I don’t know why some moron downvoted you, but the answer is maybe. For reference, I have always bypassed SSH firewall blocking by sneaking SSH packets within https.
The only way this won’t be possible is if the government enforces installing a certificate to use the internet, so that they can do a man-in-the-middle-attack. I heard this is already being done in Afghanistan.
All files open OK for me on libre office so far.
Also there’s office online, btw, for emergencies.
