Hi Ruud, do you create the 4-5 "home" tabs using one or both of these features:

• On the Options page, Home panel, "Custom URLs..." (How to set the home page)
• Open the pages and pin the tabs (Pinned Tabs - keep favorite websites open and just a click away)

If you close a regular (non-private) window accidentally and Firefox is still running, you can use one of these methods to re-open it:

• Ctrl+Shift+n
• "3-bar" menu button > Library > History > Recently Closed Windows
• "Library" toolbar button > History > Recently Closed Windows
• (menu bar) History > Recently Closed Windows

Hi jscher2000,

I use the Custom URLs option in Options. The home pages are then pinned by the "Pin Tabs" extension, when starting FireFox. Is it necessary to keep the browsing history to keep the homepage settings?

Hi Ruud vd V, the pages listed in Custom URLs should show up in a new window created using any of these methods:

• starting up to your home pages (not restoring your previous session)
• Ctrl+n (on Mac, Command+n)
• New Window from the menu
• Open new window from the Taskbar button "Jump List"

When you "detach" or "tear off" a tab from an existing window, or when you use right-click > Open Link in New Window, Firefox skips over the custom URLs list for that window.

Is that consistent with what you see?

Pinned tabs are tied to a specific window, so you lose pinned tabs if you close this window. You wil either have to close the window with pinned tabs you wish to keep as the last window or close (Quit/Exit) Firefox with all windows still open.

Use one of these to close Firefox if you are currently doing that by clicking the close X on the Firefox title bar to avoid issues with losing pinned tabs

• "3-bar" menu button -> Exit (Power button)
• Windows: File -> Exit
• Mac: Firefox -> Quit Firefox
• Linux: File -> Quit

What you all described as to the expected/default behavior I couldn't reproduce, but it was helpful all the same. It pointed me in the right direction. The problem is with the "Pin Tabs"-extension I use. This extension pins the homepages. I had that extension enabled without having set my homepages yet. Clicking the button to use the "current pages" as homepages did not actually fill the text field with URLs. The only reason it appeared to work is because I restored a previous session. Disabling that extension allowed me to properly set the homepages.

Homepages now work. There is still some weird behavior if I enable the "Pin Tabs"-extension. The homepages are pinned, but the homepages are opened again next to the pinned tabs in normal tabs. But that's not a FireFox problem.
