If the previously active tab in the target window was not right-most – and if the target window is not foregrounded when targeted – then aiming to open a link in the window:

• will activate the tab to the right in the target window
• will not open the link.

Workaround

Always bring target window to foreground.

Environment

• historically, Waterfox 56.0 was based on Firefox 56.0.2
• with security fixes etc. it's now Waterfox Classic 2019.10.

Would it be possible to open a link not in an existing, but in a new window?

Also, could there be separate options to open this new window in the foreground or in the background?

Regards

I see this in the Browser Console --

"Open https://github.com/kyuucr at window-161 in foreground"

-- but focus does not shift to the new tab. Is this by design?

A user may prefer to add a link to a regular or a private window, but currently it is difficult to tell which is which. The information hopefully is easy to retrieve --

https://developer.mozilla.org/Add-ons/WebExtensions/API/windows/Window

-- but I'm not sure of the best UI. Perhaps you could use the icons property to show the mask:

https://developer.mozilla.org/Add-ons/WebExtensions/API/menus/create

and make that an optional third argument to generateItem().

It is possible in Firefox to have the window itself titled differently than the currently focused tab. When this happens, even though the Window menu and the OS switcher show the actual window titles, the "Open in other window" submenu still lists the focused tab title instead of the actual window title.

The Window Titler extension will let you rename the windows, and it seems at first glance that it would make life with Open Link in Other Window much easier since you know which window is which without having to remember what tab was open in it, until you discover that OLOW doesn't see the customized titles (even though everywhere else that uses window titles does).

Would it be possible to associate the action "open the link in the last opened other windows" to a shortcut?

Let's say I have only 2 firefox windows. I'd like to press Alt + left mouse button (or middle button) and open the link in the other opened windows.

Apart from that, thanks for this extension: I find it useful when I read a webpage that describes something (eg. a paint, a map) and I want to look both at this webpage and the described things. Your extension reminds me the "page preview" feature on en.wikipedia.org but if it had the keybinding it'd be definitely better :)

I would like to report a bug....when tabs are moved from an existing window to create a new window, right click a link and selecting the Open Link in Other Window extension shows no other windows, only if new windows are opened from the toolbar menu. Is this a bug or intentional feature?

Thanks in advance!

When dragging tab to the lower part of the screen, it will be created as a new window, the new window won't appear on the window list
