This sometimes happens for no particular reason.

When you have a problem with one particular site that previously worked normally, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.

(1) Clear Firefox's Cache

See: How to clear the Firefox cache

If you have a large hard drive, this might take a few minutes. If you do not see the number going down on the page, you can reload it using Ctrl+r to check progress.

(2) Remove the site's cookies (save any pending work first). While viewing a page on the site, try either:

• right-click (on Mac Ctrl+click) a blank area of the page and choose View Page Info > Security > "View Cookies"
• (menu bar) Tools > Page Info > Security > "View Cookies"
• click the padlock or "i" icon in the address bar, then the ">" button, then More Information, and finally the "View Cookies" button

In the dialog that opens, the current site should be pre-filled in the search box at the top of the dialog so you can remove that site's cookies individually.

Then try reloading the page. Does that help?

Thank you for the suggestions but still not able to open the www.abr.gov.au website. I need this for work so please help me solve this issue.

Do you have restrictive cookie settings? You can check Firefox's built-in settings using the steps in this article: Websites say cookies are blocked - Unblock them.

Some add-ons may affect cookies. Could you test in Firefox's Safe Mode? In Safe Mode, Firefox temporarily deactivates extensions, hardware acceleration, and some other advanced features to help you assess whether these are causing the problem.

If Firefox is not running: Hold down the Shift key when starting Firefox.

If Firefox is running: You can restart Firefox in Safe Mode using either:

• "3-bar" menu button > "?" button > Restart with Add-ons Disabled
• Help menu > Restart with Add-ons Disabled

and OK the restart.

Both scenarios: A small dialog should appear. Click "Start in Safe Mode" (not Refresh).

Any improvement?

Sorry this didnt work either?

Does it work in IE or Chrome for the time being? I'm out of easy things to try and have to get dinner. :-)

No it doesnt work in IE or chrome either? I just dont know what to do.

Well, hmm. Have you tried rebooting everything -- Windows, router, firewall?

Not sure what you mean by rebooting windows, router and firewall?

For Windows, simply shut down and start up again. For routers, for example, the one that comes with your home internet service, unplug it, wait 15 seconds, then plug it back in again. Some people may have multiple routers or separate firewalls.

I have done all the shut downs and still not

working.

Sorry, I just noticed when I load the site's there's no www:

https://abr.gov.au/

I don't suppose that is the redirect (away from www) that is not working for you?

Yes I've tried that and still didnt work. This morning I can get onto the website, and I want to apply for an ABN I click on the link which goes to another page and I click on the tab thats says,

'Applying for other business registrations

If your application is successful or if you get a reference number you can continue and apply for other business registrations.

Note: If your ABN was recently cancelled by us, you may not need to submit a new application. Call 13 92 26 to see if your ABN can be reinstated over the phone. 'Apply for an ABN' (this is the tab) but still get this error

"The page isn’t redirecting properly

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

   This problem can sometimes be caused by disabling or refusing to accept cookies."

This is so dam frustrating. Any more ideas?

When I click the yellow button, I get a series of redirects that include changing the session cookie, which seems unusual:

First Request

Do you connect through any software that might be fumbling or disallowing the cookie change??

No I do not go through any software. I have firefox as my preferred browser and I have a bookmark I use but have deleted that and go to google search and click on the abr.gov.au link there

Since this is not specific to Firefox, I'm wondering whether external software, for example, like Avast, ESET, or Kaspersky, may be intercepting and filtering your connection. Otherwise, it's hard to understand how the problem could be occurring in all of your browsers.

I dont know either why this is the only ATO website I cant get access to. I dont have any of the software you are mentioning. How would I know if it is external software that would be causing this issue? Now I cant even get to the page where as I was able to this morning????

One possible way to detect an interception would be to check the site's secure certificate. If you launch its home page, you can inspect that as follows, either:

• right-click (on Mac Ctrl+click) a blank area of the page and choose View Page Info > Security > "View Certificate"
• (menu bar) Tools > Page Info > Security > "View Certificate"
• click the padlock or "i" icon in the address bar, then the ">" button, then More Information, and finally the "View Certificate" button

Does the "Issued by" and "Certificate Hierarchy" match the attached screen shot?

Hi Yes it does. Exactly the same as yours. So now what? Boy this is so annoying
