Firefox Support Forum

Hello there, Iam facing a problem with changing Firefox homepage background. I tried every solution, tutorial, oldposts etc. nothing seems to work, here is what I tried. -1- The chrome folder is in the right folder. -2- the naming of both CSS files userChrome, userContent. -3- enabled CSS files at startup -4- search for both CSS files in the browser toolbox for some reason I cannot find both CSS files, even though they are in the chrome directory. Also, I have 2 chrome folders one of them is located here. "AppData\Roaming\Mozilla\Firefox\Profiles\shaf5qn0.default-release\storage\permanent\chrome" the other one I created myself which is here "AppData\Roaming\Mozilla\Firefox\Profiles\shaf5qn0.default-release\chrome" I tried to delete the first one but I cant, I get an error that this file is being used even though I did close Firefox. What I am missing here?

My default search engine was Norton Safe Search but now it does not appear as one of the options to choose. I cannot remember all of them. Bing and Google are two of them but not Norton Safe Search although I have been able to add it to the toolbar. Why is it no longer one of the options?

I use several add-ons in firefox, and largely they feel trustworthy, but I dont have any means for limiting the scope of what they are able to do, the manifest tells me what they can do and thats it. I have read through this page https://support.mozilla.org/en-US/kb/permission-request-messages-firefox-extensions, but I have had a hard time even understanding which permissions let an add-on make network requests.

Barring the ability to actually stop add-ons from making network requests is there any visibility into what requests are being made by an extension, or all extensions in the browser?

Please provide a native way to change the behaviour of Ctrl-W. I tend to switch between aZerty and qWerty keyboard layouts, as a result I sometimes hit ctrl-W when I would like to ctrl-Z some change. As a result I tend to lose some work when the tab I'm working in closes. It would be nice to be able to rebind some of the default key combinations, or at least disable them.

I found a method description that edits the omni.ja file, but also that this method is unsupported. Moreover, running ubuntu kind of rules this out as an option, as canonical has ruled that firefox is to be installed via snap, in a read-only data store.

I was able to customize my new window to display www.google.com however I only have the option to select "Firefox" or "Blank" for new tabs. I would also like new tabs to open to www.google.com. How can I do this?

Hi,

As the subject says, i cannot remove the up and down arrows from forms that have a numerical input even though autofill/history options are cleared and disabled. I've even tried deleting cookies, cache, site data and so on, to no avail. I've also tried a clean terminal with no extensions installed and i have the same issue. Other browsers do not have this issue on the exact same form. I am at a loss, any assistance would be appreciated.

I have Startparge set as my default search engine. I used to type directly into the address bar (see first image).

Press Enter, and the Startpage results page for this search phrase would show up. Somehow, this has now changed. I press Enter, but the result is just the Startpage home page, with a blank search box (see second image). So I then have to type the same phrase in again in Startpage's own box. This just trips me up.

The crazy thing is that this only happens sometimes - but more often than not. I haven't seen it work right for weeks: I just did it now to make screenshots, and it worked wrong. I just did it again and it worked as expected: pressing Enter took me to Startpage's results.

Any clues how to change settings to fix this?

firefox is using so much memory that it is causing lag and loading problems.

i know that the root of my problem is that i have an unholy amount of tabs open all the times but if i go into the process manager for firefox i can see that the memory problem is actually usually only 1 or 2 tabs that are using over 1GB of memory. this has only been a problem in the last few weeks so i am not sure if something has changed on the firefox side of things.

I looked into tab unloading and this seems like it would solve my problems. however the unloading process only happens automatically when the total amount of memory that firefox is using approaches the maximum amount of memory you system has available. with 32GB of ram and firefox reaching not even 16GB when completely stretched the automatic process will likely never hapen. yet firefox is still using enough memory that it is causing itself problems.

i dont really want to have to unload my tabs all the time to keep firefox's memory in check. is there anyway to lower the amount of memory that causes firefox to automatically unload tabs? i have seen extensions that say they will sleep tabs that are not being used. however they all seem to just sleep tabs that are not currently in use rather than sleeping tabs that have not been used that day.

i feel like the tab uploader is such a good feature in firefox that i would love to be able to use it to solve my problems. however i am not sure how to make this happen in the laziest way possible.

