Yes, I wil try it with the profiles.
Whereto do I have to copy the portable Firefox, portable Thunderbird, etc., my own Data to Linux on the USB-Stick? I had created a folder there but I cannot find it within Linux.
Yes, I will do so after I know which distro works fine for me. But since Linux is loaded to the RAM it should be very fast, if I understood it right.
And to not to have to press F11 or another key to show the boot menu each time I start the Notebook I have to set in the BIOS the USB port to be booted from?
Assuming the portable is configured the same for profiles, and I think it is ......several ways to access the profiles in Firefox are:
A.
1. Open the working Firefox 'Help' menu and click 'Troubleshooting Information'
2. A page opens with a blue menu. Beside 'Profile Directory' click on 'open directory'
3.Save the info.
4. Open new Firefox same way.
Delete contents of the 'open directory' and paste in saved info from the working FF.
B. Click on the 3 hash marks in the upper right hand corner of the FF window.
For what ever reason, I no longer see 'troubleshooting Information' there since going with FF v57.
Either way, be sure to double check 'preferences' in the 'edit' menu. I've found that not all the profile is carried over.
As to 'speed', the 'fastest' in booting will be from a SSD.
Booting from a USB drive is faster than from a DVD.
The 'fastest in operation' will be the Puppy version on a DVD because all of the distro is copied into ram.
An SSD is not faster than ram. Any installed app that is opened is first copied to ram, then opened in ram. Puppy on a DVD skips that first step. It's already in ram.
On USB flash drives, though, installed apps often originate from the USB and copied into ram where they are opened. So opening an app is going to be slower.
But once in ram, an app is going to only run as fast as ram allows .....unless it has to make calls back to the hard drive/SSD.
And this is where Puppy on a DVD can really kick but. The call is made to ram, the fastest source in the computer.
Puppy on a DVD may boot slower, but an application's going to function fast.
If you are curious. Setup a Puppy DVD and a USB version, the same content. You'll notice Firefox opens slightly slower from a USB flash drive than the DVD, but feels identical in usage.
I started out with the Puppy Live DVD but have grown to like the USB version a bit more as I understand it better.
Personally, I'm not a fan of dual booting. I've seen users have problems and I don't like spending time troubleshooting and/or having to re-install because of problems.
I have tried out Virtual Box on a Windows platform and run Linux virtually. I had no issues.There was no possible interference to booting Windows. Mint was the very first I tried out that way and it was relatively easy and safe.
I'm not familiar with your bios.
I have an old Toshiba laptop from the Pentium 4 era, that had no permanent boot selection and I had to use an F key on boot every time I wanted to change boot order. grrr.
If you have the option to change boot order, it will be in your bios. It's probably there.
Often the 'delete' key or the 'F10' key , on boot will open the bios. From there it's simply menus.
