Firefox Community Forum

Firefox is not responding. Also various apps are not showing/responding. Apps I use every day have disappeared and when I go into the App Store and search for them they are not even listed.

Hi,

I’ve recently noticed that after a Firefox update, the browser has become very slow and unresponsive whenever I open multiple tabs, around 5–10. Before this update, I could open many tabs without any noticeable lag.

Now, new tabs take a long time to load, scrolling within open tabs feels choppy, and sometimes Firefox freezes for a few seconds before responding again.

I’ve already tried restarting Firefox, disabling extensions one by one, and clearing the cache, but none of these steps have improved the performance. I’m using Windows 10 and the latest version of Firefox.

Could anyone suggest what settings or troubleshooting steps I can try to fix this slowdown?

Spectrum recently updated their email systems and Firefox can no longer be used to check Spectrum webmail email accounts. I used to be able to go directly to the webmail but now they make you log into your Spectrum account to get to the email accounts and there is something about Firefox that is not up to their security standards. I am running Windows 7 with the latest Firefox that will work in 7. I am also running the Brave browser on Windows 7 and that works with the new Spectrum system. I prefer using Firefox over Brave so could you please correct whatever deficiency exists in Firefox to make it compatible with Spectrum webmail?

FYI, Firefox on my Windows 10 machine has the same issue.

I just had a firefox tab with a pop up asking me to try ai features... my options were "yes" or "maybe later". How do I stop the slop sales? I want ZERO pop ups... from Mozilla or anyone else! I didnt see settings that would disable mozilla sales pop ups - is there some way to turn these off permanently? I have already turned off the ai features. Really appreciate any suggestions!

On outlook.com sign in with password does not work. It gives "Please retry with a different device or other authentication method to sign in." Works fine in edge.

i have bit-warden, u-block-origin and stylus installed (but they shouldn't be running on the 'new-tab-page' - is my firefox sync-profile containing some firefox-breaking-errors? (latest Win-11)

When the Global Privacy Control request is checked (https://support.mozilla.org/en-US/kb/global-privacy-control?as=u&utm_source=inproduct) a persistent bubble appears at the bottom of the page indicating the request has been accepted. The bubble is annoying. Is there a way to continue to use this feature without the bubble appearing?

HI Since the last update from Firefox. I am experiencing frequent and multiple crashes. so much so I have beenusing google chrome as alternative browser. It would appear to me that the "new" version is unstable. = Version 147.0.4 (64bit).

Do I go back the the previous version? and if so where is it.

Hello, I am facing a strange issue while using Firefox browser. When I try to play LetterBoxed NYT, the game sometimes gets stuck on the loading screen or loads very slowly. The same website works fine on other browsers like Chrome and also on Android devices, so I’m not sure if this is a browser compatibility issue or something related to caching, cookies, or browser settings.

I have already tried clearing cache, disabling extensions, and updating Firefox to the latest version, but the issue still appears occasionally. Could this be related to browser security settings, DNS resolution, or performance optimization? Please guide me on what settings I should check or change in Firefox to make this web game run smoothly.

When trying to log into my bank, I get the following message: "Bad Request: Your browser sent a request that this server could not understand". I have tried to clear cookies, to no avail.

Every time I try to use my camera or microphone on some websites from on firefox it says can't detect camera or microphone? It doesn't show up with the 'allow this website to access your camera/ microphone' pop up it does with other websites. I went into permissions and manually changed it myself and it said it still couldn't detect the camera/ microphone

I have a weekly appointment in google meet. My main browser is firefox, and when I try to join there is no video available.

I have checked that my laptop camera works in general, and that google meet has working video on another browser, so the issue seems to be with the permissions google meet has for firefox.

Every time I join the meeting, there is the pop up which asks if I want to allow the use of my camera and microphone. I always click allow. Recently, even after doing this I dont have video footage.

The meet page does not say that my camera is off.

Firefox stores certain temporary data in a startup cache to improve startup speed. Clearing the startup cache and then restarting Firefox can sometimes fix various issues, such as mixed languages in the user interface after an update. This will not change your profile data or add-ons.
