Trying to not just edit a PDF in Firefox on Linux but actually edit the document using its Dynamic-XFA format elements of that PDF. XFA is an Adobe proprietary format that they depreciated several years ago but it still works in Adobe Acrobat Free. (I use a Windows guest VM for this as a workaround for now but I'd rather not since it takes extra resources and time). Elements can be filled in FF and some menu drop downs work in FF but other dynamic XFA element buttons don't respond like the one I attached.

In Acrobat the "X" and "Add Contact" buttons will add or remove some elements to the document.

Can this be done in FF desktop?

Version 151.0.1 (64 bit) on desktop PC.

In about:config I know there are a lot of options to modify under the search term "pdfjs" but I don't know what element would allow this to possibly work if its supported.

I wish I had other better options but government documents are what they are.

Don't know what happened but suddenly the VPN icon got huge after an update to FF151. It may have happened after I installed Nightly. Don't remember. Any idea how I can fix it?

I am running the latest public stable release of Firefox, 151.0.1 (aarch64), and these last few weeks I've been getting prompted to grant my location over and over every time I do a Google search. In MacOS, I've granted Firefox location permission and I've repeatedly saved me giving google permission but it doesn't stop. This is happening on my MacBook Pro and Mac Studio.

Anyone else? Any tips? It's maddening. lol

I run Win10, and Firefox recently updated. I use https://partners.titantv.com/default.aspx as a TV guide for my Hauppauge TV tuner card. When I click on a program I want the PC to record, I click the red dot, which creates a program.tvpi file in my Downloads folder (see image attached). Up until recently, this type of file was associated so that clicking the red dot would automatically put it into the Hauppauge recording queue. However, the latest Firefox upgrade took that association away. So, now I have to double-click the program.tvpi file in the Downloads folder to activate it. Is there a way to re-associate it? I tried right-clicking the red dot, but there's no choice. I didn't see it in the Firefox, Settings, General, Applications feature. Thank you for the help.

Webgl has completly broken after last update for me. Forcing webgl in about config doesnt work and it doesnt work in troubleshoot mode either. Anything else i can try apart from reinstall from scratch as im worried about losing my history,saved account info and such. Or do i just need to do a full refresh and install? Thank you!

Hello, Im using localized (Lithuanian) version of Firefox. Several updates back, Firefox started including russian and Polish in preferred languages by default. Personally i know how to remove those for myself. However, since im managing around 300 computers in a school. This starts to become an issue. In Lithuania we only have one official language. And when pages in a school start opening in foreign (russian) language this starts to be quite annoying. I would love to keep using Firefox but i need help.

Privacy Policy from TD Bank (https://easyweb.td.com) appears at the bottom of every page change, no matter if "Accept All" has be selected. Moving from one account to another causes this pop up to appear. This does not happen with Chrome. With Chrome, one "accept all" has been chosen, the pop up no longer appears

If I turn off Enhanced Tracking Protection the problem seems to stop.

Bonjour, Avec le VPN je n'accède plus à ma banque en ôtant le VPN également (pas de souci avant) le message est:"verfying your browser before proceeding" voir la capture d'écran, Je n'y accède difficilement que lorsque je passe le VPN par la France. Pouvez-vous m'aider? Par avance merci. Valérie.

Hello, https://www.so.energy/myaccount/usage shows a vertical bar chart representing electricity usage over time. If I hover the mouse pointer over one of the bars in the Edge browser I see a pop up that gives details of the electricity use represented by the bar. If I do the same in Firefox the bar changes colour to indicate it has been selected but there is no pop up. Is there likely to be a Firefox setting that is preventing the pop ups from showing? Alan.

Hi there, while the built in vpn is working perfectly fine on my windows workstation, i miss the vpn button in the top right corner of this M1 Air. I tried the advised procedures, but there is no vpn button in the toolbar setup. My system uses Little Snitch as firewall. Any help would be appreciated.

Hi!

