There are some objects that may be attached into web
pages which certain web browsers insist on placing in
front of everything else on the web page. Some examples
of this are:
-
Selection lists in Internet Explorer
-
iframes in Opera
-
Flash scripts in most web browsers
Where such an object appears too close to certain other
elements of the web page (eg. navigation) then this can
result in what appears to be perfectly functional code
in some web browsers to be completely unusable in other
browsers. The selection list and Flash situations are
not likely to cause problems when you visit web sites
that use them because these problems occur in Internet
Explorer and the issues will therefore most likely have
been dealt with by the person who wrote the page in
order to make sure that conflicts don't occur. The
one of these that may be a problem for you visiting a
web site is if you use the Opera browser and the person
whose web page it is hasn't considered that browser
in placing their iframes.
The best solution in that instance is to notify the
owner of the page so that they can fix it to work in
Opera. Of course there is still a question of how can
you access the page properly while you are waiting for
them to fix it or what can you do if they refuse to fix
it? Well Opera does provide a facility for you to turn
off iframes completely by going to Preferences in
the Tools menu then selecting the
Advanced tab, selecting Content and
unchecking Enable Inline Frames. This action is
a bit extreme though because it disables iframes on all
of the web sites you visit rather than just the one
where the iframes cause the problem.
An alternative and better solution is to use a user
script installed into your browser to disable iframes
just on those sites where there is a problem (for
example the first site I saw with this type of problem
had a Google Ad in an iframe directly underneath the
dropdown menu at the top of the page so that most of
the menu entries were hidden behind the ad). The other
advantage of using a user script is that you can
selectively disable iframes in other browsers such as
Firefox that don't provide an option for doing so
from the preferences).
The iframekiller.user.js script
just needs to be installed into your particular
browser. For Firefox/Greasemonkey simply right click
the link and select "Install User Script".
With Opera the easiest way is to go into the link and
select "Save As" from the "File"
menu to save the script into your user script folder.
You only need to make one change to the script to get
it to work for the web pages on the site(s where you
are having the problem. Simply find the line near the
top of the script that reads:
// @include http://example.com/
All that you need to do to get the script to work on a
specific site is to substitute that domain name where I
have example.com in the script. To get it to work on
more than one site simply repeat the @include line as
many times as needed and specify the domain name of
each site where you want to disable iframes on a
separate @include statement.
Disclaimers: This user script removes all of the
iframes from pages on the specified sites. In some
instances the iframes are needed in order for the site
to function correctly. Neither the author of this
script nor About Inc accept any responsibility for any
site whose functioning you break through the use of
this script. If this script breaks the functioning of a
site then you will need to find a different way to
achieve your desired result.
Many sites display advertising in iframes. Please do
not use this script to remove advertising from sites
unless the placement of that advertising makes the site
unusable in your browser. A lot of information on web
sites is freely available because the owners make
enough from the advertising to fund the operation of
their site.
Final Note: If iframes are causing a usability
problem on a site then please don't forget to let
the webmaster of the site know. Most should be happy to
fix problems with the usability of their site making
the use of this script unnecessary.
