This is an emergency release to fix an issue causing differential updates to fail. The issue primarily affected Firefox because of uBO's use of indexedDB prior to 1.57.0. The issue did not affect full update of filter lists even though the asset viewer would show old versions of those lists (internally uBO compiles lists and would still correctly compile from lists fetched by full updater).

Readiness status at browser launch

uBO's toolbar icon will now reflect its readiness status at browser launch.

Code viewer

Investigating filter issues can be a serious time sink, and to help with this, a code viewer has been added to uBO. The code viewer will automatically beautify HTML/CSS/JS code, which should be an improvement over the browser built-in view-source tool.

You can view beautified source code of HTML/CSS/JS resources when clicking the link in a logger entry. Additionally, if the advanced setting filterAuthorMode is set to true, an entry labelled View source code... will be added to the context menu, so that you can view the source code of any page/resource without having to open the logger.

Fixes / changes

• Fix broken http header filtering
• Prevent dashboard from loading at browser launch until ready
• Support removing whole lines of text with regex in m3u-prune scriptlet
• Fix broken filter parsing when prepended with spaces
• Context of about:blank is that of parent frame (popup option)
• Add experimental href-sanitizer scriptlet
• Prevent dialog box from overflowing logger's viewport