Some time ago I signed up for the early access of Smart Windows Beta (it was still referred to as AI Window at that time). A couple of weeks ago I got an email saying "Smart Window Beta is ready for you to try". However, when I click on the "Try Smart Window" link (clicks.mozilla.org/...), I get to a page that says "Join the waitlist" and I still do not have the feature available in Firefox.

• I am on Firefox desktop on Linux
• My Firefox version is 151.0.2
• I am signed into Firefox with the same email address as I signed up for the early access with
• I do not have "Block AI Enhancements" enabled

The entire browser was acting extremely slowly, on every website, every start up. It crashed constantly to the point it was unusuable, it was even affecting the performance of the rest of my pc so I reset it and everything I had on the browser disappeared. Bookmarks, passwords, etc. I've tried going through the profile support pages but only the profile made from the reset exists. I had years worth of important bookmarks and passwords that'd I'd like to be able to get back if that's at all possible. (I'll live without them, it'll just suck trying to remember them all again) PC is Acer Aspire 3 Spin 14, Windows 10

Why isn't there a simple means to remove/prevent searches for the address bar, using config doesn't work.

I've used Firefox for over twenty years, this annoyance will end that and force a move to Brave.

To the Security and Privacy Compliance Team: I am formally reporting a severe security breach affecting my account(s) and digital environment. Despite strict adherence to security protocols—including the use of two-factor authentication (2FA), non-reused/secure passwords, and active monitoring with Malwarebytes—my environment has been consistently manipulated by unauthorized automated processes. Summary of Compromise: This is not a case of user error. My environment shows clear evidence of session token hijacking and automated configuration tampering. Specifically, my sessions are being forced into unauthorized linkages (e.g., Google OAuth backdoors) that I have explicitly revoked. Technical Evidence of Interference: 1 System-Level Artifacts: My browser instances (Safari/Firefox) have been rendered non-functional (failing to load pages) for an extended period, yet these applications continue to generate "browsing history" and metadata. This metadata is fraudulent—it is machine-generated output, not user-initiated activity. 2 Unauthorized OAuth Linkages: I have documented instances where 2FA-secured accounts were bypassed through the injection of secondary identity tokens (linking to an ainsleyhenn2024@gmail.com identity I did not authorize). 3 Malwarebytes Forensic Logs: I have attached logs from Malwarebytes, which provide objective, non-tampered evidence of blocked connections and attempted malicious interference that occurred simultaneously with the "bizarre" browser behavior I have witnessed. 4 Credential Bypassing: The behavior observed indicates a bypass of standard authentication flows. This suggests either a compromise of the authentication delivery service (the "Mail app" shell hijacking) or the deployment of a corrupted/compromised version of your software. Formal Request for Forensic Audit: The persistence of this activity suggests a systemic flaw or a compromised session pipeline. I request a Session Token Audit to identify:

The specific IP addresses and device fingerprints that initiated the unauthorized linkage of the Gmail identity to my account.
The OAuth scope granted during these automated handshakes.

Offer of Facilitation: I am documenting these issues in detail and have retained all relevant diagnostic logs. I am prepared to share these logs to facilitate a forensic examination, provided this inquiry is escalated to your Security or Data Integrity team. I am seeking a resolution that addresses the systemic failure to protect my data and ensures my account integrity is restored to a trusted state. Please advise on the secure channel for submitting this technical evidence for a full forensic review.

Due to unclear wording in the guide to your VPN, I'm a little at a loss for how it works.

So there's a 50 GB cap a month, but we can.... subscribe to get more? But I already had to subscribe to access the feature- I was literally given no other means of activation.

Do I have unlimited data now? Do I only have 50 GB? Do I need to pay for more data should I choose to opt for more?

Clarification for both myself and the guide would be greatly appreciated. Thanks!

what it says on the tin. went data purging with ol reliable WinDirStat and found this absolute behemoth of a file in the profiles directory for firefox. its especially weird considering the entire Firefox directory itself is only 1.5GB with this menace taking 1.3 of it. I cant imagine that bookmarks, search history, passwords, the works takes up any more than about 300mb. so im wondering if im just stuck in the early days of data or if the file really is just that girthy.
