It always bothers me about this whole vertical tab concept, that, on a theoretical level, I'm fully on board with what you're saying. But in practice, I'll often have Firefox tiled side-by-side with another window, and then it's painful for that sidebar to take up any space at all.
I am happy, though, that this feature is being integrated for the people that find it useful.
I have a keybind to close the tab side window. Works pretty nicely when i have firefox tiled beside some other window. I don't need to see the tabs all the time. But when i am looking at them; it's nice to have them stacked, on the side.
But how are you going to read the title of the tab without making the sidebar too wide? That's like having a vertical taskbar in the days before Windows 7 came out.
...same way I'm able to read the title on a horizontal tab? it's even easier since the vertical ones don't shrink in size when they reach a certain number, like the horizontal ones do.
Exactly. Monitors are horizontal. Tab names are horizontal. They should be listed vertically with the names written horizontally. You can hide them if you need to, but I find my monitor has plenty of space.
Try using tree style tabs, it's really great. Most websites are laid out such that there's tons of wasted horizontal space and vertical space is limited, so you increase usable screen space by moving tabs to the side. Additionally, with tabs at the top, the more tabs you have, the harder they are to read and keep organized. With tree style tabs, no matter how many you have, they're always maximally readable, and the ability to nest them and collapse groups gives you a ton of power organization wise. You can also easily hide the sidebar when you DO need the extra horizontal space. The ability to bookmark groups of tabs at once makes it much easier to keep close tabs you aren't actively using.
We spend so much time using web browsers, why not optimize them for human use?
