Opening PDFs automatically with Firefox and, without any changes I might make, saving them with the download function in Firefox, actually ruins the functionality and data entry function of that file. Specifically this happens with PDF files downloaded from the (not all that amusing) PDFs from the FINCEN, (US Financial Crimes Enforcement Network). I do not see why and how Firefox thinks it is allowed to change files that are simply downloaded and saved on Firefox.

In other words, it seems that Firefox strips away certain "permissions" and/or "functions" (like built-in lookup, menu or choice boxes). This means that the file so downloaded via Firefox can no longer be used to properly fill in data, or to look up and choose data items within the file. (I see many times that ANYTHING having to do with "permissions" tends to be an intractable and unsolvable problem for software makers & experts, so, if you do not know right away how to solve the problem, it will probably take you several years to figure this out.)

The PDF in question is created by a government agency. If you have ever dealt with a government agency, then you know that they act sort of like Adobe or Microsoft: "They don't respond, or they do respond & say they do not understand, and if they understand, they are either unwilling or unable to fix the problem."

If there is a switch or option within Firefox, which lets me tell Firefox "Save this file exactly like it is received, nothing added or removed!", that would be nice. I just have not found such an option yet, and it would be nice if it might get provided someday.

I will share my browser data, but I am sort of convinced that a detailed question like mine will not be addressed within that shared data.

Since the most recent update ( or maybe a slightly earlier one,) I am unable to use macros on my Sidewinder X4 programmable keyboard. I can program a macro to a key but it does not work in Firefox. All other programs such as Word, Notepad etc. are fine. I am wondering if something in an update has broken it. It also works OK in Chrome

The regular version of the browser is open with a bunch of pinned tabs and a private version. And!!! If you close the REGULAR version , but DO NOT close the PRIVATE one before that, then when you try to reopen the REGULAR one, ALL OPEN WINDOWS AND TABS will BE DELETED!!! WHY?!?!

And these tabs are not saved in history, because they WERE NOT active in this session!

Where do developers' hands grow from?! Well, this glitch was a couple of years ago! But now?! A month of work preparation went to hell because of Firefox failure... How do I restore tabs that were just blown away by the browser?

Just updated Firefox desktop (Win 10 with ESU) to 140.10.0ESR and now every site I try to access gives

Secure Connection Failed An error occurred during a connection to www.google.com. PR_CONNECT_RESET_ERROR Error code: PR_CONNECT_RESET_ERROR The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the website owners to inform them of this problem.

Sites were all working fine literally right before. No other changes at all. Have restarted a few times. Have disabled antivirus and adblocker extensions. Same problem including at google.com and even firefox. Note on the About Mozilla Firefox window says " Failed to check for updates". Also cannot even use the links there to go to What's new or Firefox help etc. (Gives Secure Connection Failed error). No proxy server. Have tried turning anti virus completely off. Just a combined modem/router -- basically vanilla.

Firefox is my primary browser so this is extremely disruptive. I am using Edge to access sites and post this.. though curiously enough I noticed it gave some error when checking for updates. Do not want to do anything there or will lose complete access.

Any suggestions .. or how to go back to a previous version, if necessary. Need a workable connection to file taxes next week so this is important. Thank you.

I have no idea what is going on with Mozilla Firefox lately, but ever since the update to add the VPN has happened, (and I DO NOT use it), the response time for accessing any websites has gone into the toilet.

I use Venice AI for conversations. Venice AI says it stores my questions and its responses in my browser, not on their servers. I just refreshed my Firefox browser but forgot that Venice AI stores my conversations in my browser. Now my conversations are missing when I go to the Venice AI website. I have a folder on my desktop that is labeled "Old Firefox Data". Can I find my old Venice AI conversations there? If not there, where were they stored?

I'm using Firefox on Fedora 43 Linux, fully updated, and have it set up to use four desktops on the same monitor, using the Xfce DE and Compiz. For the last several months, any time I click in a link in Thunderbird, instead of switching to the desktop with Firefox on it, it pulls Firefox to Thunderbird's desktop and covers Thunderbird. This has continued through several updates of Firefox and at least one upgrade of Fedora. I don't know if Firefox or Xfce is the issue, but if it's Firefox, where do I look?

I can't open Firefox. I keep getting the message "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window.". I can't find it to close. I tried uninstalling it, but I keep circling back to the same message. I tried refreshing it and again same message. I un installled Surfshark VPN, I ran Windows Defender antivirus. I am now out of ideas. I do have two profiles, but the message about deleting them is scary. I don't want to do anything until I understand what I am doing.

Windows 11; all updates are installed, Dell computer purchased in October, with AMD processor.

Recently (about a month) I have found I often have to login to my Firefox account in order to access saved passwords etc. Sometimes from one day to the next. It never used to do this. Can't find any setting like "trust this device" or similar to stay logged in.

Hello, I am trying to customize the "Shortcuts" section on both Firefox for Android and Desktop homepage. I only want this section to display websites that I have explicitly pinned or added myself. However, if there are any empty slots left in the shortcut grid, Firefox automatically populates them with random websites from my browsing history. Is there a hidden setting (perhaps in about:config) or a native way to completely disable these auto-generated history shortcuts, so that only my manually added sites are shown? Thank you

Running Firefox in Kinoite - whenever I set a page to Reader view it is blank.

I have restarted in troubleshooting mode and it works, so I followed all the steps to try to identify what the problem is but nothing has worked.

I tried:

- Troubleshooting mode - worked - Disabling hardware acceleration - did not work - Disabled all extensions - did not work - Switched to default theme - did not work

Anyone any ideas?

TIA

bold text I contacted Directv.com via chat. After trying to sign in to my account on Firefox (which was successful), I could not go to either MY ACCOUNT INFO. or any other page without being signed out AUTOMATICALLY upon clicking any further tab (such as MY TV Package). Their chat technician said that FIREFOX is no longer supported! Is there any way to fix this?
