If I recall correctly, Internet Explorer's compatibility modes roll back changes made in IE 11 back to how IE worked in IE 6, 7, 8, or 9. Firefox has a few accommodations for older proprietary code written for early versions of IE, but there's no on/off switch for those, they are either on or they don't exist.

But as ideato suggests, this may have nothing to do with ancient website code that only works in older versions of IE. Hopefully we can help you find a way to view it in Firefox.

hello jscher2000, Excuse my Dutch-English"". Thanks a lot for your fast answer. How can I detect that the accommodations, for older proprietary code written for early versions of IE, are active ?

Thanks a lot for your fast answer.

An example of my problem is on http://www.genealogie-stamboom-schrama-gravenmade-bollenstreek.nl/stamboomschrama.htm

The lines of text are much too long and outside the screen. Only to see by scrolling.

I found IE-tab as an solution for my problem. Have not yet tried it. IE-tab for Google Chrome has a price of 19 dollar and it works.

IE Tab (version 2, Plus, etc.) is a family of extensions and plugins that embeds Internet Explorer into a Firefox tab. It's easier to just load the page in IE (and free). For example, you can send a page or link to IE using this extension:

Firefox honors the "stretchy" nature of tables unless you* set them to a "fixed" layout. This allows the table to consume more than the allotted space. You can modify the page to resolve that issue using a little script, but I don't know of a tool that can investigate these problems automatically as you browse. That would be cool.

* You = web page author

Anyway, if you're interested, the script is:

var new_style = document.createElement('style'); 
var rule = 'body > table {table-layout:fixed !important;}';
new_style.appendChild(document.createTextNode(rule)); 
document.body.appendChild(new_style);

You can run a script against a page using Firefox's Web Console. If you want to see what it does, while view the top part of the page where the problem is most evident, open the web console as follows, either:

• Ctrl+Shift+k
• "3-bar" menu button > Developer > Web Console

Paste the entire script in the space at the bottom and press Enter to execute it. The information in the main area should snap to the browser windows margins immediately. There is a link bar at the bottom which uses non-breaking spaces and non-breaking text elements, causing those links to stick together like glue. Not sure why they thought that was a good design.
