Updated Firefox browser for desktop on Mac to 158.0 on 10/15/26

On 10/14/26 using previous Firefox version 157.0 on Amazon.com Prime Video section, pages would load properly and videos could be played properly.

10/15/26 using updated version on Amazon.com Prime Video section, page would initially load properly only to later freeze. Videos could not be played. And freezing could not be corrected unless closing the tab on the browser.

10/15/26 using Safari browser on Amazon.com Prime video section, pages loaded properly and videos played properly.

Clearing cache and site data on updated version of Firefox did not have any effect. Pages continued to freeze and videos unplayable when starting over and navigating to the relevant pages.


Steps to reproduce:

go to amazon.com login to account go to prime video page

expected results video selection appears and user can select and play videos

actual result video selection appear but freezes after a second or two,. videos cannot be played

Repro rate 5/5

Environment Variables Firefox 158.0 Mac OS GoldenGate 27.0.1

Other information Other amazon pages like whole foods and home page and Subscribe & save not affected Just Prime Video page affected

Until a week or two ago, Amazon Prime Video worked without a problem in my Firefox browser. Now I cannot get Prime Video to open any show (the play button keeps spinning and is not clickable). The website is unresponsive as well, although it loads. Here is what I have already done for troubleshooting.

1. Updated Firefox to latest version. 2. Cleared cache and cookies. 3. Checked for hardware acceleration issues. 4. Disabled IPv6. 5. Tested in Private mode with all add-ons disabled. 6. Disabled Enhanced tracking protection.

This is an issue with Firefox since Prime Video works fine on other browsers.

Why Firefox not loading many web pages correctly?

Running a Dell computer w/ Windows 11. More & more web pages do not load properly in Firefox v. 158.0.1. I am updating to v 159.0, now.

Is there anything I can do to retain the functionality of Firefox, when accessing these new web pages?

I've used Firefox since the beta version & prefer it. However, because more web sites no longer load correctly, I will have to change my browser, perhaps to the DuckDuckGo browser. I detest Bing & refuse to use it. Chrome is rapidly following Bing into that category.

HELP!!

Thanks.

I’ve noticed a strange problem in Firefox where some images on a website don’t always load the first time. The page itself loads normally, but occasionally a few product images are just blank. Refreshing the page usually makes them appear. I’ve been noticing this while working on a site I maintain, for example on some of the product pages here https://emcindustrial.com

What’s odd is that I can’t seem to reproduce it consistently. The same pages work normally in Chrome and Edge, and sometimes Firefox loads everything perfectly too. I’ve already tried clearing the cache and checking with extensions disabled, but I’m still seeing it occasionally.

Does anyone have any idea what could cause Firefox to load the page but fail to load individual images? Is there something specific I should check in the Network or Console tools when it happens? 1st image is what's showing on firefox, 2nd is how it should be ( showing on chrome)

Since last update, Twitch has been unable to load videos.

I thought it would be a quick fix since it was a known issue and the temporary fix was to rollback update and stop auto updates. or use a different browser.

Currently use a different browser for twitch but it is inconvenient for me to have 2 different browsers. So, when will this be fixed cause it's easier to switch browser with all my info than to rollback and stop auto updates.

Hello,

For some inexplicable reason, when I visit any Wikipedia page (as of Thursday 8th October 2026), the pages display with a huge oversized font that also impacts the format and layout of the page in my browser. I have not made any adjustments on my PC to increase font display size. Wikipedia is the ONLY website that displays in this manner.

I am running Firefox 115.42.0esr (64-bit), which appears to indicate Firefox is up-to-date on my Windows 8.1 desktop PC. Please note that I am still running Windows 8.1 on this device out of choice.

I reported the fault initially to Wikipedia itself, and the response is that any fault is at my end. I have visited the same Wikipedia pages via Chrome Version 109.0.5414.168 (Official Build) (64-bit) and the pages display normally.

I have attached a sample screenshot to illustrate.

Any ideas how I can resolve this issue please?

Many thanks - Dean
