Hi, All of a sudden, I lost absolutely all of my bookmarks. My PC is running Windows 11. My Firefox account was and still is logged in. At first, I thought the data loss was due to a CCleaner cleanup using their latest update. After the data was lost, I tried running another CCleaner cleanup, but this time it didn’t delete the bookmarks. So I honestly have no idea how this could have happened. These were bookmarks I had saved over many years... It’s a disaster.

I am 81 years old, ad not a tech genius, but I can no longer access my memory photos that microsoft one drive sends me every day. It did work before, but now I get a blank screen. Microsoft help tried the edge system, and the pictures came up, but on firefox, I now get a blank screen. I do not want to change browsers

Every couple of days I am unable to access my email accounts, facebook and most web pages.

The only way I can access them is to refresh Firefox after which all work OK.

Really like firefox but am getting fed up of having to refresh it constantly any advise you could give would be very much appreciated.

When trying to access many popular websites with Firefox on my Fedora 43 installation, I am greeted with a security warning page with the SEC_ERROR_UNKNOWN_ISSUER error. For most of these websites I can simply accept and continue, but HSTS-only sites will not permit this.

Affected websites include but are not limited to (based on exceptions in the certificates section of Firefox settings):

• github.io (many subdomains)
• purdue.edu (many subdomains)
• iu.edu
• ebay.com
• cbsnews.com
• iwm.org.uk
• home.cern
• celestrak.org

Any help in resolving this is appreciated.

Yahoo Finance stock charts are not loading. Never encountered this problem before this week. A GeekSquad tech support person was not able to fix the problem and recommended I contact Firefox. Edge and Chrome load Yahoo Finance stock quote sites just fine; I'm only having trouble with Firefox. Any ideas on how to fix? Thanks! Carol

I wanted to synch my current settings in my browser to import them on my new laptop. When I tried to login to my account, I the message from the attached screenshot appeared. So I created a new profile, got my stuff back to what it should be and then deleted the "new" profile. But now every time I try to get into the correct profile and login into my account, I still get the message from the screenshot. I never ever synched with another profile before and never had an issue in the past. Right now I am rather pissed off, because I lost atleast some of my bookmarks during this whole ordeal.

I really appreciate this amazing new 'unloading' feature. It's just the function I need. However, I can't unload all the tabs I've selected. Only some of them are inactivated, and this problem occurs almost every time I choose a group of tabs.

We are unable to stop playback from the controls in the PIP window for Apple TV when the video playback was started in the main browser window. If we press the control the playbacks stops for a fraction of a second and continues again. Other controls like mute etc. are working as exspected.

If we start the playback in the PIP window we are able to stop it!

If we use Youtube or Amazon as a video source the problem does not show.

If we use Troubleshoot Mode we get exactly the same behaviour.

Any Ideas?

The disabled feature still has a picture in the picture when unchecked. How do I stop picture-in-picture for videos playing in Firefox? Yes, went into settings and unchecked picture in picture, yes, the problem still exists.

I have various shortcuts saved on the shortcut page comes up after logging in. Its set to 2 rows.. I use it every day. Used it this morning and working perfectly. Been out and when I came back the page is totally blank. I've tried sytem restore to 5th October but makes no difference. I use Windows 10 and read that Firefox are continuing to support Windows 10 I'm visually impaired and use a desktop PC with a large screen. I'm not PC techically knowledgeable. How do I restore my shortcuts or how do I re create them?

Hi, Since the last update for Mozilla on the laptop (updated on 6/Oct/2025 - version 143.0.4 (64-bit)), all the shortcuts to websites in Firefox homepage I had pinned have disappeared. Also I can't add new shortcuts. I already have shortcuts enabled in Settings>Home>Firefox Home Content>Shortcuts.

Does anyone know how to solve this?

Kind regards.

I have unchecked search suggestions in settings but these still appear when I search in Firefox with Google (for which I have disabled trending searches).

What is the point of the setting if it doesn't work?

FIrefox 143 appears to prepend a google link to some links when clicked ... ...

… … and then after a delay load the page with the correct link.

This appears to be something new (or never noticed before) after my MAC OSX upgrade to 26.

Can't tell who's problem it is but it's annoying. Have to try other browsers to know if it's just firefox.

Any insights would be appreciated.

I'm not able to uninstall PWA apps created in Firefox 143.0.1 using Windows 11 usual uninstalling procedure. If i click "uninstall" in Windows Start Menu the app remains installed. PWA apps created with Firefox do not show on Windows 11 installed apps list so I cannot uninstall them. I haven't found any guide on the web on how to uninstall PWA created from Firefox. So, how can I effectively uninstall those PWA apps? Thank you in advance for your kind answer. Regards.
