Starting a download freezes browser window ([Not Responding]) until DL-mgr window appears
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040626 Firefox/0.9.1 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040626 Firefox/0.9.1 When starting a download by clicking on a link, Firefox becomes unresponsive for several seconds (approx. 10) until Download Manager is displayed and indicates download is in progress. During the browser window freeze, Window decorations are painted (border + minimize/restore/close buttons) but inner window remains empty. CPU is pegged at 100%; Firefox consumes all CPU. Hardware: multiple laptops; Intel PIII 1GHz and Mobile AMD Athlon 4 1600+; 256MB RAM each. Issue occurs with and without proxy. Reproducible: Always Steps to Reproduce: 1. Start download of a file, e.g. an ISO file from linuxiso.org 2. 3. Actual Results: Browser window freezes, while the download (DL Manager) is apparently being started in the background. Download Manager window does not appear for several seconds, possibly waiting until data is actually being received. CPU, meanwhile, stays pegged at 100%. When trying to switch to another window, XP considers application "[Not Responding]". Download Manager starts responding after a while (perhaps as soon as data is being received?); this "unfreezes" the browser. Expected Results: Browser windows should remain usable. Download should start smoothly in the background. Firefox 0.9.1 with "fix" XPI from release notes installed. Patch does not appear to solve the issue. I'm initially classifying this as "critical" since from the user experience, the application hangs. However, it does recover if you are patient...
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7) Gecko/20040707 Firefox/0.9.2 Hardware: PIV 2.8, 512MB ram and a 10MBit connection. I've been unable to reproduce this bug. Clicking on any of the different files I tried on linuxiso.org added no more then 6% CPU load even when it needed several seconds to get contact with the server. I run no proxy, firewall or anything active. A guess for this bug could be that it only happens between the moment Firefox actually gets contact with the server and starts a download until it got enough info to pop-up the dialog, and would only appear when trying to download over a slow connection (or from a over loaded server).
Oops, I forgot to add my environment specs: - Asus P4C 800E DeLuxe - P4, 3GHz HT, 800MHz FSB, 2 x 512MB RAM - 2Mbps ADSL - Firefox 0.9.1 - WinXP Pro SP1a with all updates applied. I've reproduced it just now using http://www.linuxiso.org/download.php/350/valhalla-i386-disc2.iso New observation: firefox.exe memory use grows rapidly while browser "hangs". I checked this using Windows Task Manager. - Firefox memory use idles around 20MB. - Open www.linuxiso.org: grows slowly to approx. 22MB - Choose RedHat: no noticeable effect - Click "disc 2" link: rapid growth to to 35 - 43MB; browser "hangs" Hope this helps, Greetings, Ed.

I'm on a Dell 4400 2GHz, 1G RAM, cable connection, running XP home. ***This problem only occurs with Acrobat PDF documents on my system*** In firefox 1.0 (newly installed), the browser has a LOT of problems with PDF files in the following ways: 1. 100% of the time it freezes the browser after clicking on a PDF link; I used to wait for it to unfreeze itself but grew tired of that after I finally installed 1.0 over my old 0.9 firefox and the problem persisted. 2. The only exception to #1 seems to occur if I had previously used Acrobat externally to the browser before i clikced a PDF link. (Strangely, the Firefox plugin settings point to acroread32 to read PDF links, but still loads up my full-on Acrobat Professional 6.0 app every time--what's up with this???). 3. The problem with #2 is that when you exit acrobat (professional, in this case) it freezes the browser anyway. 4. Sometimes the PDF file opens in its own window and leaves an empty browser window open upon closing it (after opening the link with "open in new window). In any case this problem with PDFs is REALLY irritating because it forces me to shut down the entire browser and restart to get control back.
I can verify that this problem exists with Windows XP SP2 and Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0 Whenever I try to start a download, the download window opens and then Firefox freezes. It doesn't matter what I'm trying to download. I don't have a download history, as I have it set to clear history on a successful download. I did not experience this problem with versions of Firefox prior to 1.0. This is a serious annoyance, so I'll probably go back to RC1.
As a follow up to my previous comment. The downloads have magically started working. I didn't change anything, although I did check the download history settings. I don't understand this as Firefox has been freezing anytime I attempt to download since I upgraded to 1.0.
Bugs 270312, 255325, and 261079 appear to be related to this bug. This is cvs build of firefox (initially noticed since the 1.0 release, did not occur in the .9 releases that I remember), win xp, I have an ATI graphics card and am on a laptop. I get two symptons 1) 100% or near 100% CPU utilization, that sometimes is only a brief spike. 2) However, frequently the entire browser will freeze indefinitely and will have to be killed. I can reliably reproduce this bug by initiating 7 or 8 large downloads simultaneously (large as in 20 mb). Usually I right click and do save as. Ie initiate download of all of the links in the demos at this link. http://www.alias.com/eng/products-services/motionbuilder/index.shtml Possibly related is that there appears to be a hard disk access caused whenever a new download is initiated.
This is not an isolated problem. Occurs on 4 seperate computers that I use..WinXP, Win2K & Win98SE. The larger the file to be downloaded the longer FF appears to hang. It freezes longer the first time a file downloaded and the download manager window is not present. But FF will still appear to freeze with each following download. After the download has started or finished FF returns to normal and Windows no longer lists it as "Not Responding". Very annoying for a fast browser to have a snail download manager. Longest time for FF to recover from a download was over 10 minutes while downloading a 15 MB file from someones iDrive website.
always a repeatable phenomon, never a successful download, also trying to manipulate dowload manager under preferences cause the same freeze, both procedures cause a 100% spike in cpu usage. This build Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.8b) Gecko/20050126 Firefox/1.0+ is responsible Machine is 800 mhz thunderbird running win2k over 298 mhz of ram. Firefox works well on the xp machine, which is the only reason I have gone through the trouble of reporting this. Since this is a major dissapointment as far as browser reliability.
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2) Gecko/20050322 Firefox/1.0+ Trying to confirm in latest nightly on my laptop, my relevant environment specs are: 2.0GHz Pentium 4 Mobile 512MB of RAM Windows XP Pro Corporate Service Pack 1 Build 2600 with all updates I decided to try and grab the Knoppix 3.6 ISO for the purpose of this test. http://www.linuxiso.org/download.php/327/KNOPPIX_V3.6-2004-08-16-EN.iso I noticed no hang before the download dialog appeared. No sudden increases in system resources according to the Task Manager.
On second glance, this looks like it may be related to the download history bug. Reporter, Commentors: What is the state of your download history when you reproduce this?
it just starts and then freezes ... I uninstalled Firefox since then so I can't say anymore
Mozilla Firefox keeps telling me I need a critical update, but freezes immediately when I OK it - neither the cancel button or anything will work except to close the update GUI by clicking at the upper right corner. I even turned off my Windows firewall but no better that way.
I found that clicking the Clean Up button in the download manager reduces if not eliminates the freezing. Appears that the manager can't manage that many downloads. I notice a considerable slow down after 10 files are in the download manager queue.
I have the same problem with version 1.0.3 firefox. I believe it is when I have had about twenty tabs loaded in two or three windows, and I have possibly closed some of them. Strangely, the title bar will still get focus and drag the window. Maybe the CPU priority. xp home, sp2, autoupdate. TTFN
