The scroll bar for the "Incompatible addins" list does not work properly. I had a list containing 8 addins that are not compatible with the new version (2.0RC1). The last item on the list was cut off at the bottom. The scroll bar was displayed but when I tried to move it (by clicking and dragging) so I could see the last item it would not move.

Reproducible: Didn't try



Expected Results:  
Scroll bar "Incompatible addins" list should work.
Scroll bar in the picture did not work at the time I took the screen shot.

I can confirm this, also problem on Thunderbird 2 (maybe this bug is core, but i can`t find the correct component at the moment).

Like other bugs show this also happens on trunk. Resetting version number. Cannot test on Linux/Mac to to missing number of extensions. :)

i cc mscott, since this problem also occur on thunderbird 2
Does the scrollbar not move at all or is it only that it cannot be moved further down?
It cannot be moved further down.

It is always the last item which is cut off. I wasn't able to create a testcase with the problem, but it seems as scrollToIndex() doesn't work in my testcase. Furthermore, the "++i" in update.js should be replaced with "i++".

It seems as the applications thinks that the list has one item less and because the list always starts showing a complete listitem, it usually leaves the space less than a listitem at the bottom free, but not in this case.

Let's keep this in Firefox -> Extension / Theme Manager.

The wizard is displayed early during startup which has historically caused problems for widgets in the wizard and we'll most likely have to hack around this as we've had to do previously for other bugs

Ok, sorry about that. You can also later open chrome://mozapps/content/extensions/update.xul to test it.
sethb showed me this on Mozilla/5.0 (Macintosh; U; Intel Mac OS X; en-US; rv:1.9a9pre) Gecko/2007102204 Minefield/3.0a9pre

"At start-up, a Minefield Add-on Update window checking for compatibility.  When
I scroll down, the thumb in the scroll section cannot reach the bottom.  It
appears that I have 9 add-ons that Minefield is searching for compatibility. 
Whether I scroll down or grab the thumb and drag down, I cannot reach the
bottom.  Also, when I get to the eighth add-on, the list of add-ons becomes
very "jumpy", meaning it shifts up-and-down very quickly, causing a very blurry
list of add-ons.  When I release my scroll, it stops, and the list reappears."

Also found this to be true in the new beta of firefox,

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9b1) Gecko/2007110904 Firefox/3.0b1
I also found this in Firefox Beta 1.  The scrollbar seems to skip and jump if I try to scroll all the way to the bottom.  It never gets all the way to the bottom.  It's almost like what you'd use to get if you didn't close the </html> tag properly and the browser wouldn't know where the end of the page was.
Sorry I mean Firefox 3 Beta 1.
This bug has been confirmed and no additional confirmations are needed. Thanks!
Looking at the number of dupes, and the fact that many many people will see this once they update to Firefox 3... Requesting blocking.

Depends on: 413336
Filed bug 413336 which is the widget bug that causes this problem. If that isn't to be fixed however we can work around this. A couple of options come to mind:

1. Remove the label underneath the list, or move it above.
2. Change the listbox from flexing to fixed height, this would likely mean changing the wizard to variable height which I understand is against platform guidelines.

cc'ing madhava for thoughts.
It is unlikely that bug 413336 will get fixed so we should try to rework the UI here.

The same issue occured on FF 3 beta 3.
Flags: blocking-firefox3+ → wanted-firefox3+
I think this bug should have higher priority and block Firefox 3. This is indeed a very minor bug but it have great exposure.

For a lot of people upgrading from Firefox 2 to Firefox 3 the Incompatible add-ons dialog will be the first thing they will see.

Here the reaction I got when I first tried Firefox 3:

"This is great, I just hit a bug after 5 seconds of use"
I agree that this is a very minor bug, but it's one of the first things you see when upgrading.  I am humbly requesting a higher priority.  It would be nice to see this fixed when FF3 final is released.
I ran into this bug with the FF3 release and agree with François Gagné and Joe that the bug should be given a priority boost because it gives a poor first impression. Admittedly, this bug will only be seen by advanced users with many add-ons, but they are the ones most likely to be vocal.

