The original Safari behavior of a vertical overflow list of tabs, favicons included, keyboard searchable and navigable, was much more usable. https://i.stack.imgur.com/eyXum.png
Just as humans can adapt to the tab bar shifting when tabs are opened and closed, humans can also adapt to the concept the tab bar focusing on the left or the right and collapsing the opposite side.
The point of my previous comment is you've lost literal spatial organization already, as the exact same position isn't guaranteed to be the same tab after other tabs have opened/closed, so we're already talking about dealing with relative positioning of tabs instead of absolute positioning. And Safari's tab bar does not screw with relative positioning.
Another killer feature for me is that you can basically middle click anything and open it in a new tab, whether a bookmark, back button, etc. Makes some tasks very intuitive and trying to maintain the same workflow on Chrome is extremely frustrating. I cannot understand for the life of me why this isn't a native feature in Chrome.
(I run Nightly and have successfully migrated all my extensions to WebExtensions alternatives with only very minor loss or change of functionality.)
There are really good reasons for the move to WebExtensions, technical, for security and for performance. I was intensely sceptical of the timeline initially announced, but as a Nightly user I can report that November is actually sounding very reasonable now.
Not upgrading your browser leaves you insecure, and within a year or two websites will start breaking on you. In little things of design, mostly, but steadily more and more. Oh, and you’ll miss out on the continuing performance improvements of the Quantum project.
(Also, what would you migrate to? Even without XUL addons, Firefox is still going to be better for what you want than all the mainstream alternatives.)
I've tried to use Chrome for the performance and stability but the lack of multi-row tabs always kept me on Firefox. It's just such an amazing piece of usability.
Imagine if Microsoft just removed the ability to copy/paste in the next version of Windows. Despite the improved performance and security of each successive version of Windows -- would you be so quick to upgrade?
This blackmailing is the worst, and what I hate about modern software.
They seem to resolve most tab issues while also being a better use of space in many use cases.
