I'm seeing this problem in Firefox 49, did not previously see it in 45. As a workaround, you can disable the OS file picker. Visit about:config, search for this setting and set it to false:
ui.allow_platform_file_picker -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1578900 Title: file chooser broken since last update Status in firefox package in Ubuntu: Confirmed Bug description: since last update (maybe a week? two weeks?) whenever I use the Open/Save option, the file chooser/browser works very, very badly... none of the "Places" shortcuts, on the LHS, work - neither do the "Devices" shortcuts as for my own "Bookmarks" shortcuts, they appear to be suffering from some kind of "sticky click" where as soon as you click on one, it tries to move this to somewhere instead of activating it - only if you put it back where it was (or move it up or down among the other Bookmarks) does it actually function and allow you to choose a file path I have attached a screenshot to help demonstrate this (note: choosing the file to attach to this bug report had the same issue - even clicking on the path along the top behaves erratically) ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: firefox 46.0+build5-0ubuntu0.14.04.2 ProcVersionSignature: Ubuntu 3.13.0-85.129-generic 3.13.11-ckt36 Uname: Linux 3.13.0-85-generic x86_64 AddonCompatCheckDisabled: False ApportVersion: 2.14.1-0ubuntu3.18 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: mic 2996 F.... pulseaudio BuildID: 20160425115534 Channel: Unavailable CurrentDesktop: KDE Date: Fri May 6 12:50:08 2016 Extensions: extensions.sqlite corrupt or missing ForcedLayersAccel: False IncompatibleExtensions: Unavailable (corrupt or non-existant compatibility.ini or extensions.sqlite) InstallationDate: Installed on 2015-02-08 (452 days ago) InstallationMedia: Kubuntu 14.04 LTS "Trusty Tahr" - Release amd64 (20140416.1) IpRoute: default via 10.0.0.234 dev eth0 proto static 10.0.0.0/24 dev eth0 proto kernel scope link src 10.0.0.90 metric 1 10.0.0.0/24 dev wlan0 proto kernel scope link src 10.0.0.33 metric 9 Locales: extensions.sqlite corrupt or missing MostRecentCrashID: bp-a174f844-044e-49aa-83f0-9f89b2150514 Plugins: Java(TM) Plug-in 10.80.2 - /usr/lib/jvm/java-7-oracle/jre/lib/amd64/libnpjp2.so Shockwave Flash - /usr/lib/flashplugin-installer/libflashplayer.so PrefSources: prefs.js [Profile]/extensions/{3d7eb24f-2740-49df-8937-200b1cc08f8a}/defaults/preferences/flashblock.js [Profile]/extensions/anttool...@ant.com/defaults/preferences/defaults.js ProcEnviron: LANGUAGE=en_AU:en PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_AU.UTF-8 SHELL=/bin/bash Profiles: Profile0 (Default) - LastVersion=46.0/20160425115534 (In use) RunningIncompatibleAddons: False SourcePackage: firefox SubmittedCrashIDs: bp-a174f844-044e-49aa-83f0-9f89b2150514 bp-48e477c4-c94f-4030-a757-2c0022150402 Themes: extensions.sqlite corrupt or missing UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 10/07/2009 dmi.bios.vendor: Acer dmi.bios.version: V1.27 dmi.board.asset.tag: Base Board Asset Tag dmi.board.name: TravelMate 8471 dmi.board.vendor: Acer dmi.board.version: PSMBOU-1234567 dmi.chassis.type: 10 dmi.chassis.vendor: Acer dmi.chassis.version: None dmi.modalias: dmi:bvnAcer:bvrV1.27:bd10/07/2009:svnAcer:pnTravelMate8471:pvrV1.27:rvnAcer:rnTravelMate8471:rvrPSMBOU-1234567:cvnAcer:ct10:cvrNone: dmi.product.name: TravelMate 8471 dmi.product.version: V1.27 dmi.sys.vendor: Acer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1578900/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
