Since late Friday night, an expired certificate caused all add-ons on Firefox to be disabled.
With Adblock Plus being one of the favorite add-ons for users world-wide, this hits us hard. But we have absolute confidence in the open source community behind Firefox to get this fixed as soon as possible!
There is nothing you can or need to do, other than wait for Firefox to update, which will most likely happen automatically.
An ad blocker is a piece of software that can be used to block ads, and they work in two ways. The first way is when an ad blocker blocks the signal from an advertiser’s server, so the ad never shows up on your page. Another way ad blockers work is by blocking out sections of a website that could be ads.
One of the most popular free ad blockers for Firefox. Block annoying ads on sites like Facebook, YouTube and all other websites.
Adblock Plus blocks all annoying ads, and supports websites by not blocking unobtrusive ads by default (configurable).
