I am attending college online and regularly have to submit files. When attempting to submit homework, I get the following message: The file which you are trying to upload is empty or cannot be found. Please select a valid file to upload. I have tried .xls and .pdf files with the same error.

I have this error also when I try to upload to the PearsonMyLabandMastering site. I have uploaded files using Firefox extensively up until this week. I cannot say for sure, but I don't believe it happened until after I upgraded to 7.0.

BTW, the files upload just fine with Chrome. I did not check IE.

I have the same problem but I'm using the linux version of firefox and it worked on 6.0.2
