Why has my Firefox Sync Key changed and how to access my data now?

I had been using Firefox 3.0 with Sync as browser add-on installed on an old Ubuntu distribution for which the support period has ended. I moved to Linux Mint 13 with Firefox 15.0 recently and I realized that my Firefox Sync Key is not valid anymore.

My Sync account is still active (Firefox accepts my password) and my key is correct for sure (I have two equals copies of it -- in a text file and on an html document auto-generated by Firefox after generating my key for the first time).

I found out that the key format was changed between these two versions of Firefox. My current key comprises four dash-separated quintuples of characters. A new key, proposed by Firefox, contains a single digit, followed by a dash and five such strings.

How can I access my Sync data with my old, correct key, which is no longer accepted or how to calculate a new key while having the old one?

Try to remove all hyphens in the sync key and enter the string as one long line of 26 characters when you set up sync.

But this is the crux of the problem -- my sync key has 20 characters, not 26!

It has the format: ccccc-ccccc-ccccc-ccccc ("four dash-separated quintuples of characters");

While the currently accepted format is: d-ccccc-ccccc-ccccc-ccccc-ccccc ("a single digit, followed by a dash and five such strings").

This is why I titled my question "Why has my Firefox Sync Key changed..." -- my sync key is no longer a valid key. I have already tried several default-looking prefixes and suffixes to extend it to 26 characters but it is not as easy.
