Where is the configuration setting that enables javascript. Consumer Reports requires that the application be enabled to participate in a webinar I want to attend

I have these printers.

"HP LaserJet M109-M112" (the Windows default) "HP LaserJet 1020"

Regardless of the value of print.sav_print_settings, the first print dialog after starting Firefox shows "HP LaserJet 1020".

If I manually put "HP LaserJet M109-M112" (no quotes) in print_printer, it reverts to "HP LaserJet 1020" the next time Firefox starts.

How do I make "HP LaserJet M109-M112" Firefox's default? Thanks.

These icons appeared recently in my Firefox browser I can't remove them. The only recent changes included uninstalling SuperAntiSpyware after finding that Microsoft PC Manager is a better option, which has performed excellently without issues.

Additionally, a free VPN (Proton) was briefly used from the Firefox browser without installation, but after finding it complicated to set up, it was deleted. A few hours later, I noticed the two icons as the windows were misbehaving and they are causing a slowdown in the PC's performance. They do not seem to be add-ons or extensions.

How do I remove the icons and return to the previous performance?

I would like to eliminate the websites which are done by an AI in my brownser. Especially those were no redactor is mentionned. Is it possible ?

Thanks

I've noticed that Youtube videos on Firefox are far more washed out when compared to Google Chrome. HDR is enabled on my Monitor and in Windows 11; however, the issue is present for standard SDR videos as well. Any idea what is going on here?

Suddenly I cannot log into icloud from your browser. I can log in using other devices and other browsers. Fire Fox gives me an error message "Failed to verify your identity. Try again"

I am intermittently but repeatedly getting this message in Firefox:

> The Windows file-dialog has crashed. No file or folder could be selected.

Windows 11, Firefox 142.0.1 Most recently within www.facebook.com Edit Album

Is this a known problem? And does it have a solution?

I'm using the AI chatbot in Firefox Developer Edition's sidebar and I was wondering if it's possible to set the web page from the active tab as the context by default for all future chats.

Is there a setting (checkbox) for this somewhere?

I have two websites of my own. I am viewing one and it is correct. When I view the other, it uses the https cert from the first one, and says my site is not secure. I have viewed the cert, and it is definitely correct. I think Mozilla is probably caching old information - the certs have been correct for most of 2025, so it is a pretty old version. Therefore, it is not actually caching the cert, but caching which cert it should use. I have tried clearing the cache, and it did not help!

Has Mozilla got some kind of cache I can't clear? Should it not re-read the cert when it loads the site, or at least the cert date, each time it reads the site (ie was not previously showing it on screen)?

Old lenovo laptop put a small dot by firefox symbol when an update was available. New lenovo isn't. Need it to keep running smoothly. Cannot find where to add that in. Could you please direct me? Thanks, Susan B Parvey

Greetings everyone,

Earlier, when I opened Firefox it didn't restore the tabs and windows I had been using from about 2 weeks ago. I tried looking in "History" in the Firefox menu but it only displays tabs and windows that I've closed and it doesn't have the tabs and windows I had actually open.

I've had the same Firefox settings since I first installed Firefox a few years ago and this is the first time this has happened... :'( :'( :'(

I must have had about 70 Firefox windows and even more tabs within those windows so this really hurt me... :'( :'( :'(

Thank you for any help!

Hello-

I have an issue with secondary webpages disappearing. Occasionally, when I am on a website, particularly when I am buying something or comparing items and a pop-out page appears showing what you selected, when I go to click on that 'secondary' webpage it disappears. It's not hidden between other open browsers or appearing on the taskbar. It's just gone. When I go back to the main webpage site and open up this pop-out page again, it will reappear. But the moment I click on this pop-out page it disappears. An example is attached with a DoorDash progress order. It seems that it only happens with "secondary" pop-out pages. It does not occur if the website creates a whole separate new non-pop-out page.

I went into settings to try turning off and on pop-up to see if that does something but nothing. Thanks for your help in advance.

A repeat of a problem I was having a couple of months ago. I go to the reddit website and login with no problems but when I try to comment or load specific threads I get the attached warning come up:

"! Your request has been blocked by network security. Please try to login with your Redit account."

Which doesn't make sense as I'm already logged in. Last time it seemed to clear after 24 hours or so although not because of anything I did as far as I'm aware.

1. Started Firefox in Troubleshoot Mode - problem remains … 2. Cleared Firefox Cache/Cookies and restarted Firefox - problem remains … 3. Shutdown and restarted iMac - problem remains … 4. Problem not happening with Safari or DuckDuckGo browsers … 5. Checked macOS Local Network security. Firefox has access but turned off access and turned back on, restarted iMac - problem remains …
