The latest Firefox version broke ChatGPT website

Unfortunate; This morning my firefox profile didn't start up, draws the empty window, and spins the CPU. I started my workday with downgrading FF and restoring my previous profile from a backup.

Now this.

FWIF, for this particular problem, the workaround from the linked reddit post works:

Edit 3: This workaround seems to fix it:

    type about:config in the URL bar
    search for network.http.accept-encoding.secure
    replace gzip, deflate, br, zstd with gzip, deflate, zstd

In about:config set network.http.dictionaries.enable to false to fix it.

Two days and still no update for users, it's a shame at that level (of product scale) !

Some request errors relate to "NS_INVALID_CONTENT_ENCODING". In such requests that is set to Content-Encoding: br

Did the new firefox break the Brotli encoding?

I didn't update FF and have the same problem. I think it was the other way around.

I'm glad I'm not the only one with this problem!
