The Technophiles Photo Effect by DJI

Interesting filter. Both the version with multicolor and with a single color background looks very nice.

Check back your filter in your FF. Is it seamless?
Sometimes the reason can be that we saved the filter before clicking seamless.
Otherwise..... try resetting all basic settings.

Today something weird happened to me with Outlook ( hotmail ).
Without changing absolutely nothing in my browser and adding nothing new in my PC, I logged in my mail and tried to write an email.
I could type the title of the message. I could type the email address of the receiver. But I couldn't type any message. I checked from my phone and I could do it normally. I tried various things ( log off, close the browser, switch off the PC, etc. ) then simply deleting the browser history solved everything.
