My Firefox shortcuts keep disappearing: this is an almost daily occurrence. Sometimes they re-appear later without any intervention, sometimes they re-appear after a reboot. Right now, after rebooting and 'fixing' Firefox from Control Panel, they are still missing. I have 4 rows configured for both shortcuts and recent sites, and had 'pinned' about 20 shortcuts. Currently on Windows 10, soon to upgrade to Windows 11.

Can someone PLEASE tell me if there is a fix available for this (will it be resolved in Win 11?), or if there is a way to easily save and restore these backups when this problem occurs.

The ability to have 32 shortcuts is the motivating reason for my using Firefox over Chrome or Edge (which only allow 8), but if they keep disappearing like this I'm going to have to re-think my browser selection.

Thanks for any suggestions.

Why can't Firefox open .mht email extensions within its default browser? It has never done so to my knowledge. They always point to Internet Explorer or Microsoft Edge.

Often an email may not display images correctly and the ability to open them in a web browser is offered, "If there are problems with how this message is displayed, click here to view it in a web browser." This is certainly a development addition when people view their Gmail from Firefox or use Outlook. Not everybody uses APPS. People who don't want Microsoft Edge watching every move they make have made effective permanent changes in removing the deep embedded PUP by Microsoft.

Firefox version: 148.0

I have three failed downloads that are stuck on the list. Retrying them does nothing, and deleting them does nothing.

Incidentally, the images that those failed downloads link to are online and available.

How do I get rid of them?

Not sure but I read that windows 10 has reached the end of support in oct. 2025. I have no idea what book marks I had because My friend put them in for me. I do not know why firefox or windows had the rights to chage my computer and I do not have the funds to buy a new windows 11 computer. So bottom line what can I do to fix this issue

Many websites that I use regularly, such as Zillow, no longer work correctly in Firefox ESR (115.33.0). The top menu in Zillow disappeared this week. Others work, but all the text is greyed-out. All except the text thing seem related to Javascript features. For instance, check boxes on a Wordpress site that I manage quit working last month. Some, like www.RCgroups.com just sit and spin, and never fully open up.

But they all work fine on an old copy of Chrome (109.0.5414.120), that is no longer supported on Windows 7 and hasn't been updated in probably 3 years.

My only plugin is NoScript, but the problem is the same whether it's turned off or not. And I also use NoScript on Chrome.

I use Win7 for the same reason I use Firefox -- it is safer, far more stable, faster, and it doesn't force updates on me that invariably break things. I appreciate that Mozilla has extended support for the last stable version of Windows. But somebody should look into this growing compatibility issue.

i noticed every websites that i visited or some links just suggested are appeared in my firefox homepage i selected only shortcuts in setting which i expect to see only shortcuts that i added manually but its just more shortcuts pop up each time i open the new window on my home page this is really annoying and , its not necessary at all , i dismissed them manually but they just pop up again please can you report this issue to be fixed on next release ?

On my first PC, I have this specific sidebar icon in my toolbar. When I click it, the sidebar opens with Gemini ready to go. Perfect.

But on my second PC, that specific icon is nowhere to be found. Even when I go to "Customize Toolbar," it’s not in the list of available buttons. The only thing I can use is the generic "Sidebar" button, which is annoying because it doesn't open Gemini directly, it just opens the general sidebar and I have to click again.

I provided an image, where the first icon is what I want, but only second icon is available.

thanks for looking into.

Hi everyone,

I’ve been testing a simple online click counter to track clicks and sometimes test my clicking speed. The tool works fine most of the time, but in Firefox I noticed that after refreshing the page the counter occasionally keeps the previous number instead of resetting to 0.

This is the tool I’m testing: https://thetallycounter.com/

I’m not sure if it’s related to Firefox caching or local storage behavior. Has anyone experienced something similar with web tools that store values in the browser?

Would clearing cache or disabling something fix it, or could it be a Firefox-specific issue?

Thanks!

Back again with another question related to flightrising

there are familiars displayed next to the dragons, some of them are supposed to change their pose automatically, but for me they only change when I click on the familiar it works on other browsers, and on firefox for windows, so I guess it's something in about:config, but I have no idea what I'm doing, so I'm hoping someone here can help me figure this out, because I'm not about to mess around randomly

link to a page with a familiar that's supposed to change: https://www1.flightrising.com/dragon/80217294

pretty sure it's obvious what I mean by transform, and what I have to click on to get it to move, but I'm posting the pictures illustrating the change anyway

Watching a CNN video on YouTube Firefox suddenly freezes and does not accept any further actions. Even shutting down it will block the process and I need to use the "Shut down anyway" function. Similarly, Thunderbird will lock up in the middle of writing a response, but here it is just the window and I lose what I typed, but I can go back and push "reply" again and retype the answer. Whether these are down to similar issues I don't know. Obviously, this sounds like a graphics driver, so I made sure all updates are installed and there is no further update available for both, Firefox and Thunderbird as well as the system drivers.

Any pointer is appreciated as this is really annoying. Thanks

How to make Firefox my default browser on my new computer a Windows 11 computer. I’m to the point where I’ve got a pop-up window, which says sync Firefox on your phone or tablet. I am asked toOpen Firefox on my mobile device. Then Go to the menu and tap sign in. That’s where I am. Now I’m asked to tap “ready to scan” and hold my phone over the code. Unfortunately, my Firefox app does not show a ready to scan option after I get to sign in. Help!!
