What is a .JSONLZ4 file?
A .JSONLZ4 file is a type of compressed file used by Mozilla Firefox, which is a web browser available for free and can be used on different types of computers and devices. This file contains important data related to a user's Firefox profile, including settings like bookmarks, the home page setup, the layout of toolbars, and saved passwords. The data in these files is compressed using a method called LZ4, which helps make the file smaller and saves space.
To open a .JSONLZ4 file, you generally need to use Mozilla Firefox. This is because the file contains specific user profile data that Firefox understands and uses. There are also specialized tools like Firefox Bookmark Backup Reader/Decompressor that can open these files, particularly for viewing or recovering bookmark data.
.JSONLZ4 files are typically found in the Profiles directory of Firefox's installation folder. This directory is located in different places depending on your operating system: - On Windows, you can find it by opening Firefox, clicking the Menu icon (three horizontal lines), selecting 'Help', then 'Troubleshooting Information'. Here, click the 'Open Folder' button next to 'Profile Folder' under 'Application Basics'. The typical path is `C:\Users\[username]\AppData\Roaming\Mozilla\Firefox\Profiles\`. - On macOS, follow a similar process: open Firefox, go to 'Help', then 'Troubleshooting Information', and click 'Show in Finder' next to 'Profile Folder'. The typical path is `/Users/[username]/Library/Application Support/Firefox/Profiles/`.
Within the Firefox Profiles directory, .JSONLZ4 files are stored in subdirectories like `bookmarkbackups` and `datareporting/archived`. The `bookmarkbackups` folder contains .JSONLZ4 files specifically for backing up bookmarks. These files are named based on the date they were created, making it easier to identify when the backup was made.
If you have many .JSONLZ4 files and they are taking up too much space, you can delete them, but be aware that this will result in the loss of the data they contain, including any user profile information or bookmark backups.
