[Note: I've discovered why, now the question is how? See below]

I've noticed in the last few days a number of questions being greyed out, such as the example below. There are no downvotes on them, that I can see.

Is this a bug, or a feature?

I am using Firefox 8.0.

ETA: I just realized that I had the regex tag on my "ignore tag" list, where I sure did not put it. It's always been on my favourite list, and before, questions tagged perl + regex have been red/pink. I've no idea how regex ended up on my ignore list.

I guess this changes my question to: How did "regex" move from my favourite tag list to my ignore tag list? Not sure if I should edit the question more to reflext this.

Those are questions that have tags that you have ignored. They won't appear on your home page, but they will appear in lists of questions (e.g. new questions, tag pages); however, they will be greyed-out to show the presence of an ignored tag.

  • Yes, I just realized that I had regex as an ignored tag. That is very, very odd, because I put it under favorite tags, where it's been for a long, long time.

  • But, why is it not happening in IE then? (For the record, it is working for me in IE 8). Dec 16, 2011 at 9:01
  • @S.L.Barth I was not logged into SO in IE, haven't used IE in months.

  • @S.L.Barth In fact, I was unable to log in... that's odd. Oh well.
