Can't open any webpage, opening new tab doesn't allow webpage.

Posted

Can't open any webpage, opening new tab doesn't allow webpage. Have uninstalled firefox, refreshed it but nothing changed. Found an advise to download and run mozregression-gui.exe and I did it. This is a result of that scan: platform: Windows-7-6.1.7601-SP1 python: 2.7.11 FROZEN (32bit) mozregui: 0.9.2 mozregression: 2.3.2 message: IndexError: list index out of range traceback: File ".\mozregui\bisection.py", line 72, in bisect_further File "..\mozregression\bisector.py", line 561, in bisect File "..\mozregression\build_range.py", line 293, in range_for_inbounds File "..\mozregression\build_range.py", line 198, in check_expand File "..\mozregression\build_range.py", line 238, in get_future

Hi noran3001, sorry to hear about this problem.

It looks like every version tested in mozregression ran normally on your system. Is that what you saw?

Compatibility Mode Problem in Firefox 73

Could you double-check that your regular installation of Firefox is not set to run in backwards compatibility mode? Here's how:

Find the icon you use to start Firefox, and either:

  • Right-click a desktop shortcut, then click Properties
  • Right-click a Firefox icon pinned to the Taskbar then right-click Mozilla Firefox, then click Properties

You should clear all the boxes on the Compatibility tab for best results (giant screenshot below).

Any difference the next time you start Firefox?
