Vivaldi Profile Cleanup Guide

Introduction

Scope

This Guide addresses the following Scenarios:

Important User Data Backup
Importing of User Data into a Profile
Profile Cleanup from Unused Data ~ and hopefully Optimization
Fixing Profile Issues ~ Corruption, Data Loss, Manually made Mistakes, etc.

Warning

Please Note that while this Guide or Parts of it Might work for other Webbrowsers ~ Blindly following it without Proper Research might lead to Data Loss, Corruption or other Issues.
Vivaldi's Internals have become Vastly Different from the ones of Chromium ~ the Project Vivaldi derived from.

Info

This Guide is a WIP!

This is the Beginning of this Guide!
It is in no way complete or usable as of now.
Content will be added as my Knowledge grows, as I have the time to add it ~ and as You Contribute to it 🌷
I'm aware that there is an extensive Forum Post on the Vivaldi Forum on the topic. I will use that post ~ But, this Guide is supposed to be way more verbose & straightforward!

Contributions are Very Welcome ❤️
