I have been using Vivaldi browser for windows and really like its speed and features. On the bottom right corner of the page u can adjust font size with a slider, its set at 140%. Every time I adjust it works but there is a problem; if I open a new tab or got to a different site it resets back to 140%. I changed the settings but it still does this, anyone know how this can be fixed:help:. Other than that I do highly recommend giving Vivaldi a try.
