firefox-45.0.2-2.fc24 has been submitted as an update to Fedora 24. https://bodhi.fedoraproject.org/updates/FEDORA-2016-cebfb38250 firefox-45.0.2-2.fc24 has been pushed to the Fedora 24 testing repository. If problems still persist, please make note of it in this bug report. See https://fedoraproject.org/wiki/QA:Updates_Testing for instructions on how to install test updates. You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-2016-cebfb38250 Proposing as a Beta freeze exception. Note this is a kind of proxy for many "Firefox crashes occasionally" bugs filed by various people for F24, many/all of which should be fixed by this update. I filed one of them, and Firefox does seem to have been less crash-y since this update came along. Others explicitly mentioned in the update are https://bugzilla.redhat.com/show_bug.cgi?id=1327817 and https://bugzilla.redhat.com/show_bug.cgi?id=1324161 . Firefox is, obviously, on most of the desktop live images, and it'd be a good thing if it was as un-crashy as possible in the lives and immediately after install. +1 FE +1 FE +1 FE The Cabal has spoken, marked accepted. Also, there is no cabal. firefox-45.0.2-2.fc24 has been pushed to the Fedora 24 stable repository. If problems still persist, please make note of it in this bug report. Has this been fixed upstream? E.g. a -fsanitize=undefined build should catch all such bugs. Yes, it's fixed upstream already. |
