translucent rectangle in top left corner when opening firefox

Posted

when first opening Firefox a small translucent rectangle approx 3cm x2cm appears in the top left corner it then immediately disapears

could this be a tracker?

I have googled to no effect disabling Addons then restarting doesn't work, and i cant find out how to disable hardware accelerator. I have completely reinstalled the os I have three on separate partitions I'm using ubuntu11.10 Atm but this happens on all my linux os' I haven't checked windows yet though any advise would be welcome.

Chosen solution

Hi.

I also want to join this conversation, because I also see this translucent rectangle then firefox starts. I have Firefox 16.0 on virtual machine and it doesn't exhibit this behaviour. I am sure this is not a bug, but it looks ugly. Firefox is very good browser and should show its main window immediately.

Thanks

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.

To Reset Firefox do the following:

  1. Go to Firefox > Help > Troubleshooting Information.
  2. Click the "Reset Firefox" button.
  3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
  4. Firefox will open with all factory defaults applied.


Further information can be found in the Reset Firefox – easily fix most problems article.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe mode start window or otherwise make changes.

You can also check for problems with the localstore.rdf file.
