I installed the XFCE edition of the LMDE last night on my old Dell Inspiron lappie. Did a dist-upgrade with (seemingly) no problems.
There's something odd going on in Firefox though. Every instance of the letter "m" is messed up (see attached screenshot):
(It upgraded to 9.0.1 during the dist-upgrade--not sure if this was happening in v5...)
Any idea what could be going on there--or how to fix it?