I can confirm also.  I have a video capture (if wanted/needed) but I can't attach here (3mb zip file of an AVI file) due to size constraints.  Email me if you'd like a copy. ;-)
This bug is well known and its cause even identified, additional information is not necessary

Neither of those is great, but I think 2 is probably the best choice between the two. The description sets he context of the action button "check now", and we are after string freeze so we can't reword the directions into a single statement to place above the listbox.
Keywords: uiwanted
Couldn't the available height be used to set the height for the listbox in JavaScript?
Wouldn't the easiest fix (hack) be to add a blank entry to the bottom of the displayed list?

I have also recorded a video of this bug.

Here is the link to that video (no download):

Mine is 4 MB in AVI format but zipped is ≈300 kB ;)
Please, there really is no need for additional screenshots and demonstrations, this the problem here is easily reproducable.
Same problem on my machine.  Can't scroll through the add-ons at all.  Also the new interface takes up too much space.
Dave, is this a wontfix now regarding our work for new add-ons manager and lesser distractions during the start-up process?

We have no replacement UI for this yet so it may end up coming back so I'd rather keep this open for now.
This issue is still being experienced in 4.0b5.

Is it intended for the replacement UI to be created prior to the production release or will that be for a 4.1 update?
There is going to be no replacement for 4.0
Version 4.2 does the same thing...
Why is it taking FIVE YEARS to fix a scroll bar issue?  As evidenced in comment 48, if the cause is known, why can't a small patch be written?  Why not just use the operating system default scroll bar, which takes into account how many items are popularized in the list and generates the scroll bar only when necessary?  This is a dialog box that many users see when starting Firefox for the very first time and I agree with comment 42 that this bug should have a higher priority rating, since on this page alone there are 46 instances of "Bug ###### has been marked as a duplicate of this bug."  Don't you think that is cause for concern if there are that many bug reports on this one issue?

> Why is it taking FIVE YEARS to fix a scroll bar issue?

You might want to review the Bugzilla Etiquette page. https://bugzilla.mozilla.org/page.cgi?id=etiquette.html

I suspect the large number of duplicates reflect the fact that it is an easy bug to notice, not that it is a major problem. It does make Mozilla look sloppy, but users can still use Firefox, it doesn't leak memory, it doesn't cause crashes, it doesn't lose data.

And if you are really annoyed, feel free to grab the Firefox source and fix the issue yourself. I'm sure the developers would be glad to accept a patch. (You might want to start with the hack I suggested in comment 54.)
(In reply to comment #54 and comment #82)
That'd be adding the code to add an unlabeled item at line 195 in omni.jar\chrome\toolkit\content\mozapps\extensions\update.js

The problem is: this would create an selectable item which might be reported as bug again. Imagine you get a blank item, you'd also wonder what it is for, if that's an add-on or what. And maybe you'd even think it's responsible for the scrolling problem. No, instead of searching any hacks for this bug, I'd rather try to fix Bug 413336 as it is the real source. (I already dug into the code deeply and will continue to do so.)
Can't the box just be autosized to the number of lines without any scrollbar at all?  I am just thinking past the two suggestions made in 2008 (#30).

You can never guarantee that a list (any particular list) will never be longer than the height of your screen, so if you don't want scrollbars you'll have to put scroll buttons at top and bottom, which is worse, especially for long lists.
Can't the box be autosized to the necessary number of columns as well?  I am sure that a max of three columns screen height would solve the problem for 99.9% of the people and fit the screen just fine.
I just saw the same problem in newest Firefox 7.0 (Windows Vista 64 Bit).
Scroll bar in "Incompatible add-ons" can be moved to bottom.
Just jumps up a bit when moving to bottom. 
I attach a screenshot.
Same in 7.0.1 (Windows XP)


Just put the list in a regular text area, for Christs sake!
It seems to be replaced with a different UI in 8.0b1.

Hasn't this box gone away with the streamlined/silent updates?

I can't test right now, but maybe we could close the bug?

No this UI still exists
