Load a page with a plugin then run htop, you may see a few plugin-container |
| 5 |
child processes for firefox, note it's pid and then run (as root): |
| 6 |
|
| 7 |
cat /proc/<pid>/maps | grep libxul.so |
| 8 |
|
| 9 |
You'll see something like this: |

7ff264f9b000-7ff269e4b000 r-xp 00000000 08:06 8736977 |
| 11 |
/usr/lib64/firefox/libxul.so |
| 12 |
7ff269e4b000-7ff26a04a000 ---p 04eb0000 08:06 8736977 |

When firefox starts the plugin-container process it may just set the |
| 23 |
LD_LIBRARY_PATH environment variable for it, just like the script from the |
| 24 |
binary packages do, or it may do something more complicated. You'll have to |
| 25 |
look at the code to find out. |
