Diễn đàn hỗ trợ Firefox

When I open the application it loads as a small window that I have to maximize to make it full screen. It never used to do this so I need some help to fix this. I've taken a quick look through settings etc and can't see anything wrong...

my hardware is very outdated already and i wanna try if my firefox runs better without any hardware acceleration like running fully on software.

i don't think that just simply disabling the hardware acceleration in the settings disables the entire hardware acceleration because there are way more about:config preferences which are related to hardware acceleration.

Hey guys,

I saw in the following post that I can modify the zoom values of Firefox to custom values of my choosing (e.g. 75%, 85%):

https://support.mozilla.org/en-US/questions/1201469

I followed the instructions but it did not work for me. Yes, I did save the changes I made, and I completely closed & reopened Firefox, but the changes I made have not been applied for some reason. Please see the attached image.

I would have ask the question in the aforementioned thread but it's been archived so I had to open a new one. Does anyone know why Firefox does not seem to recognize my custom values (.75, .85)? Thanks!

I want to print a page. But without the header and footer stuff (because it is ugly and I don't want others to see the information). There are a lot of old pages here and on other places about how to do this. They are unfortunately all deprecated. What is the way to do this as of 2023? OS is Windows, btw.

While hovering over a Youtube video it shows the full video title as "hover text" if the tab is focused. However, if something else, even another Firefox window is focused hovering no longer shows anything. Is there some kind of setting to change that? I figured it could be browser and Youtube specific because Chrome shows it on Youtube even when not focused, but neither browser shows it on Google search for example, but I'm not sure.

Hello!

I would like to develop an application that runs continuously, say, at a panel found in a kiosk. I am considering designing it as a webpage that runs locally through the browser but I would like to prevent the users from interacting with the OS or closing the tab and the browser. Is there a way to lock Firefox in full screen and hide the exit buttons? Alternatively, do you have another recommendation for development that is more appropriate, for instance a native app?

Thank you in advance for your help.

I have been using (VIEWING articles in // saving articles TO my) FIREFOX "POCKET" for more than a year.

I have the pocket ICON on my upper toolbar. But ALL that seems to do is allow me to ADD an open page TO Pocket. I have NO clue how to simply **Go t o POCKET** and VIEW any / all my saved items there.

Good God, WHAT is the secret handshake??! ...in trying to figure this out I see numerous things telling me to SIGN IN to pocket ... IF way back when I began using pocket I MADE a USER NAME / Password for it, that info is long forgotten. I HAVE a FIREFOX account ... was sent therewhile supposedly (according to Firefox" HELP") to 'sign in' to my POCKET account. Only took me to an overall FIREFOX account page - wherein NO LONK there referred AT ALL to POCKET.

I 'SAVE' to my pocket (ICON) almost daily. NEVER need any kind of sign in for this. NOW I want to LOOK AT / READ some of these - BUT FIND NOWAY TO GET THERE. ICON omly SAVES a page.

Ridiculous. HOW do I VIEW / SEE / FIND /READ my saved pocket items?

In trying to find ways to remove elements, it seems like I need to go the CSS route. I was wondering if anyone could recommend a good tutorial or good videos or something so I can learn how to do it. It looks complicated to me, so any help would be appreciated. Thanks!

I have 3 Gmail accounts that I like to keep open most of the time. I'm trying to migrate from Chrome, which lets me have different profiles in separate browser windows. How can I keep my different email accounts open? When I add one, the first one closes.

Hi everyone,

First of all, thank you for your help you brought me long time ago reading yours answers concerning different others issues. Today, I didn't find the answer to my issue in the historic base of questions/answers...Maybe, I also missed the answer... anyway...

My problem is the following: I have habits to use the unicode shortcut every day (exemple : ä <--> alt+132) but this is not possible if the "Bookmark Toolbar Shortcuts" add-ons of firefox is active because I suppose there inteference with bookmarks shorcut that I also use a lot. So, I have to disable every time the add-ons, which is a boring operation... I tried to modify the shorcut of the "bookmark toolbar shorcut" add-ons but, Firefox send me "you can't override firefox shorcut"....

Does someone find a solution to this problem ?

I found this link which talk about of the subject but without a real answer : https://superuser.com/questions/1322464/how-to-prevent-firefox-keyboard-shortcuts-from-interfering-with-unicode-input

I thank you in advance for you help!

kind regards,

Simon

How to save images to the downloads directory (that I chose in settings) without using right click -> save image as .. -> popup window .. then choose the location where I want to save it.

I tried alt+click, it didn't work, it saves the webpage url instead of the image. I prefer a solution that does not involve any add-ons.

OS: Pop!_OS 22.04 LTS Firefox version: 121.0.1 (64-bit)

Thank you.

How to SWITCH TO TAB when i enter something in address bar and I have this page opened? When I search my question, I get answers like "how to DISABLE...", but I need to ENABLE this feature. Firefox 122. When I type in Address bar something like "google.com" and I already have opened this site in another tab, I want FF to switch this tab instead open a new tab/window. How can I ENABLE this feature?

I autoscroll, using the middle mouse button a lot. I middle click, release the button, and just move the mouse. To stop the scrolling I click the middle button again.

The problem is that in Twitter (only when using Firefox, not Chrome), and perhaps a very few other websites, if I make that second click (to end scrolling) over a link or linked image, the link opens (in a new tab). This is very frustrating, since I can move the mouse anywhere while scrolling, and I commonly mistakenly open links this way, interrupting my reading.

If I am *not* autoscrolling and middle-click on a link in Twitter, nothing happens. (Perfect!) But if I am autoscrolling the link opens (Bad!).

How can I set up Firefox to that the middle mouse button will never open links, and only function for scrolling?

How to block the full screen function permanently at the same time that all menus are hidden, invisible, when you press the full screen button so that the video one gives a larger image without giving full screen. I have previously found a firefox program that could do that, but unfortunately I got it deleted.

Want to use the solution on a Win 10 PC, desktop PC and a screen of 1.5 m, i.e. 2 screens in one.

Hello!

I recently got a new computer with Windows 11 freshly installed. I downloaded Firefox, went to take a screenshot, and the usual shortcut of Ctrl + Shift + S does not work. I can right click and Take a Screenshot, and I can use other Ctrl + Shift shortcuts, like Ctrl + Shift + T to reopen closed tabs. The only one that doesn't work is screenshots. I can also put Screenshots in my top row Toolbar and use it, just not the keyboard shortcut.

I refreshed Firefox, uninstalled and reinstalled Firefox, as well as checked the about:config extensions.screenshots.disabled preference. It has been set to false, so I have set it to true and false again hoping it would "reset" it but nothing. Thank you!

I'm currently developing a website that use user printer. And I'm looking for a hook that I can use to know user click the confirm or cancel in print dialog(or print preview window). the onafterprint method will trigger before user click confirm so I guess it's not an option.

Also, someone please tell me the topic describes my questions, I really don't know which topic is best for my question.
