I want to use Google Chrome Portable from a locked, write-only partition on a USB stick. However, an error message says this can only be done if the user allows writing to a temporary file on the host computer. I do not want to do that. Is there a way to change configuration or other files to allow such use?
As already answered with regards to Firefox, you can not. You'd need to recompile the app to permit it. Which means you'd need to change the code of the app itself and compile your own special version. As far as I know, running entirely read-only with no writeable area is not on the radar of a needed feature for any of the development teams for the major browsers.
Sometimes, the impossible can become possible, if you're awesome!
How about to other browsers like google chrome? safari?
