18 Very strange!

24 The latest release of Firefox is version 22.0, however version 17 is
25 the latest "Extended Support Release" and coincidentally also the
26 latest stable version in Gentoo. The url "about:" will show the
27 version information in Firefox (and most other browsers). If you want
28 to ensure you are comparing apples to apples, you can download the
29 version 17 ESR Windows installer from:

40 I don't know, but here is what I am thinking:
42 A) Does it do the same if you use a different browser? opera or
43 google-chrome are binaries and don't require any compilation, so they
44 might be fast to emerge if you haven't got any other browsers
45 installed. You could also simply use wget or curl to fetch a copy of
46 the page and look at it in a text editor.
48 If other browsers experience the same thing, go to C)
50 B) I would first try to rule out a configuration or plug-in/add-on
51 causing the issue. On the Firefox "Help" menu there is an option to
52 restart with add-ons disabled. This will restart Firefox in "safe
53 mode". Please be aware that it also gives you an option to "Reset
54 Firefox" -- this will reset it to factory default configuration, while
55 supposedly preserving your personal information. I have not actually
56 tried that so I would backup your profile beforehand just in case it
57 goes off the rails. Once you're in safe mode, simply quitting firefox
58 and reopening it will bring it back to normal mode again.
60 If safe mode doesn't help, I would try creating a new profile. You can
61 do this without any effect on your existing profile. Start firefox
62 from shell prompt by "firefox -P" to launch the profile manager.
63 Alternatively, you could login using a different user on your machine.
65 C) If browser or settings don't make a difference, I would ask if
66 you're using any sort of proxy or ad-blocker/parental control/spam
67 filter on your network. That might be silently altering the pages in
68 an unintended way. Also, some employers, ISPs and governments perform
69 content modification on HTTP requests to insert ads or block
70 disallowed URLs. If your web server supports HTTPS I would try
71 fetching the page using that to see if it is the same. That should
72 eliminate the possibility of outside interference as far as
73 manipulation of the page contents goes.
75 D) If this is a website you created, I would ask if you might have
76 your /etc/hosts file pointing at a different server's IP. I have seen
77 a similar problem where someone had their domain name on their web
78 development laptop pointing to a test server rather than the live
79 public server. That's probably not the case since you've experienced
80 the same problem on your local web server, but I thought I would
81 mention it just in case it might spark any ideas if everything else
82 failed to work.
84 Good luck,
85 Paul
