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.

Ich habe über die Sicherheitssoftware "Trend Micro Security" eingestellt, dass keine heiklen Daten wie Kreditkartennummer, Debitnummer, Kontonummer etc den PC verlassen, ohne dass ich zustimme. Nun bekomme ich, wenn ich Mozilla Firefox öffne, ständig die Warnung von Trend Micro, dass die Sicherheitssoftware verhindert hat, das Mozilla eine von den gepeicherten Nummern übertragen wollte. "Die Funktion zum Schutz vor Datendiebstählen hat verhindert, dass geschütze Daten den Computer verlassen." Angegeben ist das Programm "Firefox.exe". Was passiert da bei Firefox im Hintergrund?

Hi All:

I just got a new laptop and so I am getting everything set up the way that I like it. I have come across a problem with my sidebar though. I like to keep my bookmarks up all the time, but I want them to not be too wide and take up a lot of my screen. On this new computer, there's an addition 5 cms or so of white space at the far left of the tool bar. It had different buttons on it up at the top (one of them had something to do with AI) and a little gear down at the bottom of the space. I was able to remove all of the buttons up at the top, but I can't seem to hide the whole thing. I just want to see my bookmarks, without that extra customization sidebar. Is there a way to hide the spot highlighted in pink, but still have the bookmarks visible?

I manually added shortcuts to my home screen, but everytime I open the browser, the system automatically has added shortcuts I don't want. Also, when I delete these unwanted shortcuts, another unwanted one appears.

how can I stop this from happening?

I would like to setup Firefox so it checks for updates and installs them during maintenance windows (overnight) and runs the updates as 'system' account. This is how Chrome and Edge handle updates.

I tried using the following GPO settings

Application Autoupdate Enabled Background updater Enabled Disable Firefox Studies Enabled Disable Telemetry Enabled Disable Update Disabled Don't Check Default Browser Enabled

This seems to create Schedule tasks in Windows task scheduler, but the tasks are running as previously logged on user accounts. which doesn't help us in this particular environment.

I know we can manually push out the latest version via creating new MCM application pushes but the amount of updates that are coming down is a labor intensive exercise and we don't have the budget for PatchMyPC

Please post any thoughts!

It has been two times now where I will open firefox and suddenly all my profiles are gone. I have tried everything to try to get them back like trying to get "old firefox data" back or about:profiles, but there is literally nothing to recover. All of my bookmarks and passwords are fine but I have to log in to everything all over again and reset my home page with all my shortcuts. it is extremely annoying, especially when I use up all the shortcut spaces. It prompts me when I start firefox to create a profile, sign in again, and set firefox as my preferred browser. I have been using firefox for about a year and havent had this problem until a couple of weeks ago. What can i do to avoid having to do this again in the future?

Places where I've observed this behaviour:

• The 4th video in the description of https://store.steampowered.com/app/1363080/Manor_Lords/ (ignore the media carousel at the top of the page)
• This video https://dolphin-emu.org/m/user/blog/progress-report/2603/rebelstrike-texturestreaming-av1.webm that's loaded in an embed at https://dolphin-emu.org/blog/2026/03/12/dolphin-progress-report-release-2603/

When these videos are in view and playing, they're decoded using the CPU and the browsers frame rate tanks (heavy/laggy scrolling when scrolling with mouse scroll wheel), I have a Geforce 3070 which includes support for AV1 decoding so I'm not sure what's happening.

AV1 videos found on Youtube like https://www.youtube.com/watch?v=foqVJq-XPTg are fully hardware accelerated by the GPU (Stats for nerds confirms it's playing an AV1 copy) and doesn't exhibit any performance issue.

GPU usage is monitored by Task Manager in Windows 10. For the problematic videos the GPU Decoding is at 0% with a workload being spread across many of the CPU cores. For the non-problematic 4K video the GPU Decoding is around 60-70% and no workload is distributed across multiple CPU cores.

Hi Team,

Since yesterday I am observing the issue while accessing Whatsapp which is asking for Quick security check with passkey and same was observed in Google which was resolved within few clicks but not Morzilla.

Currently using with Google.

i get confused about which firefox i am using when i click the fox.is it mjcrosoft or or the app i downloaded from the web. can one be deled without messing up the other FFox account  ?

I lost my bookmarks and toolbar and cannot save any new bookmarks. I found the backup for the bookmarks but I am unable to restore. I also cannot find my profile file either. What can I do?

Downloaded recent Firefox update. Restarted PC. Logged into a site I use (and need this season). I could not even use a saved bookmark for login page. Cannot log in to it.

I added the site under Firefox settings option.

I tried logging in with Private mode, where I was able to use bookmark for login page. HOWEVER, I quickly experienced issues and got attached warnings. I reported 'site not working' on the debug option. While this usually immediately fixes a problem, it did nothing at all.

This is why I am always AFRAID of installing the "Updates" - I frequently lose functions. It takes as TREMENDOUS amount of time to fix them and there is no "help button" on Firefox or Mozilla to scan issue and fix it.

I posted this in the Android section a couple of days ago, but since I've had no responses I thought I should try it here in the hope it'll catch someone's eye. Hope that's acceptable.

Here's my question:

Can I fine-tune sync the way I want?

I would love to be able to sync bookmarks and passwords between two desktops yet sync just the bookmarks to a third device: an Android phone. Why? Because while I want my bookmarks available everywhere, I don't want sensitive passwords on a device that leaves home.

But I don't see a way to do that. I've tried, and I find the passwords end up being synced no matter how I configure the settings.

Nor, apparently, can I export the bookmarks and passwords to a file, strip out the passwords, and import the bookmarks alone to the phone--what I was hoping could be a workaround. I gather one can't import to mobile Firefox. Have to sync.

So I'm back where I started: unable to do what I want to do.

And I missing something? Post a Reply

Hi Had some problems with the computer. According to Microsoft the dll error was caused by the new Adobe acrobat. Trying to fix this problem some of the websites in Firefox are having now problems. EXP. Kohl's Error code: SEC_ERROR_REVOKED_CERTIFICATE. Home Depot Oops!! Something went wrong. Please refresh page. This is only happening in Firefox with Windows 7, Firefox version 115.33.Oesr 64 bit. When I access these two websites on Chrome in the same computer everything is fine.

What is causing these errors in Firefox????? Can you please help!!!!!
