Answer 1

mmm. 1st off, now i can't use my computer AT ALL. it made the whole screen fill with huge print on a TINY Dell laptop, your idea was 180degrees wrong.
frick
i am at the public library now, since i have NO computer, i did until i installed your fix/the firefox techy fix. not.
i have a little screen. and the issue is simple, most programs and sites i view, are too large, so i am always setting to 67% or 80%, it's a hassle. i wanted, obviously doesn't exist, a way to preset it, to always go to 80%, always. that'll work on my screen since i am forever every site, every day, manually setting to 80% or sometimes 67%, just to be able to view and use.
now, your idea, too huge and worse, i used to have another appl. from firefox, which helped some/it showed a EASY drop down, upper right corner, to select right from there, without going in to firefox, a drop down choice i make of a %, was not great but helped.
with the download of your horrible idea, horrible, i lost that drop down and now have no way to undo what your appl. caused, a hugeeee filled screen, unable to view a thing
and, i am LOCKED OUT OF FIREFOX. WHEN I CLICK ON THE 3 BARS UPPER RIGHT HAND CORNER WHICH IS HOW I GET TO FIREFOX TO LOOK AT ADDONS OR FIX SOMETHING OR ASK FOR HELP, I CANT.
SOMEHOW YOUR FILL THE SCREEN APPL. ALSO LOCKED ME OUT OF ANY WAY TO GET IN TO FIREFOX.
SO SCREEN FILLED LOCKED OUT OF FIREFOX, AND NO WAY TO COMPUTE AND AT THE PUBLIC LIBRARY. WHY I TOOK YOUR IDEA AND RAN WITH IT, I DO NOT KNOW.
APPARENTLY, THERE IS NO WAY TO PRE SET FOR EVERY SINGLE SITE EVERY TIME, TO GO TO A % i set, like 80%, AND STILL ALSOOOOOOO KEEP THE PRODUCT I HAD AND LOST, UPPER RIGHT CORNER, WHRE I CAN EASILY AND SIMPLY IF AND WHEN I MUST, DROP DOWN A CHOICE TO GO TO 100% or 80% OR 67% depending on what i need for that site.
how do i undo the horrible appl add on this default 100% GARBAGE? AND HOW DO I UNLOCK FIREFOX YOUR ADD ON CAUSED, AND AGAIN GAIN ACCESS TO FIREFOX TO MAKE SETTINGS AND CHANGE SETTING AND GET HELP?
