Firefox Community Forum

After a update 154.0.1 and 155.0.1, 64 byt Firefox dod not keep the open tabs once started, but the bookmarks. After searching in Firefox help, neither I could not find a previous bakup folder, before the update data, so I cannot restore the history it manually, so I do not know what to do. It is quite dissapointing as I had dozens of tabs open for diferent putposes, and now I have no one

Is there a way to remove "recent bookmarks" from the book marks pull down menu? Or at least hide them. It causes a total lack of privacy when any and all bookmarks can be seen in full view. Seems a stupid thing to not be able to hide them. Other browsers only show book marks when you go to the folder they are in.

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!

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!

I get several message that: I cannot connect to Amazon, Several websites, etc. It sometimes has something to do with private windows and/or can't connect! Could be license, ssl, etc. When I force a firefox private window, it works for a while then goes back to the same thing. Any ideas how I can fix this?

I get messages, questions and info from Firefox in Dutch. My language preferences in setting is English UK across the board. Browser, preferred, fall back and web site language. It works most of the time, apart from with Firefox. What can I do to make Firefox talk English to me?

In the Settings, the "HTTPS-Only" feature seems broken. There is an option to 'Don't enable" this feature, but that doesn't make any difference. I can get to an "http:" site using any other browser, but not with the latest Firefox.

I've searched & waited past few years for an Extension to make the TOOLBAR FONTS larger, none found. Reason being many of us are using larger monitors and TV's and we're usually sitting or standing further away from the screen. Problem is the font size cannot be changed, they stay small and hard to read comfortably. __YES I've reset my operating systems font size, that does not work in Firefox TOOLBARS. __Changing the "firefox/addon/theme-font-size-changer" has been eliminated by Firefox. __Changing the "layout.css.devPixelsPerPx" to a larger number increases the whole TOOLBAR. I just want the FONT size larger. __(someone suggested) NO, I'm not going to setup 2 monitors.

Sure would like this issue fixed. In the pix below, it has been done.

Hello,

I am having trouble with my Simple Practice connection static and video not functioning for my sessions with clients on Firefox and would like to have this remedied...Maybe I just need an update but looked under Settings and didn't see that option. Please advise. Thank you!

I am unable to open applications in Firefox. When I try to open an application, nothing happens or it does not load properly. I have already tried restarting Firefox, but the problem still exists. Please help me fix this issue.
