Firefox Community Forum

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.

I just bought a new laptop with Windows 11 and installed Firefox onto drive C: of the 1 TB SSD. I then decided to partition the SSD into three drives and put Firefox on the E: drive. After I partitioned the SSD and uninstalled Firefox, I downloaded the Firefox installer from Mozilla, and ran it, but it somehow perceives that I had had Firefox previously installed and only gives me the option of re-installing Firefox at the original (C:) drive location. There is no longer an option in the installer to change the installation location. How can I get around this and re-install Firefox on my E: drive instead of my C: drive?

Did Not Connect: Potential Security Issue

Below mentioned issue occuring ???

Firefox detected an issue and did not continue to finance.jharkhand.gov.in. The website is either misconfigured or your computer clock is set to the wrong time.

It’s likely the website’s certificate is expired, which prevents Firefox from connecting securely.

What can you do about it?

finance.jharkhand.gov.in has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

Laptop Windows 10. Firefox/Mozilla ask me to update. Did that 3 hours ago. Cannot find my History and Bookmarks from prior update. I have restarted my laptop since but still nothing... Can you please help?

Newly installed FF browser. Tried transferring bookmarks from Chrome to FF using "import bookmarks" menu. Appended .csv file without error but still bookmarks cannot be seen. Tried method two. Using Chrome bookmark manager, downloaded .html file. Used FF again to append without error but the same no bookmarks seen.

Is it really impossible to automatically transfer bookmarks from Chrome to FF?

There’s no information on how to sign out of the AI bot itself. For example, if you use Copilot and sign in, then realize you used the wrong Copilot account, there’s no clear way to sign out and log in with a different account.

I am in the process of switching from Windows 10 to Linux Mint (Cinnamon 22.3) as my daily operating system. My current Windows version of Firefox is 147.0.2, for Linux it is 147.0.3. installed from the official repository - also known as the Software Manager in Linux Mint. I've configured Firefox exactly the same in both operating systems. Running under Windows when saving a Bookmark, Firefox displays the well known Globe Icon, but after reloading the page the Favicon appears immediately (provided it is available of course). Under Linux Mint this does not happen, even if one restarts Firefox. Only after a system reboot Favicons of revisited pages become visible. Is this a fundamental difference between the Windows and Linux version of Firefox or am I missing something? I've installed the Firefox extension for caching the favicon, but it made no difference, If I run it, still the Icon does not appear until system reboot. I couldn´t find an answer in the help database nor on the Internet in general.

This difference might seem insignificant for most people but for me it is. When shopping on the internet I bookmark a lot of pages of products to be able to make quick comparisons. The Favicon is of great help because it makes it easy to identify the different shops. Of course I could manually change the bookmark name to include the shop name, but Icons are a much better clue and leave more room in the bookmark name for other information.

Reinder

i am trying to type this message on firefox, but i have to avoid shift key not to interrupt typing. when i hot shift+some other keys like i, b, v, etc, devtools pop up. i have checked other forums, other q&a on firefox support, and concluded that the same issue have occurred to many users regardless of the os, features, extensions, various keyboards (but not the virtual one for me) or system settings. i have to type a lot in the browser, so i just choose to delete firefox until someday the issue is fixed.

I am using version 147.0.1 (don't know when last update) For the last 1.5 hrs I have been trying to restore the extensions icons as well as other, to the tool bar. when I close "customize" after putting them there they disappear, as does the "puzzle" piece I put up there. What is going on? I have read numerous articles on how to fix this to no avail. Only one character will stay to the right of the added search bar.

i had a bunch of grouped tabs which i 'closed and saved' but when i tried to find them all of them were gone, only the newer groups i made just now show up, not a single one of my old ones do

Hi Team,

after the mentioned update about a week ago, I experience quite some system slowness. Building up new pages takes between 30 and 60 seconds each, and some live streams are interrupted (3 seconds running, 3 seconds stop, 3 seconds running, etc.). This has never happened before. My Internet connection is good (confirmed by the provider), and using Google Chrome, all is as it should be, no slowness, no disruptions.

