"Did you copy and paste some script into your developer tools console without knowing what it does?"
No, I never do this because I know the risk of getting your information stolen.
"Do you have any browser addons installed that might change Imgflip?"
No, the only extension I have is Grammarly and I don't know how or if it would change it.
That is what asdfperson135 thought, (You can ask him the "first" thing happens to him) it usually happens when I have the browser window set to fit half my screen,(The other half being youtube videos, etc.) asdfperson135 told me how to use inspect but it still made no sense, I understand fully this is a possibility but I swear that the inspect tool is not what I am using, I have no possible explanation as to what could be happening though, maybe a probably a weirdly set up feature in the notifications system?
