Update to TOR Browser 5.0

Hi all,
I have a problem with update to TOR Browser 5.0 on SO win10.

Automatic update that generated this error:

XML Parsing Error: undefined entity
Location: chrome://browser/content/browser.xul
Line Number 1401, Column 11: <toolbarbutton id="PanelUI-quit"

I'll be grateful for any help

So, you all day I try a solution and it seems that the best thing is to reinstall the browser.
In any case, I downloaded whonix + virtualbox ... Win 10 does not seem to get along with TOR

Thank you all

I have the same error after update. Connects to Tor network, then browser window says this:

XML Parsing Error: undefined entity
Location: chrome://browser/content/browser.xul
Line Number 1401, Column 11: <toolbarbutton id="PanelUI-quit"

What is the solution please?

I suspect you updated by virtue of a messagebox appearing when you used previous TOR. Go to Torproject.org and download version 5.0, rename the original TOR folder/directory to something else then run the new download. It should work then.
You will need to keep the original places.sqlite and copy into the new profile in order to retain any bookmark menu items. You will also need to keep your bookmarks file in order to run the new 'opening page' if you have one.
