This time I have a question to which maybe some of you may find trivial (hopefully!).

I'm running Firefox 30.0 in Kubuntu 14.04 (fresh install) and I'm having a weird problem, in some sites some symbols/logos/icons are showing terrible wrong

I'm suspecting something related to encoding but I'm not really sure.

I hope some of you have some ideas to fix this.

The icons look like this:

and should look like this:

Could you please include the link. Also a screen shot, showing how wrong it is, would give a representation what issue you are talking about. – Ruslan Gerasimov Jun 23 '14 at 5:28

Those are likely text icons using @font-face embedded fonts instead of images - have you tried disabling the extensions in Firefox? (half of mine block things like this (as well as ads - intentionally)) – Wilf Jun 23 '14 at 5:35
Thanks @Wilf I've just did that (disable all add-ons) given you recommendation and restarted FF, the page still looks the same. – felipunk Jun 23 '14 at 5:40

You should check

Preferences > Options > Content : Fonts & Colors > Advanced: [X] "Allow pages to choose their own fonts, instead of my selections above"

There is a preferences setting you may need to get the fonts to work.

Go to 'Preferences' > 'Content', then under 'Fonts & Colours' click 'Advanced' - enable 'Allow pages to pick their own fonts', close the settings and reload the page.
