1991082 - TypeError: can't access property "linkedBrowser", tab is null appears in console when loading a site from an about:blank tab

Status: RESOLVED FIXED

(Firefox :: Tabbed Browser, defect)

Description

[Jeremy Swinarton]

Discovered while debugging bug1980036. The root cause is that the patch that fixed bug1981200 changed the way that the Tab Hover Preview updatePreview routine was called, such that at the time of the call, the underlying reference to this.#tab was not set (which it requires to populate the contents of the preview panel.

Expected behaviour: no error appears in the browser toolbox console when opening links from the new tab page.
