Tabs Export per mortalis

This adds an item to the main menu "Tabs Export" to save to a text file URLs (addresses) of currently opened tabs. The resulting file is downloaded to the general Download directory.

If some tabs are in the unloaded state (e.g., after restarting the browser) they are reloaded before exporting so that the addon gets their URLs correctly. In this case the export process will require more time. If you have all tabs loaded and live (not in the unloaded/sleeping/zombie state) the export is fast.

In the options it's possible to change the Reload delay (in ms) parameter that is used to wait after each tab reload. The delay is necessary to wait until the current tab info is fully loaded. If the final text file doesn't contain correct URLs (about:blank instead of the desired addresses) try to increase that delay value.

After successful export or if any error occurs a notification will appear in the device status bar (slide down the top notification area to see the created message). Currently is the only way to communicate some information to the user.

----------------------------

This is the migration of the old addon Tabs Backup for Firefox 57+.
It was split into 2 addons to add 2 menu items (not possible with 1 addon only). These are Tabs Export and Tabs Import.
To restore tabs from a text file use the Tabs Import addon.
