400 Bad Header; Request Header Or Cookie Too Large
I have a web sites, www.canadiantire.ca, that worked up to the latest updates. Opens home page; select search and enter any search term; hit Return/Enter and get "400 Bad Header", "Request Header Or Cookie Too Large"
Why am I getting this? Canadian Tire says that there web site is developed for Google Chrome (which I an not in favour of switching to)

Hi Peter, do you want to try clearing any cookies Firefox has saved for that site to see whether it helps? Here's how:
While viewing a page on the site, click the lock icon at the left end of the address bar. After a moment, a "Clear Cookies and Site Data" button should appear at the bottom. Go ahead and click that.
In the dialog that opens, you will see one or more matches to the current address so you can remove the site's cookies individually without affecting other sites.
Then try searching again. Any improvement?

Thanks. Removing the cookies worked. Could only do 1 at a time with your method. Faster solution: Preferences/Cookies and Site Data/Manage Data/Search for all cookies related to site; Remove Selected (helps to clear cached web content while you are there)
