[FAQ] How do I reset flags if Opera doesn't start / display correctly

  • We all love experimenting, but sometimes flags may bite (as stated in Opera).
    If they do, that's how you recover:

    1. start Opera with --no-experiments command line parameter
      (for those of you who don't know how to do that have a look here)
    2. go to opera:flags and reset them or try finding the culprit manually

    I hope this is helpful to you 🙂

  • Thank you that helped me

  • Helpful, too! 😉

    After updating to Opera 29.0.1785.0 some pages are displayed "minimized" (showing the whole page in the browser window; but my zoom setting was set to 100%) — and I didn't know which changed flag could be reason for this behaviour (not occured in the previous developer version!)

  • Updated opera, now it wont load, the flag above doesn't work for me I'm stuck in a crash loop (It starts, freezes, closes and repeats x3)

    My session.db was deleted. now i have tabs and no browser. reinstallation did not work.

  • I am having the same problem aemalakai. I updated to Beta 32, opera starts, white screen, closes. I have uninstalled and completely reinstalled, also I did a clean install, and nothing seems to be working. Opera 31 stable opens and runs fine. Any ideas?
