Are you allowing that site to set cookies?

Can you reach the fields with (multiple) presses of the Tab key?

I am not aware about any cookies settings altered from default for this site.

I can click on other things on the home page like different sections of the site - there are U tube clips that I can click on and watch- the tab button is working the same as my cursor- I have noticed I can actually click on to log in button and it responds saying enter your e-mail address but I still can't type anything in the log in box or password box

I have just right clicked the log in / password box and it says "function disabled by Euro Boiler Parts" I will contact them again as previously they told me it was probably my security settings. Still doesn't explain why it works ok with Internet Explorer

OK, I've checked the page and they have some script running that intercepts a mousedown event and that isn't working in Firefox.

function killCopy(e){
return false
}
function reEnable(){
return true
}
document.onselectstart=new Function ("return false")
if (window.sidebar){
document.onmousedown=killCopy
document.onclick=reEnable
}

A bookmarklet with this code as the location will enable you to click in the fields.

javascript:void(document.onmousedown=null);

This code also works in the command line of the Web Console (Web Developer > Web Console;Ctrl+Shift+K).
You can add void(document.onselectstart=null); if you want to bypass the selection disabling.

Thank you Cor-el you seem to have done a lot of work to find out the problem, the response from Euro Boiler Parts was simply use another browser instead of FireFox. If your findings above can be applied to make the fix I would need step by step instructions. Thanks again.

1. Make sure that you have the Bookmarks Toolbar visible: Firefox > Options or View > Toolbars
2. Create a new bookmark on the Bookmarks toolbar via the right-click context menu
3. Copy and paste the full JavaScript code in the location field of that new bookmark:
   javascript:void(document.onmousedown=null);
4. Give that new bookmarks a keyword like "onmousedown disable" (without quotes).

• https://support.mozilla.org/kb/Bookmarks+Toolbar

Open the http://www.euroboilerparts.co.uk page and click the "onmousedown disable" button on the Bookmarks Toolbar to run the JavaScript code.
That should allow you to click the input field and enter the name and password.

You can contact the website and point them to this forum thread, so they can look into this and fix it for Firefox users.

Thanks cor-el it works!! I will contact the website with the thread info.
