This update provides major upgrades to blocking functionality by inserting a script onto webpages that intercepts clicks and stops them before they even start a navigation. This has two benefits: One, it increases the number of situations in which potential navigations are blocked, and Two, it decreases the number of times a potential navigation disrupts the current page state.
Additionally, a few bugs with the initial release were fixed. First, lock state could sometimes be lost if the page is manually refreshed. Second, tab unlocking sometimes didn't work if an already-locked tab was then pinned (thus re-locking it). Finally, tab locking sometimes didn't work if the previous page the tab was on was the new tab page.
Finally, an options page was added in this release with the following options. One: An option to show a lock icon in the tab title (this functionality is new to this release and turned on by default). Two: An option to block navigations entirely instead of opening them in a new tab (turned off by default). Three: An option to open new tabs in the foreground (turned off by default, which is different behavior than in the previous release). Four: An option to automatically lock pinned tabs (this is turned off by default, which is different behavior than in the previous release).
