Yes. Libre is the first bloat I remove from every Linux install (followed shortly by Firefox) and OnlyOffice is one of the first installed.

And are you replacing Firefox with Librewolf ?
No. I refuse to use anything based on Mozilla software. I use some form of Chromium variant.
Can I ask why you don’t like them ? (Are you using Brave ?)
Nothing is tested for Firefox. Nothing. I’ve had unending trouble getting advanced things to work (like VTTs for D&D) to the point I just assume it won’t work the moment they say they run Firefox.
I also have some pretty strong personal qualms about the operation and stances taken by Mozilla.
I do not run Brave, though I understand why others do. It offers a nice compromise. I hop about a bit, but atm I use Edge on all platforms. I do my filtering elsewhere in the network stack (pihole, etc) and also have UBlock.
There is a line for every person, between certain of their ideals, and making things work (pragmatism). I respect it’s different for everyone, but I’m very heavily skewed towards pragmatism.
