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.

High contrast setting only support 2 colors(unvisited links and visited links) as a consequence it does not support radio buttons(switches that move to left and right to turn on features). the buttons are invisible and waste hours of the users time.

Upgrading from System 7 PC to windows 11 PC. On new computer (windows 11) downloaded firefox, logged in; Bookmarks transfered, but some sites (AOL.com, for example) auto filling very old password. Old computer auto fills correct password. On new computer, password manager shows correct password. Why is it not working?

So, I've just went on a quest to find a solution to my pinned tabs disappearing every few days, and it seems like this can happen if I don't shut down Firefox properly. Is there a way to stop this from happening?

That's my question. The rest of this is curiosity about the issue since it's seemed to have persist for a few years:

Is this intended behavior? No other browser I use does this and judging from the hits I got here, and elsewhere, it seems undesired. Is there some security or privacy reason it's like this?

I know I can repin the tab, or take some session recovery steps, and a few other things... but IMO, those are workarounds, not solutions. Barring some technical or mission limitation, a true solution should prevent this from happening at all.

Dear Mozilla Firefox Support Team,

I have been a loyal Firefox user for many years because I have always appreciated its speed, privacy, and reliability. However, I have noticed that Firefox has become slower over time, and I am disappointed with its current performance.

The browser feels increasingly sluggish during everyday use. One of the biggest issues I experience is with YouTube, where videos often do not play as smoothly as they should. I also notice that Firefox consumes a significant amount of RAM, even when only a few tabs are open, which affects the overall performance of my computer.

I sincerely hope the Firefox team will prioritize performance optimization in upcoming updates. Many users, including me, want a browser that is fast, lightweight, responsive, and efficient with system resources. Speed and smooth performance are some of the main reasons people choose a browser, and I would love to see Firefox become the quickest browser again.

Please continue improving memory management, reduce unnecessary resource usage, and optimize YouTube and other modern websites for a smoother browsing experience.

Thank you for your hard work and for listening to user feedback. I hope future releases will focus on making Firefox faster, lighter, and more responsive.

I am on Firefox 152.0 (64-bit).

When I view a pdf in Firefox it looks centered like a normal page.

When I send it to print from there, it left justify the pages. I have tried changing the Scale, Margins. The paper size is Letter 8.5" x 11". I have 2 different Canon printers (laserjet and inkjet) and no difference.

If I download it and open it with Microsoft Edge and send it to print, it prints centered like a normal page.

I have tried to search articles on this topic. They were all very old. Some says to make changes in about:config in the address line. I tried a couple. Yet no difference.

Hope you can help.

Firefox 152.0, latest Windows 11 25H2 update on HP TP01-1036. I have tried just about all the AI fix suggestions but nothing works to fix the following problem:

When viewing the Yahoo.com News page, I scroll vertically down to see each article...one after the other. When I come to an article I want to read, I left click it. The article opens within the present tab and is closed by clicking the red "X " at the upper right hand corner of the article; which in turn, returns me to were I was before opening the article. However, eventually, after a few articles are read, when closing an article, the cursor will jump back to the page's first article instead of bringing me back to where I left off on vertical arrangement of the news articles'? This has been happening for around the last one to two weeks. Nothing else seems to be out of wack.

Недавно сбросил телефон до завода, но перед этим зашел на вк аккаунт с купленным номером и фейк данными к которому привязанно достаточно аккаунтов от почты... А проблема в том, что как оказалось делал я это через приватный браузер! Ну окно случайно закрыл и по итогу потерял все что перенес( Служба поддержки в вк ни чем помочь не может , тк привязан номер не мой (а его я вообще не помню) + данные (ФИО) левые. На почту я также не могу зайти , тк они привязанны к вк айди и подтвердить что вк мой - не могу пхахах

i have been using the old yahoo for years and now it seems they changed the layout to resemble google. it sucks. if i wanted googles layout i would use my google email. if i use this term https://mail.yahoo.com/d/settings/1 i get the old yahoo setup screen and then i have to click return to mail and the old screen stays until i either restart the pc or restart fire fox. i do not see in fire fox setting an area that lets me put in a startup term like chrome has that will restart yahoo in the view i like. being that view is still there.

