When signing in to online Shaw Webmail, message says 'Security Check Failed. Clear your browser cache and retry'. Screenshot attached. Have done so in "Clear browsing and data history", (as per Firefox guidelines) multiple times, for all History and cache. Did not resolve issue. Contacted Shaw Support; they instructed to try logging in with Chrome browser. Worked fine. Issue appears to be strictly with Firefox Browser (on multiple devices). I prefer Firefox over Chrome. Any advice greatly appreciated.

Hi,

I started using the 'Vertical tabs' option to manage my tabs. I prefer it over the horizontal bar. However, I noticed that when going fullscreen (F11) the vertical tabs are not removed. This is different from horizontal tabs, which are removed from the UI when you press F11.

I think that's because vertical tabs are tied to the sidebar altogether. Is there an alternative to have the vertical tabs work the same as horizontal tabs?

Horizontal bar behaviour in fullscreen:

- The horizontal bar disappears when going fullscreen (F11) - The horizontal bar reappears when hovering the mouse over the top of the screen (which is great!)

Vertical bar behaviour in fullscreen:

- The vertical bar does not disappear and gets in the way of the fullscreen (F11) experience - Checking the setting "Expand sidebar on hover" does not replicate the behaviour of the horizontal bar reappearing upon hovering the mouse. Instead, the smaller version of the sidebar remains and it expands to it's full size when the mouse hovers over it - The only option is to remove the sidebar altogether, which means going back to horizontal tabs

I had switched to Firefox from Chrome because they banned AD BLOCKERS. But now I have to go back because FACEBOOK VIDEO CHAT won't work ( according to Facebook) because they introduced end-to-end encryption. Can you give me a fix?

Hello, I have just upgraded to windows 11. On firefox I used to be able to right mouse click on the firefox icon in the taskbar to select my saved saved (Pinned) websites. In the past with Windows 10 I right mouse clicked on the url of favorite websites then drag and drop on the firefox icon in the taskbar and that was it. On Windows 11 that no longer works. How do I pin my favorite websites to the firefox icon in the taskbar on Windows 11? I thank anyone for your help.

Hello:

I'm not certain if this question comes under Firefox or not:

How do you stop a specific computer software program-app pop-up notification (popping out from the lower right corner of your computer)?

As an example, I have a utility program, IOBIT Malware System Care that pops-up various notifications such as "update notice," "renew," "discount sale" or whatever notice or ads that is 'pushed'.

-I went to my Windows 11 list of installed app "notifications" and this program is not listed. -I tried contacting tech support but they haven't responded. -I went to Firefox 'Settings' -> Privacy & Security->Permissions and then I opened up 'Exceptions' to see if I can block something. It wants me to put in a specific website. The issue is not a website but coming within a software / app program.

So how and where do I stop a "pushed' notification? I assume it's coming in via my browser / Firefox?

Thank you in advance,

Steven

Mozilla Firefox 115.25.0 (x64 en-US) won’t close since my previous version was updated on 6/29/25. I have tried closing it in my Win7pro Task Manager on several occasions, and had even tried to uninstall and then reinstall it from my “Programs and Features” menu, but I keep getting a message that the program can’t be uninstalled until it is first closed. Nothing I do fixes this problem. HELP

the website onodreamgallery.com shows up as Under Construction, yet on another browser it shows correctly. I do not know how to fix this; I am not versed in Internet language.

Hi Mozilla Community,

I’m facing an issue where my website, [malicious website removed], is not loading properly when accessed through Firefox. It either takes a long time to load or sometimes fails to load altogether, even though it works fine in other browsers like Chrome and Edge.

Could you please guide me on what might be causing this issue? Are there any specific Firefox settings or known compatibility issues I should check? Any troubleshooting suggestions would be appreciated.

Thanks in advance for your help!

Hello Firefox Support,

I’m encountering a strange issue with Firefox. While playing YouTube videos at very low quality (144p) just to listen to music, my GPU usage spikes to 100%. This happens even when the video is not fullscreen and there’s minimal visual content.

System Info:

   Firefox Version: 140.0.2 (64-bit)

   Operating System: Windows 11 

   CPU: AMD Ryzen 7 8700F (no integrated GPU)

   GPU: AMD Radeon RX 7900 GRE

   GPU Driver Version: AMD Adrenalin 25.6.1 

The issue goes away when I disable hardware acceleration in Firefox settings, but I’d prefer to leave it enabled for better performance elsewhere.

Is this a known issue with AMD GPUs or is there something else I can try to reduce GPU usage during playback?

Thank you for your help.

Firefox has just introduced wallpapers for browser home page. I cannot get it to work. It's either cropped too small or pixilated, is there a setting I need to adjust, or a particular image format? So that it looks ok.
