try these tips -
If Firefox is not showing taskbar icons, you can try these steps:

Check full screen mode
If Firefox is in full screen mode, the taskbar will be hidden. You can use the F11 key to toggle full screen mode on and off.

Check the settings file
The settings file that stores window dimensions might be corrupted. You can try renaming the settings file.
Check taskbar settings
On Windows 10 or Windows 11, you can check which icons appear on the taskbar by going to Settings > Personalization > Taskbar. From there, you can turn icons on or off.

You can also pin Firefox to the taskbar by following these steps:

Click the Windows menu button in the taskbar
Click the arrow next to All Apps
Hover over the app you want to pin
Right-click on it and select Pin to taskbar

or try - Restart Firefox: Close and reopen Firefox to see if the issue resolves. Clear Icon Cache: Delete IconCache. db in C:\Users\YourUsername\AppData\Local and restart your computer. Create New Shortcut: Make a new Firefox shortcut on your desktop, then pin it to the taskbar
