Hi, Sharif. In the Options menu, click on the Advanced icon near the top, then then General tab. You will find a setting labeled "Check my spelling as I type." You will need to check this box in order to enable spellcheck on websites.

Here is a [step-by-step article with a screenshot] showing you where this setting is located.

its is already enabled

Current Firefox versions hide Check Spelling in the right-click context menu of a text area if the web page disables the spelling check via a spellcheck="false" attribute of this element.

You can right-click in the text editor area and use "Inspect Element" to see if this text area has a spellcheck="false" attribute.
Removing this spellcheck="false" attribute by selecting it via a double-click and using the Delete or Backspace key should make the Check Spelling item in the right-click context menu reappear.
