Gmail attachment failed. This may be due to a proxy or firewall

Hi,

I am getting this error when trying to upload multiple files on gmail and then I have to upload them one by one.

I do not use proxy
I have standard security setting on Firefox
I reinstalled Firefox and flash player

What can be causing it?

Ah...despite the 20mb limit on attachments, its not feasible for more than a few mb at a time, especially if the recieving server doesn't support it.

That is not it. I get this error even if I try to upload very small images.

P.S. it is 25MB now
