User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041111 Firefox/1.0 (Debian package 1.0-2) Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041111 Firefox/1.0 (Debian package 1.0-2) When attempting to load a new page, if there are any problems with DNS resolution, Firefox hangs until the query times out or provides an answer. (I have had problems with http://edith.freelinuxhost.com/ and the ads on http://www.sweetcollect.co.uk but currently they are working fine because they are not having DNS problems - it is only when a site can't be resolved or takes an unusually long time to resolve that there are noticable hangs.) Reproducible: Sometimes Steps to Reproduce: 1. Find a website which has flaky DNS (not just one that doesn't exist, they fail quite happily - one that does exist or did recently exist but is currently not resolving through nslookup, although Firefox can sometimes find it anyway as it seems to have a longer timeout) 2. Type in the URL or click on a link to said website. 3. Watch Firefox become unresponsive for up to a minute. Actual Results: Firefox did not respond (window did not update properly, leaving other windows on top, clearing completely to window background when minimised and maximised, sometimes leaving mouse trails when cursors were animated ones) for 5-60 seconds. Often after that time the requested page loaded just fine - Firefox had successfully managed the DNS resolution, when nslookup often just timed out instead. Expected Results: Firefox should have stayed responsive whilst doing the DNS lookup in the background. I am using a PAC file and can supply details of it if needed (there are some other bugs about DNS resolution with PAC files, but they are all against older versions and appear to be abandoned for reasons specifically to do with those versions).
I'm having the same problem. I too am behind a proxy. Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0
I have experienced similar behavior when a link opens in a new window. I get stuck on the new, blank, window until DNS resolves (after which I can switch to other windows while the page loads). I am on Windows NT4. This also seems similar to older bug 237582. Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0
