-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I noticed that Firefox stores content, such as PDF, that was displayed instead of downloaded, in the directory /tmp/mozilla_cer0. I would prefer to send that to an encrypted partition. Where can I configure the path, in Firefox? I don't see a setting. Also, I can't find the button for the advanced settings edit (the large table). It is not in the advanced tab of preferences. At least, I can't find it. I can browse to "about:config", though. Still, I don't see the temporary path in there, anyway. The alternative is creating a symlink, of course. Or moving the entire /tmp to encrypted path... which I hesitate to do. - -- Cheers Carlos E.

Hello

...

I noticed that Firefox stores content, such as PDF, that was displayed instead of downloaded, in the directory /tmp/mozilla_cer0. I would prefer to send that to an encrypted partition.

Where can I configure the path, in Firefox? I don't see a setting.

The following is what I do / use : Type "about:config" Then right click on blank area and create a new string value called browser.cache.disk.parent_directory,set its value to /MY_NEW_TMP_DIRECTORY Regards James -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Ah! Thanks :-) But wait, that would be the cache, which is normally on .mozilla/firefox/RANDOM.default/Cache/ wouldn't it? I don't mean the cache, but the temporary download directory for display by plugins. Such as "display receipt", which is a PDF. -- Cheers / Saludos, Carlos E. R.

I think firefox uses $TMPDIR|$TMP|$TEMP|/tmp in that order, try setting $TMPDIR. -- Per Jessen, Zürich (5.1°C) http://www.hostsuisse.com/ - virtual servers, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Not only Firefox puts private information into /tmp. Because of that, /tmp is a ram disk here, like the systemd default. Go into single mode, cleanup your persistent /tmp, remove the /tmp line from /etc/fstab and # mkdir -p /etc/systemd/system/local-fs.target.wants # ln -s /usr/lib/systemd/system/tmp.mount /etc/systemd/system/local-fs.target.wants/tmp.mount # reboot Gruß Jan -- Nothing will be attempted if all possible objections must first be overcome. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

No no, I can't use a ramdisk. Some of the files I work with are big, and my memory, although it is 8 GiB, is not enough: it swaps. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)

Use a ramdisk for /tmp and tell your program that creates these "some of the files" to put them in a persistent directory. Modeling the exception would be much easier than identifying and reconfiguring every single program that might store private data in /tmp.

No. I still prefer not to use a ramdisk for /tmp, as I have done for decades. No reason to change. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)

Yes, absolutely. I can see there recent receipts in PDF form which I selected "display" instead of "download". It is downloaded then to the temporary directory and then calls a pdf viewer with that file. PDFs here are not displayed internally by Firefox. -- Cheers / Saludos, Carlos E. R.

Because that's the way you want it? If displayed internally (as here in 45.4ESR and 49.0.2), you could save to a place of your choice. Based on absence of reponses here, I'd say ask on moznet or in one of the Mozilla forums what to do to keep FF from saving anything outside your profile directory. That it does so I have to think is at least potentially a security bug. -- "The wise are known for their understanding, and pleasant words are persuasive."

Yes. The internal viewer is far from being good enough, it displays badly many of the PDFs that I have to view. I see also .docx files in that tmp dir. And a .txt file.

The directory has "drwx------" permissions, and the files in there have "-r--------" permissions, so the settings are secure, same as inside home, but more difficult to locate. But as I have a crypto partition, it is preferable to use it. I do not know a mozilla method to change that directory, except to symlink it. This is what I did first. The other solution is to move the entire tmp directory. I did that, not for the system, but for my user: /home/cer/.profile: ... TMPDIR=/data/cripta/cer/tmp which is the safer solution, as it also protects files that might be used by other applications, such as libre office. This might have side effects: what happens if something, say a cron job, runs before I open the crypto partition? Maybe i should test for it, then set it. -- Cheers / Saludos, Carlos E. R.

I'm not sure that's the case (security bug). It's a proper use of tmp. It's supposed to be cleaned up when firefox closes, and that happens correctly on my machines. Files are deleted on firefox close, though the empty dir remains in tmp for next use. My firefox installs call atril (the mate version of evince) to open all pdfs and that's how it works here. Carlos, are the tmp files still there after you close firefox? (or do you not ever close firefox...)

I never close it... as I hibernate the machine, this can mean weeks. Then one day I have to apply updates and reboot, so FF closes. Other times hibernate crashes. The older file in there is from July. Not earlier, which means to me there was a change in FF then. There was supposed to be a cronjob that deleted old /tmp files, but it was superseded with something from systemd that doesn't work right. Upstream says that /tmp should be a ramdisk, so apparently they do not care. Perhaps I should resurrect the old cron script. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
