Can't Connect to internet when uploading in separate tab
I have been using Firefox for many months now for my job. My job requires me to upload videos, documents to a company portal and I have to use multiple browsing tabs to do various task. This week, I noticed that when I am using 1 tab to upload video or any documents, when I try to start another tab, the video upload process shuts down all internet connection until upload is complete. I can not connect using other tabs or other browsers.
I tested it with my ISP using IE and there is no issues. It is strictly a Firefox issue. I really like using Firefox browser when working because it is easier. Can anyone offer a solution for this problem. I have deleted cookies and cache, reinstalled Firefox. Could it be a recent update? Thank you everyone.

Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All of them.
Start Firefox in Safe Mode {web link} While you are in safe mode;
Type about:preferences#advanced<Enter> in the address bar.
Under Advanced, Select General. Look for and turn off Use Hardware Acceleration.
Poke around safe web sites. Are there any problems?
Then restart.
No changes. Still same issue.
