possible.<br><br>I don't possess the necessary Bugzilla skills to file this
properly, <br>but I think I shall post a comment on bug 1315144 to alert <br>the

<br><br>==============================<wbr>====<br>A personal note: <br><br>This is
probably gonna be one of the last bugs I file; <br>I am currently full of
resentment and bitterness against <br>Mozilla, who decided to copycat Google and
put Vista <br>on the same sinking boat as the much older XP. <br>I have been
following Firefox's development in the <br>Nightly Channel (in this Vista SP2
old laptop) since <br>v23.0a1 (buildID=20130424030917 still on disk..);
<br>countless daily threads read over at the mozillazine <br>Firefox Builds
forum, also countless Bugzilla bugs read, <br>so it now kind of pains me to not
be able to continue...<br><br>Installing Win7 on this old laptop or switching
over to Linux is, <br>at least for now, out of the picture... But the Mozilla
Foundation <br>said, among other things, that they could not afford <br>(them
being a multinational enterprise) the heavy cost <br>of maintaining Vista
support any longer; they know better; <br>but, likewise, I can't currently
afford the "heavy cost" of <br>buying a new laptop (probably with Win10 that I
dislike...) <br>to continue Nightly testing...<br>So, to recap, 2 more weeks of
52.0a2 testing, one <br>cycle of 52.0b testing and several months frozen on
<br>52.0ESR (with no testing there...) - and we Vista users <br>should be
thankful for that, too, because we were not <br>cut-off altogether... Such is
life...</font></div>
