Currently the Microsoft Edge browser is stuck at TubeShift Extension version 0.0.14.0 which has a minor user interface bug. The bug fix has already been submitted to Microsoft but is pending their review before it is made available to Edge users. It is expected that Microsoft will approve the bugfix by March 15, 2021 and probably a bit sooner.
If the TubeShift icon in the browser is clicked on and there are no results to display than the width of popup will be very narrow and the layout/flow of the user interface elements is very poor; an example image is provided below.
There is no decrease in functionality with this bug.
