i have a problem for a long time in Firefox and that is whenever i try to upload any file via Elance.com it gives a error and if i click on "Attach file" button it would pop up another page to upload manually.

Error: "Using one of the supported browsers with the latest Adobe Flash is required to experience enhanced file uploading features. Click "attach files" to proceed with the basic version."

I am Using Firefox 34 and latest flyer player installed. On the other hand i can upload any file successfully without any problem on Opera and Chrome.

Any help would be appreciated.

Thanks in advance, Sattar

Do you mean via, or to Elance?

Can you provide a screen shot of the error message itself?

Poke around safe web sites. Are there any problems?

Then restart.
