I altered my network.http.max-persistent-connections-per-server setting to 5, yet in download manager, I'm still unable to download more than 2 items (the default setting) simultaniously from one site. Interestingly, this does not happen in regular Mozilla (1.7+). All 5 start up at the same time. Reproducible: Always Steps to Reproduce: Find a page that has a bunch of files you want to download in download manager, like .zip's. 1. Typically what I'll do is pick 5 files or something to download at once. I'll CTRL-CLICK on them so they go into new tabs, so I dont loose my place in the web page waiting for it to respond. 2. I'll have 5 tabs all loading, the first 2 will load and download manager will pop up. The last 3 will continue to churn until one of the items in download manager completes, then the next tab will stop churning and show up in download manager, and so on until they are all done. 3. This happens on several sites, I'm confidant that its not a server imposed 2 similtanious connections limitation.
network.http.max-persistent-connections-per-proxy seems to be ignored, too. It looks like the problem is somewhere in the networking code.
fixed in firefox branch nightlies starting sep 2 (and trunk since aug 3) *** This bug has been marked as a duplicate of 252118 ***
