I think the menu isn't sizing properly and I cannot click any buttons to enable the extension.

Works fine for me, I used it in Vivaldi (it´s available in browser without an extension) and i am glad it is available for FF too!

Дополнение для меня очень нужное и удобное. НО! После последнего обновления не работает. Причём, если установить время перезагрузки, которое выбирается из списка, то ещё как-то работает, если установить своё, то - нет. Включение дополнительных пунктов не работает.
This add-on is very useful and convenient for me. BUT! It hasn't worked since the last update. Although setting a reboot time from a list works somewhat, setting a custom time doesn't. Enabling additional options doesn't work.

The random realoading function does not work, I click the buttons but they do not react to my mouse clicks.
"Adjust Reloading Time

Days Hours Minutes Seconds Variation (%)".
please, fix.

Никчемное расширение, которое не умеет перезагружать то что надо.

"Do not reload when tab is active" option doesn't work. Even when enabled and you're working on the tab it'll reload.

nice

10 seconds minimum

Really pretty and 'could have been' useful little add-on.
My only regret is that when I opt for 'Do not reload when tab is active', it still DOES IT!
And conversely, it did NOT reload a tab at least once when requested.
So unfortunately, I cannot trust this add-on.
