I dont know how it came there but looks totally wired, I have the same problem with other sites too.
Is this known problem ?
The red boxes with borders are there since yesterday night, I guess right before I updated the FireFox to latest version.
What could be the problem ?

Everything looks like shit, please help asap.

Most likely an addon? Check it.

Tried it too.
I have started firefox in safe mode, reverted everything to defaults.
No addons, default preferences and it was still there.

Even check my PC with Kaspersky Security, it's clean.
Everything looks like shit. Dunno what to do.

red means no-follow link you must have installed some seo-plugin

I was observing the html source code and noticed the same.
There was addon name Search Status installed and it was casing the problem, though i didnt catch it when tried it for first time but it's working fine now.

@nba517: Just saw your post after fixing it, though 1000ds of thx for both of you to help <3

Edit:
It was Quirk Search Status feature and by mistake I enabled it.

There is an option to disable that only option in the addon.
