Just changed the vetical scrollbar of #firefox on my #pinephone from the right side to the left. Works better for me, because I do not scroll accidantly using the scrollbar when swiping a page up or down.
But still I can`t open urls from #tootle when firefox is already running. A #mobian issue with the .desktop file?
The #firefox on my #mobian #pinephone had been running with --no-remote --private.
In /home/mobian/.local/share/applications I have a .desktop file with those options added.
I do not remember that I put the file there and changing the options to not include --no-remote solved the problem that I had opening an url out of e.g. tootle when firefox is already running.
