Incredible. I always get a 400 page in Firefox 70.0.1...curl + elinks + chromium 78 works. Must be some SSL ciphers or key exchanges that Mozilla deactivated in Firefox which the server only supports? Because the problem also occurs with a blank profile and no addons...and Qualsys only gives a B mark in the key exchange department.

Well, then things are less wrong than I assumed Always thought the #! forum archive was down completely.

Perhaps eight.bit.al sees the same thing (400 error in Firefox)?

Re: Dead Link

Firefox (400 error).

I was looking for Openbox pipe menu info.

Re: Dead Link

Could reproduce using curl, and probably found the culprit!

Firefox makes the GET request to https://crunchbang.org/forums/index.php with the following headers:

Host: crunchbang.org
User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:70.0) Gecko/20100101 Firefox/70.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en
Accept-Encoding: gzip, deflate, br
Connection: keep-alive
Upgrade-Insecure-Requests: 1
Pragma: no-cache
Cache-Control: no-cache
TE: Trailers
DNT: 1

resulting in a 400.

Invoking curl with the aforementioned headers also yields the 400 error:

cat >headers <<EOF
Host: crunchbang.org
User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:70.0) Gecko/20100101 Firefox/70.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en
Accept-Encoding: gzip, deflate, br
Connection: keep-alive
Upgrade-Insecure-Requests: 1
Pragma: no-cache
Cache-Control: no-cache
TE: Trailers
DNT: 1
EOF
curl -H @headers -I https://crunchbang.org/forums/index.php
HTTP/2 400 
server: nginx/1.10.3
date: Sun, 10 Nov 2019 22:04:30 GMT
content-type: text/html; charset=UTF-8

If you remove the line

TE: Trailers

from the headers file, the request is successful!

curl  -H @headers https://crunchbang.org/forums/index.php -I
HTTP/2 200 
server: nginx/1.10.3

pragma: no-cache
content-encoding: gzip

To get the content with the remaining headers

curl -s  -H @headers https://crunchbang.org/forums/index.php | gunzip

Chromium does NOT send this header (see MDN). So I'm wondering if that's a problem with the specific nginx configuration and/or version that is used. Looking to find some hints or bug reports...still not 100% sure if this is a client or a server problem, though. Will ask around.

The TE header is http2 specific, however crunchbang.org is so far the only HTTP2 site giving me this kind of trouble (and a lot of sites do HTTP2 nowadays).

Re: Dead Link

Would be nice if there was a setting in Firefox to act similar to Chromium in sending headers...that can fix a lot of issues with FF in accessing HTTP2 sites that are broken.
