bug: Extension severely slows down the browser when a lot of elements get added to the DOM

[griffi-gh]

Browser info

Firefox 123.0.1 (Windows)

Browser extension version

1.6.3

Website

Any website which adds a lot of elements to the DOM, such as github repos with tons of files.

Bug description

• Open any website which dynamically adds a lot of elements
• Observe as the extension causes the whole tab to freeze

Stopping the extension (using the "Stop" button) causes all slowdown issues to go away (until the page is reloaded), actions that used to take a couple of seconds/freeze the tab now finish instantly

Comparison of page performance:
With extension enabled:

The difference is night and day.
