Sometimes Firefox is too smart

[import_that]

Sometimes Firefox is too smart for its own good. I have been annoyed now for a very long time, months if not years, that when saving images with Firefox, the default Save As location will unexpectedly change. One moment I'm saving assorted images to directory X, the next the directory has changed to Y.

It turns out that Firefox remembers what Save As location you last used on a per-domain basis. I'm not the only person this feature has annoyed, and Firefox has a hidden preference to turn it off:

1. Open about:config. (If clicking the link doesn't work, type it in the location bar.)


2. Firefox may warn you that you're about to destroy the Universe void your warranty. Continue regardless.


3. Search for browser.download.lastDir.savePerSite, and set it to false.


4. If that preference doesn't already exist, create it by right-clicking on the blank space, then choosing New > Boolean from the context menu to create it.
