Diễn đàn hỗ trợ Firefox

I am no longer able to log in to eBay using Firefox. I am using Firefox 78.15esu bc I have an older Mac that will only support up to Mac OSX 10.11. I was able to use eBay up until this morning when the site asked me to log in again... and verify that I am indeed a human through the hCaptcha checker. The checker cycles between identifying horses and lions... and every time, I seem to pass but then comes the message "Failed to pass Captcha, Please try again." I can access eBay using Safari and Chrome. Right before the failure today, the rendering of the eBay pages was odd... needed 3x the screen width to see the whole page. eBay says that the problem is on the Mozilla side of this issue... mostly because I can use a different browser without problem. I think I am in agreement with them. I don't really want to use a different browser but I will bc I like eBay, too. Please advise.

my mac desk top is version 10.11.6 its from year manufactured 2008 no more updates available, dont understand how to keep my old desk top from 20087 usable with firefox after March 31st 2024

I accidentally deleted the blue star on one of my book-marked items and am struggling to get it back. Its very useful so i can see immediately if somethings already been bookmarked. Plus I could remove easily and/or put into other folders. All solutions appear to be to go to customize firefox and to drag and drop in some bar at the top of the page BUT when i do this it STILL doesn't come back. HELP!!! (Please explain in total laymens terms and don't nauseate me with technolingo.)

Now you've updated firefox, my tank of a Mac can't function with netflix. So thanks a lot you bunch of techy twats, with your great ideas to make everything better.

When we've got to the end,

we'll realise we cant get back to the beginning.....

I accidentally right clicked and hit "Remove from Address Bar" on the Reader View icon and now it's gone. I tried typing "about:config" into the browser and searching "reader" then selecting the "reader.parse-on-load.force-enabled" toggle to "true" and that didn't get it back. Is there a way I can get it back?
