Open all in tabs

[sibebleuze]

Is your feature request related to a problem? Please describe.
I'm migrating from Firefox to Waterfox. I wanted to open all open tabs in Firefox also in Waterfox (there's quite a few of them), but where in Firefox I can right click a synced device and "Open all in Tabs", this option is missing in Waterfox.

Describe the solution you'd like
This seems like a useful feature of Firefox that is absent/broken in Waterfox. I believe it would be great if it can be added/restored/...

Describe alternatives you've considered
I currently don't really see an alternative besides manually migrating my open tabs one by one.

Additional context
In Firefox, the feature looks like this. In Waterfox, the right click on the device is not working to even get to the menu where "Open all in Tabs" is supposed to appear.
