📝 Important Notes

You can always save your preferences in FUIX. Internet connection isn't required to change the preference. Only required if you want to see the styles in your feeds.
After making changes on FUIX it may take 1-3 seconds to load the styles on your Facebook, Messenger, and Instagram feed. The styles loading delay also depends on your internet speed.
If your Facebook, Messenger, or Instagram feed is opened in your browser and the internet connection isn't active. At that time if you turned off any option that style will be gone if activate that again the styles won't load until the internet connection is active or reload the page.
You don't need to worry if you don't see any changes. There will appear a popup alert what happened.
The webpages style depends on the organized DOM by Facebook / Messenger / Instagram. The DOM can be updated anytime without any notice and you may see design conflicts on that moment or after that. In that case, you can turn off the options for 48-72 hours and we will update the design withon this time. If you don't see any changes in this time, then create an issue in this repo (follow the next step) or conact me.
If something happens wrong with the FUIX addon or you notice any issue just click on the "Report Issue" button from the FUIX addon footer.
