Story Topic:


For FF v32 starting with a new profile from scratch:

FF v32 uses logons.json. Copying over your previous signons.json and key3.db wont't work. Might have something to do with key4.db soon?

1) Get your new profile set up.
2) In about:config, change signon.importedFromSqlite to true.
3) Close Firefox.
4) Copy your signons.json (not key3.db) to your new profile folder.
5) Open Firefox.
6) Your saved passwords should now work.
7) The about:config pref will have to remain true even if you remove your signons.json file.
8 ) Hopefully the logons.json will work in future FF versions without any extra work.

It'll be a good idea to archive your signsons.json and key3.db.

It worked for me. If there's a less painful way to do this, I didn't find it. Cheers!

It's all automatic unless you're manually copying passwords from one instance to another.

Sometimes, the impossible can become possible, if you're awesome!

That's what I meant by "starting with a new profile from scratch" and " Copying over your previous (files)."

Though I have no idea what I meant by "Might Mot Work." Smile

By automatic you mean installing v32 portable "right over" the previous portable install according to your "Upgrading Firefox Portable" instructions in the paragraph beginning "To upgrade to a newer version..." Then on first run v32 will migrate the signons.json data to logons.json? Same for the "built in updater"??

Can one assume the instructions in the paragraph beginning "If you're upgrading from Portable Firefox..." would not work in that it involves "copy your profile from the old ... into the new"?

Yes he meant installing a new version of Firefox Portable 'right over' the old version. The Data directory does not get touched by the installer.

If I remember correctly, copying the whole "profile" folder will automatically handle these kinds of updates as the data migration systems are built into Firefox and it will see what old version you're upgrading from in the profile and handle it accordingly.
And the reason specific files copied from older versions will not necessarily be handled automatically is because Firefox doesn't know you have previous data in the old files for it to parse and rewrite into the new files.

If you try copying an old Portable Firefox's profile into a new install of Firefox Portable you should let us know how it goes for you.

P.S.: Were you typing with your hands full? (jk)
