Then I need to go back and wait for the web application to load for long, which is annoying. Reproducible: Always Steps to Reproduce: 1.Open Gmail 2.Go to another website 3.Immediately click stop Actual Results: Continue to go to the other website or load a blank page Expected Results: Remain in Gmail without changing anything displayed.

What does this have to do with toolbars? elaborate on your step 2? How would you expect to be able to move on to another website? I suggest you look at extensions which will lock individual tabs to prevent changes. (see https://addons.mozilla.org/ ) Also note that Gmail itself prevents a variation of this: by default links outside the app are opened in a new window which might send to a new tab depending on Firefox settings. I suspect this will end up WONTFIX but I'm marking INCOMPLETE pending clarification of what you're requesting and under what circumstances.

Hrmm... I read this twice before commenting and I think I misread the second time... So, aside from stopping dead in it's tracks on esc/stop button press (which is often already the case for me) you want to be able to then hit the back button and not have to wait for it to reload? I'm guessing that will require significant work with bfcache, web app devs, and possibly some of the stuff from the offline cache project. reporter: please clarify but I don't think I'd have closed this so fast if I'd properly read the bug so I'm reopening for now.

Thx for reading. Yes it's not quite about the toolbar stop button, but about the stop function. Going to another website mean typing in the address and hit enter, or click a bookmark. Originally I should click ctrl+bookmark or alt+enter in address bar to open in another tab but sometimes misses it, so the website loads in the original tab which I do not want to alter. So before the display of the original website is changed, I stop it, but it will still continue alter the display, that means it did not stop immediately but has delay.
