Bug Description

Binary package hint: firefox-3.0

 I'm using Ubuntu 8.04, and the package 3.0~b4+nobinonly-0ubuntu1 of Firefox 3.0.

When I presse Page up page down, I expected the current page to scroll.
Instead it only scroll locally : it keep the cursor inside the screen, and if the page wasn't clicked, it scroll directly to the top.

Hi Kuda,

My system is the same and page up/page down behaves as I would expect in firefox. It will scroll up and down in whichever area of the page is focused.

Can you perhaps explain what you mean by 'Instead it only scroll locally : it keep the cursor inside the screen, and if the page wasn't clicked, it scroll directly to the top'?

Cheers,
Alex

I mean that, if you click somewhere one the page, a cursur will apear there. Then pressing pageup will scroll the page so that the cursor is at the bottom of the page and you can't scroll up highter with page up, same with page down in reversed direction. I guess by dfefault the cursor is at the top of the page that's why pageup pagedozn send you at the top. (sorry for my poor english)

Can you provide an example webpage where we can reproduce this? Do you mean cursor as in 'mouse cursor' or cursor as in 'there is an input box with a blinking line' cursor?

Well, a long facebook page for example, or Deviant art (Sorry, those are not really good websites, but that's the onlu one's I remember having this problem, because I got used to using the mouse wheel instead since the bugreport). It doesn't happen on every webpage. On this page also, pressing pagedown work fine, but then pageup is blocked at the bottom. http://cs.stanford.edu/People/faculty is also not working properly. but somes like googlenews works fine. I guess this depends on how the frames are arrranged (not sure of the vocabulary, not a native english, sorry). Good luck !

For the urls, my previous post gave somes.

Well, this is weird. On my previous computer I never saw this bug, I was running Firefox 2 on ubuntu 7.10. With my new computer, I tried the ubuntu beta 8.04 with firefox 3.0, and I noticed this strange behavior. I had too much problem with this beta, so a few days ago I downgraded to 7.10, and firefox 2.0. But this behavior is still there : There is a cursor on the page, even in none editable parts. I never saw that on my previous computer, and this cursor seems to interfer with page/pagedown control. The scrolling mouse roll is working fine, but I'm sure something is different : I have always used pageup pagedown and I never noticed that before. But how could that depend on the computer model ??? I'm using a Dell Latitude D610 (Professional version). When using Epiphany web browser, pageup/pagedown act as I expect ( scroll down/up the height of the window) .

More precisely, on this page for example https://bugs.launchpad.net/ubuntu/+source/firefox-3.0/+bug/207116 , when the editing zone is not selected (click on the text of the last post just top to the editing zone), then press pageup or pagedown. Both of them send you close to the top of the page. Then pressing pagedown seems not working. In fact whn looking more precisely, you see blinking (something like 1/10 sec) what you should see : I mean the next part of the page, on window under, but switch back to previous position. I also noticed when doing that on this page, no cursor apears, but pressing pageup or pagedown select my nickname at the top of the page (there is a rect around the icon and the nickname). It act like pressing pageup pagedown was working fine, but after, something get select, so the page scroll to put that selection in the current view, and when it's not a selection, it is the cursor.

I hope I'm clear enough....

Thanks Kuda, but like the other guys, I can't reproduce it.

It's interesting that the mouse wheel works. Are you saying that when the focus is on the text area of a previous comment, that either page up or page down, send you top of the page?

Are you running any extensions? What happens if you try this as a different user, is there something in your personal settings that is messing stuff up?

Cheers,
Al

yup, Ubuntu 8.10 with Firefox 3.0.4 gives me same result.

I never tried using pageup and pagedown in webpages before. Even on this page it seems to create a 'blinking line' cursor in the middle of an area (not necessarily inside a box) then pageup and pagedown only seem to move the cursor a little way within the bounds of the area the cursor has become trapped in.

I find it pretty wierd considering the way that tables are written in html that the cursor cannot escape even very minor obstacles within a page. Of course i can rescue the cursor with a mouse click or the arrow keys but that feels almost like cheating.

I also have this problem. In previous versions of firefox, pgup/pgdown caused scrolling (like a PDF), which makes a lot of intuitive sense to me and which I relied on a lot. I don't care about the internal formatting of the page, and if it has formatting tables, I shouldn't need to know that to see the page. It's especially annoying near the end of a text article -- when you get to the bottom of the text, if you try to use the keyboard to go further it takes you to a "random" point wherever the next formatting column starts. BBC, Slashdot, The Oil Barrel, these all do the same thing.

I'm on a laptop, so without a scroll wheel I used PGUP/PGDN a lot to do that sort of document movement. I was hoping this would be a simple change in some about: page.

Oh, thank god. Someone found out the problem. We are somehow all in "caret mode" and so it is treating the page as a text document instead of as a rendered document.

Hit F7 (on Linux at least) to switch back, and now scrolling works it should again.
