I'm using version 143.0.1 (aarch64) on macos 15.6.1 (24G90). Ever since I updated to 143, many web sites no longer work.

For example, I get a completely blank page at https://banking.dkb.de/ - see source below.

At https://outlook.office.com/mail/inbox I get an error page - see below.

Here is another example of a blank page: https://www.aircanada.com/home/de/de/aco/flights.

Moreover, the inspector is completely blank for _all_ pages.

The abve pages work fine in Safari. I have used FF for ever since the first release, but am considering ditching it now. I can't find anything about this problem googling.

Please help!!!

The links on the site tasteofhome.com stopped working recently. When you click on them nothing happens. If you load the same page in chrome they work fine. Any suggestions? Or is this a bug Sample URL https://www.tasteofhome.com/recipes/chicken-and-bows/ but there are many more

I have a number of old ReayNas Duo machines which I cannot afford to replace. Until recently they worked fine with Firefox after setting TLS to 1. Now, although I can log in, the menus done' work. Instead of taking you to the menu item the they close the menu & add 'Duo' to the page title. This is repeated each time you try to use a menu. The only exception is the 'logs' option, which seems to operate correctly. I'm using Firefox 143,0,1 on Linux Mint 22.2.

Just upgraded one computer to Firefox v143.0.1 and now familysearch.org is very slow and will not load hints. v142.0.1 is still on my other computer and familysearch.org works normally. Within familysearch, I can click on a hint and a pane opens on the right. It normally populates within a second or two at most. With v143.0.1, it takes a minute to partially populate, then it goes no further. With v142.0.1 it works normally. I've disabled add-ons. Cleared cache. Deleted TEMP files. Restarted browser. Restarted computer. Nothing has worked. Previous upgrades over the years have not had this issue. Other browsers (Chrome, Vivaldi, Brave, Edge, SeaMonkey) do not have this issue. Attaching a picture of this page: https://www.familysearch.org/en/tree/person/details/G4QP-T3S A free familysearch account is required to see it--only an e-mail address is required. The right pane has been trying to load for over 4 hours at this point. Normally takes about 2 seconds.

When I search Google Images in Firefox, this pops up. I tried using an extension to hide it, but I can't see the rest of the image, which is inconvenient. Microsoft Edge and Google Chrome load it, so it's not an issue. Is this a Firefox feature? It's a hassle to disable the extension just to read the rest. Could you please give me some advice?

Cannot open AOL Mail or Facebook at times after sleeping my PC. If I revert to my Laptop or using MS Edge on my PC all is fine. I have reinstalled Firefox, but problem persists from time to time.

I try to download a page, which has always worked. Now today its only partly being downloaded. All information on the page is not downloading. I have used the same link and downloaded on Chrome and it works just fine. I cant understand what i need to do to make it work as always?

Please help me out here, Axel

Hi

Up to a few days ago I was able to see "View all memories" from One Drive in Firefox. Not anymore.

I am subscribed to One Drive. Every few days I get an email from One Drive with the past memories from the day of the email. I will open the emails and click on "View all memories" then it would take me to the One Drive and I would be able to see those pictures individually. For a few days now I have not been able to do this on Firefox anymore. The website goes to gray like it is trying to download the pictures but it gets stuck there.

This is happening both on my desktop with Windows 7 and my laptop with Window 11. Everything works in the Microsoft Edge browser. I can see all the images individually from that day.

I have communicated this problem to Microsoft One Drive and it seems to be a browser problem. Is there any way that this problem can be solved in the Firefox browser?

I would appreciate your help, Amy

the Shaw webmail opens correctly, and it lists all the email messages. But when I click on an email it opens only the header of the email but there is no content of the email showing. I've checked with Shaw and the problem is with Firefox. I tried signing in to Shaw webmail using a different browser and it worked fine.

I'm using the latest stable version of Firefox (143.0.1 (aarch64)) on MacOS Tahoe and have been experiencing issues with these pop up elements not rendering correctly. Things like Facebook's Notifications dropdown or editing spreadsheets in Google Sheets, etc.

The element will only partially render, with some of the content clipped or hidden, almost like a z-index handling issue. Refreshing the page does. not fix the issue. The only way to see the content is to re-size the full browser window, forcing the browser to re-paint the page.

Same issue does not happen using Safari or Chrome that I've noticed.

I've tried reducing protections, disabling all extensions, clearing history & cache, etc.. I also fully re-installed Firefox (going from the Beta channel back to stable releases).

Anyone else experiencing this?

On Firefox, the line graphs slowly stretch downward at

     https://www.oneblood.org/donor-portal/health-summary/iron-count.html 

as if the image height is being incremented. (Chrome & Edge display stably.)

I am having difficulty using Google Sheets within Firefox Developer Edition 144.0b4 (64-bit) on Linux Mint 22.2 Cinnamon. When I load any of my Google Sheets, I am unable to scroll. This includes when using a blank sheet.

I also have Firefox 143.0.1, which seems to still be functioning correctly.

I get this from Microsoft 365 excel when opening an .xlsx file: "Unsupported Browser Office uses new browser technology and works best in the latest browsers. Please upgrade your browser"

Why?
