If you have an update to an extension, a change to the settings, or an about:config modification make a mess of your regular Firefox install, then you always have “Safe Mode” to fall back on to help fix the problem.
But what about portable installs? If your portable install becomes a mess you usually just have to replace it. This shortcut modification will give you back that “Safe Mode” goodness and let you work on fixing (and saving) your portable install.
Note: This shortcut modification performed on the Portable Firefox installs from portableapps.com.
Getting Started
The first thing that you will need to do is make a new copy of your current Portable Firefox shortcut. Once you have made a copy (on the Desktop or other location until you finish modifying it), right click on the shortcut and select “Properties”. Once you have selected that, you will see the “Properties” window with the “Shortcut” tab displayed. Now you are ready to modify the “Target Path”.
In the address area for “Target:” you will need to add the following “command” to the end of the target path making certain to leave a single space in between the final quote mark and the “command”.
So the “Target Path” should look like this:
Click “Apply” to finish this part of the shortcut modification.
Next you will need to click on the “General Tab” so that you can add “(Safe Mode)” or other appropriate text to the end of your shortcut’s name to help identify it in your “Start Menu”. Once you have that finished click “OK”. All that you need to do now is add your new “Safe Mode” shortcut to the desired location in your “Start Menu”.
Now you will be able to have access to that wonderful little “Firefox Safe Mode Window” whenever you need it.
Conclusion
If you have been wanting access to “Safe Mode” for your portable Firefox installs when something goes wrong then this is just the solution that you have been waiting for.
