Webpage formatting Rated 3 out of 5 stars

I like this theme. But with each update of FF the webpage format seems to get more and more messed up. It finally got so bad that it is almost unreadable. In my attempts to find the problem I discovered that most of it cleared up when I changed from this theme. I don't know why but it fixed it so I can't use this one anymore. Maybe it's just interreaction with other addons but I turned them all off and still had the problem. Changing from this theme is the only solution I can find. I hope someone that knows more than me about it can fix it so I can resume using it.

Update: I think the problem is being caused by something other than this theme. Some pages are still messed up, just not as badly. eBay listings in grid mode were badly messed up and still are with other theme but not as badly. The addons tab itself used to have half of the search bar and half of the last addon listed cut off, with other theme it displays correctly. The pages at instructables.com are still not displaying correctly. I think the ones that improved was just because of some interaction between this theme and something else. So far it is looking like a FF problem. I don't see this problem with IE, but I don't like IE so I only use it when absolutely necessary. Maybe I'll figure out where the problem lies when I find the time to go through all the addons I use more thoroughly.

Apparently, I was in too much of a hurry to place blame before.

This review is for a previous version of the add-on (1.14).  This user has other reviews of this add-on.

It's the first time I hear my theme messes web pages. Please can you give me a link of such a page?
