Adblock reinstalls each time I open Firefox

[rasouza]

Recently, each time I open Firefox, a new tab opens saying "Installation Successful!". It contains this message: "It seems that an issue caused all filters to be removed and we were unable to restore a backup. Therefore we had to reset your filters and Acceptable Ads settings. Please check your filter lists and Acceptable Ads settings in the Adblock Plus options." And then each time I open a page that I previously whitelisted, I have to disable Adblocker again. Is there anything I can do to fix this? Thanks.
