Hi,

The people who answer questions here, for the most part, are other users volunteering their time (like me), not Mozilla employees or developers. If you want to leave feedback for developers, you can go to the Firefox Help menu and select either Share ideas and feedback… or Submit feedback…, depending on your Firefox version. Alternatively, you can use this link. Your feedback gets collected by a team of people who read it and gather data about the most common issues.

You can also file a bug report or feature request. See File a bug report or feature request for Mozilla products for details.

As a possible workaround you can select all those tabs and use "Bookmark Tabs" to bookmarks them. That way you have more control like selecting them in the Bookmarks Manager (Library) and possibly copy links to the clipboard.
