Hi, thanks for the add-on, but I may have found a bug. To reproduce:

1. Navigate to "https:// razlozhi.ru/durak-perevod"
2. Click on the "Все комментарии" button.

Notice that Firefox starts to consume a wild amount of CPU time, which doesn't happen with the add-on disabled.

Doesn't work on "lazy loading" pages, need to reload the page with F5 to enable auto show of controls.
Example: joyreactor.cc/tag/webm

Update: nothing changed in v.4.0.0 on Firefox 145. You need to scroll to the bottom of the page and click "Next" to see the problem.
