Hello. I've got a problem with the latest PrevX and Firefox. Sometimes the page in Firefox hangs, and I usually notice it when I'm typing, because no letters appears even though I still type, and after two seconds, it stops hanging and my letters are appearing. Also if you hold down the shift-button to add a capital letter, and it hangs at the same moment you push it down, all the letters written during the hanging, become capitalized, even if you've released the shift-button a long time ago. I've experienced this on both of my computers, and Firefox doesn't hang when PrevX is uninstalled. Any solution? Thanks.
