I followed the upgrade steps in the readme, but my Mint instance is having some major issues rendering its various panes:
All panes are collapsed by default, and when I pick a tab, it’s displayed, but next time I revisit Mint, everything is collapsed again.
As soon as I to hit one of the pane’s tabs (e.g. under Visits), the pane uses up the entire width of the screen. Resizing it will eventually change the pane width, so it doesn’t use the entire width again, adding others as there’s enough room.
Clicking individual tabs within a pane doesn’t seem to highlight (in white) anything other than the first, although I seem to be successfully switching tabs, based on the content changing.
Despite there being plenty of room in the top toolbar, peppers are listed in a drop down menu.
These problems exist both under Windows and Mac OS in Firefox 184.108.40.206. I have about 10 peppers installers, but temporarily disabling them via the preferences didn’t seem to affect things.
