The unlimitedStorage permission has been added in Firefox, to bring uBO inline with the Chromium version. As a result, when uBO updates, Firefox will notify you about the new permission.

Note that the Chromium version of uBO has declared the unlimitedStorage permission since it was first published in 2014.

Firefox is not yet enforcing this permission, but I decided to add it anyways since Firefox states:

Only ask for "unlimitedStorage" permission if you expect your extension's local data storage to exceed 5MB if it's not going to exceed that amount, don't ask for it.

uBO is already using more than 5MB of storage in its basic configuration. uBO's cache storage is used to store filter lists, their compiled counterparts, and snapshots of various internal data structures for fast launch time).

New features

New cosmetic procedural operator: :nth-ancestor(x), where x is the distance from the currently selected node. It is effectively a low-overhead equivalent to :xpath(..[/..]*). Example:


Could be rewritten with the new operator:


The new operator has a lower overhead as it avoids the need to create and execute XPath expressions.
