Hi BigAl, you have an interesting problem. I notice your comment:

As I said, it is a persistent problem across, what is now quite a few different versions of FF and on three different computers, three 32 bit and one 64 bit.

So you have a situation that's extremely common in your environment but rare elsewhere. I have access to a number of different machines running El Capitan (MAC), Ubuntu 15.10 and Windows 10. The ME site works with all operating systems and with all the browsers I had time to try (Firefox, Chrome, IE and Dooble). On most of these I use two ad-blockers.
The only similar problem I had was with Firefox on Windows 10 where the black bar was briefly misplaced before reappearing in the correct place. This only happened once but it does hint that there's something odd about the way the bar is rendered.
For security and privacy reasons most of my browsing is done from Ubuntu, mostly using Firefox. I have a good look at the ME site most days and haven't noticed any problems with it.
You might just be unlucky, but I suggest your issue may be due to something in your environment: something that is common to 3 different computers. For example:
- Your ISP may be applying some form of blocking. I think this is unlikely, but…
- Your gateway/router may be applying some form of security. It is worth checking the settings and perhaps trying a factory reset.
- Have you installed an additional firewall or other network devices?
- Is your hardware similar on all three boxes? In particular do the machines have the same graphics card? Not all cards are well supported by linux; some need to be tweaked or have special software loaded.
- Are you using the same video screen on all three machines? Sometimes these are fussy.
- The common factor may be you! Did you install anything in the way of software or browser plugins that might be interfering? Did you use the same installation media? – perhaps it was corrupt. You seem to be computer literate – did you change anything on all three boxes?
Apologies if I missed it but I don't think you've tried a browser other than Firefox yet. They are easy to download and install – Ubuntu software centre lists at least 10. You only need one to work!
Cheers
Dave
