Here's an odd one, probably not a Linux issue but I am using Mint + Firefox and I guess the site is on LAMP so it's Linux-ish...
I'm trying to buy some hardware from https://www.ironmongerydirect.co.uk https://www.ironmongerydirect.co.uk
There was >£50 of bits in the basket and I went to Checkout. The site asked me to log in or register, so I registered. Firefox gave me a random secure password to use and saved it for me. So far, so normal. Now I'm back at the home page with the total still showing in my basket. But the 'My Basket' button doesn't work. Neither does Contact or 'Hi Phil' (My Account on sensible sites!) I'm sure you all now that on FF hovering over a link shows the real destination. Hovering over these buttons shows the link is to the current page. I can use the main menu to choose other pages in the catalogue but those three buttons always link to the current page. So all they do is refresh the page. This means not only can I not return to the checkout, I can't even logout via 'Hi Phil'
I've tried closing all the pages then starting again, but FF helpfully remembers the password and logs me in again, with the same issue. I even deleted the saved login from FF, but I still get logged in automatically.
Is there some magic way to log out of a disfunctional site?
