When uploading files with Firefox, I click the upload button, and the file browser window appears to upload files.

For as long as I can remember, it always defaulted to the last folder location that I uploaded a file, but just a few days ago, it stopped working, and always defaults to my home folder.

How can I make the upload window pop up, default to the last uploaded location? My OS is Linux Mint Cinnamon.

Anytime I open Firefox that pop-up shows, I don't want F-fox opening every time I start PC but there's no option to get it to go away otherwise, or at least that I can see.

Up until the last week, on my iMac, if I clicked on the Firefox button on my bottom toolbar, both of my main FF windows (each with multiple tabs and open all the time) would come to the front of the screen.

Now, only one window comes up and I have to specifically select the other window to see it.

Is this a new behaviour or have I inadvertently deactivated whatever it was that let me do as I have always done previously!

I can't find any setting that appears to refer to this condition.

I have tried five different window managers - none give a reliable permanent opening of Firefox in the primary monitor. Google suggested deleting two files from Profile; I could find only one; deleting it did not produce the desired result. Firefox 'Memory' appears to over-ride any setting.