Can anybody advise, what the cause(s) could be, and how to solve these issues? Please let me know, if you need more information.

I really would like to continue using Firefox.

Many thanks in advance for your assistance,

Michael from Norway

I have been running version 147.0.2 on Windows 10 Pro. I manually downloaded the version 147.0.3 updater and ran it without any apparent problem. However, when doing the required restart, the update process did not complete. Multiple restarts and cold boots have not remedied this. When I start Firefox using my desktop icon, version 147.0.2 is started.

My "Programs and Features" window shows both versions are installed. When trying to uninstall either version, in either order, I receive a message saying that the system should be restarted to complete the update process. As stated, this does not work.

Following a restart, the Performance Monitor does not show any recognizable "ghost" processes that would need to be stopped.

Inspection of the System event log showed the following Warning:

 *  Name resolution for the name push.services.mozilla.com timed out after none of the configured DNS servers responded.

There may be other warnings / errors that are pertinent to this situation, but that was the only one that mentioned "mozilla" or "firefox" by name.

Since Version 145.0.2, November 26, 2025, 1. firefox won't print anything anymore. No matter the way that I select something to print (print to PDF, print to printer), firefox won't print anything anymore. The print options screen does pop-up when "print" is selected , but when "print" is selected on the print screen pop-up nothing happens. This includes the "print to PDF" function as no "save to" file folder pop-up opens to select where you want to save the pdf file to. After an update prior to the "Version 145.0.2, November 26, 2025" firefox no longer allows you to move your tabs from their original positions to the left or right along the tab bar in the browser. I use to be able to click on & select one or more tabs and move those tabs anywhere to the left or right of their original position to anyplace along the tabs bar. NOW at present, the only way to move any tab's position is by "right clicking" on the tab, select from the drop down "move tab" and selecting 1 of the 3 options ("Move to start", "move to end", & "move to new window"). You can also add tabs to groups through the "right clicking" process. Unfortunately you can't simply move tabs in any other ways without using those "right click menu options. This is VERY frustrating because I constantly move tabs (or strings of tabs) to better group them without having to add them to specific "groups". And speaking of groups, you can no longer rearrange the tabs in "groups" either.

These are both some of the most basic and general functions for firefox that no longer work in firefox 64 bit on windows 10 OS (my primary PC, but the same holds true on Windows 11). You should also note that recent updates also occured on both Windows 10 & Windows 11. I am still currently able to print from and move tabs in the Edge browser which I have had to start using more & more since these functions stopped working in the firefox browser. I've always preferred using firefox even though it is a huge resource hog, but if firefox doesn't fix these problems soon. I will have to resort to using the Edge browser over using the firefox browser. That reminds me of a 3rd problem with your "unload tab" function, 3. The "unload tab" function ONLY works if you click on and open the single tab first. The "unload tab" function ONLY WORKS for a SINGLE TAB at a time. When/if you select multiple tabs and select the "unload tab" function in the "right click" drop-down, ONLY the first tab selected and that you are currently on, using, and viewing will "unload" while NONE OF the remaining selected tabs will "unload". You need to make a way to "unload" ALL TABS that you are NOT currently viewing/using as "unloading" tabs one at a time is painfully tedious. The "unload tab" function would be a great idea to reduce firefox from being the huge memory hogger that it is, but only if you make using the "unload tab" function's use less tedious. Perhaps Mozilla should consider making the "unload tab" function less necessary, by either making the "unload tab" function automatic and not NEED to run every opened tab until said tabs are actually in use & actively being used OR BY making firefox less of the enormous resource hog that it has become.

I have used Firefox since its beginning. Now I can't access many websites. These include charities, financial institutions, and more. Sites just spin and don't load. I couldn't even print my puzzle tonight. I have no idea why I now have to open other browsers to get anything done.
