Where are built in vertical tabs? I don't want to have to trust some unknown extension dev and I want to turn off the horizontal tabs with a menu click.
Why doesn't mozilla care about making a better browser?
Anyone who has more than 6 tabs open at once (i.e. everyone except grandma) should be using vertical tabs.
You dont have to trust the unknown dev. Tree Style Tabs is a Mozilla-recommended addon. The "recommended" badge means that Mozilla reviews the addons code and vouches for its security and performance. Similar to ( or even better than) the Debian repository
Mozilla's approach is in my opinion correct and fitting the open-source spirit. Mozilla shouldn't unnecessarily bloat their core codebase with features not everyone will use. ( For example i personally dont use vertical tabs). However, I do wish that Mozilla would review more addons like they used to in the old days when they had more resources. Of course it is still better than the wild-west that is Chrome's addon marketplace.
Good point. I am a Sidebery user because you can turn off the "tree" aspect of the tabs (the whole point of vertical tabs is to allow you to see enough characters of the tab's name to know at a glance what it is - the last thing I want is to pad those available characters with space).
All the same, vertical browsing is so clearly superior, that it should be built in to the browser. Mozilla not only fails to build it in, they also require ridiculously complex steps to eliminate their dumb horizontal tabs.
