I’ve used AdBlock Plus since 2010 to remove annoying ads and popups from websites I visit. It makes sites load faster. I especially like the ads removed from YouTube videos!
You can download it here – https://www.adblockplus.org/ .
Facebook will detect it and ask you to disable it which you can do by clicking on the ABP stop sign in the upper right of your browser and unchecking “Enabled for this site”. This will only turn it off for the current website.
Note that this will not prevent ad focused malware from being obnoxious. Only a proper cleaning will do that.
So give it a try and browse faster w/o so many ads!
