In Use. Support LAZY load of session. Support AUTOSAVE, but NOT to user saved sesssion (so when closing a session we want to keep, existing session must be replaced). DOES NOT save HISTORY.

To try. Seem to provide simple session management feature in addition to suspend tabs.

Fix ZScaler authentication - import ZScaler SSO cookie

ZScaler is a corporate filtering proxy. Users must login with Single-Sign-On to get access to internet resources. If authentication fails in Chrome but, say, works in Internet Explorer, one can import the authentication cookie in Chrome/Chromium and hence skip the failing authentication step (from calebcoffie.com).

• First, go to C:\Users\%username%\AppData\Local\Microsoft\Windows\Temporary Internet Files, and locate the zscaler cookie, which is named cookie:%username%@gateway.zscaler.net.
• Open the cookie in WordPad (or copy/paste into WordPad). You should have something like this, where the XXXXXXXXXXXXXXXXXXX are the actual cookie (secret) value:

_sm_au_c
XXXXXXXXXXXXXXXXXXX
gateway.zscaler.net/
...
...
...
*
_sm_up_c
XXXXXXXXXXXXX
gateway.zscaler.net/
...
...
...

• In Chrome, create a new cookie using extension EditThisCookie, and import both cookies above using the templates below, where the cookie value must be replaced with the one found above:

{ "domain": ".gateway.zscaler.net", "hostOnly": false, "httpOnly": false, "name": "_sm_au_c", "path": "/", "secure": true, "session": true, "storeId": "0", "value": "XXXXXXXXXXXXXXXXX", "id": 1 }

{ "domain": ".gateway.zscaler.net", "hostOnly": false, "httpOnly": false, "name": "_sm_up_c", "path": "/", "secure": true, "session": true, "storeId": "0", "value": "XXXXXXXXXXXX", "id": 1 }

Troubleshooting

chromium: Blank window when used over ssh tunnel

When opening chromium through a ssh tunnel, the application opens but all pages are blank.

The problem is apparently linked to a broken MIT-SHM detection code [2]. Download the fix from this link or this archive, then compile and load it:

cc -shared -o XlibNoSHM.so XlibNoSHM.c
LD_PRELOAD='libdl.so ./XlibNoSHM.so' chromium
