This is also happening in textboxs such as the address bar or the find bar.

I've first reported this only in Firefox, but now I saw this error in Tunderbird
also.

I don't know to which product should I change it...

still not working for me, but it had some changes in its behavior

type "0123"
type "´" 
now it only deletes the "3"
but should only delete the invisible "´"

[Wayne Mery (:wsmwk)]

what version?  (copy your build information from help|about)
why are your accent characters "invisible"?  They shouldn't be invisible, no?
if firefox 2, does it happen if you start FF in http://kb.mozillazine.org/Safe_mode

My version is:
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9b2pre) Gecko/2007111104 Minefield/3.0b2pre

I think the motif of my accented characters to be invisible is because I use a latin encoding so the accented character goes invisible "waiting" for the next letter it will be accenting ( like in é )

I can see this in utf-8 and in Western (iso 8859-1), 
This bug also bites in safe mode ...

Also I have my language set to Portuguese in the windows panel control

[Wayne Mery (:wsmwk)]

Serge, do you also see this in whichever browser you are using?

(new) Bug confirmed, per comment 10:
on W2K fr, with French keyboard; tried "^¨~" accent keys.

I noticed 3 different behaviors:
B1) "Mozilla" apps: Forgets the accent key; then removes the previous character.
B2) MS-Explorer, MS-Notepad, OpenOffice: Forgets the accent key; and leaves the string as is.
B3) MS-WordPad, NotePad++: Removes the previous character; then adds the accent character itself.

I'm no expert, but I would think: B1 is wrong, B2 correct, B3 odd.

(system wide) Workaround: press "space" before "backspace" ... The accent character itself will be added then removed :->

(I had a look but didn't find any generic "Keyboard Handling" component around :-/)

"editor" should be a close fit.  thanks Serge.

Comment 17

[Wayne Mery (:wsmwk)]

for intl users I would expect this to be more than an annoyance.

Comment 18

[Robert O'Callahan (:roc) (email my personal email if necessary)]

Simon's probably interested in this. We could take a patch, but it won't block.

Comment 19

[Lichti]

same problem with SeaMonkey 1.1.7 (Mozilla/5.0 (Windows; U; Windows NT 5.1; de-AT; rv:1.8.1.11) Gecko/20071128 SeaMonkey/1.1.7)
Deleting an accent (not an accentuated character) by typing backspace deletes the two previous characters as well.
