Browser issues with MediaWiki
From MediaWiki.org
This page was recently moved from MetaWiki.
It probably requires cleanup – please feel free to help out. In addition, some links on the page may be red; respective pages might be found at Meta. Remove this template once cleanup is complete.

This page is intended to document problems with certain web browsers in editing Wikipedia articles. If you have experiences with a specific web browser, please add them here.
Some of these problems may be bugs, some of them may be user interface annoyances, and some of them may result from incorrect or unexpected implementation of certain features on the Wikipedia site. If you find bugs in your browser, this is not the place to report them, but if they are relevant to Wikipedia, they may as well be listed here.

[edit] IE on MacOS 9
Internet Explorer 5 on Mac OS 9 (discontinued and obsolete) displays Wikimedia pages badly, especially quotes.
[edit] Problem with newlines
Some browsers seem to insert newlines into entries. This is likely to be a CR/LF problem (Windows ends lines with CR/LF, Unix only with LF), and to mostly show up during collaborative editing as in Wikis. This problem appears to be solved.
- s/\r\n/\n/sg
[edit] Problems with saving
Internet Explorer 6 deletes any page longer than 32k when saving.
[edit] Problems with editing
When editing, Firefox 2.x changes all non-breakable spaces (code 0xA0) to breakable spaces (code 0x20). This can lead to ugly-looking diff pages. Bugzilla entry. Fixed in 3.0+ versions.
Netscape 4.7/Windows 98
Occasionally refuses to allow insertion into longer articles.
Internet Explorer 5/Mac OS X (and perhaps older?)
Textarea seems to be limited to about 32k; text cannot be inserted into longer pages, instead met with an indignant beep.
K-meleon (Mozilla)/Windows 95
Unicode characters replaced by '?'.
- This happens on any browser that doesn't support unicode.
Note: 32kb limits Textarea was limited to 32kb in both Netscape 3 and MSIE 3, presumably on all platforms for which those browsers were respectively available. In neither case does the browser warn of a buffer overflow. (I am not sure about the version 4 browsers - an experiment might be needed)
[edit] Problems while selecting text
Internet Explorer 6/Windows 98
With Wikipedia Phase II (not Phase III), it's impossible to select part of text on every pages. But there are not problems of selection in input area while editing.
According to the following text this has not been fixed in the Cologne Blue wikipedia "skin". You may like to check if this is your problem before reading any further. MrJones 18:37, 26 Jul 2004 (UTC)
- Check the stylesheet; it may be using absolute positioning on bits where it doesn't really need it. This was discovered and fixed in phase 3 a while ago; the selection bug was triggered by the combination of using absolute positioning for the body text (actually the whole page was in an absolutely positioned div, rather pointless) and fixing the doctype so browsers wouldn't render in quirks mode. --Brion VIBBER 15:41, 5 Sep 2003 (UTC)

- Sorry, I said a mistake ; I have this problem on Meta-Wikipedia too ...But, Meta-Wikipedia use Phase III now ? And I have not this problem on french Wikipedia which use Phase III. Oliezekat 16:13, 5 Sep 2003 (UTC)

- It would really help if when people report bugs, they specify if they're using any non-standard options (such as the Cologne Blue or Nostalgia skins). Cologne Blue skin i still broken in this regard (it's broken in many ways, and no one has yet come forward to fix it). --Brion VIBBER 16:41, 5 Sep 2003 (UTC)

[edit] Meta is in utf8
[edit] Character encoding
The meta wiki is now encoded as Unicode UTF-8 so that it can cleanly include pages and commentary in any language. (Actual display of any given language's characters depends on the fonts installed on your computer, of course!)
Note that some browsers have poor Unicode support and may, in addition to not displaying properly, damage non-ASCII characters during editing. Known problems include:
- Opera 5.0 for Macintosh, and probably other OSs as well. (Opera 6.0 does have Unicode support; if you've used it please say if it works!)
- Opera 6.04 for Windows works well. -- PE 21:50 Nov 15, 2002 (UTC)
- Netscape 4.x
- IE 5.0 (Mac)
Browsers known to be able to view and edit correctly include:
And with appropriate configuration:
- Lynx if Unicode UTF-8 character set is selected in options. Proper display may require setting your terminal for Unicode.
- Links if in graphics mode
[edit] Display problem
My contribution to Wikipedia:Wikipedia_talk:WikiProject Grammar title Display problems with this project page may be relevant here, regarding a possible Mozilla bug.
[edit] Displaying MathML
Few browsers support MathML, and MediaWiki still consider it as an experimental feature. Anyway W3C publishes a list of browsers and of browser plugins and extensions supporting MathML (with relative bugs).
[edit] Language support
There are issues with supporting languages like Lingala. It turns out that at this time Safari provides the best language support. Firefox and Chrome come second and third they show the content properly but not in the edit mode. Internet Explorer did a real poor job in the edit mode showing a character that was not selected.

[edit] Issues when following links with IE 7.0
When opening some articles on http://en.wikipedia.org/, a browser pop-up appears indicating:
File download - Security warning Do you want to save this file or find a program online to open it? Name: Wikipedia_Browser_notes Type: Unknown File Type, 20.4 KB From: en.wikipedia.org
[Find] [Save] [Cancel]
After clicking "Find" the following details appear:
Windows has the following information about this MIME type. This page will help you find software needed to open your file. Windows File Association MIME Type: application/x-gzip-compressed Description: UnKnown Windows does not recognize this MIME type.
Meanwhile, most of the articles in Wikipedia open correctly. Only a few seemingly random files do not open properly.
Some people experiencing this problem have found that the solution to this problem is simply to register with Wikipedia. After creating an account and logging into the site, the problem seems to disappear entirely. This is an easy way to deal with the problem and suggests that the root cause might somehow involve cookies. [speculation] Others have reported that uninstalling the Google Desktop seems to have fixed this problem.
Something else that caught my attention, notice how browser notes have the icon for external sites, and talk colon does not:
