I am using Firefox desktop on Windows 11. I have downloaded hundreds of articles from this website, with no problem until yesterday. I accessed the website using Edge, and it worked fine.

When trying to access a particular article to download it to Ancestry, the following message appears:

Application error: a client-side exception has occurred (see the browser console for more information).

I accessed the browser console for more information, which I'm sure someone can understand, but not this grandma. This is what I got:

I really don't want to stop using Firefox, but I need a usable browser. Can you help me?

Non-removable settings? "English (GB)" language and "Autoplay -> "About:Welcome" -> "Allow Audio and Video"

Hi,

Looking at my Firefox 147.0.1 settings for macOS 26.2 (Apple M1), I'm trying to adjust two settings:

-- I'd like to remove Languages -> English (GB) (its existence has odd side effects, like triggering United Airlines to offer fares in Pounds Sterling, and I'd prefer to just have English (US))

-- I'd like to disable Play Audio and Video for about:welcome (in regular and private windows)

I can see no way to accomplish this currently -- why?

Thanks.

Captcha

Im not sure why but I'm asked to perform a captcha every time I open a new tab. Not sure why, but its quite annoying, only occurs on my PC not on mac or phone.

Firefox 139.0.1 (64-bit) on Windows 11

I occasionally increase the zoom level of websites (usually forums) with Ctrl+mouse wheel if the default text size is too small. However, if I forget to set them back to 100% (Ctrl+0) before closing the tab, the next time I open that URL, it's at the former adjusted zoom level -- not 100%. Really annoying.

How do I force Firefox to open all URLs at 100% regardless of the last custom zoom level? I have default zoom already set to 100% in Settings and Zoom Text Only is not enabled.

Thanks.

Even though my settings in Firefox are set to restore open tabs when restarting, and Firefox is my default browser, I was unable to restore my open tabs when my Firefox browser just closed on me. I went up to the menu > History > Recently closed tabs > Reopen all tabs and nothing happened. Is there anything else I can do? Thanks for your help!

I have my FF preferences setting as "Strict". But somehow Facebook people were able to hack into my FF account, and obtain my password for FB and other passwords? This comes directly from my Firefox preference page Red Warming Box includes & states on Sept 30, 2025 Facebook Hacked & Gained access to my account. Not a person, it states Facebook did it. And to change my FB password ASAP. So I go to my FB account go through their lame motions and they say they will not allow me to do so because I haven't used my account very long and they don't know if it is me trying to change my password. My question is what do I do now and how to prevent any social media outlet of simply hacking into my Mozilla account or my Firefox accounts? Please help. Seems like their should be a law against this type of intrusion gathering save password and etc.

I'm simply trying to email someone using the email link on their site.

The link is a mailto link which requires an email application (which I don't have). All I want is to copy the link to the clipboard.

Firefox lets me right click the link and copy the email address, but this doesn't allow me to provide the required Subject specified by the site's author.

I could have sworn Firefox used to have this feature. Netscape and IE certainly always had it back in the day.

Installed Firefox on my laptop. Already running on my desktop.

Whenever I try to open a link, I get: Get an app to open this 'microsoft-edge' link

Your PC doesn't have an app that can open this link. Try looking for a compatible app in the Microsoft Store.

Is this Microsofts way of saying "Use Edge?" Can I change settings to make it work?
