I encounter the same problem, so what i did is, on my desktop using firefox right click on the deb file link and select 'save link as' and saved that file to my desktop, and emailed myself that file. opened the same email in my tablet and saved the file in my tablet. and using application manager i installed that deb file. hahahahah.... yeah its a long process but for this situation it is only a 2min job for me.
