Separate Security Issue, please update your Flash 11.2 r202 by removing it If you use it Reinstall with Flash Player Version: 30.0.0.134 Current Version https://get.adobe.com/flashplayer/otherversions/ Step 1: Select Operating System Step 2: Select A Version (Firefox, . . . .)

Have you been changing things back to stock when things that you did in about:config change and no longer work ? If you have not been doing this fora extended time it maybe time to create a new Profile and fix those issues.

Is a option instead of doing Refresh.

Please to Refresh : Note that this does more than uninstalling and re-installing does. Normal uninstalling does not remove some preferences which may have become corrupt. Please Refresh but do this 1st: Delete your Cookies and Cache and TEST.

Thank you for the note about Flash. I don't actually use it -- I have it not starting on pages without confirmation -- I should just remove it.

If I move my entire ~/.mozilla/ directory out of the way so Firefox starts completely fresh with no prior settings at all I still see the same problem with an unusable file dialog.

Cheers, Mark

Anything useful in this bug report?

• bug 1268395 - [oxygen-gtk3] open/upload/save file under kde is impossible because of filepicker

(please do not comment in bug reports
https://bugzilla.mozilla.org/page.cgi?id=etiquette.html)

Thanks for the pointer. Naturally it suggests the workaround I mentioned that no longer works. (-: Still, in case of anything relevant to the themes mentioned, I tried hunting around in ~/.kde4/share/ and ~/.config/gtk-*/ and whatnot for anything that looked possibly relevant and stripping it out to see what happened but I didn't observe any change. I don't really know what I'm doing with those though: I'm just a twm user, I don't use a KDE or GNOME desktop environment or change themes; I've no oxygen theme installed. I do have GTK+ 3.22.30 installed if that's relevant.

Cheers, Mark

Support for the builtin XUL based file picker has been removed, so you can no longer use the ui.allow_platform_file_picker to disable the OS file picker.

What theme is currently selected?

You can try to use a different GTK 3 theme to see if you can find one that works.

I don't select anything explicitly, e.g.,

$ cat .config/gtk-*/* [Settings] gtk-primary-button-warps-slider = false $

In /usr/share/gtk-2.0/gtkrc there seems to be "Adwaita" set; maybe GTK3 does the same implicitly somehow.

$ ls -d /usr/share/themes/*/gtk-3* /usr/share/themes/Default/gtk-3.0 /usr/share/themes/Emacs/gtk-3.0 $

Kind of amazing the default one doesn't work if that's the problem. ): I certainly don't see any trace locally of this "oxygen" GTK theme that the bug report mentions.

I'm not having any luck with trying different themes like Adawaita and Breeze. I install them and adjust ~/.config/gtk-3.0/settings.ini to have gtk-theme-name, gtk-icon-theme-name, gtk-cursor-theme-name match them accordingly, and I make sure I've wholly quit out of Firefox before retrying, and it makes no difference to the save dialog problem.

Tried also with ctwm 4.0.2 (which improves some twm misfeatures), same result.
