From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.3) Gecko/20010801 BuildID: 2001080104 When I want to open a file on the browser and am choosing a sub-directory, I have to double click VERY fast to open the directory. The maximum time interval between the clicks should be increased or better yet, open the directory on a single click. The button to proceed upwards in the directory tree (towards the root) works on a single click. Proceeding toward the files should also work on a single click. Reproducible: Always Steps to Reproduce: 1.Select File/Open File 2.Choose a directory in the "Open File" window by double clicking on it 3. Actual Results: If I don't double-click very rapidly the directory isn't selected Expected Results: The directory should be selected with a single click or with a double click with a longer time interval between the clicks allowed

With 20010827 Linux, it does seem you have to click a bit faster than usual, though it's not unbearably quick. confirming, downgrading, -> event handling note also bug 53485 for historical reasons

Sounds like a problem with the native Linux file picker.

I'm not able to reproduce this, and even if I was, we get double click events from GTK... so Mozilla isn't doing anything special here.
