Hi,

I've had an issue for a long time where certain websites just won't work properly on Firefox. This issue seems to be specific to this particular configuration of Firefox I have, as the problem doesn't occur on my other MacBook, nor on other browsers, and this problem persists even through upgrading this MacBook from an Intel-based processor to Apple silicon. I've exhausted all of the troubleshooting methods suggested by Mozilla here: https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems. My last hope is that it has something to do with Firefox's browser internals, though I'm not tech-savvy enough to understand what may or may not be working correctly with said internals.

As a few examples of what I mean when I write that certain websites won't "work properly," a reading on Coursera seems to have a scrollbar that can scroll indefinitely without ever actually scrolling the page down for me to read additional text from the article. Certain websites will fail to display certain videos or interactive media. And certain other websites will fail to display anything at all. (I wish I could be more specific in describing these "certain websites," but I can't recall what they are at the moment.)

Let me know if you need any additional information to help diagnose this issue.

I greatly appreciate any time and effort that you may spend trying to help me with this issue!

See the Question details for the Troubleshooting information.

After second to last update Firefox doesn't show bold fonts on my website. In Chrome everything is ok. This issue shows on diffrent computers and diffrent windows version. How to fix it?

It happened for the first time a few months ago, now it has to be repeated several times in a row, now this error appears one after another,after i deleted the history,then again and again

long ago, when I did not allow Firefox to update(i deleted all update exe etc...) then never had any problems with it

Since the last Firefox update (I'm now using Firefox 113.0.1 64bit on Windows 11) when I play a video on Twitter, it plays with the right colors until I fullscreen it. When I fullscreen it, the video becomes darker and the colors are wrong.

• The same happens to youtube videos (both fullscreen or normal size): the colors are not right and they looks darker.
• The same problem happens using both my laptop's internal monitor and the external monitor.
• I tried to reinstall Firefox but it didn't fix it.
• I also tried to take a screenshot of the "wrong colors" videos using the Windows screenshot tool but the output image is displayed with the right colors and not with the darker ones.
• Using Chrome the colors are correct and I never had this problem before the last Firefox update.

Fonts are often way too bold it's unreadable — for example, in the attached screenshot, c is so thick it's looks like o. In other browsers it looks fine. Been having this problem for half a year. Win 10, Firefox 113.0.1

When I see a power point slide on LinkedIn I get this Tab above the slide saying "Scanning for Viruses". It has the options "accessibility mode", "Download Document", "Exit Full Screen", "Skip", "Cancel", "Download", "Proceed anyways". (See picture). Normally it's just a Power Point Slide and I can just click on the right to see more but I can't anymore and I can't make the tab go away.

I looked at this post from Chrome and it works without issue. I disabled all my extensions and it is still happening.

Please let me know what i need to do for this to stop. My only guess is that I updated my Firefox recently, so maybe some new update caused this?

Thank you!!

I don't know if breakage is the correct topic. I keep Ring.com open to the dashboard in a pinned tab. A few days ago, I had viewed and cleared videos as usual and later returned to view new activity. The site requires logging in every 30 days and so seeing that I needed to do so was not a surprise. What was a surprise was that the login buttons were grayed out. I closed the tab, cleared the Ring cookies and cache and tried again. No luck. I wondered if there was some other setting that I didn't know about and decided to open a private window and try it there. To my surprise, it works. I'm stumped. I'll attach the raw data from the private window as a .txt file. Darn. I can only attach an image. Well, I have it available and can copy and paste it into a subsequent post if you think it would help

I used to go to this website which i have account and now it will not let me login it says it is unsecured how can i get it back to secured so i can login i get this message An error occurred during a connection to yecustom.com. PR_CONNECT_RESET_ERROR

Error code: PR_CONNECT_RESET_ERROR

Hello All After a Best Buy install of a new SS drive I am having trouble recovering firefox. FF loads ok but it is just a blank page. When I try to go anywhere it complains of an SSL error. I have been happily using FF for a long while so I have had no interaction with Microsoft for some time but it seems they are trying to force me to use chrome or edge and the oh so wonderful Bing. I am still looking for an answer but having to use chrome which I am unfamiliar with. any help appreciated Thanks

Hi Folks, I'm unable to connect to a device and my support folks are telling me that I must install Mozilla Firefox Version 24 in order to connect to the device.

I have no idea what my current version is but can you tell me how I can install Mozilla Firefox Version 24 for a short time so I can connect with my device?

Thanks, Frank [removed email and phone# from public forum]

You keep saying you fixed this problem and obviously you didn't. Firefox will not let me sign into starbucks.com. Keeps saying sign-in unsuccessful. Site works perfectly with safari.

After update to 113.0.2 I face a problem with the login-page of a bank. Windows 10 Pro 21H2 19044.2965 (64bit) The page I get you can see by enclosed screenshot. With the version 110.0.1 there is no problem to get access. The website owner assumed a pop-up blocker or VPN (not used) as a reason. Can you help? Kind regards, Michael

These bugs have probably already been reported but just in case they haven't there's an issue where dates can't be viewed on Facebook posts without hovering the mouse cursor over the title of the post. The other bug is the cursor often, but not always disappears when commenting on posts.

Hey there, I have a website for my business. The website is performing well and smoothly opens on all web browsers. But some of webpages have loading issues on the Firefox. What could be the possible reason for this? I need help how the issue can be resolved? This is the URL of my website https://www.newdayconstruction.co/ . My other Electronics business site loads very smoothly on the Firefox.

Hey everyone, I'm having trouble opening the website https://learnaboutcat.com/. Every time I try to load a full page, an article, or a category, it simply doesn't work. I'm not sure what caused this issue, but I'm eager to find a solution as soon as possible. Any assistance you can offer would be greatly appreciated. It would be really helpful if you could try opening a website, click on any category or article, and let me know if you encounter the same problem. Any suggestions or solutions you can provide will be highly valuable. Thanks a bunch!

The following issue may occur if you embed the Amazon Connect Contact Control Panel (CCP) into your agent application and your users access the Amazon Connect CCP using the Firefox web browser with Enhanced Tracking Protection browser setting set to Strict.

An upgrade to Firefox, specifically Firefox non-ESR version 86 released on February 23, 2021, introduced Total Cookie Protection

which modified cookie sharing behavior across sites for users with Enhanced Tracking Protection set to Strict (Firefox defaults to Standard). Users with this specific browser setting and version combination may be unable to access the Amazon Connect CCP when embedded in another application, preventing them from handling contacts.

To prevent impact to your users (agents), we recommend that your users do one of the following:

1. Confirm (or set) Enhanced Tracking Protection as Standard in their browser settings. Users can do this by following instructions documented here.

1. Do not upgrade their Firefox browser version to v86 or higher.

1. Use Google Chrome or Microsoft Edge to access the Amazon Connect CCP.

That's how AWS is blocking firefox users to access the sound in a firefox browser. How to fix that?

Certain websites (see attached images) aren't loading banner ads or letting my view a site's gallery properly. This is only happening on Firefox - other browsers work fine. I have tried disabling extensions, Troubleshoot Mode, resetting my preferences, and changing settings that I thought would help, but nothing seems to work.

In the attached images, I have shown what I am seeing on Firefox, compared to what I am seeing on several other browsers.
