It is rather difficult to describe what has happened. But let me try. Basically, when I try to load an URL for one page under a tab shows nothing in the window shown when that tab is selected, BUT it turns out that the image is loaded into a different window under a DIFFERENT tab. That is the association between the URLs and TABs got mixed up! This has happened when I tried to load several pages by - firstly, searching URLs using google. and then LOOP: - trying to load interesting URLs using open URL under a different tab. - some pages were so slow loading and so I canceled it by hitting stop button. - I occasionally removed tabs when there are too many tabs. - repeat the above Loop. ne Then I realize that one page under a tab never shows its contents. But the message at the lower-left corner of the mozilla window says Loading and eventually "Document: Done." But nothig is shown. A blank page is shown. *BUT* when I opened the right tab (i.e., the tab that is immediately to the right of the tab in question) I see the contents of the URL which I have tried to load and saw nothing of the contents previously. BUT the right tab has different URL associated with it and so this is wrong! (The tab name is different one.) I confirmed that the right tab is indeed associated with different URL by trying to reload under that tab: it would try to load the original URL associated with that tab and not the URL that comes from the left tab. I suspect that there is a race somewhere in the handling of - tab and its url association and handling of cancellation of the loading of a page under a tab by user's hitting stop button. It is easy to imagine such a bug can creep in. My guess is that the internal data structure for the tab (the left one) somehow picked up the window area for the right tab as its painting area when the race condition tanbled some pointers. This bug may be hard to believe, and nothing like this has happened in the 9 months I have used Mozilla beta so far. I was surprised myself. I have uploaded two PNG figures to show the symptoms described above. (Otherwise, people may not understand the description above.) (1) http://www.yk.rim.or.jp/~ishikawa/toms.png (2) http://www.yk.rim.or.jp/~ishikawa/sud.png The fist picture shows the screen when a tab for a certain www.tomshardware.com URL is selected. It shows the blank window and "Done." message. The tab is the second rightmost one. This is where I tried to load a page and saw nothing. The second picture shows the screen when a tab for a certain www.sudhian.com was chosen. The rightmost tab is the one. (The picture is rather large, sorry about this. you may need to scroll to the right to make sure you see the correct tab.) Note the name of the tab. *BUT* the contents of the window shown is the one for the www.tomshardware.com site!!! (which was just loaded using the second right-most tab.) Well, race condititions in handling stopped/cancelled loading at the inappropriate time can certainly result in interesting bug, can't it? I was so puzzled about what has happened and it took me quite a while to what was going on. (I tried to load tomshardware.com many times to no avail [ not seeing the picture. ] and then I realize that the right tab showed desired contents and initially I thought someone at the URL was stealing the web contents from tomshardware.com site and got quite disturbed. But it turned out to be mozilla bug, I think.

chiaki, you selected Mac System 8.0 when you filed this bug. Are you, in fact, using Mac OS 8.0? If so, Mozilla doesn't support Mac OS versions older than 8.5.
After greg's post, I realized that I didn't set the system info correctly. I am using mozilla 1.1 on linux PC (x86). Debian GNU/Linux kernel 2.4.19. Can I simply change the OS/platform setting by submitting this? (Well, I am trying ...)
OS: Mac System 8.0 → Linux
Hardware: Macintosh → PC
Confirming this with Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3b) Gecko/20030116 The way to reproduce this for me, is to start loading multiple slow loading URL-s (maybe disconnect network to facilitate name resolution lookup?) at the same time (all should show "Loading ..."), than when one starts to arrive click on the tab, than click on a different tab and you should see the same URL loaded into different tabs, which is incorrect.
Reporter can you reproduce this bug with a newer build (1.4 final)? If not, then please close this bug as worksforme. Thanks.
unable to reproduce with latest linux builds on fedora core 1.
