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

All of my bookmarks; hundreds of them, disappeared from the folders that appear along the top of the task bar and the folders are now empty. I cannot locate a backup file which is supposedly saved automatically and the appearance of a folder on my desktop titled "old Firefox data" doesn't help resolve the situation. I need help recovering these book marks if possible.

I like to use picture-in-picture mode to watch a YouTube video in the corner of my screen while editing an image or playing an online game (since I like having something to keep my brain active while I'm doing something). Recently, however, this has resulted in my computer locking up. I don't really know how to describe it succinctly, but audio becomes super stuttery and it takes a second or more to render a single frame. Last night this resulted in the loss of an in-progress image (don't worry, I took photos of my screen so I could recreate the image), so I want to figure out how to stop this.

Just to cover my bases, here's my specs:

I am having trouble signing into some of my web sites. This problem just started. I have tried everything even uninstall and re-install. Nothing works. What do I need to do?

I have always been able to watch "NPR Watch" video clips. It was not functional on my new iMac with a new install of Firefox 149. I checked my laptop and it was fine on v147, but when updated to 149 it too was not functional. Please provide a step by step fix. I tried fixes available on internet without luck

the browser seems to not render emojis at all anymore instead showing them as blanks browser wide, while other browsers such as chrome and arc and the OS itself are handling it quite well and okay

I'm on windows 11

in the image included, right is chrome on the same website

Latest version of Firefox on macOS, Mac Mini M2 - 8 GB RAM and MacBook Air M3 - 16 GB RAM: Firefox malfunctions on launch - I have to force quit and relaunch it - Firefox starts to load then freezes. Firefox works, then I launch other applications like Chrome, Thunderbird, etc. Firefox freezes on the M2 8GB RAM but rarely on the M3 16GB. A few weeks ago, these problems didn't exist on either of my Macs - since an automatic update that I didn't notice, it's now a consistent occurrence.

How do I completely uninstalled Firefox and revert back to the previous version, and turn off auto updates?

When I try to log into twitter (X) I get a pop up saying I'm blocked due to suspicious log in activity, that I have tried to log in too many times. I had not tried to log in for days. I do not get this message and can log into X on other platforms, including chrome and Edge. I prefer to use Firefox. This started happening after I uploaded the newest Firefox upgrade on 3/3/26, I run windows 10.
