Firefox Community Forum

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.

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.

For the last couple of days, the address bar on the web apps that I've installed to my taskbar has been shrunk to about a third its usual length. I don't have flexible space put anywhere on my toolbar, and the problem is only on the sites I've put in the taskbar, not in regular browser windows. Is there a way to fix it, and get it back so it reaches all the way to the extension icons?

I'm using Firefox 147.0.1 on Windows 11, Version 25H2, Build 26200.7623, if that helps

В Гугл браузере игра работает. однако. мне удобно в вашем браузеое.

Firefox browser has stopped opening websites on my Dell laptop. Get "secure connection failed" error message. Other browsers work just fine. I have refreshed, uninstalled and reinstalled Firefox from both firefox website (using Brave browser) and from MSN store.

My name is Nichael and I'd appreciate assistance. I changed computers yesterday and then downloaded Firefox. I prefer the old appearance with bookmarks listed vertically in a sidebar as opposed to them listed horizontally along the top. Which setting(s) will change locations of the bookmarks to what I prefer?

Thanx in advance, Michael

Google Search CAPTCHA persists unless you sign in to your Google account. This only happens in your browser, from versions 140 to 149. Other browsers don't have this problem. Changing the user agent used to help. Now, nothing works.

Why cant I set it to always translate spanish to english??? That option is greyed out and every time i encounter a spanish page I have to manually translate it. Im getting tired of that.

Relevant to Firefox running on Ubuntu 22.04 Linux and an x86_64 platform.

Until roughly 2/2026, it was possible to load a security device by opening Settings, Privacy and Security, Security Devices, then browsing to a shared pkcs11 shared library, in my case /usr/lib/x86_64-linux-gnu/opensc-pkcs11.so, and clicking Load. The shared library would load and would be loaded subsequently whenever Firefox was started. For roughly the last two months, Firefox would pop up an error saying it was not possible to load the security device, but it would actually be loaded and it;s functionality would be available for the current session. For the last two weeks, the library would load without error, but only for the current session. Starting on 4/13/2026, some functions in opensc-pkcs11.so work, but not others. For example, it is no longer possible to connect to MS Teams web interface.

Since changing profiles, which I regret immensely has created a problem when I want to completely clear all history despite choosing the correct settings under privacy and settings. The only box checked the does not clear is the temporary cache files and pages. Even in the menu bar under history and I choose history and clear all history it does not function. I have to manually uncheck the box and check it again and enter clear. This is frustrating, because this has never happened before. FYI, I do not use the AI feature.

Lost Mozilla as my default browser after accidentally opening my Facebook page using Edge. The only site that is corrupted is Facebook. All others work properly. I still want Mozilla. Looks like I've created a newer Mozilla account even though I used my password to open my account using my email address and password. My profile name has changed. Wondering if problem occurs because account is shared with my husband and our account is under his name/email. Any suggestions appreciated. We do subscribe to Norton. Thanks.

Hello, Firefox has been giving me some troubles lately and I can't figure out how to resolve the problem. Since I haven't found any way to consistently reproduce crashes, it is very hard for me to tell if Troubleshoot Mode also experiences the crashes, and the time I can spend doing that is very limited. As previously stated, it is very inconsistent, but relatively frequent, sometimes it crashes very soon and several times in a day, others it doesn’t at all. Sometimes it crashes with several tabs open, sometimes with only one; sometimes it crashes while using a webapp, others it does so on the newspaper page. It might be more frequent while there are Electron Webapps open, but it's more a hunch than anything, since sometimes it happens without those. I have followed the steps in: https://support.mozilla.org/en-US/kb/troubleshoot-firefox-crashes-closing-or-quitting Been unable to find the cause so far. Here is the crash report ID from the latest crash: bp-60cd6ea9-9bd1-411d-a0ca-2f6fd0260415

The crash report does include information on my system, but please let me know if any other information might be useful.

Thank you very much in advance and I hope you're having a great day.

I tried streaming to my sister's PC. Her browser defaults to Firefox which I didn't notice until later. WinTV 10 Extend streamed for over 2.5 hours. I then changed to stream using Microsoft Edge. It streamed for 5min and 13 sec and then got the same audio distortion as on my PC.

I tried to install FireFox on my PC but found it is a newer version. My sister's FireFox version 142 is from August 2025. This newer version 149 I installed shows the streaming bar loading but never begins to play the video. A circle of dots spins on the normal video viewing area, as if trying to load the video.

I believe that all these Browser platforms have been adding so much additional security measures it is preventing normal streaming possible. I can't even stream YouTube videos on my newer version 149 of FireFox.

I tried to find a FireFox support chat line with no success. I would assume there is a way to allow video streaming by creating exceptions.

Not able to create new tabs on this Firefox browser on Home computer while the same is working fine on my handheld. The tabs are synced between the devices. Moreover, after I switched back from Vertical tabs to horizontal these issues cropped up and they are persisting after multiple browser restarts as well.

My home desktop computer is asking for a network login to access the internet today, after FireFox crashed. I do not see anywhere to login. Please help. I have a Mini Mac. I am at a library as my internet is not working.

• Since the last update the "File" menu choice disappeared. I used to use this to share (email) web pages.
• I restored the "File" toolbar eventually and can share with that again. However...
• The right-click menu on the tab Share selection does not work (it shows a list of email apps but does not include mine)
• My default choice (mailto) is properly set up in the Settings (in both Mozilla and Windows) so something is broken in Firefox.
• Adding the Share tool to the toolbar gives the same wrong result... shows a list of programs but does not include the default

I have Firefox on two computers, both on Windows 10. One has a bug, so I need to re-install it. My Firefoxes sync, so I am afraid that if I delete the buggy Firefox and reinstall, I will loose my bookmarks. How do I avoid that? What procedure would avoid that danger?
