I can’t seem to open any Word files in Firefox. Doesn’t matter if it’s a new file or an old one, it just won’t open. What’s weird is that it takes me to a OneDrive page saying the file doesn’t exist or isn’t available. But when I switch to Google Chrome, everything works fine.

Since Firefox update to 126.0 yesterday, any video I try to view from the Eurosport website has lost about the top third of the video. Prior to the update, I didn't have this problem with viewing the videos in Firefox, and if I access the website and videos using the MS Edge browser, the videos display correctly. See screen shots below from Firefox and Edge.

On my MacOS 10.15.7 system I upgraded from 125.0.2 to FF 126.0 this afternoon. When I started the new version of FF and acknowledged the "downloaded app OK" dialog all the tabs opened as expected except for WordsWithFriends (on Facebook). WWF draws the full board just fine but then throws a less than descriptive error message: "an error occurred. Please refresh." That is an infinite loop as it will return the same error no matter how many times retry is pressed. I logged out of FB and back in, just in case. No change. FB pages show fine, btw. Closed 126.0 and tried downgrading back to 125.0.2. That version with no longer load (or any of the previous four I had on hand). Consumes 100% of the CPU for about six minutes and then changes to Unresponsive in the Activity Monitor. WWF works fine in Safari and Chrome for what that is worth.

All of a sudden, Firefox (125.0.3), running on Windows 11, is not delivering any sound at all on websites which have music or people speaking. The TOR browser does deliver the sound on those same websites.

Using Firefox on windows 10 pro, 64 bit

Since updating to Firefox 125.0.3 (64 bit) , I am getting all sorts of website problems with font sizes. Some are all extremely small like on google news, others have widely mixed sizes, extremely large and extremely small. Even on this page, support.mozilla.org, I have to zoom 250% to make it readable.

I tried troubleshoot mode and there is no difference. The problems are still there.

I tried the Edge browser and the problem is not there.

I didn't have this problem before the update. I tried adjusting windows and the screen dpi, but I can't find a solution. Just seems to make things worse.

Anyone else having this problem? Any suggestions for a solution ?

Hi Firefox Support Community,

I've been exploring the reviews on SGEats and noticed some performance issues while browsing the site using Firefox. The site has numerous high-quality images and interactive elements which seem to cause slower load times and occasional lag.

Are there any specific Firefox settings or extensions that could help improve the performance for such media-heavy websites? Would enabling or adjusting hardware acceleration settings make a significant difference in this case? Are there known issues with Firefox handling similar content-rich websites, and if so, are there any recommended troubleshooting steps? I appreciate any insights or recommendations to enhance my browsing experience on SG Eats and similar sites.

Thanks!

A few days ago I started having an issue where Youtube videos 1440p and up would frequently skip ahead, stutter or freeze and play audio only. They also stopped loading as quickly as they had before. This issue only happens in Firefox as when I watch Youtube on Chrome everything is fine. I've tried disabling extensions to no effect. Is this a known issue or does anyone have suggestions?

Tenho o Win 11 23H2 com Firefox 124.0.1 instalado. Há meses , devo usar o Avast Browser para acessar o Amazon.com.br ou qualquer site do gov.br. Já desinstalei tudo e reinstalei do zero , sem extensões , mas o problema continua. Alguém sabe me ajudar? Desde já agradeço.

I was able to open reddit.com without any problems earlier, but recentrly I'm not able to load it up anymore. The loading screen is eternal and it doesnt show any kind of error (unless it tries to connect for too long like a couple of minutes, then the error does shows up). The site still sends me notificarions through the browser though. Any other site loads up without a problem. I tried to use methods mentioned in the help article (turned off proxy, turned on network.dns.disableIPv6, deleted cookies and cache). In other browsers (Edge, for example) reddit.com loads just fine. Please help me if you can.

I'm contacting you to ask for help with a problem I'm having with Mozilla Firefox when attempting to visit the website https://proroofingcontractorgreenville.com/. The website won't load, and I'm not sure if that's because of a technical glitch, incompatibility with certain browsers, or anything the browser may be obstructing.

Has anyone else had this problem or has advice on how to fix it? I've tried removing extensions and cleaning the cache on my browser, but the issue still exists.

Any advice or tips on how to navigate the website more easily would be much valued. I'm grateful for your support in advance.
