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.

ich benötige die übermittlung, da das chronic dieses eingestellt hatte: die auffindung der www´s durch das vorgehen bei dem umstellen der mozilla-umsetzung bei der neuinstallation. durch dieses hatte ich die www von einer bestimmten auffindung nicht (ich kann die www gern durchgeben: frau, bdsm, in der nähe, aber ohne kommerziellem hintergrund !).

Seem as if you cannot change the primary email address if the address has been invalidated. What are the options here? I no longer have access to that email address. How do I change my primary address now?

this exact question has been asked last year, none of the suggestions work: I am running Firefox 154.01 on Winux I have lost sound on Firefox. I have opened the same sites in Chromium and the sound is working fine. It's only in Firefox. I have tried several sites including , YouTube, and radio programs, no sound from Firefox. All of a sudden the sound disappeared. The speakers is turned on the volume is up, just not a sound from Firefox. What to do? Right now I had to switch over to Chromium

I set up profiles on my work computer and I have sync set up but when I access firefox on my personal computer I don't have the profiles. Is there a way to sync my profiles as well so I can access them wherever I log into Firefox?

With the latest update to version 155, I lost all my tabs.

In my Settings, Startup, I do have checked "Open previous windows and tabs". This has worked many times after shutdown and restarting.

But this latest update did not start ver 155 with all my tabs. Has anyone else seen this? On Win 11 laptop. Steveg

Currently on Linux, but the problem is probably not OS-specific (although any work-around may be).

What I look for:

I want one setup for work, one for union, and one for personal use. If my work setup would be compromised, union bookmarks, search history etc is not compromised at the same time. Also, my work setup is not cluttered with private bookmarks and addons. Obviously, it'd be nice if those setups could be handled as separate start menue icons, so that I don't need to switch using a couple of clics, but just start the right setup directly. Needless to say nowadays, that these setups need to be syncable between devices. Ideally I as a person would have one Mozilla account that can store multiple profiles and protect each one with a seperate password, OR I as a person would have multiple Mozilla accounts that are made for easy switching.

What I've tried:

Multiple accounts, obviously; they sync between devices, which profiles really do not. The problem I run into is that I still need a separate profile for each account if I don't want to log in and out of them (which I don't want indeed, Alt-Tabbing during my leisure time is the only way for me to get things done for union and often for the office-part of work).

Finding the profile feature was hard enough but I adopted and have the about:profiles page bookmarked in all profiles. But whenever I start using a new computer, I need to set up new profiles. I tried saving them in a custom location on my nextcloud so that they can sync, but there is no straight forward way to import profiles. You need to create new ones and then move the contents of the old ones, instead of just pointing ff to an existing profile; that kind of kills the point of picking a custon location in the first place. All I ever do with a new profile is logging in to one of my already highly profiled accounts.

Along the way I realized that there is a now more GUI-way to create profiles, so I tried that. But when I tried choosing a custom location for them, I failed. Took me a while of restarting and googling to find out that Mozilla has managed to have two completely seperate features with the exact same name! That is, when you create a profile the modern way, it does not appear in about:profiles and vice versa.

Since I ditched the idea of custom location anyway, I setteled with the new way. But when I thought I'd make seperate startmenue links for them, because surely you can handle that with some kind of flag in the command, I could find only one option for profiles, and, as you can guess, it works with the old profiles.

It seems that one can start with a profile at a certain path, so maybe the old way with custom path could be something for me anyway, but when I used such a profile, I got a warning message that says that history and bookmark functions might not work properly and that some security program may cause this.

So, how is one actually supposed to use different accounts OR how is one supposed to sync different profiles between devices?

gerald.r.vargas 4. Aug. 2026, 08:23 GMT-6 Hi, this morning for some reason all the tabs I had open couldn't been loaded. Refreshening the page didn't help either. So I decided to shut down and restart my laptop.

Unfortunately after restarting Firefox only one page and its tabs have been reloaded.  All the others were gone. 

After trying about:support and session:restore it didn't help either, because only the 4th of Aug. was available. Is there a possibility for a session restore from the 03rd of Aug? or the previous days? If anybody has an idea, how to do so, please let me know.

Many thanks, Gerald R. Vargas

my browser.newtabpage.activity-stream.topSitesMaxSitesPerRow is set to 8 , but there are still 10 squares under the search bar. is there any way to change this?

Version 155.0.1 (64-bit)

I've made a related feature request to include an option to force Firefox to give the option to autofill any arbitrary field as a credit card, address, whatever. This is because 9 times out of 10, Firefox either fails to recognize a field and doesn't offer an autofill option, or something else is going on. If I was able to right click on an empty field and select, "Fill from credit cards," this would solve my problem.

I inspected some of these elements and see that they seem to contain the correct type of markup, with the proper autocomplete="cc-number" attribute. So why is Firefox not recognizing that field? Why is it not popping up an option to autofill?

tl;dr: there is no option to autofill even on correctly marked-up forms. Nothing pops up. My credit cards are stored correctly, I'm logged in as the correct user, the feature works on *some* checkout forms, just not most of them.

edit: I don't know how to delete this. turns out this is a known bug on firefox on linux. Firefox cannot actually save payment info, but doesn't serve an error to the user. however in the console it will throw a NS_ERROR_ABORT error: "User canceled OS unlock entry" error when it tries to save. the one solution i looked at seemed way too complicated for me so i am simply going to give up and try to keep my cc closer to me and not get frustrated when it doesn't work.

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

Ive been FIGHTING to get business done on ROKU website. IT continues to switch to SPANISH. I am in the USA. I no longer am subscribed to ROKU in SPANISsince several months past. I figure a BLOCK for other languages would do the trick.IS there such a thing. THERE SHOULD BE!!! Thanks
