Google Sync is not supported at the moment. I need to understand how this works 
first.

What do you mean with "all of my scripts were gone"? The scripts that were 
installed locally?

At the moment it is not possible that local scripts are deleted by the remove 
storage. The Import Mode at the settings page can either be "Create only" or 
"Off".

What I meant is that when I reinstalled Chrome, all of my scripts were gone and 
I was just hoping they would stay with Google Sync, but I know how difficult 
that may be to do. Where are the scripts located in the Google Chrome folder 
and I can go grab them again.

You can copy the database files from the old to the new profile.

Ok, so this is not really an issue right? It is more a enhancement request. :)

That didn't work for me. There's just a file with the number 2 in there. I 
tried replacing it and got nothing.

I haven't tested this yet, but I think it should work when you replace the file 
of the new profile folder with the old one. 

The file you have seen is numbered by Chrome. It increases this number for 
every extension that creates a database to store some data. That's why the 
number of the TM config db might be different in your two profiles.

You can take a look into the database with sqlite.

For your problem the probably most easy solution is to backup and remove the 
new profile folder and copy the old one back. If there are other extensions or 
settings you don't want or need, you can start Chrome and export you scripts 
from TM at the options page. After this you can restore the backup and 
re-import the scripts. 

This did work for me, I just had to restart Chrome! Does this keep the settings 
as well? Also, can you place it in a different location? Say Dropbox, to keep 
scripts in Sync (similar to Chrome Sync).

Sync server now is bumped to version 2. You can select the server at the TM 
options page. Version 1 seems to have issues, when the user's DB size reaches 
5-6 MB.

I'm on 2.6.2767 and I don't see it. Where is it again?

You don't see what? Do you mean your scripts are gone or are you searching for 
the sync server setting?

Did you already set the sync server to version 2?
As I wrote sync server version 1 may forget the stored scripts in case the 
amount of data reaches 5-6 MB.

I don't see the sync server setting at all. There's no option for it in the 
menu anywhere.

Sorry for my late reply. Please set the "Config Mode" to "Advanced".

Thanks, I got it working! Question, how often does it sync? Also, how do you 
get a newly installed script to enable sync by default? Lastly, does it sync 
changes, like if I were to modify a script?

Now all you need is the ability to sync your installed Tapermonkey scripts with 
Userscripts.org favorite scripts!

Oh and does it sync tapermonkey settings as well or just what scripts are 
installed?

* How often does it sync?
TM syncs:
1) before every TM update check
2) whan a script is changed locally
3) when TM starts
4) every 5h (will become configurable)

* Also, how do you get a newly installed script to enable sync by default?
not possible atm

* Lastly, does it sync changes, like if I were to modify a script?
Of course.

* Oh and does it sync tapermonkey settings as well or just what scripts are 
installed?
Only the scripts and their install URL.

* Now all you need is the ability to sync your installed Tapermonkey scripts 
with Userscripts.org favorite scripts!

I'll check how this could work, but not all scripts are necessarily from 
userscripts.org.

Awesome, thanks for the info! It's working great! You've helped out a bunch!

Google Sync now is supported:

Would love to be able to sync the data my userscripts store as well, that'd be 
epic!

This is not easy to implement, but maybe I can use Google Drive for this. I 
have seen other scripts that do it this way, i.e. the sync plugin of

Could you please create a new issue in order to track this and to keep you up 
to date on this? Thanks. :)