the old view that i like with the blue on both sides

                                                                                  the new view with the email control tabs to the left and not all show is the right shreen shot or bottom screen shot

During the last 2 weeks, I have been unable to view and use my AOL emails, for the login page demands that I enter my mozilla primary password--the existence of which was unknown to me and thus, I never knew what it was and never had to use it in any way. I assume one was set when I began tom use firefox probably back in 2016. My big problem is that I must be able to use my AOL email system to complete various essential needs, How can I fix this idiocy that apparently places some kind of security above sane simplicity and ease of use for normal people who are not computer or Internet experts?

While Using Youtube : from the starting page (that comes up with multiple Clips displayed), I attempt to do the following: By selecting Open Link in a new tab, or Open Link in Split View (So I can Watch a specific clip without loosing the original displayed clips on the starting "face Page") ...the selected Opened Link Immediately Becomes Greyed Out And Refuses to Play the the Clip. To watch that clip I must close the video clip that I selected to then return to the original opening page to then Move the pointer back over the smaller box-clip that I want to watch, leaving the pointer on that clip is the only way to watch the clip. This Just Started Happening Recently...... This is Happening Every time..... Apparently, if you want to watch ANY of the displayed clips from a Start "Face Page" you can Only watch by hovering the mouse pointer on that specific Small Box Clip on the starting page...I can't bookmark that page without selecting the page to another Face Page, which then looses the smaller multiple clips on the original face page that I started on.

Hello,

When I opened Firefox this morning, it downed the newest version.

Since then it becomes nearly impossible to use, locking up after a few minutes.

Are you aware? Is this being fixed? Can I go back one version? I used Windows 10, is that the issue?

Thank you.

power up and get previous home page with bookmarks page from prior session. cannot delete page using 'x' upper right. cursor not effective . I have to click on firefox logo to start a new session. Note the old display comes up at each login. Cannot delete I must overlay. Please help. Greg

Hello,

I'am testing a GPO to deploy the Lockself extension on windows 11 for Firefox 152, the JSON used in the GPO setting is the following :

{"{ca613ee6-4211-4ae2-aa3c-d29608461d11}":{"installation_mode":"force_installed","install_url":"https://addons.mozilla.org/firefox/downloads/latest/lockself-password-manager/latest.xpi","updates_disabled":false}}

And i have enabled an another setting to prevent the extension to be disabled or uninstalled by specifing the ID of the extension : ca613ee6-4211-4ae2-aa3c-d29608461d11

The policies are visibles under about:policies and they don't show any error.

The issue is that i'am still able to disable Lockself but going in Firefox parameters then under password and autofill. On the image attached, the button "Desactivate the extension" is here and you can use it, it disable the extension.

Regards

I HAD TO REINSTALL MY WINDOWS 10. NOW FIREFOX IS TAKING A LONG TIME, IF AT ALL, TO LOAD LINKS FROM MY EMAIL. FIREFOX IS SET AS THE DEFAULT BROWSER. THERE ARE NO ADD-ONS THAT WOULD BLOCK LINKS

I asked AI: "I'm being prevented from using options which cause pop ups but I don't think I've deliberately changed any settings. I want to use "analyze the board" on the Gameknot website but I'm being prevented from using it. How can I get it back?" I followed the instructions: "Mozilla Firefox: Click the three lines (top right) > Settings > Privacy & Security > Permissions. Go to the "Pop-up windows" section and click Exceptions, then add https://gameknot.com" but I haven't re-acquired use of the pop up I ant to continue working. I want it back and its extremely irritating as the work around is very long and boring.
