How to open JSONLZ4 file?

The most common problem when using Mozilla Firefox Compressed Bookmark Backup Format is that a specific JSONLZ4 is not associated with the program. Thus, when you open JSONLZ4, the program selection wizard or some other program starts. How to solve such a problem?

The first thing you should do is just "doubleclick" on the JSONLZ4 file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Firefox

The first step is to check if the computer has the Firefox program installed. This can be achieved by typing Firefox into the operating system search engine. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Later in this article you will find a list of programs that can open JSONLZ4 files.

Programs to open JSONLZ4 file

Remember to download programs supporting JSONLZ4 files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Firefox with JSONLZ4 files

However, it may happen that the application itself does not cause the JSONLZ4 file to open in the Firefox application, but you can set it manually. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The window will show, among other things, the type of the file and the information by which the program is used to launch the file. Using the "Change" button we can select the desired program. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. The "always use the selected program ..." field will set the Firefox application as the default for handling the JSONLZ4 file.

Step 3. Update Firefox to the latest version

If, despite the association of the Firefox program with the Mozilla Firefox Compressed Bookmark Backup Format file, the file still does not open, check the program version and possibly update it to the newest version. Some applications allow you to update from the program level, and for others you need to download the installer from the Mozilla Corporation page and install.

Step 4. Check for the following problems with the JSONLZ4 file

Of course, it may happen that despite the above steps, the file still does not work. This could be due to the file itself, the cleanest issues are:

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the JSONLZ4 file. Downloading the file again should fix the problem.
The most common cause here is computer viruses. A virus scan using an up-to-date antivirus program should fix the problem. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file JSONLZ4 or the program directory. Sometimes virus-infected JSONLZ4 files cannot be recovered, so make a backup in advance.
Older version of JSONLZ4 file may not always be supported by the latest software version. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for the failure. The repair method must be adapted to the type of file and damage. Some programs offer the option of recovering data from damaged JSONLZ4 files. You can restore the file from a backup or use help.
The program indicates that the file is encrypted or corrupted. The encrypted JSONLZ4 files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. While there is usually no problem reading such a file, it may not be possible to save it. If possible, you can try to move the JSONLZ4 file to another location.
This problem usually affects more complex files. You may find that another program you are using is preventing you from working with the file. Running programs (including those in the background) should be verified. If the error persists after closing other programs, wait for a while. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If nothing helps, please reset the device.
