Another problem solved
Something plaguing us here on the farm has been our adult autistic son installing Windows software to his Linux computer.
Because he is so skilled in the original Windows Paint software, we have WINE installed on his Linux Mint computers so he can run Paint. The trouble with this arrangement is that even though he only has user access to his Linux desktop, he can still install Windows software under WINE.
No amount of research, permission changes etcetera on may part could prevent this from happening. I was constantly going in at night and uninstalling things like YouTube downloaders, questionable tool bars full of malware and other nonsense. My son was also installing about every Firefox extension he stumbled upon. There were 20 different video downloaders alone, and dozens of other bits and bobs.
Then this week, I stumbled upon Public Fox
This Firefox add on, allows you to really lock down Firefox. Locking users out of the ability to add or change other Firefox add ons, locking out the about:cong, history saving, and most all the other Firefox preferences!
Best of all, this add on will allow you to block the downloading of any file type you wish, simply by entering the banned extension!
Files ending in .zip .exe .com .bat .pdf now all blocked from even being downloaded. He can’t install a Windows program, if he can’t download it!
Further, you can specify web sites that you wish to block. Yes, I block many sites in my router, but my crafty son figured out that he could go to the secure version of a site and bypass the router’s ability to block it! This has been a real problem lately, as he’d do a web search for a favorite cartoon character, and end up on a secure porn site that my router couldn’t block.
Using the features in Public Fox, I can block for instance, all .xxx sites, all sites with certain key words, along with my extensive list of sites I’ve compiled that I don’t want him on.
Installation is as easy as other add ons. Just search for it by name, install it, then click on Preferences and set it how you want it.
Then set the password for Public Fox. This way any changes to Firefox preferences and add ons will be locked tight!
There are some reviews that state that this extension no longer works in Firefox. Further that it is serving up adds on its own. All I can say, is that running under Linux, using Firefox version 49, it seems to do exactly what it is supposed to do, and I am not getting any adds from it, though one of my other extensions is AdBlock Plus.
