Warum muss ich immer wieder die Surfdaten löschen damit ich die Seite meines Routers öffnen kann ? Nur dann funktioniert eigenartiger Weise mein Passwort. Es ist die Seite:http://192.168.8.1/#/home zu meinem Huawei B636 Anmeldung. Mein Firefox ist auf aktuellem Stand. Bitte um Info bzw. Abhilfe

Ive been FIGHTING to get business done on ROKU website. IT continues to switch to SPANISH. I am in the USA. I no longer am subscribed to ROKU in SPANISsince several months past. I figure a BLOCK for other languages would do the trick.IS there such a thing. THERE SHOULD BE!!! Thanks

System: Linux Mint 22.3 Xfce Firefox web-browser: mint-001 - 1.0 _ 155.0.1 (64-bit) Hardware: Both on my Desktop and Laptop computers.

Since the recent updates, 1-2 weeks, every time I try to enter a character via Unicode insertion, CTRL+ALT+U, the character does not insert but a row break. I made a video about it: https://youtu.be/OP9UCGpZdEc

This happens in every website I use; mostly likely on every website.

Is there anything I can do now?

Thank you for your time reading this. 🙇

Hello Mozilla Community,

We are experiencing an issue where our legal services web portal (hdclaims.co.uk) fails to load properly specifically for users on the latest version of Firefox on desktop.

Problem / Issue:

Users report receiving a SEC_ERROR_UNKNOWN_ISSUER error when attempting to access our online claims form.

The issue does not occur in Chromium-based browsers, but Firefox blocks the websocket connection required for live chat support.

Environment Details:

Browser: Firefox Desktop (Latest Version)

Website: hdclaims.co.uk

Server Setup: Nginx reverse proxy with LetsEncrypt / Cloudflare SSL certificate.

Steps Taken:

Verified intermediate CA certificates are properly chained on the origin server.

Tested with a fresh Firefox profile (no extensions enabled), but the security warning persists intermittent for UK users.

Checked SSL Labs report, which confirms an A+ grade.

Is there a specific cipher suite requirement or OCSP stapling configuration in Firefox that could cause this intermittent SSL handshake failure on .co.uk domains?

Any insights from the community would be appreciated!

I am on version 155 of the browser, and the sidebar is not showing up for me. Clicking the sidebar toggle button also does nothing. I've tried going into settings and toggling the show sidebar option, but that also doesn't do anything, as if the sidebar feature doesn't exist. Toggling vertical tabs just makes the tab bar disappear, and I've tried both the options menu and right-clicking the side bar toggle button. Is there an error, or am I missing something?

I don't know if the F/F updates are legit; I used to get updates, once in while.Lately seems updates are every few days or everyday.Not sure if these are spam or getting hacked?

I've always used Firefox as my default browser, it's been updated and is the current version. Recently I have noticed that pages are slow loading and some images on the page never load properly and remain blank. More vexing, is that Gmail has become very unstable in Firefox and won't load properly, loads slowly and freezes blanks out when I try to delete trash or spam, etc. It's annoying as more and more I have to open up Edge Browser to get performance on the websites that are failing in Firefox. This includes various websites that I use for work where logins are glitchy and unstable in Firefox, but work in Edge? Disappointing as I prefer to use Firefox, but even with recent upgrades installed it seems to work less well than in the past.

I want University Of The People student app restored on my new Mozila Firefox with Yahoo mail.com. I am a student and may drop out if I loose the contents I am asking for.

Hi Mozilla Support Team,

We are testing our commuter booking web application (carliftdubaitoabudhabiae.com) on Firefox for Android (v128+).

Our web app relies on real-time Geolocation APIs to show passengers their pickup points and Web Push Notifications for schedule updates. However, we are noticing a few technical issues specific to Firefox Mobile:

Geolocation Prompt Delay: When users open the booking map, the browser location permission prompt takes 4–5 seconds to load compared to Chrome.

PWA Service Worker Caching: After updating route schedules on the server, Firefox Mobile sometimes serves stale cached assets even after clear cache commands.

Are there specific Service Worker or Manifest configurations recommended for Firefox Mobile to ensure fast real-time location updates for transport web apps?

Thanks for any technical guidance!
