Package: webext-treestyletab Version: 3.4.7-1 Severity: important I updated to Firefox 76.0-1 this morning and webext-treestyletab no longer works. The toolbar button is still shown, but pushing it (or the "F1" key) no longer opens the tab sidebar.
A different computer has 3.5.3 from addons.mozilla.org installed. That version works fine, so maybe only an update to the current upstream release is needed. Ansgar
