I am not sure this is the correct forum but I will give it a shot...

Long ago in a galaxy far far away I did some programming in Visual Basic on Windoze. I recall that dialog windows could be modeless or modal. A modal dialog prevented the user from doing anything else in the application until the dialog was dealt with. I think there were also "system" modal dialogs which prevented ANYTHING else from being accessed until the dialog was dealt with. Which brings me to what I noticed today...

I am running CentOS 7 with the Mate desktop from epel. I have 6 workspaces setup. I was running Firefox 78.8.0esr and accessing a financial web site. During the process Firefox brought up a dialog telling me that the web site was wanting to access my location. I have this configured in the Firefox preferences so it was on unexpected. What was unexpected was that this dialog covers not only the Firefox instance and anything else I invoke on that workspace but it is on top of ALL workspaces. Rather a pain as I wanted to do some other work on a different workspace while I was on hold waiting to speak with someone a the financial company to find out if the location was necessary for the process I was attempting to complete.

I am wondering "who" controls the behavior of this dialog? I can go to another workspace which has a virtual machine running on it and the dialog is still on top. I am guessing it is somewhere in the Mate desktop but I have no idea if/how it can be restricted to its own workspace only.

Any suggestions?

TIA,
