toolbarsize to small for high resolution touchscreen

more options

In advance i would like thank you for reading this question.

I'm currently using Firefox on my convertible, which has a resolution up to 3200 x 1800. The problem is, that it is very difficult to use the touchscreen on 3200 x 1800, because the buttons become to small. Is there a possibility to increase the size of the toolbar, while staying on the same resolution? I couldn't find anything about that in the options.

You can set the layout.css.devPixelsPerPx pref on the about:config page to 1.0 or on Windows 8 to 1.25 If necessary adjust layout.css.devPixelsPerPx starting from 1.0 in 0.1 or 0.05 steps (1.1 or 0.9) to make icons show correctly.

Use an extension to adjust the text size in the user interface and the page zoom in the browser window.

You can look at this extension to adjust the font size for the user interface.

You can look at the Default FullZoom Level or NoScript extension if web pages need to be adjusted after changing layout.css.devPixelsPerPx.

Earlier this year, a few other users of 3200x1800 displays reported problems with tiny Flash player control bars. Although Firefox has settings for its own toolbars and menus, the ones rendered by the Flash player unfortunately seem to ignore those settings.

Users have reported two workarounds for this issue, at least on YouTube:

(1) The YouTube Center extension: https://support.mozilla.org/questions/1005923#answer-590458

(2) Switch to HTML5 on YouTube (this will cover many videos, but some will still use Flash): https://support.mozilla.org/questions/982635#answer-520300

I don't recall seeing any workarounds posted for other sites (but it's impossible to read or remember everything posted here).
