I recently switched operating systems from W11 to Linux (Zorin), and installed a new copy of Firefox. I rely on local web pages I have written for some of my work, but the new copy of Firefox does not find the file. For example, when accessing an image, e.g., file:///magrathea/dmpase/home/index/coastal24.png, Firefox gives the message: File not found Firefox can’t connect to the server at local file What can you do about it? Check to make sure you’ve typed the website address correctly. The address is correct, that is, the file resides at: /magrathea/dmpase/home/index/coastal24.png and the user does have permissions to read the file. I've tried adding up to five '/' characters to the beginning, and I have turned off all of my installed add-ons, but without success. An apparently related problem is that double clicking on a '.htm' file also changes the address, for example, from '/home/dmpase/Desktop/index.htm' to 'file:///run/user/1000/doc/f07a8988/index.htm' And finally, the "Brave" browser is able to read the files with no errors. How do I fix this for Firefox?
