With release 21 of Mozilla (as milestone mention), cache path changed in Linux (unix-like) disributions:

• Firefox: ~/.mozilla/firefox/ → ~/.cache/mozilla/firefox/
• Thunderbird: ~/.thunderbird/ → ~/.cache/thunderbird/

The bug report which brought the change:

This is a question in Ask Ubuntu shows the case with Ubuntu Tweak with quick solution which may help:
