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.

The Widevine Content Decryption Module failed on both our Windows 7 PCs. Version: 4.10.2891.0 Last updated Apr 2, 2025 when our version of Firefox was updated. The current version is 115.22.0 est (64-bit) (Streaming is OK on my Mac using Safari and Chrome; don't have Firefox installed there)

Over recent months, there have been quite a few reports of this issue on several operating systems. Our viewing of videos only failed us on April 2nd or 3rd, 2025, not previously. This seems to be occurring at various times in various systems. Solutions are not accessible to lay folks, and Google is inaccessible! Can anyone help us? Thanks

Hello! I'm trying to download a quantity of audio files from a specific website. Once I open firefox, I can manage to download a few in that session - anywhere from 1 to 10 usually. Then, at some point, the downloads start to hang. They appear as how they do when they're loading - "Unknown time left - 0 bytes (0 bytes/sec)". However, they never load. The only solution is to restart Firefox, to be able to download a few more.

I'm on Linux mint, Firefox version 137.0.2 (64-bit). I tried running firefox through the terminal to see if anything would show up when the downloads stop working, and I got this:

[GFX1-]: RenderCompositorSWGL failed mapping default framebuffer, no dt [Child 47831, Main Thread] WARNING: Unable to open /var/lib/flatpak/exports/share/dconf/profile/user: Permission denied: 'glib warning', file /builds/worker/checkouts/gecko/toolkit/xre/nsSigHandlers.cpp:201

And a lot of "ATTENTION: default value of option mesa_glthread overridden by environment." - but those seem to happen all the time during regular usage.

Any way I can go about troubleshooting this, or am I stuck with restarting Firefox every few files I need to download? Thank you in advance for any help or advice.

When I have firefox open for a while, not sure how long, the display starts to mess up on some pages. When I print those pages, the words are still messed up. One place is printing things form the Virginia Department of Taxation I-File. I do not like to close out of the browser every single day and with other browsers I do not have to. This is new and started this year. Not sure when. How do I fix this issue without having to restart the browser and close out of everything all the time?

More recently, for the past few months maybe, I sometimes get a white menubar when Firefox is in the forefront. Clicking on it will restore the menubar.

Here's a pic

I am using the latest Mac OS, 15.4.1, and it happened with the previous version too.

Thanks for any help.

I am trying to run Firefox on a MacBook Air from 2015 (MacOS Monterey 12.7.6) and it has not worked since I updated Firefox a few days ago. I have tried deleting it and downloading it again - same problem. Can not pull up any website. Eventually I get a dialog box "Firefox Crash Reporter".

Firefox uses too much memory, with 1 tab 1GB+, and with 4 tabs all 3GB+, this is not normal, the forum topic did not help, reinstalled and did not help, there are no more than 6 extensions, and they consume only 160mb.

i've recently had problems with not being able to login to certain accounts (others are fine) resulting in hanging. other times i might be writing a message (or other) and the browser crashes. can you help me, please?

Hello,

Since the new version of Firefox desktop 137.0.2 my xslt is no longer interpreted correctly. I use the xpath-function document to load external xml documents in my stylesheet. But no document is since the new version loaded. Also with links to intern pdf-documents I receive the error "file not found".

I saw that in the new version there was changes in xslt. Is my problem a bug or may be exists there a workaround (in changing settings)?

Thanks a lot for your answer. Regards, Tomateus

Sometimes when watching a video on hulu (and maybe other similar sites) after a commercial the screen is all messed up and I have to stop the video and reload to get a picture. The sound is fine but the picture is messed up. This only happens with firefox. Any ideas on how to fix this?

Roboform doesn't show up in the toolbar and it doesn't pop up to suggest passwords. Video download helper doesn't show up in toolbar. This all started after the latest update. Thanks Bob

Could not get email via the usual Firefox. Always have used Firefox to get it. What happened ???

Then something called Moxilla came along. What's that? Why do I have to use Moxilla? I want Firefox. How is it related to Moxilla? Why did something change without my permission?

Thanks, Deanna Rose