I have a content filter to filter out inappropriate material. Included in the filter are filters for adult content on wikipedia, youtube,and google podcasts. however, all those sites are fully allowed on Firefox, as opposed to on Safari and google chrome where the filter is working properly

I use a public computer often, and I would like to use certain customizations while remaining anonymous. Rather than going through and clicking a bunch of checkboxes, I decided to have a hot key combination to enter in order to obtain my desired options. For example, I want to allow new windows to open normally, I want to choose where files are saved, and I want to turn off Firefox's recommendations. The underlined hotkeys are, respectively, ALT+W, ALT+A, and ALT+R ALT+F. So rather than a bunch of scrolling and clicking, I could just type ALT+WARF, and get the options I want quickly.

However, pressing the hotkeys while in the settings does not seem to do anything. In particular, pressing ALT+WARF only succeeds in pressing the ALT+F, which opens the File menu. Pressing these keys without an ALT key sends them automatically to the search bar -- which is also not what I want. Pressing ALT+SHIFT focuses in on the checkbox -- but does not press it. For example, ALT+SHIFT+W focuses on the checkbox, but I still have to click SPACE after it to press it.

Is this a bug? If not, how can I make the underlined keys press the respective checkboxes?

When in fullscreen, if I move the mouse to the top-left corner and right click, a browser context menu appears. The page I'm on is using mouse right clicks, so this browser function is breaking the controls of the page if I ever accidentally click the top left corner (which I do often).

Is there any way to disable this menu appearing? I would never use this menu to minimise/close the program so I just want it gone. It's breaking fullscreen controls in it's current form

When I click on a pdf file, Firefox opens and displays the file, rather than handing it off to Acrobat, which is my preference. I'm running Firefox 122.0.1 and Windows 11 Firefox seems to ignore the settings in General, Applications. (See attached image)

    If I set to Always Ask, Firefox displays the file without asking.
    If I set to Save File, Firefox does not save the file.  It displays pdf instead.
    If I set to Windows Default Application, Firefox displays the file.  
         (Note: Acrobat is set in Windows as my default app for pdfs.  If I find a pdf with Windows Explorer and open it there, Acrobat is launched and it displays the file.  IOW I've confirmed that Acrobat is set as my default app for pdfs)
    If I set to Acrobat, Firefox displays the file.

I see nothing in Firefox Settings showing an Add-in for pdfs Any ideas?

Hi, I am trying to install an add-on for MetaCert. I receive the following from Firefox: "Check This by MetaCert by MetaCert". This does not help to install the add-on. This is not a problem on my other PC. Look forward to your help/suggestions. Best, Stephen Rodgers

hi

For several days now I have been receiving the message "Automatic activation of filters". It goes away after a few seconds but is extremely irritating, how to turn it off?

Hello, In old versions of Firefox picture-in-picture mode was "always on top" by default, now "always on top" mus to be enabled every time I pop-out every video. Is there any solution to make picture-in-picture mode "always on top" by default?

Po przeinstalowaniu systemu i wgraniu Mozilli mam problem z otwieraniem plików. Brakuje mi możliwości jak ze zdjęcia, które jest z instrukcji jak to robić. Przykładowo pliki .pdf zapisuj się i otwieraj od razu, wszystko fajnie. Ale już pliki .msg czy .eml nie chc otworzyć się automatycznie w Outlook'u i nie widzę nigdzie opcji zaznaczenia "zawsze otwieraj podobne pliki" czy jak to tam szło dokładnie. Bardzo proszę o pomoc gdyż bardzo mocno utrudnia to pracę i użytkowanie przegladarki.

Am running on linux with KDE. When I press the software shutdown button in KDE, and reboot, the tabs in firefox remain, even though I disabled that from happening in settings.
