Since the last update, or perhaps the one before that, both I am my husband have been having trouble with tabs. We are both on Windows 11 but machines from different makers. It is my habit when researching to right click links to open interesting looking things in a new tab and then go back to read all the tabs in turn, the info sticks better that way than reading>searching>reading>searching. I have never had trouble with this before no matter how many tabs I had open, I have a powerful laptop. Suddenly Firefox will act as normal and then after a bit the tabs don't load.I don't mean the rightclick/open in new tab doesn't work but the tab which opens will have nothing on it. Sometimes they will open properly in a new window but sometimes not. Also on the Daily Mail website the page doesn't seem to complete somehow; the relaod icon doesn't appear and you have to click the 'cross' to amke the page stop trying to fetch something (I presume). This doesn't happen with any other newspaper site. I have refreshed Firefox, I have checked all my settings, I am not using a VPN or private windows, I have changed About:config dom.ipc.processPriorityManager.backgroundUsesEcoQoS to '''false''' to get rid of the eco leaf symbol showing in task manager I have Norton as my virus protection. I have closed and reopened the browser and switched the laptop on and off :-) I have read many things on this forum but I have'nt tried this yet as YouTube is not involved https://support.mozilla.org/mk/questions/1384439 So I am out of ideas and it is really annoying me. I have found many other people have this problem, I have been using Firefox for about 20 years and I don't want to have to change but will if I can't get this sorted out! Any help gratefully received, Mary
