Google Chrome

revised 3/6/13

I have come to rely on bookmarks and open tabs.  I have been baking up my bookmarks for some time, both as part of routine disk images and as a separate procedure when it seems appropriate. I have felt this requirement partially because I am still unclear on sync issues which could mess up my bookmarks.

Tabs
Although previously never a problem, for an unknown reason Chrome recently “lost” about 20 open tabs, which I could not get back using Ctrl+Shift+T.  It appears I am not alone in this experience.

What I should have done (determined by looking at how the files behave):  closed Chrome, copied Last Session and renamed to Current Session.  Then when I reopened Chrome I would at least have had the tabs as they existed at the beginning of the problem session.

The way it seems to work:
-         when open a session, what was Current Session becomes Last Session
-         then when make the first change to tabs, what was Curent Tabs becomes Last Tabs

Bookmarks
I had not used by netbook in several weeks and was afraid that its "old" bookmarks would replace the current ones from my G1 pc.  I was out of town and therefore unable to recover from a problem, so before opening Chrome on the netbook, I renamed Bookmarks and Bookmarks.bak.  This worked as expected, new files were created and synced.  Everything may have been fine if I had not done this, but I'm not sure.

The way it seems to work:
-       when change a bookmark, Bookmarks file is changed
-    Bookmarks.bak file is updated when ?????????????????

(3/5/13) Bookmarks sync is a little flakey.  Last night I had added bookmarks and renamed a folder.  I then booted from a different drive.  The added bookmarks were there, but the folder was not renamed.  After booting this morning, the new folder name was there.  Question: would the folder name have changed if I had left the system on overnight?  I also should have looked at the folder name last night using another PC.

Flash (2/22/13)
Was getting Adobe Flash Player update notification upon boot, but Google and Adobe both say "updates for Adobe Flash Player are automatically included in Chrome system updates".  After an update, about:plugins (link doesn't work) and adobe.com both show my installed version number (11.6.602.171) to be higher than the latest Player version listed in the table on the above Adobe web page (11.6.602.167).  It is also interesting that add/remove programs shows version 11.1.102.55, which is not listed in about:plugins.

Extensions (2/23/13)
Chrome version 25 automatically disabled AVG Safe Search and provided this explanation

Java (3/6/13)
I disabled Java a couple of months ago due to the various security warnings.  This has caused no problems, so I should probably go ahead and uninstall it from all boot partitions (old Version 6 Update 37 is currently installed).  Note Java is not installed on B2 (Ethel's), B3 (HTPC), or NB205 (Win 8 install)
