Usually when an extension is interfering with loading and running of browser, this happens.These days on Ubuntu I have found a weird problem with Firefox.
Whenever I open Firefox fresh it takes forever to load the first page.
Also if I open more than 4-5 tabs of youtube in background (with no video running) Firefox hangs causing the entire PC to freeze.
Not finding the same problem with Chrome ... so I will willingly continue to send data to Google by using Chrome
Firefox Quantum works well and is light enough for even an old system.Hmm. So it seems like Tor and Opera are the best choices right now. I thought Firefox is the best option but seems to be resource heavy thesedays.
