an old site that I still wanted to reference, and I couldn't get http to work for anything. There was not https binding, either.
Finally, I realized I had a url-rewrite in my webconfig that redirected all http to https...
hahahaha
Disabling https, is not an absolute in Firefox. Some sites will redirect and may not offer http.
However to choose one url over the other if it is an option you can disable autofil:
Address Bar Search In order to change your Firefox Configuration please do the following steps :
In the Location bar, type about:config and press Enter. The about:config "This might void your warranty!" warning page may appear.
Click I'll be careful, I promise! to continue to the about:config page.
In the filter box, type or paste autofill and pause while the list is filtered
Double-click browser.urlbar.autoFill to toggle it from true to false.
If I load a page on my Drupal 8 site with a reliable internet connection, the site will stop loading after about 20 seconds.
My server is on LAMP. How to get the page to load completely ?
It can be that your theme or some of the user modules is causing the issue.
Check under Reports -> Recent log messages to see if some error is logged.
Also you could try disabling theme or modules (temporary) to see if this will continue.
Then, under Configuration -> Development -> Performance see if the caching is turned on. It should be on for production environment.
In your browser go inspecting, go to "Network" tab and reload the page. See if there are some request that take unusually long time.
Ask some of your friends to test the site.
At end, host server may be really slow or miss configured... Check for logged errors on server (PHP errors, Apache errors).
We have a folder in a classic asp site that has ssl set up for that folder. It works but when you load the first page within the folder and then follow a hyperlink to another page in the folder you get kicked back to the page outside the folder which led into the https stuff.
Repeat the process (follow link on non https page > go to https folder > follow link to other page in https folder) and it all works fine, for a random number of hops between pages in the https folder, then bang, kicked out again.
I have noticed that the session ID changes all the time when hopping between pages in the https folder. Someone said it was due to IE compatabilty mode swapping but I have forced the thing with a header and using IE dev tools (miss you Firebug) I see the mode stays constant. any ideas please?
We had a similar issue with another project last year. #padas is correct. Sessions on http and https are different and the server will have a problem with it. The option we went for was to https the whole site. It makes sense anyway and helps the user gain confidence in what they are browsing.
It sounds like your traversing between http and https and that will change the session id. If your pages are using session id's to track people you will have issues. You are better off dropping a cookie or forcing https.
I had a drupal site on my local wamp server but after having to reformat my computer and reinstalling wamp and all that, Clean URLS is messing up. I made sure my apache had mod_rewrite enabled and after that i just get a 404 error for everything. When i try to login i also get a 404 error. What can i do? I've looked for a while and cant find anything.
I believe it's mod_rewrite that needs to be enabled.
Got it to work. Had to navigate to the login page directly (/?q=user) rather then just using the login block. Then navigated directly to the clean url page (www.mydomain.com/?q=admin/config/search/clean-urls) and disabled them.
My Sitecore Intranet Portal used to work fine, and i haven't done any changes to my site in days, but suddenly when i try to go to my frontpage i will get a blank "Untitled Page" at this location:
"/forms/IntranetLogin.aspx?ReturnUrl=%2fDefault.aspx"
Anyone know what could be causing this?
Can you check if you have presentation information on your home item? Also, do you see this "Default page" right on the page with URL you supplied, or you are redirected to another page?
If you haven't made any changes to your content or Sitecore configuration, was there perhaps a Windows Update that fouled things up? Double check that ASP.NET is properly configured and enabled. What version of IIS are you running on?
The problem was caused by our Intranet not being able to connect to the LDAP database (our database with users). Someone changed the password to the database without telling, we changed it now and it works perfectly.
