Firefox extension shows wrong resources

[Cris70]

I am using Mega extension v4.2.1 in Firefox 124.0.2.
When I open the extension page, all graphical resources are wrong/corrupted:

However, I see no other reports of this kind... what am I doing wrong?
I'm on Linux openSUSE Tumbleweed with KDE6.

Same here, both in Firefox (115.10.0esr) and Waterfox (G6.0.13) on Win 7 x64

Hi guys. Mozilla gave up reviewing our extension at the frequency we do update it, so it has been outdated for quite a while... we're currently at version 5.21.0.

I think your best bet is installing it straight from this repository, as a "temporary add-on", you may find details on how to do that in the README.md file, but also check out #11

PS: We're currently in the process of upgrading our extension to Manifest Version 3, so you may also find some breaking changes, e.g. as noted in #9

Thank you @diegocr.
I tried to follow the iinstructions (and also checked out #11), but as soon as I try to load manifest.json, I get an error message:

I tried to lookup background.service_worker in about:config but didn't find it.
How do I proceed from here?

Apparently, Firefox doesn't yet support MV3's service-workers 🤦🏻‍♂️ (ref)

Try to use the files from https://github.com/meganz/web-extension/archive/9d5b7c1aa359c361f8c8f9722f46ccae849a36d3.zip

Thank you, after using the files from https://github.com/meganz/web-extension/archive/9d5b7c1aa359c361f8c8f9722f46ccae849a36d3.zip and following the hints in #11, I was able to make it work!

Great, pleased to hear that, enjoy! :-)
