Recently installed MATE 17.04 - clean install on an X220/i5/16GB RAM/250 GB SSD.
My problem is as follows.
When Downloading a (any type) file using Firefox 52.01, when the file download concludes, if you click on the little “display progress of download” arrow on the address bar (RHS), then click on “Open Containing folder” my machine crashes. It sometimes becomes responsive after a minute or 2, sometimes all I can do is bring up a terminal (which is basically all I can do - all menu’s are unresponsive, as is FF, shutdown button, anything in the panel, etc.) search for the PID of FF and kill it.
I have tried:
deleting FF and old profile I had copied across from my old O.S (16.10 Ubuntu Mate) and reinstalled a new copy of FF - via the Package Manager , which created a new profile. No addons or extensions applied.
Disabled everything. Ran FF in safe mode, refreshed FF, reset the browser:download user settings. Still same problem.
Cleared cache, cookies, etc on new fresh FF install.
I have just tried booting 17.04 using a bootable USB drive (ie. running Ubuntu 17.04 Mate from a USB drive) on the same machine. The problem is still present.
5 . I have tried again to change my download location to another newly created folder in my /home directory. The Problem is still present.
Whilst testing FF, I ran “htop” from the command line to see if there was a memory issue. The Firefox PID was only reporting ~2% of CPU & ~1.5% of RAM. I did notice however that whilst FF was crashed, several processes (new PID’s) were being created. Not sure if that’s relevant.
Other programs on my system quite happily let me save and choose a folder to save to.
8 . PDF’s opened via the browser PDF application (Atril) work fine. But if that PDF is Downloaded, and the Download arrow is clicked after D/L completion, then the folder icon to open file location - it crashes.
- I have also tried FF 51 on same machine, and get same thing/problem.
Initially I thought it a FF problem and have submitted this:
But, on further investigation I don’t think it’s FF crashing as I don’t have anything in “about:crashes” in FF.
I have also subsequently gone back to 16.10 (used another SSD) and have no problem with FF and D/L’s.
I am really thinking it’s a MATE problem.
How can I go finding out exactly what is crashing? It’s like the MATE desktop is crashing (I think) …Any other thoughts? Diagnostics I can run?
(excuse numbering, it kinda got wonky after I posted, can’t fix for some reason…)
