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.

Hello. I am setting up a site on Linux server using Apache as reverse proxy , with ASP.NET as application server . since installing SSL , I had few mixed content blocking that i was managed to fix using CSP directive in Apache configuration file. site has no issue with all browser except Firefox. the only issue is that in admin section , to configure a option. system will load a js file that simply a dropdown with list of options to choose from . when using Firefox , it tries to redirect that page to login page . for test , i clicked on the link i located in Developer tools , which directed me to login page , entered my credentials, and scripts loads showing the drop down box and ok button. is been 3 weeks i been looking for every solution and i have done everything .. but nothing have worked. now I am resort to having to use other browsers if i need to use that functionality in admin page. In page header file name : login , location : http://MYDOMAIN.ca/login?ReturnUrl=%2FAdmin%2FDiscountRulesCustomerRoles%2FConfigure%3FdiscountId%3D6%26_%3D1702682353293 , which are not correct . and browser such as Brave and Safari dose not show different path and file name and everything is correct. dose anyone know how to fix this .. ? i saw a solution mentioned as stated resting Firefox ,but can not find a way to reset , but i have reinstalled Firefox and constantly having this issue on this single section of the page . Thanks.

For about the past 24 hours when I go to youtube to check out a video - nothing works? I clicked on a video to play, got the sound and no picture. I closed out my browser and I kept getting the audio of the video and had to shut down my computer to stop it. Now when I go to a video nothing works. My cursor disappears when I go to chick on the video and I have to move it off to the side just to see my cursor.

I also use a service (VidIQ) that helps me see the tags on the right hand side of my screen for a video and the channel so that I can compare those tags to my videos that I am uploading.   Now that never load just a spinning dial or object like it is stuck.

I hope that you can get this fixed soon or let me know if there is something that I must do at my end.

Thank you,

At home we have a shared computer with Ubuntu and Firefox as main browser. Each family member has its own Linux user.

We use the functionality of Firefox saving passwords, however we've noticed that these passwords are visible between the Linux users. So, for instance if two of us use the same website, somehow our user/pass get are visible to each other. Is this behavior expected? How can we set FF to make the user/pass visible only to the Linux user who is using it?

Cheers

Hi,

Firefox version: 139.0.4 (64-bit) OS: Windows 11

I have been having issues where Firefox tab will just crash out for no reason it appears and it happens at random times and once the tab start to crash, and I restore it, it will crash again and again. The only way tog et out of the loop is to restart Firefox.

I have tried: Refreshing/Reset, Clearing Cache and History removing all themes, disabling extensions, disabling my anti virus. Turning off hardware acceleration didn't make any different.

I currently have 2 extensions enabled: uBlock Origin 1.64.0 and Bitwarden Password Manager 2025.5.0

In the about:Crashes I have reported them all and they seem to have the same type of reasons in the Raw data/Minidump which are: EXCEPTION_ACCESS_VIOLATION_WRITE EXCEPTION_ACCESS_VIOLATION_READ

Any help as to what to try next?

Recently I've noted that tabs on my browser move from where I had them all the way to the far right end of the tabs list, and it happens at random. There'll be times when I click on another tab while listening to music or a video on another only to find the tab I was listening to had moved when I go to click back on it. Without fail, I've found these tabs at the far right end of the set of tabs, and I need to know how to put a stop to this. It's inconvenient, and annoying in extreme. This has to be due to a recent update, because up til a couple months ago, this didn't happen at all. If there's a setting that I can change in about:config, I would like to know about it, because you can bet I'll disable this feature.

updated my wife's computer firefox to 115.24.0 (esr) and the profile data is lost (bookmarks, addons...).

Went to about:profile and it says PROFILE IN USE: default esr which is the 5th out of six profiles, top to bottom. It should tell me the creation date for each profile.

The 6th in line says "profile: default -release" Is the last in line the NEWEST profile? Should I set that one to be active ( ie the "default profile)?

This usage of the word DEFAULT in multiple meanings is confusing The display should number each profile and tell the user which is the oldest to newest.

This is acting like it is a new version, not a mere update - the user should be warned before he is allowed to perform that process, and given links to what will need to be done to retrieve the previous Profile.
