v2.2.3 has problems with "Animate tab" option. Ubuntu 18.04 LTS, Firefox 63.0 x64. When "Animate tab" animates - it causes some memory leaks or read/writes on HDD, so my PC will operate slower and slower and then it will completely frozen, and the only ways to avoid this - to click on monitored tab to stop favicon animationon, or to disable "Animate tab" option at all! Something became unstable with the last FF version.

Please put STOP/START button on top of the dialog box or by click or right click on icon and ALSO to set by default the keyword so that we do not have to select text (regex) everytime we click START.

Love it! works great on laptop...gave it 4 stars because it does not work on Firefox for Android. Can the developer confirm that he knows this and is working on it?
