after a firefox update, I noticed that the icon in the task bar had disappeared. I tried opening from the start in windows 10, so I uninstalled and reinstalled multiple times, however nothing seems to work there is an old desktop shortcut that indicates "windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item. please advise

Please consider turning on send info to Mozilla before posting a question. This helps us help you. You should have supplied the version you were installed or updated to. Of course do not have a Firefox to turn on. Let's see if can help you. Please go to Uninstall Firefox if not already done so. Then go to C:\Program Files and delete the Mozilla Folder and the same in the C:\Program Files(X86) folder.

Now please use Windows Disk Cleanup and clean up all files/folders/temp then run it again and click Clean System Files.

I suggest doing this to correct any Win 10 Registry issues that maybe effecting the reinstall.

Repair System Registry and Files

(FOR DOING Above & Below - WINDOWS All OTHER VERSIONS - Use Search To Find Command Prompt ** Enter CMD.exe to Find COMMAND PROMPT Then Right Click & RUN AS ADMIN)

To run the SFC command use the Windows key + X keyboard shortcut to open the Power User menu and select Command Prompt (Admin). Type "SFC /SCANNOW" (without quotes or copy/paste) and press Enter. For more information on using SFC, please refer to the Microsoft KB: Use the System File Checker tool to repair missing or corrupted system files

Run the Windows Deployment Image Servicing and Management (DISM) and System File Checker (SFC) tools as Administrator. The DISM and SFC tools scan the integrity of the Windows image and all protected system files replaces corrupted, damaged and incorrect versions. (FOR DOING Above & Below - WINDOWS All OTHER VERSIONS - Use Search To Find Command Prompt ** Enter CMD.exe to Find COMMAND PROMPT Then Right Click & RUN AS ADMIN) Type "DISM /Online /Cleanup-Image /RestoreHealth" (without quotes or copy/paste) and press Enter.

Windows 10 To run the DISM command use the Windows key + X keyboard shortcut to open the Power User menu, then select Command Prompt (Admin). Type "DISM /Online /Cleanup-Image /RestoreHealth" (without quotes or copy/paste) and press Enter. While running DISM you may notice the process will appear to pause at 20%. After a few minutes the operation will continue.

Note : SFC fixes files locally using files found on your system. Note : DISM goes up to Microsoft for new ones.

Now please download the Full Version Install for current version 56.0.2 https://www.mozilla.org/firefox/all/

If still issues installing there could possibly be a malware issue prevent the install. https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-caused-malware and https://www.malwarebytes.com/adwcleaner/ and https://forums.malwarebytes.com/topic/9573-im-infected-what-do-i-do-now/
