Very useful add on. it is working well. But needs to be improved:

1) every time user click on a link confirmation is asked to leave the active page. This is annoying and should be optional to be choosed by user.

2) It's working when switching tabs on Firefox. But When switched on apps then return Firefox, Firefox refresh tabs again.

Ps: My device Mi note 9 . Miu 13. Android 12.

Tip: After android 9 when switch on apps all inactive apps are killed by Android automatically. So whenever user switch back to any minimized app , that app is reload again. and user losts all processes. have to start from the beginning.

In the worldwide market there is no remedy for this issue. Your add on can be the remedy for millions of user. if you improve the issues i mentioned your add on will be 1 of the most popular add on. and you can make big money with it.
