the preference "browser.contentblocking.category" does still work although it isn't existing in the about:config settings anymore(was removed as it seems) but how and why does it still work?

Every time I open anew a page it invariable displays the page somewhere mid-way down requiring me to scroll up to the top (if page is large enough to warrant a scroll). I'd prefer every page open at the top at all times. Is there any switch in the configuration editor that would allow for this?

Thanks -Ej

my hardware is very outdated already and i wanna try if my firefox runs better without any hardware acceleration like running fully on software.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

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.

How can I get rid of an automatic fill of websites visited. When I go to the address bar and type in an address, I want to get rid of a website as I have no interest in having that automatically show up on my address web sites. I am using the most up to date Firefox version on a Windows 10 Microsoft Surface Pro computer.

Dear Anyone.

So I got ransomwared awhile back - the AZQT one - and managed to get out of it with copious use of backups! Thing IS - it's left my Outlook/Hotmail E_mail page in Russian - and I can't select 'change to English' because all the sub-menus are in Russian and I don't know what to click on!

Now when I first load up the page, I get a lovely-looking little box 'Firefox has detected this page is in Russian, would you like to translate to English' (or words to that effect, y'know.) But the box appears and disappears so fast I don't have time to click on it. I managed to get to it a couple of times and it worked perfectly. But normally it vanishes before I can get there.

How do I make the little box stick around longer so I can click on it? Or is the same option hidden in a Firefox menu somewhere - I'm not the world's greatest Internet browser geek, so please keep answers simple! - and I could click on it in a Firefox menu? Like I said - if I GET to it in time, it works like a dream. It's just GETTING to it fast enough before it vanishes that's the problem!

Just ad an 'orrible thought. I hope that if it's in a Firefox menu, that's not been turned into Russian too!

Yours respectfully

In my "Themes" section viewing the add-ons manager, I can view all the themes I have downloaded, and I would really like to disable the recommendations. They are not relevant to me, and they take up space and are a distraction from those I am interested in. Is there a way to disable the "Recommended Themes" section???

How do I add a link to the start page that shows when you open a new tab? I've read support docs and I don't have a "pin icon" on my toolbar... I'm on MacOS (M1) and latest (Feb '24) FireFox...... how can it be so non-intuitive? I can't find an option anywhere...

After the last couple of updates Firefox will not wrap words in view source screen(CTRL+U). This makes the info very difficult to read as most lines of code run off the screen. How do fix this? Thanks.

Whenever I open a new tab or window, I'm greeted with the Firefox home screen, which displays various shortcut tiles.

Currently, I have a shortcut for Amazon, which includes a handy blue magnifying glass symbol 🔎 indicating it's a search shortcut and not a shortcut that will take me to an URL. I'm looking to set up similar search shortcuts for YouTube and Google. I've attached an image below for reference.

If anyone is familiar with how to customize these search shortcuts in Firefox, your guidance would be greatly appreciated. Please let me know if you have any tips or steps to follow.

Double page (side-by-side) viewing of PDF documents in Firefox (Windows), involves:

   go to View in the top menu, select Page Display, and choose “Two-Up”

How do you view such double pages in Firefox (Mac), since it seems not to have a "Page Display" facility?

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.

on some websites it says -1 tells Firefox to automatically determine the size of the cache based on your physical disk and setting it to 0 would effectively disable any disk cache entrys.

so are this informations true and if not, how do i still let firefox automatically determine the size of the cache based on my physical disk?

The latest version of Firefox I have keeps making changes to my computer every time I open the program. I have to approve the changes each time, why is the program suddenly doing this? What does it have to change on my hard drive? I don't like programs making changes to my computer when they open they are usually not to my benefit and add clutter to my computer. Please answer, so far no replies to any of my questions!!

Every time I right click and select "Open Link in New Tab" Firefox is not opening this new tab next to the current tab. It instead moves this new tap to the end of all the tabs (of the current website). This is an annoying behavior, I have to go all the way to the end of the tabs to look at the name page that I just opened. How do I fix this behavior?

Hi, I discovered that in order to achieve that, you set in about:config "permissions.fullscreen.allowed from the default false to true. The default behavior does not stop the video with a single left mouse click, but triggers full-screen. It would make sense to make "true" the default as it seems more intuitive to control both the play and full-screen in that way.
