For those of you who use Firefox, I’m sure you’re familiar with it’s inline spell checking feature. WordPress has it’s spell check option but I never use it because of Firefox’s automatic inline spell checking. It helps me when I write or proofread my drafts. It makes it easier and faster because it immediately underlines a misspelled word with a red line.

However, some Firefox users are having problems with the inline spell checking function not working with the new editor in WordPress 2.1. I found out that this problem is caused by one of the default settings of the version of TinyMCE that is being used by WordPress.

To fix this problem and enable the Firefox spell check in WordPress 2.1, you can download the plugin called FFSpell. It turns the Firefox automatic spell checker back on in TinyMCE. It’s easy to install because it doesn’t need any configuration. Just upload the file into the plugin directory and activate it from the Plugins panel and you’re good to go!

    @ash – Oh I see, the risk is not worth it. Anyways, you can still visit your favorite blogs with IE. You just have to sacrifice on some features that Firefox has and IE doesn't. :D

    @ash – Guru? I don't think so. I still have a looong way to go before I can consider myself that. Thanks for the compliment though. You can only use Internet Explorer at work? That sucks! What if you install portable Firefox on a USB drive and bring it to the office? Would that work? :D

    You're really a guru. Keep it up. btw, as much as I want to, I can't use firefox now. You know. This job really ruins my blogging. :D

    @dimaks – True! Without it, I'm sure I'll have lots of misspelled words on my posts. Hehe :D

    @jhay – Yup, this is another one. I always used the plain text editor coz I never liked using the visual editor. Thanks! :)

    @christian – We share the same sentiments regarding the visual editor. This is for those who use it and I know that there are a lot of WordPress users who do. :)

    @Ymir – Hehe..maybe you really are good in English. Let me know if this helps you fix the problem. :)

    @an2net – Really? You didn't see any inbound links from other blogs? Better wait 'til the contest ends before you release your new layout. Just to be sure. Hehe

    Why'd you give up on WP? I never tried using MT. :D

  • an2net, March 13, 2007 @ 6:51 PM

  • Ymir, March 13, 2007 @ 5:51 PM

    gotta try this.. i have noticed this problem for quite sometime.. i thought it was impossible for me hitting all the right spelling.. lolz

  • christian, March 13, 2007 @ 3:34 PM

    Well, that plugin is not for me because I don't use the visual text editor. I really abhor it.

  • jhay, March 13, 2007 @ 2:26 PM

    This is another issue with the rich-text editor of WP 2.1? Hmm…I never really encounter this issues because I use the plain-text editor since last year.

    But yeah, this one's another brilliant fix-it post. :D
