On a old machine (512 MB RAM) I am currently running ubuntu jaunty and firefox 3.0.15. I tried the ad blocker addon add block plus but it eats lots of RAM (>300 MB).

  • Is high memory load of this add-on a bug, which is fixed in a newer version or just normal? If so, why is the memory usage so high?

  • Is there another ad blocker add-on for firefox, another browser- add-on combination for linux (ubuntu jaunty) or even better a browser independent solution for linux which uses significant less RAM?

ABP acknowledges on their forum that they have a significant memory overhead, so if you want to get your RAM usage down you will have to switch to something else.

You could always try an ad-blocking HOSTS file, which wouldn't waste RAM. This particular one is regularly updated, but be sure to check it over before adopting it and make a backup of your original to be safe, of course. Lifehacker also has a whole article on this subject.

Can you provide a reference/link for the acknowledgement made by the ABP folks? – Ƭᴇcʜιᴇ007 Jun 16 '12 at 16:37
Further looking into the ABP forums shows a lot of performance optimization threads where IT-savvy folk have got their memory consumption cut down quite a bit. There is a lot of talk about this, the best "acknowledgment" I can find is here:… – Paul Jun 16 '12 at 17:49
@techie007 You can also look into the mercurial logs to see the comments on what the Dev has recently changed and updated. So I recommend everyone makes sure they have an up-to-date plugin to get these fixes in too. – Paul Jun 16 '12 at 17:50

On can also use privoxy or Bfilter. For privoxy there is a script which converts adblock+ lists for privoxy, see:, same for Bfilter:

This method can be applied in modified router firmware such as DD-WRT, but could adding many of those slow down the router? – superuser Jun 16 '12 at 17:31
