Google Chrome --allow-file-access-from-files disabled for Chrome Beta 8

Looking at the issues for this shows that the whole --allow-file-access-from-files thing was rushed.

1. "Firefox does it.."
2. "How can we do it?"
3. some time passes
4. "Here are the patches"
5. "Passes! On trunk wonder what happens in the next dev release"
6. "Ahhh it's broken" "Use the command line option" "ok"
7. "We shipped!"
8. "WTF guys? You broke all my stuff! Why didn't you tell us earlier?"
9. silence

On to your Problem
Indeed it seems that this is something special to the beta, I'm using Chrome 8.0.552.5 dev here and --allow-file-access-from-files works like expected, I've also tested this with Chromium 9.0.592.0 (66889) were it also works as expected.

I suspect there have been some changes on the dev branch. Unfortunately, finding something on chromium's issue tracker is nearly impossible.

Did you close all chrome instances before opening with the command line argument? You have to do that to make that parameter work.

To summarize all answers so far.

Before running chrome, make sure there are no chrome processes running.
