Chrome and Chromium both frequently freezing on a fresh Ubuntu Gnome 13.10 install

I recently installed Ubuntu Gnome 13.10

Since then i experience a lot of issues both with chromium and google-chrome-stable. At about every 3rd launch I get the message 'couldn't log in properly'. But then it works fine.

After some minutes of usage some pages suddenly load very slow (especially Facebook) and while its loading I can not scroll or do anything in any tab (although i can switch tabs). After some more time it freezes completely and i need to force quit. (This happens regardless whether the message mentioned before appears or not). Sometimes also the 'Save Image as' won't work at all, even after a fresh start.

Here's what I've done so far:

• Multiple remove/install (using apt-get purge and removing ~/.config/chromium resp. ~/.config/google-chrome

• Disable all add-ons

• Clear Cache/Cookies

• launch chrome with logging (see below)

• Check memory: Theres always about 2 GB of RAM left when the freezes occur

The Gtk-Warning appears many times before the crash, so I think it is not the matter. I'm also confused by the message about the Autofill, since i wasn't using any site requiring Autofill at the time when i logged that crash.

I'd be very glad if anybody could provide me with some ideas how I can further troubleshoot the problem.

Run this in your terminal.

echo on | sudo tee /sys/class/net/eth0/device/power/control

This should definitely solve most network-related problem...after its done, exit sudo and pull the ethernet cable or disconnect from any network you are connected to, then logout, and then login and connect. All your browsers should be working, and you wont face any network disconnections.

Try this:

• logout google acc
• go to settings
• go to advanced sync option and uncheck autofill & passwords
