Changing the Input Language to Japanese freezes Firefox
When I change to Japanese input, Firefox "stops responding" for a few seconds. This is consistent.
I change my inputs from ENG to Chinese to Japanese and back to English, but the freeze only happens when switching to Japanese. I use the shortcut Alt + Shift to cycle through my inputs, but the problem remains when I select Japanese directly. Selecting Mandarin does not manifest this problem.
When I restart Firefox, the problem goes away for a while before it comes back.

Step instructions how you change it?
I usually advise not to use the"Alt/Ctrl + Shift" sequence to rotate the layout, because Firefox uses these sequences as keyboard access keys (Alt+Shift is used for access keys on web pages including about:preferences) and you might accidentally change the layout if you would use them. You can use a keyboard sequence to select a specific layout.

Using the mouse (not Alt + Shift) to directly select the language from the keyboard menu also freezes Firefox.
If the problem return after using Firefox for a while then there might be memory issues or a problem with an extension or with external software.
Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is is causing the problem.
- switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
- do NOT click the "Refresh Firefox" button on the Safe Mode start window

You can try to modify multi-process settings to see if this has effect.
- set number of content processes to 1 if it is currently set to a higher value (4)
