I'm experiencing the same problem too. I'm using the latest version 39.0.2256.71 on windows 10 and it generally happens if I have a few javascript-heavy tabs open (facebook, gmail, etc) so it looks like it might be a memory leak of some kind?

I have already turned off mouse gestures, and the problems persists. Not had this problem with Chrome which I recently switched from, but I'm seriously considering switching back to chrome because I am losing work.

I used to be a Google Chrome user, but since chrome changed their browser to prevent the backspace button from being used to navigate back to the previous page, I decided to swap to opera which does allow this - so I swapped to opera, configured the backspace for the navigate back button and all was fine for a couple of months. However, since the last update, whenever I type a url in the location bar and press the back button to correct it, this activates the keyboard shortcut to go to the previous page which makes it very difficult to use. This did not happen prior to version 40 release. please fix or tell me how I can prevent keyboard shortcuts from activating when typing in a url.
