Editing Encyclopedia:Browser notes (section)

===Unwanted effects===
Some [[browser extension]]s are not fully compatible with Wikipedia or may have unwanted effects. Some extensions add text like when editing <code><nowiki><div class="myEventWatcherDiv"></nowiki></code>, <code>QuickiWiki Look Up</code>  or <code><nowiki><a class="ktg6us78hf8vdu7" href="javascript:void(0)"></nowiki></code>. Most of these are detected by [[Special:AbuseFilter/345|Edit Filter 345]] which issues a warning message.

====Consent-O-Matic====
* May break wikilinks during editing, e.g. changing <code><nowiki>[[foo]]</nowiki></code> to <code><nowiki>[foo-en]</nowiki></code> or <code><nowiki>[[foo|bar]]</nowiki></code> to <code><nowiki>[foo|bar-en]</nowiki></code> ([https://en.wikipedia.org/wiki/Special:Permalink/1111132766#Wikilink_markup_being_changed_by_MediaWiki discussion]).

====Dictionary of Numbers====
* May arbitrarily remove strings starting with numbers when editing ([http://en.wikipedia.org/w/index.php?title=User_talk:Gareth_Jones&oldid=556165153#Random_removal_of_strings discussion])

====[[NoScript]]====
* Intentionally blocks scripts (user-configurable by website) but may prevent fallback to the normal behaviour for browsers without JavaScript enabled, e.g. breaking the "New section" feature for some users ([[Wikipedia:Village pump (technical)/Archive 198#New section tab not working when JavaScript is disabled|discussion]])

====WikiTweak====
* Has a "Quicki<!-- Break string caught by edit filter -->Wiki" option which may arbitrarily add the string "Quicki<!-- Break string caught by edit filter -->Wiki Look Up" when editing ([http://en.wikipedia.org/w/index.php?title=Wikipedia:Edit_filter/Requested&oldid=555558125#Adding_QuickiWiki discussion])

====[[StumbleUpon]]====
*May display italics markup <nowiki><i>...</i></nowiki> in page names instead of rendering in ''italics'' ([[Wikipedia:Village pump (technical)/Archive 95#Odd rendering of articles in 64-bit Firefox|discussion]])

====[[Skype]]====
[[File:QuestionaboutSkypeicon.png|thumb|right|If you find the Skype icon in an unexpected place, like in this image, your browser is likely misinterpreting a set of numbers as a phone number.]]

*May interpret certain integers as phone numbers and [[Features of Skype#Application features|turn them into links or icons]] (See image).

====Web filtering====
*Some [[content-control software]] ([[List of content-control software|list]]) may automatically block content it deems objectionable, or remove certain words from pages

====Displaying ads====
*Some browser extensions including Codec-C and InfoAtoms may add ads to Wikipedia pages without properly informing the user ([[WP:RFAQ#ADS|discussion]])

====File page bypassing====
*Some extensions may bypass the file page and jump directly to the actual file when an image is clicked, for example http://upload.wikimedia.org/wikipedia/en/7/70/Example.png instead of [[:File:Example.png]]
