 = Feature Summary =
-This feature focuses on minimizing prefetch usage during firefox startup to improve startup performance of firefox. This is done through detecting that the Firefox PF read and write files on a Windows OS are not 0 KB. When they are detected to be 0 KB, we then write over those Firefox PF prefetch files to minimize the prefetch loading of those files on startup to a 0 KB PF file that is read only. This typically happens on the first startup after 1 minute or during a firefox update from a firefox version that did not support this feature. Once the 0 KB PF file read only specification is set for the Firefox PF files, the 0 KB PF files should remain as O KB PF files that are read only.
+This feature focuses on minimizing prefetch usage during firefox startup to improve startup performance of firefox. This is done through detecting that the Firefox PF read and write files on a Windows OS are not 0 KB. When they are detected to be 0 KB, we then write over those Firefox PF prefetch files to minimize the prefetch loading of those files on startup to a 0 KB PF file that is read only. This happens as a one-time operation on the first startup after 1 minute or during a firefox update from a firefox version that did not support this feature. Once the 0 KB PF file read only specification is set for the Firefox PF files, the 0 KB PF files should remain as O KB PF files that are read only. Additionally, the about:config parameter "app.update.service.prefetchCleared" is set to true, indicating that the prefetch process is finished.
