Hi Olivier below is the the log for the 17th - 18th of March. Just to note: 1. This machine has an old graphics card RV710 Radeon HD 4550 so there could be issues there.
2. I just down loaded Firefox Nightly from their site and ran it. it runs fine with out any graphics issues. So the issue maybe a combo of my old graphics card and Firefox 86.0? Firefox current: 86.0 Firefox Nightly 89.0a1 Firefox 87 is just released so should be updated shortly in Ubuntu we could wait to see if that fixes the issue?
