Firefox Community Forum

I have a custom theme enabled on my browser. Every time I log into Firefox on a shared university computer my theme is turned off for that desktop aswell as my personal laptop. I have to manually enable it on my personal devises again each time after using school computers. Is there a way to prevent this?

As above themes not working on latest version of firefox difficulty reading menu & tabs bar as light blue needs to be dark coloured

Also have difficulty reading your website because of white background will not work on dark mode retinopathy burn
