Why do words and letters not show up or change order when I type on Facebook at times?
This is an on again off again problem. I just tried to comment on a Facebook post. Some words did not show up. Letters were missing. Half the sentence looked jumbled. I gave up cause I could not get a readable sentence.

Do the letters take a while to display on the screen after you hit the keys? Please ensure that your keyboard is in 100% working condition and that there are no faulty keys.
I do see on the troubleshooting data that has been provided to me, that you have a lot of addons installed. Some addons have been known to cause issues with various websites.
Try Firefox Safe Mode to see if the problem goes away. Firefox Safe Mode is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes).
If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:
- Click the menu button
, click Help 
and select Restart with Add-ons Disabled.
If Firefox is not running, you can start Firefox in Safe Mode as follows:
- On Windows: Hold the Shift key when you open the Firefox desktop or Start menu shortcut.
- On Mac: Hold the option key while starting Firefox.
- On Linux: Quit Firefox, go to your Terminal and run firefox -safe-mode
(you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
When the Firefox Safe Mode window appears, select "Start in Safe Mode".
If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, theme, or hardware acceleration. Please follow the steps in the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article to find the cause.
To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.
