583712 - browser.tabs.tabMinWidth has no effect in Firefox/4.0b2

Status: RESOLVED DUPLICATE of bug 577497

(Firefox :: Settings UI, defect)

Description

[sardaukary]

User-Agent:       Mozilla/5.0 (Windows; Windows NT 5.1; rv:2.0b2) Gecko/20100720 Firefox/4.0b2
Build Identifier: Mozilla/5.0 (Windows; Windows NT 5.1; rv:2.0b2) Gecko/20100720 Firefox/4.0b2

To stop tab scrolling I like to set browser.tabs.tabMinWidth to 5.  This no longer reduces the size of the tabs in Firefox/4.0b2

Reproducible: Always

Steps to Reproduce:
1. Go to about:config
2. enter 'browser.tabs.tabMinWidth' in the filter
3. Change value to 5
4. Restart Firefox
5. Open enough tabs to fill the tab bar.
Actual Results:  
As more tabs are added then can be accommodated the scroll arrows appear and oldest tabs are shifted off screen.

Expected Results:  
browser.tabs.tabMinWidth should be honoured so the tabs shrink to allow more to fit on.

It appears that tabs do shrink but it's not possible to get them as small as you could in FF3. The new hard min limit seems to be about 5 times wider than the old one.

The browser.tabs.tabMinWidth preference got removed on bug 574654 without a good explanation on why the removal was needed.

And the people that could do something about to get the preference back is remaining silence so far.
