Unexplained data consumption by Opera

  • Hi, i am using Opera on Windows 7 desktop, for the past few days Opera has been consuming unaccounted for 500-700 MB of my limited bandwidth.

    I can't pinpoint for what, how and why is it consuming so much data and how to stop it.

    I am using the following extensions - AdblockPlus, CopyAllurls, Download Chrome Extension, FVD video downloader and Web of Trust.

    Any help would be greatly appreciated.

    I pinpointed that it is Opera using Glasswire network monitoring tool.

    Thank You.

  • Does Opera internal Task Manager (from Developer menu) display any network activity?
    Another check - if you rename opera_autoupdate.exe in opera folder into something other, will network traffic continue?

  • I did not know about the task manager, will check it out now. Have not renamed auto_update.exe,yet

    How do i disable opera auto update?

    Is there an Opera/Chrome addon that monitors bandwidth usage by addons, websites?

    I have disabled FVD video downloader and monitoring bandwidth usage glasswire, so far usage is normal.

    Thank you

    Renaming auto_update.exe is one way.

    The same internal task manager measures many parameters (incl CPU and netowrk usage) by tabs and extensions - just what you asked 🙂
