Tool for merging firefox bookmarks backups. Designed for people who don't want to use cloud based tools like firefox sync, plugins, want to version control their bookmarks backups or have any other reason to do this locally.
In top menu Bookmarks under Show All Bookmarks there is button Import and Backup which allows you to perform those operations either using json or html file. This module uses and generates json backups.
Creating simple tree structure showing all firefox bookmarks in menu, toolbar and starred.
python firefox_bookmarks_merger --list --files bookmarks-20XX-XX-XX.json --output output.txt
Merge two or more backup files into one. First one is considered "primary". Bookmarks from next backup files will be appended (if there is no duplication). Folders with same name are not merged, but duplication removal is recursive.
python firefox_bookmarks_merger --merge --files bookmarks-20XX-XX-XX.json bookmarks-20YY-YY-YY.json --output output.json
Simple merge of two or more backup files. Each additional backup after primary is given his own folder in primary backup and all bookmarks are stored there, without duplicate removal. To put it simple, in example below, there will be folder named bookmarks-20YY-YY-YY.json generated alongside bookmarks from bookmarks-20XX-XX-XX.json with whole list stored there.
python firefox_bookmarks_merger --merge-to-subdir --files bookmarks-20XX-XX-XX.json bookmarks-20YY-YY-YY.json --output output.json
usage: firefox_bookmarks_merger [-h] (--list | --merge | --merge-to-subdir)
--files FILES [FILES ...] --output OUTPUT
optional arguments:
-h, --help show this help message and exit
--list Print titles and urls of all bookmarks
--merge Merge bookmarks with duplicate removal
--merge-to-subdir Create additional folder for merged bookmarks
--files FILES [FILES ...]
List of files to process
--output OUTPUT Output file
