Firefox Support Forum

I have one site that produces PDF files that Firefox will not open correctly, my other browsers do not have a problem with PDF. What should I be looking for to correct.

Hi there,

In the search settings, I have set DuckDuckGo as my default search engine and removed all other engines from the list of options. However, I often notice that Google (which I have removed from the options) has replaced DuckDuckGo as my default search engine and has again been added as an optional search engine, without me knowing. Why is this happening? Is it possible to stop it happening, and if so, how can I stop it happening?

Cheers Paul

My Norton virus detection software regularly finds viruses and Trojan horses in the directory: C:\program files\Mozilla Firefox Why?

It seem to happen after using Facebook or more often Craigslist. I tried putting a read only attribute on this directory, but it still happens.

Norton then requires a reboot. So it is a hassle.

Does anyone have any ideas as to what is going on?

Just a couple of quick questions for CSS coding as of Firefox 115:

What CSS code refers to the shield, padlock, permissions, or all other toolbar buttons in the address bar?

When using control to select multiple tabs, what code refers to the outline and text color of the tabs?

Images attached for reference.

Thanks in advance!

I have used FireFox for years Now I can not download VPN as it requiers W 10+ I can not afford new computer, I am a Disabled Viet Nam Vet/ A MARINE I dd not what all these new apps and maybe Windows is blocking download - HELP

I'm still using windows professional 7, it works for the most part. Unfortunately often the browser won't load or it will load and runs very slowly, then it shows a box saying close previous firefox. When it is running slowly I often have to hit the browser many times until the box shows up saying close previous firefox. Is this something to do with windows 7 or another completely different issue.

I start Firefox from a batch file (Win7) on the first boot of the day. Manually I choose my "NEWS" bookmarks folder, then slide down to "Open all in tabs". (attached image) (Then I go pour a coffee while the news article tabs open and load data!)

Please and thank you, is there a way to specify this action from the command line? And if so, what is it?

I believe that I could use such a mechanism in other ways, such as opening all tabs in my "Forums" folder of bookmarks, or on Mondays, opening all tabs in my "Weekly" bookmarks folder.

Thank You, Chris

I tryed Firefox 115.8.0esr and 115.9.0esr 32Bit on Windows 7. (78.15.0 works) Firefox crashes(the whole program, i mean no tab) on "about:support" or some pages on support.mozilla.org like https://support.mozilla.org/de/kb/firefox-leistungseinstellungen always reproduceable.

I disabled all Addons, i disabled this power optimizion setting, removed usercrome.css same. With Firefox savemode it dont crash. Spyware is blocked, means datareporting/telemetry/ping by disabling the options and empty the urls (like on FF 78 but it dont crash). Somewhere i read firefox can crash on a empty url, but i assume its fixed long time ago. A wrong, unreachable or empty url should not crash on well programming. Think about countrys that blocks urls, adblocker, pihole and so on. I dont remember about what url i read.

Does the savemode revert all about:config settings? What does support.mozilla ask the browser that causes the crash? It know it seems to identify the Browser, but usual its done by useragent and no "internal" communication.

Then FF always crash on ebay.de search if you scroll or change settings while the page is not ready. Spyware is too blocked by Hardware, ebay may wait for some ad? But thats already on FF78 but on 115 it seems more often, this was not with FF 52. But some sites including ebay stops to work with FF52/78 so no choice.

I noticed that after the recent updates, the pop-up notification for blocked pop-ups has changed from yellow to white.. This makes it very difficult to see and I almost missed it. Is there a way to revert this change using userChrome.css?

I don't understand why this unnecessary change was made. I already have my own userChrome style for the entire Firefox because it was frustrating to constantly change it back after each update.

I would appreciate any information on how to revert this change.

Thanks.

Hello,

In Windows 10 and 11, Firefox's tab bar and other elements that may be transparent render in Windows 10 using some sort of uDWM method (speculation, I could be wrong?) rather than the traditional win32 window frame as you can see with the title bar toggled on. This leads to elements like the tab bar being black or white, depending on your theme unless you have specified otherwise in your chrome. Highlighted yellow below is my problem area.

In my CSS code, I am trying to extend the system color to be drawn to the tab bar (and in this instance, the address bar as well,) but I can't find any way to be able to do this. I have found forums that say to add -moz:appearance -moz-windows-glass, but this completely removes the window border and leaves the Firefox window unresponsive to controls. The only way to close it is if you close it through the taskbar or task manager.

Note that I am aware of .titlebar-color{color: AccentColorText; background-color: AccentColor}, but that's not what I am going for here. That still draws using Windows 10 modern UI. Windows 7 on ESR 115 or unofficially on 116 still draw with Windows Aero in all parts of this CSS code that are black (highligted yellow below.)

I can attach my CSS code if need be.

Thanks for any help!

When I check Firefox for add ons (Manage your extensions), I see the two that I installed. When I use "Help -> Troubleshooting Information" "Application Basics": Multiprocess Windows "Remote Processes" , I see in addition: Amazon.co.uk Amazon.com DuckDuckGo eBay Wikipedia

How do I eliminate these?

Hey folks... I am running the latest ESR version for windows 7. I know, its limited support and stuff but I have this most annoying problem that just doesn't seem to want to go away.

Every day, several times a day, I am told there is an update available. I have gone in several times and downloaded and installed the latest release. The install goes fine, there are no issues. Yet, over and over again I am told there is an update... but I have the latest version installed.

In the past, I have used the "distribution" folder trick to stop updates and I have removed that a long time ago. I can't figure out why it keeps telling me there are updates, when there are none.

How can I stop this from doing updates where there are no updates to get? It's driving me nuts...

Hello. I suspect there was a cyber attack on April 1 2024. All of a sudden,having problems crashing with more than 1 browser. My Brave browser would open,and then crash with multiple tabs that had been saved. My Mozilla history was cleared,and I want it back because I need to find all sites I have visited from time to time for logins etc,but they are now gone.I have tried importing all of my Brave history,login forms to Firefox,but not sure where to located them or where they would be stored.

Right now i am focused on getting a Firefox profile from before April 1

I have never had to deal with this sort of thing before so i am saying that i may be somewhat noobish on this.I just want some expert instruction on what to do here,and how to do it.I,m not 100 percent sure if i can do it correctly on my own by googling this myself,then attempting it.Brave continues to open then crash right after,so I dont know whats going on there with the userdata folder in the appdata folders with regard to Brave. Everytime i try to install an older version of Brave,it says i already have a curent version of it,and i dont want to uninstall brave then reinstall it again,or not sure if i should do this. ThankYou.
