The addon works, and seems simple and easy to use.
However, the required permissions are WAY to broad, and it's just adware to say the least.
Its source code is packed/obfuscated.
Avoid at all costs.

Illegal tracking links were detected by the company's IT security check firewall. After disabling this extension, the firewall did not report it again.

Оновлює, але без звуку, хоча всі можливі звукові функції включив. Не розумію, в чому причина. Без звуку немає сенсу, треба тупо дивитись на екран... Кілька разів оновлює і зупиняється саме, навіть якщо нічого не чіпати. Фігня якась.

It is using 100% cpu in the extensions section.

Very bad, please report

Sometimes it just started when I type messages on web.whatsapp.com (1-3 times per day), do something please, year ago same thing was happening. I mean when Addon is stopped! It just start refresh the page every 5 sec.

I don't like its gathering browsing data and sending it somewhere.

I don't want my browser data collected and you have to agree to that to use what should be a 3 line code extension.

Automatically resumes when Firefox starts, great for docker container.

Avoid! Russian spyware

Please add the function of updating the page while the tab is active (open)

Addon records private information and sells it to other companies.

Really nice and easy way to refresh a tab. Does not take much resources either. Thank you!!!

Excellent for notifying changes on multiple sites. Works on containers. It seems that the check boxes are not saved after it detects a change [when "Show notification (any changes)" is checked] in a tab and stops the timer. I had to use a macro just to automatically check them if they're unchecked. There should be a save options feature.

太棒了，以后再也不用鼠标连点器了，设置一个不会超时的时间就可以一直保持在线状态了！
