I'd never use facebook without this extension.

I have used this extension for years and won't go on Facebook without it. It is, without doubt, the only way to make Facebook palatable in my opinion. I can keep out political posts or racist posts, all with a few keystrokes. A must have for me.

I had given-up on FaceBook because most of my posts were 'sponsored' or 'suggested' or some other FB crap. I couldn't see what my friends were doing. Socialfixer cut-out 95% of the spam. You have to bear in mind that the Zuckers are constantly trying to stop Socialfixer working on FB, so it has to be updated often.
I recently reloaded Firefox, forgetting to reactivate Socialfixer, and was surprised at how much FB shite swamped my site within a day. I would not use FB without Socialfixer.
