You can find this item now in the History menu, just like others as Restore Previous Session and Recently Closed Tabs/Windows

Thanks. I found it by reading a description on a Mozilla addons page. Why did nobody mention that something was moved from one menu to another in the release notes? I actually read the release notes page for FF 21 and there is not a word about that there. I rarely open the History menu, which is why I did not notice that item in there. I'll be opening that menu a lot more now.

Can`t finde Clear private data in Firefox 21

Hi terrace

Don't you see History > Clear Recent History?

Thank You, My main problem is>Usually when I click on “clear search history” at the bottom of the drop down in Google search bar it clears everything as well as what`s in the search bar, but it`s not happening. Terry

Try to set the gfx.content.azure.enabled pref to false or if this didn't help disable Direct2D by setting the gfx.direct2d.disabled pref to true on the about:config page and leave hardware acceleration otherwise enabled.

That way you still have the benefit from hardware acceleration, but may not suffer from rendering issues.

You can also try to uninstall Windows update KB2670838 if you have this update.
