Very useful extension - thanks! A few enhancement requests:
1. Provide an Option to show or suppress the multiple-tab close warning. I would choose not to have warnings.
PS: I have the Firefox Option "Warn you when closing multiple tabs" un-checked - but that setting only suppresses the warning when closing down Firefox. The context menu tab closure warning always shows!
2. Include a) Close tabs to the right b) Close other tabs. Despite these being available on the default Firefox menu, my habit is to look always at FoxyTab sub-menu for close choices. Your brilliant context menu customization options would allow these to be shown/suppressed as per individual preference. Another reason for having these 'default' close options available on the FoxyTab sub-menu is that the FoxyTab close warning suppression feature (requested above) would apply to these.
3. It would be great if we could configure the FoxyTab icon itself to have an action. I would choose to set it to 'Close all tabs and open a new tab'.
PS: I confess to some of these ideas stemming from my use of the "Multi-Tab Close" extension - would like to see all those features wrapped into FoxyTab, too.
