Guys, we have an entire forum for modifications now. I'm going to lock this thread so it doesn't grow any further. It's a huge collection of totally unrelated things that no user will ever be able to search for. Please start new threads for each modification from now on.
You can discuss separate bugs in a own thread (not all bugs in one!) or in the thread of the related browser version or OS.
You can report bug to Vivaldi Technologies.
How to do a bugreport for Vivaldi
Report every bug seperately at https://vivaldi.com/bugreport/
Describe the issue as precise as you can.
If you use any extensions please give information which ones you use.
If you have a URL or a own testpage which can checked, add it to the bugreport.
If you have own testcase files (HTML, CSS, JS etc.) add them to the confirmation mail you get after report.
If you have a screenrecording video, you can attach it to give the developers a hint how this might happen or look like.
You will get a bug confirmation mail and in a reply to this mail you can add more information and files as attachments for the testers and bug tracking team.
Thanks in advance for helping us to make Vivaldi better!
I must apologize for not replying earlier but I have only just discovered (= taken the trouble to look for and find) this page.
Your remarks of a year ago are now, a year later (obviously) much appreciated.
@Lupin-III With that many tabs open, any multi-process browser will give you a hard time. Luckily, there is a tab hibernation option If that does not work for you, try The Great Suspender extension, works miracles and is very customizable.
