In a few test cases, we use eval(), new Function. Usage of eval() or new Function() will trigger Assertion in nsScriptSecurityManager. Hence we are adding prefs to these test files for toggling the assertion. Prefs are added for 39 test files, 1. devtools/client/storage/test/browser_storage_cookies_hostOnly.js 2. devtools/server/tests/unit/test_eval-01.js 3. devtools/server/tests/unit/test_eval-02.js 4. devtools/server/tests/unit/test_eval-03.js 5. devtools/server/tests/unit/test_eval-04.js 6. devtools/server/tests/unit/test_eval-05.js 7. devtools/server/tests/unit/test_frameactor-01.js 8. devtools/server/tests/unit/test_frameactor-02.js 9. devtools/server/tests/unit/test_frameactor-03.js 10. devtools/server/tests/unit/test_frameactor-04.js 11. devtools/server/tests/unit/test_frameactor-05.js 12. devtools/server/tests/unit/test_frameactor_wasm-01.js 13. devtools/server/tests/unit/test_framearguments-01.js 14. devtools/server/tests/unit/test_frameclient-01.js 15. devtools/server/tests/unit/test_frameclient-02.js 16. devtools/server/tests/unit/test_functiongrips-01.js 17. devtools/server/tests/unit/test_getyoungestframe.js 18. devtools/server/tests/unit/test_listsources-03.js 19. devtools/server/tests/unit/test_nativewrappers.js 20. devtools/server/tests/unit/test_new_source-02.js 21. devtools/server/tests/unit/test_objectgrips-01.js 22. devtools/server/tests/unit/test_objectgrips-02.js 23. devtools/server/tests/unit/test_objectgrips-03.js 24. devtools/server/tests/unit/test_pauselifetime-01.js 25. devtools/server/tests/unit/test_pauselifetime-02.js 26. devtools/server/tests/unit/test_pauselifetime-03.js 27. devtools/server/tests/unit/test_pauselifetime-04.js 28. devtools/server/tests/unit/test_sourcemaps-03.js 29. devtools/server/tests/unit/test_sourcemaps-17.js 30. devtools/server/tests/unit/test_threadlifetime-01.js 31. devtools/server/tests/unit/test_threadlifetime-02.js 32. devtools/server/tests/unit/test_threadlifetime-03.js 33. devtools/server/tests/unit/test_threadlifetime-04.js 34. devtools/server/tests/unit/test_threadlifetime-05.js 35. devtools/server/tests/unit/test_threadlifetime-06.js 36. js/xpconnect/tests/chrome/test_bug596580.xul 37. js/xpconnect/tests/chrome/test_windowProxyDeadWrapper.html 38. toolkit/components/passwordmgr/test/mochitest/test_autocomplete_sandboxed.html 39. toolkit/components/passwordmgr/test/mochitest/test_autofocus_js.html
