Looks like it's time to get something newer. If you have access to a newer computer you can test. I'm able to replicate the issues on Win7. see screenshot

I am not changing my system because of Firefox's inability to handle Windows 7 ( a far better operating system than Windows 10, and from what I hear Windows 11) Google Chrome does not have this problem. So, with a heavy heart, I say goodbye to Firefox. Thanks for your response.

Chrome (also Chromium browsers) dropped the old EOL Windows 7, 8, 8.1 as of Chrome 109 over three years ago as it was released back on Jan 10, 2023 so it is old and vulnerable now.

Firefox is the only major web browser still supporting the EOL Windows, 7, 8, 8.1 as they just very recently decided to extend updates til later August 2026 as Fx 115.33.0esr released on Feb 24 was originally the last planned update.

Many websites are updating so it needs newer versions of web browsers like newer versions of Firefox. Just because a couple sites seems to still work in a three yer old version of Chrome and not in a more current version of Firefox does not automatically mean it is a problem with Firefox. Besides if websites were made properly to standards then it would work in Firefox 115 and later and then perhaps not work well in the old Chrome versions like 109.

I downloaded and installed Redfox. It works. I can barely tell the difference between the two. One nice thing is that I didn't have to change parameters in about:support and about: config to get single spacing on my bookmarks drop-down list. Thanks all for your responses. Bye.
