Firefox Community Forum

Firefox 157.0 is displaying some websites incorrectly. Newsmax pages turn white and McMaster-Carr is also displaying incorrectly such that I cannot make an order even if logged it. The same sites work correctly in Edge which I have an intense dislike for. I have already restarted Firefox and rebooted Windows. This started after the Firefox 157 update.

And it is rather annoying that the report does not tell me which addon is misbehaving either. I do know it runs just fine without any addons enabled so hence, the problem lies with a buggy addon and I'm left in the dark about which one.

I just upgraded Firefox to version 156.0.2.

It no longer plays mp4 content from a website. It says "No video with supported format and mime type found".

This used to be OK.

This just started on October 4, 2026, my home page normally has great news and other articles but now the page seems to be in a constant loading mode. Nothing is displayed.

When i updated my browser today it showed me a page which said that VPN can be used by clicking on the VPN button in toolbar so i tried to do it but it is not showing in my browser and also it is showing nothing related to VPN in settings.

I’m still unable to access Newsmax articles in Firefox. I am getting this error:

“You don't have permission to access this resource on this server.”

Reference #18.d756268.1791195720.16bc0e errors.edgesuite.net

The important detail is that Newsmax works normally in Microsoft Edge on the same computer and the same internet connection, so this does not appear to be an IP or general connectivity problem. The problem appears to be specific to Firefox.

I contacted support yesterday but did not receive a response. Could you please have your technical team look into the Akamai/Firefox access denial associated with the reference number above?

Before the last update, I’m using version 157.0 now, it was possible to simply move a complete Firefox tab using drag-and-drop. I frequently used this feature in a multi-monitor setup. While it is still possible via a right-click and the "Move Tab" option, that takes more effort than simply clicking and dragging.

Is that just switched off and hidden in some options, and really no longer possible?

Thank you,

I was using the "read aloud" function in chat gpt window today and suddenly it started showing me an error message "Unable to read aloud" . It did not affect Chrome. I used many of the troubleshooting recommendations but none worked. troubleshoot mode failed to fix it. private window did not fix it. default change for audio and video did not fix it.

I browse exclusively with Firefox on a Windows desktop. Edge is installed but unused. Even so, Firefox unpredictably starts as many as seven Edge Webview2 processes, which invariably bog the computer down. (Webview2 pops up only when I use Firefox and usually when nothing else of consequence is running; so Firefox seems the likeliest culprit.) Microsoft says that trying to uproot Webview2 will disable many apps and may end civilization. How can I prevent Firefox from invoking Webview2?

Regarding FF v157:

- Mozilla have changed the Graphical user interface of Firefox without asking for consent or providing a clear way to revert back to the old interface, yet again. - They have made changes to the settings, so pre-installed search engines can only be toggled off and NOT removed... - There are a bunch of themes now pre-installed that can't be removed.

I think pushing a change without over way to revert, is why I a lot of people don't donate to the Mozilla foundation

Last upgrade not stable keep loosing history not able to bookmark pages unless I open a new one ? Thank you for any assistance James Monedero mito4@aol.com
