Reproducible: Always

Steps to Reproduce:
1. Start Minefield with new profile + several plug-ins
2. Open "Add-ons Manager" (Ctrl+Shift+A)
3. Open "New Tab" (Ctrl+N)
4. Switch "Add-ons Manager" Tab

5. Select "Appearance" , "Extensions" pane
6. Switch "New Tab" tab
7. Switch "Add-ons Manager" Tab and select "Plug-ins" pane

8. repeat step5-7 at least 10 times

9. Try to toggle enable/disable several plug-ins. and Watch Memory usage in TaskManager

10. Repeat step 9 at least 5 times

11. Quit Browser (Alt , F, x)


Actual Results:
*In step 10:
 Memory usage is significantly increased by toggle plug-ins. 
 It takes time to toggle plug-ins. it is performance lag.
*After Step 11:
 Browser crashes with crash reports.

Expected Results:
 Should not increase memory usage.
 Should not encounter performance lag.
