When trying to access the Tax Withholding Estimate at IRS: https://apps.irs.gov/app/tax-withholding-estimator it will not work in Firefox. I get this message: "Application error: a client-side exception has occurred (see the browser console for more information)." I don't understand how to interpret the console messages.

I get the message after filling out the "Information about you" page and clicking NEXT. Website works without issue in Google Chrome.

Is there a setting I have clicked in Firefox that is breaking the website or is the website to blame?

Using Firefox 128.6.0esr with no extensions installed.

I used the CSS animation property called animation-timeline , which is written as:

element{ animation-time: view(); }

When I view the webpage on Chrome, Edge, Opera, and even on Phoenix browser, the animation works.

It is only on Firefox that the animation does not work. I even added the Vendor-prefix of " -moz-animation-timeline " to the CSS property, and it still didn't work on Firefox, while it is working on all other browsers.

The CAN I USE website ( https://caniuse.com/?search=animation-timeline ) tells me that Firefox does not support it at all.

It however said that I can enable it, by setting "layout.css.scroll-driven-animations.enabled" to true.

1.) I don't know what that means.

2.) Would my website's users be able to see the animation on their Firefox browser, if we assume that I make this setting ?

3.) I am using Firefox version 138.0.3 (64-bit) : What can I do to see that both I and users of my website are able to see this animation on Firefox ?

Regards.

Why am I getting this message and how can I resolve the problem without switching to chrome?

I am encountering an increasing number of sites that don't work with Firefox but do work with Chrome. I have tried turning off add-ins without success. Is there a way I can easily reset Firefox to its initial state and then return it back.

I can no longer open my gmail in firefox. I need to open chrome to load my gmail and I never use chrome. So why can't I load gmail into my firefox account. Everything else is loaded except my gmail.

dunno if this is the right board, but here goes...

I discovered a bug with Firefox and the pen/touchscreen on my lenovo X1 tablet.

Using the touchscreen, move the map, map works as it should. Can pinch to zoom, ect.

Switch to the pen, map works with pen.

Touch the screen again and Google maps doesn't respond to touchscreen anymore, only the pen, and refresh does not fix it. I have to close and re-open maps in a new tab.

In chrome, this does not happen. Only in Firefox.

I am trying to sign-in to a site we use and when you hot sign-in the page goes blank white??

The site works on Microsoft Edge so I know its noit the site.

Please advise.

Windows 11 - 64, Firefox with last upgrade, https://www.flightradar24.com not working. Other browsers (Edge, Chrome) do not have this problem. Other pages Firefox open normal....

Whenever I get on YouTube the website will not completely load, If I restart Firefox and access the website it then loads completely. However when I click on any video it does the same thing as the included picture, however I can play the video, but I cannot click on anything. This only happens on Firefox, any other browser and I have no issue. I have also disabled my plugins and it does the same thing. I have tried multiple different suggestions from your help page and other solutions on the internet. If I could have some insight would be extremely welcomed, thank you and have a wonderful week.

I just installed Firefox on a new PC build and Twitch will load but just gets a spinning circle instead of playing the stream. The streams play fine on other browsers but i can't figure out why its lagging so bad/not working on Firefox. I did some digging and tried resetting cache and cookies and switched of recommended settings but nothing seems to work.

Ever since I updated last week, one website that I use will not work. Whenever I try to log in to the M&T Online Banking website, it blocks me and says "M&T Online Banking Is Temporarily Unavailable." The app works on my phone and I can log in through Chrome, it's only on Firefox that I'm getting this problem. I called M&T Bank and they confirmed that it's a problem with Firefox. Something is blocking me but I don't know what it is. I am not using a VPN or adblocker.

Firefox is no longer compatible with my bank's system. I can't log in with the secure access code the bank sends to verify my identity when using Firefox. The bank says it is a problem with Firefox. Other browsers work flawlessly ... are you working on a solution? I only use Firefox unless forced to use something else ...

When I try to access F1 TV, it says: "Unsupported Browser". "This browser is currently unsupported. To experience F1 TV, please switch to an alternative browser. Please see our FAQs for more information." (https://f1tv.formula1.com/). The problem started since about a week or so ago. I can't find any info on the the F1 TV site that gives a reason. Now I need to watch it on EDGE..... I don't like EDGE too much.

For several days I'm not able to log in at Facebook. Without login I can easily open Facebook from results via Google searches. The problem are seen when I try to log in using latest Firefox. Can log in via Chrome and Edge. Tried to disable all extensions but the problem persist. Using Samsung Browser in tablet works fine as well.

See attachment, where error is illustrated. It says: This page is not avaible right now. It is caused by a technical issue and we are working on a solution. Try to reload the page

Hope for some help here....

Hello kind Mozilla folks, I can't stream video through free Paramount+ account, (from Spectrum). Access set to Strict VPN turned off (is that neccessary? Spectrum sent me to Paramount+ for the issue. Paramount+ did get me streaming using Chrome. (yuck). When I get logged in to P+ and select watch now for a show, it doesn't stream, ...only a black screen. Would prefer to use Firefox/Mozilla. Have you had this isuue and/or can you resolve?

Best regards, Jay

Tried to file my Federal and State taxes using Turbo Tax which I have used for years. I am using the Turbo Tax on line app for Windows 11. Was unable to complete the filing because of many error messages. Turbo Tax tax experts suggested I switch to Chrome. I followed their suggestion switch to Chrome and was able to complete the filing of my Federal and States Taxes with no issues.

Why can't we use Firefox to file our Federal and State taxes?

Hello,

I apologize if the topic is incorrect, but I didn't know which applied to my situation the best.

Starting on Monday of this week (4/28/2025), YouTube no longer loads properly on Firefox for me. The entire page is covered in video slots with no videos and if I try using a link to a specific video, it will take me to the page, however the video will not load or play, additionally any other elements such as comments or suggested videos will not load. I am using the latest version of Firefox Developer Edition.

I have tried all of the following:

• disabling all of my add-ons
• clearing cache, cookies, and history
• uninstalling and reinstalling Firefox
• logging in and out of YouTube
• Reaching out to YouTube (they told me to just use Chrome)

I have asked my friend who also uses Firefox and YouTube works fine for him, so I'm not sure exactly what is making it not work.

Thank you for your time!
