Hello, 

I can't explain why, and I cant' reproduce the problem, but yesterday evening, my firefox started displaying the Visual Tab Switcher when I accidentally used the keyboard shortcut control-shift-ab.

Control-tab triggered normal tab switching, it was indeed control-shift-tab that ran the visual switcher.

And I had NOT performed the about:config  -- browser.ctrlTab.previews change, I learned about it later on, trying to figure out what had happened. I can be absolutely positive nobody had had the opportunity to change it for me either.

I remember having twitter, lemonde.fr and hotfile.com among my open tabs.

Here's for the bug report, this may look strange, but I report things as they were.

Reproducible: Couldn't Reproduce

Steps to Reproduce:
1. control-shift-tab keyboard shortcut. I couldn't reproduce the problem.
2.
3.
Actual Results:  
couldn't reproduce it.

Expected Results:  
couldn't reproduce it.

Below are local details from the about:support page.
