How to set location of temporarily download files Firefox linux

Under Ubuntu. If an application is set to be the default file handler for a certain type of file, Firefox will allow you to open such a download directly in the application. To do this, it saves the file in a temporary location, and then hands over to the application. The problem is that the location firefox uses under Linux is /tmp and modern snap and flatpak desktop apps are not allowed to see /tmp.

For instance, a .deb file is an installable software package. Ubuntu naturally uses the Software app to handle .deb files. But Software is a sandboxed snap app, and it won't open files in /tmp

The workaround of saving files and opening them from the app works, but it defeats the purpose of having registered file handlers.

And I do not know how to get firefox to save temporary download files somewhere else. I can't find any relevant configuration option.

I tried editing the firefox launcher:

env TMPDIR=/home/tim/tmp_firefox firefox

but it still uses /tmp

Autofill prevents forms working - at all! Firefox Developer 91.0b5 (64-bit)

Since firefox updated this morning, I'm no longer able to log in to some sites using forms once auto fill is active.

I've created a new blank profile to test, and it's the same behaviour.

1. start blank profile 2. visit https://bandcamp.com/login 3. enter a username and password (doesn't matter that it's not real) and hit Submit 4. tell Firefox to remember password. 5. clear the form and reload the login page. 6. try to allow firefox to auto fill the fields

There's a really weird mix of things that go on

- sometimes one of the fields is populated, more often they both go yellow, but blank. - double clicking in a field seems to momentarily reveal contents, but then it goes blank again. - typing in an apparently blank but yellow field seems to suddenly append characters to the auto-filled value.

Hello, I found very different behaviour today between chrome,brave & firefox,firefoxdevedition with javascript and button.

As visible on the screenshots the button is created with its attributes GET and target profile.html via jinja2 templating.

But in addition, via javascript, I added a function to post the selected tables to a route called SaveToDatabase.


In chrome the js part gets executed and profile.html is loaded, but in firefox based browsers ONLY the js POST is executed and nothing else happens.

What could the problem here be?


Best regards and thank you in advance.
