#5357 closed defect (invalid)

storage.js is wrongly written

FF 55.0b5 (32-bit)

How to reproduce

  1. backup the filters ==> (easylist, private list, other disabled lists - easyprivacy, annoyances, social list etc)

it will result a total of 7 mega backup

  1. close FF, delete storage.js
  1. open FF, restore from backup. Initially storage.js is 7 mega, after normal navigation (2-3 pages), is already 15 mega.
  1. Next day: already 30 mega. ... Today is 45 mega.

I opened the file (in notepad++) and I found out (for example) easylist is written 6-7 times !
I searched for "&ad.vid=","&ad_box_" ==> I found 6 occorrences !

The same behaviour in ABP webext in Firefox (probably the storage.js is managed in the core)

  • Resolution set to invalid
  • Sensitive unset
  • Status changed from new to closed

This is actually the expected behavior. storage.js isn't merely replacing patterns.ini but also the automated backups. So as you are using Adblock Plus, you will get five copies of the data there. See also

Well, 5 backups is too much, until FF will provide some other (intelligent) modality to store the data you should keep only 1 backup. Otherwise you'll see thousands complains about the lag ABP brings in FF.

well, it seems pretty simple, changing the default value here:

I don't know for what reason and without any warning my FF crashed resulting in losing my filters. The storage.js is rewrited to an empty file with a size of 2KB.
With the old automated backups I always had 5 chances to recover my data but with the new modality of data storage, ABP is swimming counter-current.

I will completely disable the backups and try to script something to backups in a separated file(s).

Yes, the automatic backups functionality is no longer meaningful and has been disabled in Adblock Plus 3.0 (to be released soon). Your best chance is backing up storage.js yourself, it isn't something that the extension can do any more.
