FCKEditor Year 2010 Bug for Firefox 3.6 with ColdFusion

January 21, 2010

If you are having problems using FCKeditor on Firefox 3.6, it's due to a, lets call it a Year 2010 bug. You will see a textarea instead of the editor. This probably only exists in the ColdFusion version, I haven't checked the other versions...

The useragent for Firefox 3.6 might look like this:

Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.2) Gecko/20100115 Firefox/3.6

The problem is on line 47 of fckutils.cfm located in the root of the fckeditor install:

stResult = reFind( "gecko/(200[3-9][0-1][0-9][0-3][0-9])", sAgent, 1, true );

Yes that right any gecko browser made after Jan 1, 2010 will fail to match their test.

You can change it to something like this:

stResult = reFind( "gecko/(20[0-9][0-9][0-1][0-9][0-3][0-9])", sAgent, 1, true );

That will give you another 90 years of FCKeditor use on Firefox.

Note this problem will not exist on all versions of FCKeditor, you can also pass checkBrowser=false to the FCKeditor component and it will disable this check. I tried cftextarea on CF9 and it appears to work without modification.

Note: If you don't have a fckutils.cfm file look for a similar line in fckeditor.cfc. Also in some versions of FCKeditor you might get an error stating that the variable width is not defined (due to a bug in showing the textarea).

PS: If you need a ColdFusion Spell Checker for FCKeditor or cftextarea check out Foundeo's Spell Checker Product.

Switch to CKEditor instead. It's a Javascript only add-on. No ColdFusion version.
you just saved my life. thanks a lot for this post
Yeah, we discovered this as well in all our CF8 installs and in the latest FCKEditor as well (2.65). A quick fix was all it took (change 3-9 into 0-9).

Too bad you stop @.hotmail adresses, now you cannot see my really cool Gravatar ;-)
@Brian - Yes that is probably the best course of action. Have you found the migration to be simple?

@Francis - You're Welcome!

@Sebastiaan - I've changed the rule to allow hotmail addresses again, I was getting a ton of spam at one point from hotmail addresses, we'll see how it goes. You need to do more than just change the [3-9] to [0-9], you also need to the change the 0 before it.
We indeed changed this in our fckutils.cfm: stResult = reFind( "gecko/(20[0-9][0-9][0-1][0-9][0-3][0-9])", sAgent, 1, true );
Many thanks, Pete - very useful info!
Thanks Pete!
It doesn't work? :/
Great Post! This worked perfectly.
I'm having issues with cffinder since upgrading to firefox 3.6. it does not show image names or the upload button.

any thoughts.
I actually had to update this in my fckeditor.cfm page not the .cfc Hope that helps
Hey Pete...

Running CF8 locally and I changed that line in both of my instances, and restarted ColdFusion and I'm still getting the plain textarea within FF3.6.

Any ideas?
@Andy - Hmm, not sure double check that you changed the regex properly. Are you using cftextarea to invoke FCKeditor, or are you invoking it directly?
Worked perfectly. You rock Pete :)

Turns out I was editing the FCK instance within my JRun folders when I should have been editing a stand alone instance we manually installed. Got it working now.
rock on!!!

Thanks for the start! I changed mine to use a regular expression of gecko/(20(0[3-9]|[1-9][0-9])[0-1][0-9][0-3][0-9]) .... because the comment above the regular expression in fckeditor.cfc says to check for Gecko ( >= 20030210+ ).

Yours will pass if the Gecko version date is 20010210 - this one won't

Also, note I had to change:
if( arrayLen( stResult.pos ) eq 2 )


if( arrayLen( stResult.pos ) gt 2 )
Awesome, you just saved us a lot of grief.

If anyone's using an older version of FckEditor (e.g. 2.4.3), apply Pete's fix to fckeditor.cfm and fckeditor.cfc.
Thanks i cut and pasted the code just as you said, works like a champ, thanks for posting.

Thanks a million...you won't believe how much grief you saved me (and others)
We are using FCK editor version 2.3.2 in OpenCMS.
I tried all the changes mentioned above, but am still not ablt to resolve the probelm.

I had a similar problem. It turned out that I was editing the right file, but in the wrong location. My system had two instances of FCKEditor and I was editing the one that was NOT being used. Perhaps you're having a similar problem?

@Andy Matthews: where's this file ??
@Mansi: did you resolve the problem ?

We have a custom install of FCK Editor, rather than the one which comes with ColdFusion 8. I was working on the native version.
For OpenCMS users, there is a second file to be changed. Besides /system/workplace/resources/editors/fckeditor/fckutils.cfm you need to make a change in /system/workplace/editors/fckeditor/editor_configuration.xml

Replace in Line 13




VerY Thanks !!

It works in Opencms 6.2.3.
I changed:



wow...thanks a million...just saved my bacon.
Yeah Man, Thx so much... saved me hours
After I apply this fix, I get a FCKeditorAPI is not defined javascript error
