When I reload Fire Fox after a session all of my add-ons have been deleted off, and it acts as if it's my first time running fire fox.

I recently updated Fire Fox and after the update for Fire Fox Portable after each time I end a session and begin a new one it erases all of the add-ons that I have installed unto Fire Fox, and acts as though it is running Fire Fox for the first time.

don't delete your profile, or make a copy and restore it afterwards

drive:\FirefoxPortable\Data\profile


FirefoxPortable has its own forum.

The following page may help you or not, I have not touched the page except for minor updates, nor used Firefox Portable for about five years.


You manage your profile in Firefox Portable the same way that you would manage your Firefox profile. You install extensions the same way as in Firefox. Instructions are supplied at Firefox Portable to copy over the extensions you already use. see http://portableapps.com/support/firefox_portable#local_profile

The main difference is that the profile for Firefox Portable is a lot easier to find.

Do you have that problem with the portable version or with the regular Firefox version?

It is possible that there is a problem with the file(s) that store the extensions registry.
Delete the files extensions.* (extensions.sqlite, extensions.ini, extensions.cache, extensions.rdf) and compatibility.ini in the Firefox profile folder to reset the extensions registry.
New files will be created when required.
