655180 - incorrect spacing between T and small letter in Times New Roman

Status: UNCONFIRMED

(Core :: Layout: Text and Fonts, defect)

Description

[rog3rli]

User-Agent:       Mozilla/5.0 (Windows NT 5.1; rv:2.0.1) Gecko/20100101 Firefox/4.0.1
Build Identifier: Mozilla/5.0 (Windows NT 5.1; rv:2.0.1) Gecko/20100101 Firefox/4.0.1

I'm not sure if my computer or font thing is messed up, but in Times New Roman font in Firefox, such as address or search bar (maybe other fonts not sure) if you type certain letters together it gets squeezed together, bad spacing.
It's fairly obvious because the spacing is larger in something like MSWord
sequences like Ta, Tc, Te, Tr and probably more

Reproducible: Always

Steps to Reproduce:
1.just go to the search bar or whatever
2.type in Tr
3.

Actual Results:  
Tr is squeezed together incorrectly, the r is below the T, in the right "caved in" part

Expected Results:  
normal spacing

Please attach a screenshot showing the issue.

Does the issue still occur if you start Firefox in Safe Mode? http://support.mozilla.com/en-US/kb/Safe+Mode

Does this happen in text boxes (like this comment field) or other locations, or only in the search bar?

it seems to happen on the Firefox bars. I'm not good at terminology, but what I mean is. the spacing is always fine on webpages textboxes and input fields and stuff. by bars I mean anything that is an input field for firefox i guess? like if I bookmark something, the glitch happens in the input fields, but if I input something into the google search bar, its fine. though that may be google's formatting or something
I doubt it'll happen in monospace formatted input fields

And it occurs in safe mode and a new profile?

Does it occur in the location bar (the place that shows the URL [https://bugzilla.mozilla.org] as an example)?

Can you upgrade to FF 5 and see if it continues?

Does this problem go away if harfbuzz is disabled?

Note that the font shown in the screenshot is *not* Times New Roman, as claimed. It's probably Tahoma.

well, i was never really good with fonts, all I knew was that it looked buggy.

Apologies for the double post, not familiar with how Bugzilla works yet. :(

The bug as initially described is still present in Firefox 9 running on an English Windows XP SP3. Also, it's barely noticable, but the pages being rendered are also subject to this bug in addition to Firefox's GUI itself.

Profiles do not seem to be a factor as I also experience the same bug on Pale Moon 8 (an unofficial fork based on Firefox 8, which also had the bug) with a new profile there.

Any attempts to disable what I presume the bug to be ligature via userChrome.css has proven fruitless. Is this bug being fixed any time soon?

This problem is confirmed to STILL EXIST under Firefox 10.0 final release under Windows XP SP3 (32bit)

If I set harfbuzz to 2 instead of the default 3, the problem goes away.
