Firefox 14.0.1 has a spell checking error./ bug in the code

Question

I just had all my machines update to 14.0.1 (WIN XP SP3)
I had a clean boot right before the update occurred.
This is the first time I had used this version on this machine.
When the program came up, I had no access to the spell checker at all. Nothing I did could change this (checking and un-checking the feature in the right click menu.
So, I selected the option of restarting the browser in "SAFE MODE" with no add-ons. There was no change at all (still no spell checking)
So, I went to this site, made an account, activated the count (this entire time FIREFOX had no spell checking) and I created a report.
I was most of the way done writing the report when suddenly the spell checking started to work. I made no changes to the settings, when suddenly I had spell checking working.
This means there is an intermittent error;p often the hardest to find from my 20+ years of programming experience (Senior IT contractor)..
So, have find finding this one. Intermittent bugs are the hardest to track, and tend to come from issues like scope issues, settings stored in files/registry, overly convoluted code (like a rush job that isn't fully understood & was just hammered on until it seemed to work). From my experience it often happens in the last steps of finishing a release - accidentally introducing a bug into what was a working section of code (unexpected ramification are a suspect) into a previously working program piece of a program.

Hi BarleySinger and thanks for reporting us this issue.
Yes. Intermitent bugs are really difficult to track and solve, so please try to do this things:
* Try to reset Firefox so all settings that may be creating this problems will be removed.
The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
