Hi craig414,

Losing bookmarks, passwords, and other data after reinstalling Firefox can be frustrating, but there are a few steps you can take to attempt recovery. Here's what you can try:

1. **Firefox Sync:**

  - If you had Firefox Sync enabled before the crash, your bookmarks, passwords, and other data might be recoverable. When you reinstall Firefox, sign in with your Firefox account that you used for Firefox Sync, and it should sync your data back to the browser.

2. **Check for Old Firefox Data:**

  - When you uninstall Firefox, it doesn't always remove your profile data. Before reinstalling, it's a good idea to check if there's an old profile folder on your computer. You can find the profile folder in a directory like:
    ```
    C:\Users\YourUserName\AppData\Roaming\Mozilla\Firefox\Profiles\
    ```
    Look for a folder with a name like "xxxxxxxx.default." If you find it, there may be a chance to recover data from it.

3. **Restore from Backup:**

  - If you have a backup of your Firefox profile, you can restore it to recover your bookmarks, passwords, and other settings. Firefox periodically creates automatic backups of your profile. Look for a folder named "bookmarkbackups" within your profile folder and check if there are any JSON files inside. These are backup files that you can restore.

4. **Third-Party Software:**

  - There are third-party tools designed to recover data from browsers. Tools like "MozBackup" or similar may help you recover bookmarks and other data. Be cautious and ensure that you download such tools from reputable sources.

5. **Check Firefox Installation Folder:**

  - Sometimes, uninstalling Firefox might leave behind some residual files. After uninstalling, check the installation directory (usually in "Program Files") to see if there are any folders related to Firefox. If so, delete them before reinstalling.

6. **Firefox Profile Manager:**

  - Before reinstalling Firefox, you can try creating a new profile or using the Firefox Profile Manager. This may allow you to access your old data. Run the following command in the Run dialog or a terminal:
    ```
    firefox.exe -P
    ```
    This will open the Firefox Profile Manager.

Thanks Regards
