Has support for X11 been removed?

Recently I have been unable to go to websites where I have had accounts for years. I can no longer access sites like Chewy, Etsy, and even Pinterst. On the latest failure to sign in to Etsy the message I got is "Please enable JS and disable any ad blocker" I don't want to learn another browser. Please understand I'm a senior so not as savy as you young folks. My Firefox browser is 140.0 so it is up to date

Upon upgrading to v140.0 on macOS Sonoma 14.3 (23D56), YouTube no longer renders.

All add-ons (ad-blockers, development tools, accessibility tools, etc.) were removed and still the same non-rendering as of this evening June 24, 2025.

Why did Wikipedia suddenly appear in the address bar at the top and when I try to put in address it goes to Wiki on them not the website. The search bar in the middle that was Google is now Wikipedia. How do I get rid of it and go back to how it was before?

I use Windows, and my browser is already set to open windows and tabs and to automatically open Firefox on startup. My history is set to Remember History. I've tried using Ctrl + Shift + T with no luck. What else can I do to get this function back?

I can't log in to many sites in Firefox and have to use Chrome which I hate The IRS site is

Error from: https://sa.www4.irs.gov/sso/?resumePath=%2Fas%2FrjpK07Gjyi%2Fresume%2Fas%2Fauthorization.ping&allowInteraction=true&reauth=false&connectionId=SADIPACLIENT&vnd_pi_requested_resource=https%3A%2F%2Fla.www4.irs.gov%2Fesrv%2Ftds%2F&vnd_pi_application_name=TDS Reference ID:

What is the problem?

When I click on NY Times link, I get this message: You have been blocked from The New York Times because we suspect that you're a robot. I'm just an old guy with a low tolerance level for tech glitches. Any help greatly appreciated!

I called NYT Support, which tells me it must be a Firefox issue since I can open in Chrome, Safari. I thought it might because I have the Enhanced Tracking Protection box checked, but unchecking does nothing.

Out of ideas.

Hello all:

Just downloaded version 140 and ran into an immediate "visual/appearance" problem with regard to the background color(s) of the sidebar bookmarks view. Many themes now have totally dark sidebar colors and not readable (see screenshot image upload with this posting). I always have my bookmarks (almost 1200 of them) displayed in my sidebar, and this is the first time an issue like this has arisen with a Firefox update.

To remedy this scenario, I must use very light colored themes that have a white background when you bring up the sidebar bookmarks. If not, everything is totally dark and unreadable.

Any ideas or help on this one?
