Waiting for Vertical tabs in Firefox? Official Nightly builds now offer this feature, allowing you to enable and even move it to right side.
The most requested Vertical Tabs will make an appearance in the upcoming Firefox. The feature can now be turned on in Nightly itself without the need to rely on third-party extensions or separate Nightly builds.
Is this just placing them vertically, nothing else?
I currently use the Tree Style Tab extension and really like how it handles sub-tabs and allows collapsing the tree nodes. If I can't have that this is probably not directly useful to me unless extensions can add that functionality.
After all, it's called Vertical Tabs, not Nested Tree Tabs.
unless extensions can add that functionality
I guess that's the idea. Most sidebar extensions need reworking with the new sidebar, but now addons wanting to add functionality to the tab strip no longer have to first also "invent" the whole vertical tab strip. They can just start from the existing one.
I'm in a similar boat. I use Sidebery which has groups of tabs (in addition to nesting them). Would really want something similar built in natively to organize all of them.
