Firefox filling /tmp up completely with invisible files

[Ant P.]

I'm using a netbook with /tmp mounted as a 128MB tmpfs. Recently I noticed various things breaking in bizarre ways, like bash-completion not being able to tab complete. I've tracked that down to /tmp being 100% full, which in turn looks to be caused by firefox using it as a dumping ground for cached HTML5 media files and never closing the filehandles after it's done with them.

Is there any way to make the browser behave itself, either by a size limit or getting it to write to disk instead?

If you mean /tmp/mozilla-media-cache/, I suggest you to symlink that directory to a directory on your disk as I am unaware of configuration; you can for example do this by creating an executable shell script with the .start extension in /etc/local.d/.

If you mean the cache, although I think it is already on the disk, you can do:

1. Open about:config.
2. Adjust browser.cache.disk.smart_size.enabled to false and set browser.cache.disk.capacity to the preferred value.
3. If you want it to write to disk, you can create a string browser.cache.disk.parent_directory and set it to the preferred location.
