It is a fact of life now, It should only be apppearing for sellers who ignored the eBay mandate to remove active content and outside links.
Since it isn't something that will be fixed by eBay, I kludged up a workaround using a bookmarklet that works pretty good for me when my buyer hat is on.The approach has an issue with sizing due to the nature of browser external iframe security (so a compromise using a fixed frame size with scrollbars is used) but works great.
If you still have trouble getting the full description to print when printing an item page (because items you look at have huge descriptions), you can easily increase the frame size in the bookmarklet to suit by editing a single height number in the code right at the end)
Copy/paste the bookmarklet to your browser bookmarks bar, and when an item page with a "See full item description" button appears just click the bookmarklet and the description will appear where it should.
https://community.ebay.com/t5/Selling/See-Full-Item-Description-FireFox-Workaround-Bookmarklet/m-p/2...(There are ways to do this automatically, but require running GreaseMonkey or other browser addons along with a script to address the issue. Since no one else is willing to go to those lengths, and it isn't a huge issue for me, I haven't bothered writing the script)
BTW, blame Google (and soon Firefox and the others) for this. They changed their browsers to throw dire warnings about hackerzez and security for mixed content and forced the issue. eBay's change of adding the button is just damage control in response. If eBay did not, Chrome would throw a dire warning that would confuse and frighten the non-technical.
Anyway, just use the bookmarklet and get on with your buying. Any questions, ask.
