firefox crashed and reloaded and I lost all of my blocked sites

Environment

windows vista home premium
firefox 29.0.1
adblock plus.

How to reproduce

Firefox crashed and reloaded and I had to add ABP again. Of cause I lost all the sites I had blocked. Firefox did leave an "old firefox data" folder on my desktop. Are my existing blocked sites stored somewhere in this folder. How do I restore them?

If Firefox crashed and wiped your whole profile then it's not really an ABP issue.

Try that to recover your old custom filters :

1. Go to Adblock Plus preferences (Ctrl+Maj+F)
2. Click the "Backup and restore" at the bottom-left and then "Restore own backup" (shortcut is Ctrl+I)
3. Navigate to "old firefox data"\Profiles\(your profile)\adblockplus\
4. Select "patterns.ini"

If that doesn't work (for example the size of patterns.ini is too small), try with one of the patterns-backupXXX.ini

For the future, you can use Firefox Sync (ABP can sync its preferences and filters using that) :

As Crits said, this is not an ABP bug. Nevertheless, his approach should work, if the patterns.ini was not corrupted.
