Hi, this is just as a heads-up - I have no idea whether this is something the forum admins can do anything about. Yesterday, the PC forums suddenly started to look weird in Firefox: the navigation bars at the top were displayed as a list of text options (see attached screenshot). The issue still persists.

Apparently this was caused by some kind of conflict with the AdBlock Plus add-on for Firefox. I solved it by disabling ABP for this site, which is easy enough since there are no ads here anyway, but I wanted to post it here to make you aware of it. I don't think it was anything that changed with the add-on, because it says that the last update of ABP was on Jan 16.
