In the Contents box at the top of a Wikipedia article--broken down into various headings and sub-headings--I have been noticing recently (within last few months) an increasingly recurring problem. Normally, when clicking on one of these headings (for instance: 2.1 Background), you are automatically brought down to that specific section within the page; now, for as long as I have been using Wikipedia, after having arrived at this lower section, it was always possible to click on the "Back" button at the top of the browser window and this would send you right back to the Contents box at top of the article from which you had initially clicked.  However, it seems more and more I have been navigating articles in which this helpful feature is disabled/glitching/never installed in the first place. The "Back" button is not available, i.e. gray and non-clickable.  It's not every article, or even every linked-heading within one of the malfunctioning articles, nor do I come across it in the majority of articles I browse.  

Sometimes, the issue lies in the in-line citation footnote (the super-script number which brings you down to the corresponding Reference section); once clicking the super-script footnote and having arrived at the Reference section, I find myself no longer able to return to the specific place within the article from which I had originally clicked on the footnote.

The most recent manifestation of this problem which I have come across is on the "George MacDonald" article (the fantasy writer).  In this instance, the linked headings in the Contents box function properly, while the in-line footnotes are at issue.  I find this to be the case in the very first footnote (#1), which will take you down to the Reference section but will not allow you back through hitting the "Back" button.  However, the second footnote works just fine...

This isn't a huge problem, obviously, and one can live without it; however, especially on very long articles, I find this a very convenient feature...just one more nicely designed Wiki-feature.  Also, I am no programmer or engineer, so perhaps the issue is somehow on my end; or perhaps a slip-up of the author who created the page in the first place.  If the latter, should I therefore be bringing this up on the individual article's Discussion page? If the former, I'd be happy for any advice or criticism.

I hope I have posted this in the correct place. I scoured Wikipedia's help-sections (Wikipedia:Questions; Help Desk; Village Pump) previous to this and here seemed to be the only applicable forum for this comment.  

Well, thank you for your patience. Obviously this is not a pressing glitch...I merely thought I'd bring it to someone's attentions, if no one else already had.
