How to 'Cancel' option changes is firefox?

Hello. Thanks for your help.
During the download (32.0) I chose the FIRST bubble in Options. It sounded good, but I don't like the results.
Firefox changed my HTML, Adobe PDF, files etc. (Prefer that these files are in the original format).

Question (s):
1. I lose something if I UNINSTALL Firefox? Or, all the files back to original?
2. He will give me what I want, if I uninstall then download again but NOT SELECT Option of bubble?
3. should I allow hours (or days) between uninstall it and download it again?
4 using the Chrome for video playback web will be a problem if I keep Firefox as default browser?

Thanks again, IslandFox

Hi IslandFox, Yes, try to reinstall and do NOT make Firefox default browser.

Notes:

(1) prior to uninstalling Firefox, make another browser default browser.

(2) for uninstalling Firefox, do NOT remove your personal data, if you have bookmarks or make the customizations that you want to keep.

(3) the latest installer of Firefox is available on the next page (scroll down to your preferred language): https://www.mozilla.org/firefox/all/
