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.

Hi!

I am getting messages that I am blocking ads for many of my internet requests. I had never received these before but all of a sudden I started to get them. I have tried a number of things but nothing works.

I am running Windows 11 and do not have any Ad blockers.

Firefox spotted a potentially serious security issue with hrms.devrising.in. Someone pretending to be the site could try to steal things like credit card info, passwords, or emails. Advanced What makes the site look dangerous?

The site is set up to allow only secure connections, but there’s a problem with the site’s certificate. It’s possible that a bad actor is trying to impersonate the site. Sites use certificates issued by a certificate authority to prove they’re really who they say they are. Firefox doesn’t trust this site because its certificate isn’t valid for hrms.devrising.in. The certificate is only valid for: isp.afd2.jiohs.net, signup.jiohs.net, frontend.afd2.jiohs.net, www.frontend.afd2.jiohs.net, acc.afd2.jiohs.net, blk.jiohs.net.

Firefox browsers are not working on the Office 365 web portal. None of the links in the site work. The apps link for Office apps is missing. We have tried it from multiple computers and used both Firefox and Waterfox. The Office portal loads but is stuck on Web more and clicking on the Work tab at the top does nothing. Clicking on anything else on the page also does nothing. The same portal page works normally in Edge and Chrome.

Issue: When Firefox starts after a system reboot, it starts on the incorrect desktop. This seems to be off by one; that is, I have Firefox assigned to Desktop 3 (using the Dock icon's Options menu). Under normal operation, it starts on Desktop 3, but after a reboot, it seems to start on (more recently) Desktop 2 or (earlier) Desktop 4. Unsure about what causes it to prefer 2 vs. 4.

This seems to happen after I've shut down (quit Firefox normally, shut down without reopening windows on login, power goes off, power on, log in, then click on the Firefox icon in the Dock) or after a system update (which reopens windows on login for me after rebooting and installing the update). It does not seem to happen after a Firefox update or after quitting Firefox normally and then restarting it from the Dock icon right away.

Pretty irritating, as I have major applications assigned to specific desktops, and Firefox is the only one that seems to forget which desktop it should be on.

Details:

Firefox 150.0.3 (aarch64):

• Settings > General > Startup > Open previous windows and tabs > TRUE (checked)

macos 26.5 (25F71) Tahoe:

• Settings > Desktop and Dock > Mission Control:
• ---> Automatically rearrange Spaces based on most recent use: FALSE
• ---> ...switch to a Space with open windows for that application: TRUE
• ---> Group windows by application: TRUE
• ---> Displays have separate Spaces: TRUE
• Dock > Firefox application icon > [Right Click] > Options > Assign To > This Desktop (i.e., Desktop 3)
• Apple Menu > Shutdown > Reopen windows when logging in: FALSE

MacBook Air M4 2025 24 GB RAM:

• No external displays connected

the web page will show a currently typing cursor, the little blinking line on typing stuff, if i misclick lets say on an amazon product page it will just appear. its like the code has changed to make every screen/tab/window/page a word document and i dont know how it happened, how to fix it and what all it even is so help would be massively appreciated, thank you. sorry about the typing and commas thigny idk what is called in english as english is no my first langwige

I normally have 4 windows open, each with multiple tabs, for 4 work streams.

Whenever Firefox or MS decides to do an update, one window sometimes, 4 rarely, none usually, are recovered after restart. How can I ensure that Firefox remembers all the windows and their tabs before shutting down? Then reinstates them after starting up. After the last MS update, the option "Recently closed windows" was greyed out. But there had been 4 of them.

Firefox's recovery after simply rebooting the computer is more, but not completely, reliable. Win11 on a desktop computer

Thank you

Since updating to the new Firefox 150.0 (aarch64) - two of our client's websites are having issues with too big/distorted logos (png files).

Sites are A-OK in Sarfari and Chrome.

solarisiaq.com

Remade the images and re-uploaded (thinking the files were corrupt). Did not fix the situation. Cleared every cache available (object, builder, browser, hosting).

Could there be an issues with the browser?

I cannot listen music from browser through bluetooh attached device. I ave a bluetooth speaker which I use for all apps on my laptop. Today I noticed that it does not send signal to the BT speaker but through the laptop speakers. What can I do or what settings should I change. Laptop and BT speaker are paired. Thank you!

Running into more sites rejecting FF as my browser. Latest as of 4/14/26 : https://carespaceportal.com/chart Had to click to ignore notice to switch to Chrome. Site seems to function w/ FF 149 so far when i log in. I used MS BING search points to extend my Win 10 edition Desktop computer 1 year... There was no mention about my MS Win 10 edition. I'm logged in,,Not sure why this FF page "unable to pull your browser’s troubleshooting data"....

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.

I'm using a Mac Mini M2 Pro with Tahoe 26.5. I have two printers, the Samsung laser printer is listed twice but only the fax printer of my Epson ET4850 is listed. I can't find a way either to adda missing printer, or to edit the list. I've reset the printer settings using about:support to no avail.

I can not sign into a banking site - last several months. It gives me this feed back : "Explanation The Application Gateway attempted to fetch the resource you requested from a junction Web server. However, the Application Gateway received an authentication challenge from the junction server while handling your request. There is currently no sign-on information configured for this junction server. Solutions Configure the junction with the appropriate sign-on information. Disable authentication at the junction Web server. " How do I do this? I try to keep FireFox up to date . On Mac Tahoe 26.3.1

Good Afternoon. After updating my W11 machine with the latest Firefox version 150.00 programs inside online OFFICE do not open! I have tested with Chrome and it is working fine. Please verify this issue. many thanks
