I do not understand anything but the most basic HTML & CSS but if you are saying something does not render or function in Firefox on Ubuntu can you give a reduced test case example.

I can compare that in Ubuntu 12 and in Windows 7 Firefox.

BTW When I try in Google Chrome on Ubuntu 12 your tables line up but it is a 404 page with no flash content

So far as I have been able to determine, the problem only exists on the home page, no other page of my website. The home page is unique with its dimensions and other attributes, so therefore has its own CSS file. However, it is no different from the CSS of the other pages (other than the dimensions) as far as how the pages are laid out. So apparently the method used to lay out the page is OK, even in Ubuntu 12 Firefox 29, but the home page is somehow different when rendered. Very puzzling.

Finally got the answer to this problem! Javierrivera over on the Ubuntu Forum figured it out in a minute. I had the size of the Input Text box in the search form at the bottom of the page too large. Once I corrected that, Even Ubuntu Firefox works perfectly. Thanks to everyone for giving it some thought!

Glad you found a solution from ubuntuforums

Is also pretty good on the webdesign problems.

John99, I was uncertain this was a web design problem, since it only showed up in Ubuntu/Firefox combo. Nothing else had a problem. However, I should have realized it was a web design problem. I had a similar problem with my feedback page on Ubuntu/Firefox too, which had to do with input boxes again. But the search form (being at the bottom of the page) was out of my focus you might say. :/ I think next time I will assume it is a web design problem.. But I really appreciate everyone's help. It's such a relief to have that sort of knotty problem (abeit a simple one as it turns out) off my desk!

Another contributing factor, was that the search box code came from a third party, and I had no reason to suspect it. But that was again my own fault, since I never did check it thoroughly on all the possible web browsers and OSs after installing it. It wasn't until I installed an Ubuntu system on my old Dell that it came to my attention. Then I started digging and found it only happened on Ubuntu Firefox, and only recent editions too, as my old desktop runs an older Ubuntu (10.04 LTS) which did NOT have the problem.

As javierrivera stated, it is a function of the default character set in Ubuntu, which is apparently pretty large, and which CSS uses as its unit measure in the case where "size" is used and no other font is specified. Live and learn..

Hey I am not complaining, the problem was solved which was the important thing, and as you said it was hard to reproduce and apparently only on certain browsers. I am glad you posted back to let us know the problem had been resolved.

Did you try the Inspector console (Ctrl + Shift + K) and notice the tab options to display

Yes, I did use the Inspector Console. That is a FANTASTIC tool for web designers!
