Firefox Community Forum

Hello, I am working on improving the user experience (UX) for the website Sportzfyapp.co, a sports-related platform, and would appreciate some suggestions on how to enhance the site specifically for Mozilla Firefox users.

Are there any best practices for optimizing the following elements on Firefox?

Performance and load times: Ensuring fast loading speeds. Responsive design: Best approaches for making the website work seamlessly on desktop, given Firefox’s varying display behavior across devices. Accessibility: Ensuring the website is fully accessible for users with disabilities, including proper keyboard navigation, screen reader compatibility, and clear UI elements.

Any advice or insights would be greatly appreciated!

Thank you!

When I'm typing something in my searchbar which doesn't locate to a direct website. This error appears. It doesn't appear while googleing from the google website. I couldn't find something like mysearchengine on the computer and this seemed to appear out of nowhere. I'm using firefox for half a year now. Do you got any ideas what's causing this and how to fix it?

After an update to Win11 24h2 and every time I open Firefox a message (attachment) appears and I can't do anything. I've already uninstalled the app and reinstalled it and it still doesn't work.

Hi. I'm trying to troubleshoot failure to resume a download in Firefox and I want to see the HTTP headers just like in Network Tab of Dev Tools, but I can't find how to open Network Tab from the "Downloads" list. Is it even possible?

Normally, if I were to close a tab while using a regular Firefox window, I could use the Ctrl+Shift+T hotkey to bring that tab back again. However, if I do so right now (for example, Wikipedia's Mozilla article), I will not bring that page back but instead an older, longer-closed tab from some days ago. I can keep trying to close and reopen tabs, or just keep reopening tabs, and I will continue to dig up older and older tabs from longer and longer ago.

Is this a known issue, what might have changed that behavior, and how do I restore the expected functionality of tabs correctly being reopened in the reverse order that they were closed?

hi , i have an issue when i browse the website g-portal.com when i try to enter my account setting for my server the website shows me an error "value.toString is not a function" i contacted the website customer support and they advised me to try another device, it worked but when i try on my device on firefox i get the same issue

Hi ! I am using the latest firefox on win11 (latest updates). Since approx 2-3 days whenever I try to comment on youtube or edit an existing comment I cannot see what I am typing. I can still type and commit, the comment will appear and I it will contain what I typed. But when doing it initially it is invisble to me. If I reply to a comment I can see what I type.

Below 1st image shows a comment box I am actively typing in. Everything is invisible. 2nd image shows when I open a reply, you can clearly see the prompt and when I start typing it shows my input

인터넷 웹 사이트를 보다 보면 어느 순간부터 동영상이 재생되지 않음. 주로 mp4 인것 같고, youtube 는 여전히 재생 가능함. 화면이 초록색, 혹은 검은색 등으로 반응을 하지 않고, 재생되지 않음.

개인적인 경험으로 유추해 보길 탭을 많이 열면 그런것 같음. 탭을 많이 열면 50~100 혹은 그이상도 열긴 하는데 한번 영상 재생이 안되기 시작하면 껐다 켜기전까진 계속 재생이 안됨.

혹시 설정에서 뭔가 수정해 볼 수 있는 방법이 있을지?

Firefox abruptly stopped working on my MacBook Air. When logged in as the admin, Firefox works fine. When a 2nd user logs into an account on the Mac, and tries to open Firefox, Firefox asks to install a helper tool. If I do so (with the admin credentials), the helper tool prompt goes away, but then if I click to open Firefox the icon just bounces and I get an "application not responding" warning.

I have tried refreshing Firefox from the admin account. I deleted Firefox and deleted all user profiles, re-installed Firefox, and still the same thing happens (works fine on admin account, does not work for any other user on the Mac). I am also unable to open Firefox in troubleshoot mode (option key). Even with the option key the Firefox icon bounces on the dock and never opens.

I can't share any data because I can't open the app.

Any help would be appreciated.

Thanks.

I love Firefox, but I can't find an answer to why the keyboard input lags 5-10 seconds. This is always noticeable in NYT Games like Wordle, but not Bluesky, for instance. I use Chrome now for NYT but eventually I'll go back to stay if I can't fix this, which is a shame as it's the best browser around. Thank you for your help.

When you go to the YouTube community tab, click on a link like https://www.youtube.com/post/UgkxFmoD_WE2uSNmIHw1Njhj36JVQMnzrWzz this example I get a banner that this page slows down firefox and after a few minutes the tab crashes. I tried disabling extensions, but it didn't help me. I came across this on two different PCs on Windows.

When I use the Firefox browser, the use of this site is very slow, messages do not appear, and the site is horribly slow. Facebook also has the same problem. Please fix this problem.
