Turn it off automaticly on some websites.

**What problem does this solve?**
It lags the text editor page for Wikipedia so much that I gotta turn it off. It would be nice if the extension could turn of for some pages automatically and stay on most of the time.

**Proposed Solution**
How should it work?

**Examples**
Show, don't tell.

**Component**
- [ ] Core engine
- [ ] Plugin/Extension
- [ ] Other: _____

**Additional Context**
Any other relevant info.

No file, test, or entry point is named; begin by locating the plugin/extension component responsible for enabling the checker on web pages. Clarify how users select websites and verify that the extension turns off on those pages while remaining enabled elsewhere, including the Wikipedia editor case.
