Mozilla is reportedly rushing to fix several regressions in the latest security update to the Firefox browser, version 22.214.171.124. The patch could be available as early as next week, and will address problems with startup crashes (on XP), two page-rendering issues (all versions), and an odd bug that disables extensions on a fraction of Windows PCs.
I’ve noticed some issues with the toolbar reverting to default state, adding things back and removing others, and the address bar failed to respond to the return key earlier today until I restarted the browser, but I have definitely seen the toolbar bug before, and the return key problem happened at the same time as the toolbar messing itself up, so I don’t think those are regressions. I believe the toolbar issues to be a problem with the Google Toolbar, actually, since it is usually the only bar affected. We shall see about the return key thing, but since I’m testing out a new skin, I’m not worried, especially since it fixed itself after repairing the toolbar and restarting the browser.
