Download manager does not start downloading after "save as" dialog is presented. When link is copied to IE it works. It started happening around latest alpha. And still present in beta2. Bug is not limited to any file type. Reproducible: Sometimes Steps to Reproduce: 1. 2. 3.
It seems to be the same symptoms as described in comment #4: https://bugzilla.mozilla.org/show_bug.cgi?id=343320#c4. However not the same as original bug.
Matej: any errors in the Error Console? Also, are you running any extensions at all? Does this still happen in Safe Mode?
It's extremely hard to reproduce it. Only when running firefox for really long time (like one week). Yes I have extensions installed like adblock, rss ticker and adblock. Others are not compatible with 3.0 and are disabled. Will try to reproduce it inside safe mode with clean profile. Maybe there is a problem with old 2.0 profile. And be sure to check error console next time.
This bug seems to be fixed (i believe from Beta4).
