I'm having problems with FF. In order to download a file, or to upload/attach a file, I usually have to try multiple times before FF does it. I'll get the open/save dialog boxes, but when clicking the open/save/ok button, the box disappears but nothing happens most of the time. Uploading seems flakier than downloading, but both are giving me problems. I just updated to 55.0.2, and it doesn't work. And it wasn't working with the previous version I had, either (52.x I think). I've completely removed and reinstalled FF through synaptic. I've recreated my user profile. I've removed all add-ons. I've tested different websites. I have no problem doing this in Chrome. Any ideas? thanks
