I'm new to Ubuntu therefore I don't know if this issue is already resolved or not. I'm unable to upload any file in any browser. When I did speed test with okla downloading is 10 Mbps but uploading is not working.

I did some research and found this: Unable to upload files with any browser on Ubuntu 14.04, why?

Therefore I need to change my kernel. Is it?

Thanks for the help.

  • No router or isp problem, I am using wifi. For other devices it's running very well. Even for Ubuntu youtube streaming and downloading is very fast. Thanks – Utkarsh Dubey Sep 21 '18 at 23:11
  • I tried testing in a VM if Firefox would have this problem if /tmp was missing or had invalid permissions but it didn't seem to cause any problems. – Kristopher Ives Sep 25 '18 at 15:43
  • Therefore I need to update permission in /tmp, is that? – Utkarsh Dubey Sep 25 '18 at 15:52
  • I wasn't able to reproduce the issue so I don't think /tmp is the problem. I am simply putting that information here for anyone else wondering if that was the problem. – Kristopher Ives Sep 25 '18 at 15:58
  • What you can try doing is closing Firefox, opening your home directory, show hidden files and rename your `.mozilla` directory to something else like `not.mozilla` then launch Firefox and see if the issue persists. Assuming it still happens you can restore your original Firefox settings by renaming the `not.mozilla` folder back to `.mozilla` – Kristopher Ives Sep 25 '18 at 16:01
  • It's appearing in all browser therefore I need to do it for all manually? – Utkarsh Dubey Sep 25 '18 at 16:38
