I love tree style tabs but it takes up a lot of horizontal screen real estate. It's great when my browser is in fullscreen but most of the time I have a terminal on the right half with my browser on the left. This winds up smooshing the actual website to switch to a mobile layout (if I'm lucky). Otherwise the website is rendered useless. Is it possible to make the sidebar float atop the webpage instead of pushing the content in? Then perhaps it could quickly autohide as you move your cursor near it.

You can turn it on and off quickly with the F1 key. And I'm pretty sure the hotkey is configurable.

My situation is a bit different: I have a 4K display, so space is not at such a premium, but I have 70-100 tabs open, in several large subtrees, and smaller subtrees within them, etc. It is possible to make the tree pretty narrow if the screen is small, then the tabs begin to look more like the crowded top tab bar, but still allow for some structure.

My issue is that you can’t disable the default tab bar, so you end up wasting a lot of space by rendering each tab twice. It also makes the habit (of using the default horizontal tabs) a tough one to break.

On wide screen monitors, a maximized browser is almost pointless these days - either lines are uncomfortably long, or on better designed sites, margins are enormous. I generally size my Firefox so that the viewing portal is approximately square - the area with content is as wide as my monitor is high - leaving plenty of space for tab tree on the left, and then another 1/4 of a screen for things like terminals to be cascaded. Cascaded windows are more efficient than tiled or docked windows. The bottom left corner of cascaded windows act a bit like tabs for selecting a window. This is on two 30" monitors. If you're on a laptop then things may be different. On my Macbook, I fullscreen most apps and swipe between them, but I don't do any serious work on laptop screens, they're too small.
- ShamelessC 6y ago
  Sorry, is this in opposition to my comment, in support of it, or just an unrelated tidbit? As I said, I prefer to have my browser at about 50% horizontal width. The only reason I wind up using it in fullscreen is because of the aforementioned issue with tree style tabs taking too much space.
