Internet Apps Support

I have Google Chrome (48.0.2564.116) Portable installed, and I use it on Windows XP. This is the most current version which works on Win XP, so I cannot update to the latest version (or any version newer than 48.0.2564.116).

QUESTION 1:

As of a couple of days ago, every time I start up Chrome, it gives me a popup windows saying,

Your preferences can not be read.
Some features may be unavailable and changes to preferences won't be saved.

I have got a detection from Avira Antivirus during instalaltion of Opera Portable. I uninstalled it.

I guess it's not a virus but ad-ware or something. Nonetheless Microsoft System Center Endpoint Protection removes the FileZilla files and flags it as
"PUA:Win32/FusionCore". Even if it's a false positive, this makes this portable app unusable and not very portable. Earlier versions of FileZilla were fine.

You have 222e454a3f85749b3af06943524d90a6 listed as the hash for Lynx Portable 2.8.9 but I'm getting 00f7be845016223ac53d62572689e309. Downloaded twice to be sure.

This new version does not work well on windows 8.1 64 bit
it said it was not responding
and had to close it through task manager
reinstalled it 3 times and in order to do so you had to reboot your computer
the folder would not delete unless you did so
reinstalled the old one and its fine.

I had Chrome portable all set up and working beautifully on my thumb drive, with all extensions functioning optimally.

Then yesterday when it opened it said an update was available. I didn't see any harm in updating it since I had installed it only two weeks ago. However the result was disastrous. It basically stopped working for me; namely, pages took FOREVER to load.

"Chrome Portable" looses all "extensions" when started on another machine.

A PITA really.

And if I just accepted that, and reinstalled all my extensions that I need again and again ...
... I suppose that also wastes a lot of disk space, right?
Because the extensions disappear from the browser, but probably not from the disk, right?

So:

How to clean up the extensions diskspace when ChromePortable has f**ked up, and lost all its extensions, just because I plugged in the USB stick into another computer?

Thanks a lot!

Is there any way to maintain my Google login (among others) on Chrome while using it on different computers? I use Chrome portable via a USB drive because I regularly have to switch workstations over the course of my day at my job. I use Chrome portable so I do not have an instance of Chrome with my personal info on every computer. However, each time I open it on a different computer, I have to login to Chrome and to a few other extensions (notably, LastPass) each time.

I've been a Chrome Portable user for years.

FYI only. Win 10 64 bit Environment. Version 67 installed with no errors.

when running the application, the error message
