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.

I don't know which topic describes my question. I want to put the New York Times as a short cut on my firefox home page and it won't do it. For a bit of history, I USED to have the short cut and one day it was removed by Firefox when it re-arranged things.

firefox suddenly stopped showing any history or book marks. also no history. i've re downloaded, no change. all works well with chrome but i like firefox. and thoughts?

I have disabled and removed any and all VPN's from my main unit. I have reloaded Firefox and cleaned the registry. Still getting the message and am unable to display images. Any ideas?

Whenever I open a new firefox page externally, such as from the system tray or by opening a link from outside firefox, nothing happens for about five seconds and then it loads normally. When I open a new firefox page internally, such as from file ---> new window or by clicking a link within firefox, it loads instantly like normal. This has been happening since yesterday (3/13/26) evening.

I have already tried all of the following fixes and none have done anything:

Clearing firefox startup cache running firefox in troubleshoot mode running an older version of firefox disabling all my extensions disabling my antivirus disabling hardware acceleration disabling captive portal detection making sure both firefox and windows 11 are fully updated refreshing firefox reinstalling firefox rebooting my PC disabling IPv6 preventing accessibility devices from accessing my browser clearing my cookies

Running into more sites rejecting FF as my browser. Latest as of 4/14/26 : https://carespaceportal.com/chart Had to click to ignore notice to switch to Chrome. Site seems to function w/ FF 149 so far when i log in. I used MS BING search points to extend my Win 10 edition Desktop computer 1 year... There was no mention about my MS Win 10 edition. I'm logged in,,Not sure why this FF page "unable to pull your browser’s troubleshooting data"....

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?

So scheint ständig bei E-mail Posteingang.?

When opening the "Show all history" window (command Y) the text is garbled. I have checked the font book and there are no duplicated and I have validated all fonts. I have tried using the troubleshoot mode and occasionally the text is rendered correctly but mostly it has no effect. There is no other location in the browser where the text is garbled. I have tried changing the text in the advanced settings and both performance settings are disabled.

The first time i'm installing Firefox it quickly made me fall in love with this browser and wanted to fully migrate from Chrome to Firefox, it's more lightweight, has more customization, fully private & secure. But there is only one thing that made me just almost migrate to Firefox, or just 99% complete transitioning to Firefox, and that is me unable downloading. Yes, thats it and it's pretty annoying. I just able downloading pictures, but not when i'm downloading an apps or software like Discord for example. PLEASE HELP ME, MY LAPTOP (X240) IS VERY OLD AND I NEED EVERY PERFORMANCE ON MY LAPTOP FOR WORKSTATION PLUS WITH THIS RAM PRICES (ykwim). Tomorrow i'm planning to switch to Linux (Mint MATE) and i have to do dual-boot just incase there is some software i'm unable to use at Linux. So please, help me. Give each step with no technical explanation, and use beginner languange so i'm easier to understand.

How do I stop my search results from suddenly becoming shortcuts on my home page? This is something that has started relatively recently & I did not request this or change my settings.. The only thing I want on my homepage is actual saved sites that I choose to have on my home page. I now have to spend time every session deleting the history of these unwanted shortcuts from my homepage. Any suggestions would be greatly appreciated. Just searching for how to stoip this has added this search as a shortcut to my home page- see attached pic.

I recently refreshed my FF installation. Before I did that I had configured my tab settings to always display the x icon (close tab) in all active tabs. After the refresh, the x icon is gone for all tabs.

I cannot remember what I did to get them to display originally. I've tried to do this in the userchrome.css file. But it didn't work. Let me know if you have a solution.

I play a game on Facebook - and i go to it from a link in my email - but today it says your browser does not support WebGL - this happened a month ago but I forget how it got fixed. :-(

it worked yesterday - and I checked for Firefox updates and it is up to date. last time this happened - I did read an article online that suggested to go to put about:support in the address window and under General it said to uncheck standard performance and to click on "use accelerated performance" - that fixed it.

This time when I go to about:support - "Use Hardware acceleration when available" is already checked. How do I fix it this time? and why does this keep happening every so often?

I'm having trouble with the ui elements on firefox, the min/max/close buttons are showing some random characters and the menu also shows an "Á" besides some options.

Here's what I tried: reinstalling, clean reinstall, delete start cache, fresh restart, troubleshoot mode, On windows: restore font configuration, sfc /scannow, dism cleanup-image restorehealth, deleting all aditional installed fonts and saving only system included fonts.

Still, the font on tabs and some menus looks strange, and the problem with buttons and menus keeps happening.

I don't really know what else to do

I'm running Firefox 147.0.2 on a 2020 MacBook M1, with Tahoe 26.2, and appear to have 2 versions of 'identical' Firefox on my machine. Applications shows only 1, but there are 2 distinceticons on my Tool Bar. I'd like to delete one of them, but can't do it successfully. Any help appreciated!
