Followup-For: Bug #909818
Progress. I had the same problem here(TM). Deleting global and local
fontconfig cache did not solve the problem.
After clearing the local fontconfig cache, that cache would be recreated
and it would get an additional amount of cache entries, e.g. every time
I would start Firefox. In the end, ~/.cache/fontconfig contained around
38000 files. Looking at their content, they pointed to
I used custom fonts stored in ~/.local/share/fonts back then but
currently the directory is empty. After deletion of
~/.local/share/fonts, the number of files in ~/.cache/fontconfig (After
clearing this one a final time) stays small and constant and Firefox is
reacting normal again.
