Firefox সহায়তা ফোরাম

Hi, thanks a lot in advance and sorry to bother. :)

I have a couple of desktop/laptop devices synced with the same account. When I make a backup/export of my bookmarks in each device (.json/.html files) the checksums of those files don't coincide between devices. Nevertheless, if I open the exported HTMLs in Firefox and save them as Text Files, the resultant files have all the same checksum (sha256sum), i.e., are all the same.

Is this how it is supposed to be? Or should my bookmarks JSON/HTML files be exactly the same in all devices and something is wrong?

Thanks a lot in advance.

All my bookmarks have disappeared from bookmarks. I restored bookmarks in the menu folder but my bookmarks in the bookmarks toolbar are still missing. How can I get my bookmarks in my bookmarks toolbar back?

I added an Add-On to try it called [by Firefox by Mozilla Firefox] Notes by Firefox by Mozilla Firefox which I have since removed as the Add-On has corrupted my Bookmarks. When I click 'Show Sidebars' my Bookmarks don't show (thought they are there) but it's as though the font is white making it impossible to see them.

If I click Bookmarks I can see them and/or when I click on Manage Bookmarks that option opens and I can see all my Bookmarks. This only happened after I added "Notes by Firefox by Mozilla Firefox" Add-On. I was thinking there could be possibility it could have been caused by changing the appearance to Dark Mode, (for example Facebook or Twitter, etc).

There must be a better fix then to refresh / restore Firefox to its default settings as I have about 90 Tabs Open
