To find the correct solution to your problem, we need some more non-personal information from you. Please do the following:

  1. Use ONE of these methods to open the Firefox Troubleshooting Information page:
    • Click the menu button New Fx Menu, click on help Help-29 and select Troubleshooting Information.
    • Type about:support into the Firefox address bar and press the enter key.
  2. At the top of the Troubleshooting Information page that comes up, you should see a button that says "Copy text to clipboard". Click it.
  3. Now, go back to your forum post, right-click in the reply box and select Paste from the context menu (or else click inside the reply box and press the Ctrl+V keys) to paste all the information you copied into the forum post.

Can you also please share what you are using for TTS? Is it RHEL native?

If you need further information about the Troubleshooting information page, please read the article Use the Troubleshooting Information page to help fix Firefox issues.

Thanks in advance for your help!

Hi, I am without my notes tonight, so please forgive me on the directions. Need for you to get to your Options page (windows) so where you will find all the Firefox Controls and in the Search Box please Copy/Paste accessibility in to the box. Please take the Check Mark out of Prevent accessibility services from accessing your computer. (I hope) I think this shows it is already allowed : accessibility.browsewithcaret: true But just checking.

You will find some info a page bottom of this URL on programs and add-ons
