Mozilla hangs for some considerable time on page load - maybe caused by advertising?
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7) Gecko/20040514 Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7) Gecko/20040514 Often, (about once per day), I find that Mozilla hangs when loading a page. It will give all the appearances of having crashed, and may take 30 seconds to begin to respond. During this time, I cannot view content in other tabs nor mail. This lack of responsiveness does not happen in most cases of pages being slow to load; only in some specific cases, and these are not usually repeatable. My guess is that it is the embedded adverts, randomly selected, and served by other servers which cause the problem - these are sometimes very slow to load. Adblock does seem to help. It seems that there is one particular moment during an http transaction where, if the remote end stalls/fails, the entire mozilla browser appears to lock up until the expected packet eventually arrives. This can take a long time. Sorry this is so vague - it's a real problem, but is very hard to track down a test case. Reproducible: Sometimes Steps to Reproduce: 1. 2. 3. Expected Results: Mozilla should never lock up just because one tab has gone "dead". Also it should perhaps give up/time out a little sooner.
Hi! I'm running Linux. I am working with a digital camera that is connected to the network using TCP/IP. The camera can be configured and accessed using a browser. Therefore I use Mozilla quite a lot. After updating to Mozilla 1.7, I recognize a lack of responsiveness, too. It's hard to give instructions how to reproduce this behaviour. Maybe the Mozilla locks up because I use a lot of pages that contain <FORM> elements.
Mozilla 1.7.3 also hangs. Not only when loading a page but also when switching tabs. This only happens in the Linux version. I've thus downgraded to Mozilla 1.6 and now it works like a charm. No hangs any more. Prompt and careful execution :-)
Richard, please try Mozilla/Firefox with that Engine dated 20040113 (e.g Mozilla 1.6) and see if you still experience the livelocks.
Daniel, I do recall this happening with 1.6, and in fact back several versions before. But it is sufficiently rare that it's hard to find a reproducible test case. (That also means that your suggested test won't work - because there's no way to distinguish between "everything is fine" and "it just hasn't been unlucky yet") However...I did actually find one such case: please look at Bug 253595 Also, see Bug 183122 Regards, Richard
> (That also means that your suggested test won't work - because there's no way to > distinguish between "everything is fine" and "it just hasn't been unlucky yet") When I was using 1.7, the "hangs" were not rare. So when switching back to 1.6 I immediately noticed the difference. Thanks for the links, I'll have a look at the mentioned bugs.

Yes, this is still current. There is a related bug, i.e. bug 253595 which has had recent activity. [A workaround is to install adblock.]
