Two HTTP requests are issued for localhost on refresh in FF4

[Lekensteyn]

OK, I managed to reproduce it.
It seems to happen when Firefox's own DNS cache is empty or invalid and a DNS request is sent out.

I should have fixed in latest development build (RC10), could you confirm?

Stlll affected.

Reproduction steps:
- Create a new folder: mkdir noscript
- Launch Firefox: firefox -no-remote -profile noscript &
- Start HTTP server: python -m SimpleHTTPServer
- Install the developer build from http://noscript.net/getit
- Restart Firefox
- Open: http://localhost:8000/ (1 new request seen in the shell)
- Press Refresh (2 new requests seen in shell)

I noticed something weird, when holding F5, I got a message in the shell from FF:
- [NoScript] Operation is not supported while processing JS redirects
This have nothing to do with this bug, the bug is really related to ABE. Disabling ABE causes the problem to disappear.

It's still not fixed for me either. I still get two requests and a broken pipe on the first request.

Code: Select all

OK, even though I couldn't reproduce anymore, I've removed the only possible cause at its root in latest development build rc14.
Please confirm the fix, if possible.
Thank you.

[Lekensteyn]

I can confirm that the latest development version (2.1.0.6rc14) does not contain the bug.
Tested according my previous post (1) and the Webconsole with Show request/response headers on (2)

Sorry for the delay. I've been out of the office and hadn't had a chance to confirm. It's now working. Thanks for looking into it.
