Fórum podpory Firefox

I have recently bought a new laptop and installed Firefox, which I have been using for a long time. After signing into my Firefox account, everything synced over to my new Firefox account, apart from the colorways theme that I chose with the Firefox 94 update - mine is "Foto - Soft". Is there any way that I can get this theme on my newly installed version of Firefox? Thanks.

Trying to open any link from a pdf opens a page with the url resource://pdf.js/web/ instead of opening the link. The attached image shows what the page that opens looks like. This does not happen on Edge, so it is a Firefox issue.

I have updated to the newest Firefox version and the issue remained the same. I tried clicking on "viewer.html" and it brought me to an empty pdf page that just loads forever and cannot be downloaded.

Please help. I do not want to use Edge or go back to Chrome, but I will if this can't be resolved.

I changed the screen shortcut icon for https://mappingsupport.com.

Then in the profiles folder, I renamed the file favicon.sqlite, closed Firefox and restarted my PC. But when I saved the mappingsupport shortcut to my screen, I still see the old shortcut image.

I also tried going to Privacy and Security where I deleted 'Cached web content'.

How do I tell Firefox to get rid of that old shortcut image and use the new shortcut image instead?

Chrome on my PC saved the new shortcut icon to my screen. My iPad also saved the new shortcut icon to the screen.
