Export Tabs URLs Phoenix von clach04

Save a list of all open tabs into a text or (Netscape bookmarks) html file.
Updated fork of the original Export Tabs URLs https://addons.mozilla.org/en-US/firefox/addon/export-tabs-urls-and-titles/ - slightly smaller, with an updated German translation, html export, basic/hidden import URLs support, and an option to disable notifications.

Original Features:
- List the URLs of all the open tabs and copy that list to clipboard or export it to a file
- include titles
- custom format (e.g. markdown, html…)
- filter tabs
- limit to current window
- list non-HTTP(s) URLs
- ignore pinned tabs
