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.

On Firefox(Archlinux) i can't change website fonts. "firefox-151.0.4.tar.xz" https://download.mozilla.org/?product=firefox-latest-ssl&os=linux... can't either. Even though FF-snap and FF-flatpak can. How can i fix ?

On my new dell laptop, Firefox seems to run well. however, when I select one of my regular bookmarks from the dropdown, it ignores the choice and chooses a link (e.g. a news story) from the page I'm currently on, one directly under the bookmark I've chosen. If I choose the bookmark link again it operates correctly.

Dear Mozilla Firefox:

Re: Very Transient Search Specifications

Having disabled AI search capabilities satisfactorily, I am now plagued with re-establishing search specifications innumerable times a session. I open a tab. I set my safe search requirements followed by several items under “All Search Settings,” then save and Exit. I open a new tab and repeat all the steps. I back up out of that search list, not backing up past the window with the saved settings to find they are nevertheless reset back to default, necessitating that I repeat all the steps. I leave this window of Firefox open but minimized and open a new Firefox window and repeat all the steps.

Of what use is saving the settings? They don’t persist within tabs, across tabs, or across windows. These inconveniences began with the introduction of AI services to Firefox. Yes, I delete cookies and set other parameters in the name of privacy, but not with the expectation that saving search settings during a session will prove meaningless. Please let me know and understand how to have both privacy and utility.

A long time Firefox user and supporter.

Today after i restarted my laptop (windows) and then I started firefox all the pinned and also the normal tabs were gone. I tried to follow different indications about restoring the previous session, but nothing showed up. All the tabs are gone.

As I need these tabs and this is obviously an issue of the software, PLEASE FIX THIS ASAP.

Is not possible that this happens every 1-2 months.

Hello, I am hoping someone can help me. I am getting white pixels/lines during youtube play back. There is only ever one at a time. I do not get it every time I watch a video. The lines move with the player if I move the browser.

I have tried: Updating Firefox/drivers Turning Hardware acceleration on/off Setting Firefox to use the dGPU Changing the Optimus mode

I am using Windows 11 and have a Legion 7i Pro Gen 8

I have uploaded an image that shows the line. The line appears in the grass on the right.

Many thanks

If I upload a jpg image via the + in the Gemini prompt it fails with an ! or doesn't give the (up pointing arrow) execute option prompt. Do usual things and even clean installed Firefox. Same on 3 windows 11 PCs 2 of which not my own hence not configured the same. All did work until latest updates. No browser extensions antivirus temporarily turned off. Same in, private and safe mode. All work fine on Chrome or Edge (sorry to swear at you) A work around is to load them via Google Drive or Photo and pull them from Google platform.

i really need this colour switch pls. my firefox kept crashing with no explanation (maybe some extension i had, then deleted when the crashes began) so i had to reset the whole thing. now the appearance has changed. i had put back my background picture, witch was fine with me, but the text was black instead of white like it used to. and it makes me use firefox less. i think its something to do with the website contrast but I'm not sure.

I received a pop-up scan code to get Firefox on my phone, but when i scan or take

photo of it it brings me to an on-line survey panel that I am a member of.Is that legit or something to avoid?

Hello, I noticed a few times that after waking my computer up from sleep mode, I seem to lose audio from the browser completely. I look into my audio mixer and I do see the browser is giving audio, but I can't hear it through my headphones.

Last time i fixed it, I had to restart my computer and it fixed the issue, but I don't want to continue in having this issue at times. I have also tried restarting firefox by ending it in the task manager and re-opening it, but that doesn't seem to fix it.

I have an insta 360 webcam with Virtual Camera enabled. Is there a setting for Firefox where I can select from a list of available webcams (cameras)? I am suspecting it is trying to use either the integrated laptop camera or the Insta360 without using the Virtual software.

Thanks in advance for your help

The "Post" button is off screen on the share popup when I try to share a post in a Facebook group to another group. The problem has been getting worse. Usually I can see a slim piece of the top of the button, but today it disappeared completely. The only way to make it visible is to press Ctrl -. Then select Zoom > Actual size from the menu when I'm finished.

Hi,

Can we get an auto-reconnect feature in Mozilla VPN?

It's a requirement for my particular setup as my agent operates independently, but errors out when the VPN is off. Ideally we would be able to select the suitable regions that it tries to connect to after a drop - a first, second, third drop down menu or similar would work.
