Public bug reported:
Binary package hint: firefox-3.5
After upgrade to 9.10 and firefox 3.5, I noticed that on the some pages,
the firefox would be freezed for a while(tens of seconds), then continue
to work. At first I don't know what cause this, and suspect website's
js. But at one time when freezing, firefox told me:
>A script on this page may be busy, or it may have stopped responding. You can
>stop the script now, or you can continue to see >if the script will complete.
>
>Script: file:///usr/lib/xulrunner-1.9.1.4/components/nsProxyAutoConfig.js:133
Then I know the reason. I am using autoproxy script in the company, then
I tried one certain proxy and it work. So seems the following function
is the root cause(I don't have this problem when using firefox 3.0):
129 // wrapper for resolving hostnames called by PAC file
130 function dnsResolve(host) {
131 host = XPCSafeJSObjectWrapper(host);
132 try {
133 return dns.resolve(host, 0).getNextAddrAsString();
134 } catch (e) {
135 return null;
136 }
137 }
So I believe there is some reasons that dns.resolve() didn't return
quickly. But seems not due to my proxy server.
Thanks in advance to look into this.
