When I open a .jpg file, the Firefox web browser window width is too big. I want to change the default window width. Which item in about:config controls this setting and what value should I enter to have a default window width of approximately half the screen size?

Hi,

In the older Firefox version (92), I could instantly open JNPL files by selecting "Open with Default Use JAVA (TM)". However, in the latest Firefox version 127, while the option is still available, it doesn't instantly open JNPL files. Every time I have to click to open the JNPL file.

Hello. I got a new pc and I am trying to sync my Mozilla account right now but I am not getting a the code to my email so I can not login to the account. The mail in question is *@cock.li that I have all my old data on.

Most tabs that I open now crash. This has been a steadily building problem that now has made the system basically unusable. I did try clearing history, cookies, etc., but that did not help. Even working tabs can crash when I go back to view them. It doesn't matter if it is a saved site, or a brand new one typed in.

I've been using Firefox for years on Windows 10 and earlier, and I just got a new Windows 11 laptop. On the new machine my bookmarks sidebar doesn't persist. I launch Firefox and open it, but when I exit Firefox and launch it again the sidebar is gone. I have to re-open it every time. This is not the behavior I experience on my other machines. Is there a setting in about:config that I need to change?

Hi,

It's been a while since this problem first occurred but I am now very sure that this is about Firefox and not about graphics driver. This happens both when the hardware acceleration is turned on and turned off.

When I open a website that has mainly images or videos, the browser goes blitz (Reddit, Twitch, etc.). Screen splits to multiple views, it starts flickering and continues until I switch to another tab or quit Firefox. For flickering to stop, I need to restart the computer. I can also send a video if you can communicate a proper way of sharing. (Drive link, youtube, etc.)

Is there any way I can ensure Firefox does not break things on my computer?

Thanks

Just starting up Firefox on my Windows 11 desktop initiates 9 firefox processes - see attached. Is there anyway to reduce the number of processes and the memory they seem to occupy by possibly going into the Windows registry and making changes to any Firefox configuration settings? If I dont get a satisfactory solution I will have to uninstall Firefox and use the default MS Edge which is not my preferred browser choice.

I use Firefox Nightly 131, because it have vertical tabs, but why you still have a empty top bar? can I hide it?What's the difference between that and horizontal tabs? It takes up just as much space.

I have a subscription to the FAZ and have always been able to read it in Firefox. Now that I have a new computer with the latest Windows 11 and the latest Firefox, I can no longer open the page https://zeitung.faz.net/. But it works fine in Google Chrome. Please tell me which settings I need to change so that I don't have to change browsers.

I was working on a work site and every time I wanted to delete an item a pop up would appear asking if I wanted to confirm deleting. I was tired of confirming and there was a box offering to stop the pop up. I clicked it and now I can not delete anything. I checked settings and added the site to allow popups that did not help. How do I fix this?

I am not part of an organization. Despite that, my browser is being controlled by an organization and I cannot control how my browser operates. I have uninstalled and reinstalled Firefox several times to try to eliminate this issue and it keeps returning. There seems to be a certificate associated with this problem. "ImportEnterpriseRoots" How do I get rid of this problem permanently?

irefox detected an issue and did not continue to khulna.land.gov.bd. The website is either misconfigured or your computer clock is set to the wrong time.

It’s likely the website’s certificate is expired, which prevents Firefox from connecting securely.

What can you do about it?

khulna.land.gov.bd has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

I get the following notification: Secure Connection Failed

An error occurred during a connection to nz.mail.yahoo.com. Peer’s certificate has an invalid signature.

Error code: SEC_ERROR_BAD_SIGNATURE
