Sometimes when I rapidly open many,many tabs/windows of Firefox these most recent fail to download due to server time-out. This is very good visible on very slow Internet connection (e.g. old 33600 analog modem connection to net) and many FF tabs/windows open. The most recently opened pages will time-out because the network connection bandwidth is filled up with content downloaded by previously opened pages. The smart option for FF is to smart download pages one by one by caching clicked links in memory and opening them only when previous page will end downloading and release net bandwidth. This way pages which are available and working will not time-out just because net connection is congested with download of previously clicked web pages.

Reproducible: Sometimes

Steps to Reproduce:
1. Connect to the Internet using very slow connection.
2. Open many,many,many web pages (in tabs or windows).
3. Keep watching like first pages keep being downloaded and those later opened after some time return time-out instead of content. If you are lucky the last pages which timed out may be partially downloaded and will allow you click 'Refresh' to reload them. If there was long data starvation time there will be no possibility to click 'Refresh' because web page timed out before it began to download.
Actual Results:  
Opening many web pages on slow connection will time-out the last opened.

Expected Results:  
firefox should manage webpages download by making webpage download queue. Thanks to webpage download queue I can read these first downloaded and be sure the rest will not time out.

This is very old unconfirmed bug and might be WFM these days. Honza, is CDP going to help with opening many tabs at once?

Yes, this is definitely related.  Since we are going to narrow the number of outstanding connections down, this will be gone.
