IIRC it is an extension for youtube that changes titles and thumbnails to more accurately reflect the content of the videos

Ah I thought I saw v3 when I looked it up, so about double the price then but with fees (and probably low demand) my original estimate was probably correct enough

About $15 per CPU on ebay or so, so about $121,000 USD for the CPU’s alone

These days you can merge the SD card with your internal storage which will allow you to install apps on it albeit they will run more slowly off the sd card instead of off the phones flash storage but better than when it could only be used for files

It looks like it has a usb c port on the top and bottom so it might be wired where you can charge with either/or?

This update doesn’t seem to remove any add-ons specifically but turns them off on more sensitive websites if Mozilla has not reviewed them.

It does look like there is an about:config option to turn it off, however it looks like this is most likely to be for bank websites etc. and only for add-ons not reviewed by Mozilla.

Currently, at least, ublock origin and most of the bigger adblock add-ons are reviewed by Mozilla and shouldn’t be affected
