Just change the yes to no, and your problems will be over. This fix should work on any kind of browser.

    1. I type regedit in run,then it automatically send me to fireshot folder locaation.
    Screenshot Studio for firefox. I Default ; fx_prokey

    2. Double click the fx_prokey,change value from NO to YES. Exit.

    3. Start fireshot,it will say that trial is still expired.

    4. Restart regedit,Repeat #2 Process,
