Here's hoping it is easy to switch off. Firefox has become extremely crashy, running under Qubes, where the GPU is forbidden, despite my turning off attempts at shader use everywhere I can find. E.g., even turning off "smooth scrolling" made a substantial difference. But it still crashes, even just loading a DDG search results page.
Advice welcome. (No, abandoning Qubes is not an option.)
