Mozilla/5.0 (Windows NT 6.1; rv:2.0b10pre) Gecko/20110125 Firefox/4.0b10pre Having the "Show tab previews in Windows taskbar" option checked and opening more than 20 tabs creates a preview only for the last opened tab. Reproducible: Always Prerequisites: - Options|Tabs -> Show tab previews in Windows taskbar is checked Steps to reproduce: 1. Open 5 tabs, hover with mouse over Firefox button in taskbar and observe behavior 2. Open more than 20 tabs and observe behavior again Actual results: - preview is displayed for the last opened tab Expected results: - even if there are more than 20 pages opened, the list with all the opened tabs should be displayed (if list is too big to fit screen, scroll buttons should appear)
It should be displaying a vertical list of tab titles when the number of tabs exceed the width of the tab bar. On my W7 system this behaves as expected.

Yes, as you get the 21st tab the Windows task bar shifts from the stacked window/tab style to the single window style. Using the trunk build or b10.
This is on purpose. You can change this setting by going to about:config and changing the value of browser.taskbar.previews.max Hope this helps

I understand Felipe, but this could be problematic for the average user who doesn't know how to change that variable. For him/her it would just look like an abnormal behavior. (Opera has similar feature, which is not limited by default to 20 opened tabs - just to have a look at the competition)

Because I loved the prevarious version of Mozilla FF that fire fox displayed all this tabs. tnx any way
type about:config in the address bar then use the filter line to find browser.taskbar.previews.max
