If you access Privacy & Security -> clear your recent history for a second time the buttons are displayed on the "Clear All History" dialog.

Works for me. Is the problem reproducible in a brand new profile?

I could've sworn I've see this bug before, but I'm having no luck finding the respective report.

Hi Gingerbread Man,

Thanks for the response. I did a Refresh of Firefox and it has worked but I have doubts about the rendering of the dialog. I'm not being finicky but there's something which is not right. Have a look at the two screenshots (F1, F2)and notice how the bottom edge of the buttons is not displayed in the first image and then it appears in the second image.
It seems there's some calculation that's not right the first time and the second time it improves.
Both shots are the same settings of the environment and the Firefox.

If you don't find anything worth investigating, please close the issue.

Thanks.
Gajendra

For info, the issue is observed on windows 10 64-bit OS.
The locale is US-EN.

Hey creative.gajendra, it looks like you're in Windows 10. If you right-click on the Desktop, and choose "Display Settings", under Scale and Layout, what is the "Change the size of text, apps, and other items" set at?

I must've been thinking of bug 1163630, comment 3. That one depends on permanent private browsing mode, so this might not be a duplicate.
