Most of times (when I need it faster of course) selection with mouse goes grey as if I am switching window or frame in the webpage. 
Because of this I cannot simply use the keyboard Ctrl-C for copying, but I need per force use the right click(selection then goes blue again) and select copy, which is much slower!!

Reproducible: Sometimes

Steps to Reproduce:
1. Select text in htlm page, expecially if starting with a double click on a word and then keep dragging.
2.
3.
Actual Results:  
Text initially selected in blue goes grey(selected, but not focused) even if I haven't yet finished to select the same line.

Expected Results:  
Text stay selected in blue(focused)

I have many add-ons.

Actually even the PgUp and PgDn don't work as well, really like if I am inside another phantom window...the weird thing is that this happens while I am selecting the text, so I am still working on that same window...How can it lose the focus like this?

This behavious is due to a bug in the "Reframe It" add-on.
