Since the latest update of Firefox Portable the pull down menu's like "copy and paste" or the "Main Setup Menu" are not showing any textual information. On the "Main Setup Menu" the Ctrl+ commands show but the text to the left of them does not display. To verify this seems to be a Firefox Portable issue I installed Firefox on my Computer and all it's pull down menu's are working properly.
The menus are all working as expected here on Windows 10 64-bit. Please include additional details like "system details (OS version, 32 vs 64-bit), install path, new vs upgrade, etc." Are you using a theme or setting on portable Firefox that differs from your local one? Have you temporarily tried a fresh install of Firefox Portable to an alternate directory like your Desktop directory to see if the base portable install is working as expected.
Sometimes, the impossible can become possible, if you're awesome!
