[Bug-gnuzilla] Cannot sync or disable addons (IC Mobile)

[Zeko]

Hello

I'm running IceCatMobile 60.5.1 (the latest version on F-Droid) and I'm trying unsuccessfully to use sync to back up my data in case something happens on my phone.

On about:accounts I'm getting a quick flash of some overlapped text replaced by an eternally rotating blue ring. My guess is that the page has some _javascript_ and isn't running it (while CSS is loaded fine).

Therefore I went to Addons to disable LibreJS but it's grayed out and can't be disabled, like nearly all the other addons. The only addons I can disable and enable are my theme/persona and HTTPS Everywhere.

Is there a fix for this? Ty
