I think the behavior should be reversed in this case.

Hi,
Thanks for reporting this issue.

I tried to reproduce it on my computer but was unable to, so was hoping you could answer some questions for me, please:

• Does the bug happen with the latest Nightly?
• Does the bug happen when running in Safe Mode?
• Does the bug happen in competing browsers?
• Does the bug happen using other Firefox versions?
• Does the bug happen on any other webpages?

If you could get back to me with those details, I can then try again to reproduce the issue.

Thanks

If i uncheck the "float: left" from the css: 'body > .container .content, body > .container .sidebar { float: left; }' Is working good.

Right, this is an old known issue with selection over out-of-flow boxes, like float and abs.pos. boxes.
