You still can save files inside /mnt/home. Do it like this:
Create a new directory:
| Code: | | # mkdir -p /mnt/home/spotfiles |
Make spot the owner of that directory:
| Code: | | # chown -R /mnt/home/spotfiles |
Now you can download files with the browser, browse to /mnt/home/spotfiles and save the files there when prompted for a download location.

Thanks rcrsn51, Micko, Luluc all of you
My question is:
I have saved the following text and promised myself to test it out but I am so afraid of failure so I have postponed it the whole day. Can you guys confirm it is good advices. Apology to the author L18L that I failed to remember that you told me how to.

Edited: but more important is to change root's password Exclamation
by simply typing in a console
Code:
passwd
Running FF as spot
It's not hard to run Firefox or SeaMonkey as Spot, I just demonstrated how in a different thread.
Boot puppy normally.
Open the terminal.
enter "su spot" (no quotes) at the prompt.
enter "firefox" (no quotes) next.
When it launches, Firefox will be running under user Spot.

Note, starting from default browser icon you are root.
dragging defaultbrowser.desktop to the desktop and then klicking that will start defaultbrowser as user spot.

Hi guys,
@ nooby - rscrn51 is saying that I was actually running Firefox as spot (even though it seemed (to me) I was running as root).
@ rcrsn51 - I have now tried two downloads and so I can personally confirm what you already knew and advised.
It is rare (perhaps the first time) that I have used large and emboldened text - but I was worried for other users (though I did say "presumably" as I'm only too aware I'm not all-knowing).
So now, thanks to you, I have a hugely improved understanding and confidence that browsesafe works.
My big, big mistake was in thinking that "whoami" would return my Firefox status. My apology for that and, with hindsight, for raising my query so strongly.
@ 01micko - thank you also for your pet and your help.
My regards

rcrsn51 thanks for that one. Most instructive. The problem is that I have deleted .mozilla from root and reuse an old .mozilla that I placed in mnt/home and it would fail to link to that one from this new dir you made.
One would need to do what? Copy over a copy of that old one into that dir then?
Ahh now I get it "browsesafe " is a script or pet that Micko has made?

Hi nooby,
Go to opening item in this thread and install browsesafe-0.5.pet and chose the icon option during installation.

There are two problems that we are trying to resolve:
1. Run the web browser as an unprivileged user for security reasons.
2. Keep the browser's profile and any downloaded content outside of the user's savefile.
Try this. It assumes that your Puppy installation has a /mnt/home folder AND it is formatted with a Linux file system like ext.
| Code: | | adduser -h /mnt/home/bsafe bsafe |
If you have a full install, use something like
| Code: | | adduser -h /mnt/sda1/bsafe bsafe |
Then run your browser with
| Code: | | su -c YOURBROWSER bsafe |
This will automatically create a .mozilla profile in the new home directory. No symlinking is required. The default download folder is in the bsafe user's home directory outside of the savefile.

What do you mean by "fail to link"?
Whenever you link something, remember that the link points to a file or directory that has its own permissions. In other words, if you just link /root/.mozilla to /root/spot/.mozilla, the second one is just a link, the permissions on the first one are still in force, and those do not allow spot to use /root/.mozilla. In such circumstances, Firefox will probably choke and panic when run as spot.
It's more feasible to do the opposite: move .mozilla from /root/ to /root/spot, then make spot the owner of /root/spot/.mozilla, then link /root/spot/.mozilla to /root/.mozilla. That way, when root runs Firefox, the config files will belong to spot, but root can still use them because root can do everything. However, if root creates any new file or directory there, it will be owned by root and forbidden for spot. So linking .mozilla is generally a bad idea, too prone to errors. Ideally, only run the browser as spot, never run it as root.

Thanks Luluc.
Well I have the profile on mnt/home so I need then to move that one to spot.

Go to your /mnt/home folder. Is there a subfolder named 'spot'?
Check its ownership. Does it belong to user spot?

oops sorry I did have a dir spot there and I did look at permissions and it seems to be owned by the whole world. But I had not read your post then and was looking for bsafe and that one was no where to be found so I deleted the spot dir and wanted to start all over.
How does one see if it is owned only by spot. Every box was filled in it.
When I tried to do the bsafe it did look like it worked but none such could be found
Ahh I should have done this one?

Clearly, you don't want to save lots of files in spot because it fills up your savefile. So go to /mnt/home and make a folder called "spot-download". Give its ownership to spot
Code:
chown spot:spot /mnt/home/spot-download
Now you have a better place to download files. Of course, this folder is now theoretically vulnerable to attack.
/quote
But if it is vulnerable to attack then what is the usage? I mean that was why we wanted to be spot in the first place To get away from such vulner things

Are you confirming that something worked? For the sake of other readers, please explain.

Sorry, there was this forum bug again (spaces in URL)

I did not install the pet just applied seaside's advice in http://murga-linux.com/puppy/viewtopic.php?p=516037
EDIT
nooby,
don't worry, this time it was me who was confusing
Edit
And I did not try to use root's bookmarks

Sorry for all the confusion. I have collected things about it and my ADHD makes it impossible for me to add everything because then it just blur out. So I forget to add in sources and links and whome wrote what.
Back on topic.
Browse as Spot.
Yes I want to but I also want to use the prefs I have already set up.
Okay Luluc seems to describe how that is possible. By doing thing in right sequence the owner of the prefs will be spot and the .mozilla placed in that spot directory that is password protected and root has a new password too
and the big problem is that I should not ever run root there to change something. Only use spot apart from using root to move pictures out to mnt/home if I want to keep them also for root to look at when not logged in as spot?
The problem for me is that I do want to use the browser as root.
So I need to reboot into a clone that is root then? Or maybe have one browser like FF3.6.16 as owned by root and one FF4.0 as owned by Spot?
