Firefox Support Forum

I used THIS link to change mousewheel.with_control.action to 5, which allows for using the scroll wheel to pinch zoom. My only issue is that it is extremely cumbersome, with 3 full rotations of the wheel required for a 2x zoom. Is there any way to increase the amount per tick it zooms in by?

if firefox is present on my computer it allows roboform to open websites but will not allow login to be completed even in microsoft edge or firefox If firefox is removed roboform works fine in microsoft I have uninstalled firefox several times and reinstalled to no effect including roboform as a FF extension

I'm hoping the developers of Firefox see this...

There are far too many context menu items that I neither need nor use. I would like it to only show those context menu items that I make use of, but there's no way to do it. I would like to see future updates or iterations have this incorporated as part of the Settings.

I know this may not interest you, but it really bothers me that I can't share the page with sound. Please help me if possible or add such an option. For now, unfortunately, I have to use other browsers that have these functions. Regards

Honestly I don't have a clue as to where to look to resolve this sudden issue because I've never seen it before. While testing a simple single page static web site firefox keeps loading the same page into a new tab and a rate that I cannot keep up with. In a few short minutes there are hundreds of tabs open each with the same page. I've tried cancelling Firefox, rebooted my system, even removed and reinstalled firefox all to no avail (using Linux Mint). What's interesting is that all other browsers I try do NOT do this. They all work just fine. Any thoughts, ideas, suggestions as to what might cause this and/or where to look to diagnose? Thanks in advance.

I have some issue with spacebar on some sites with firefox. like in google search, the spacebar refuse to display two or more blank space in a row when the bar is pressed more than once. instead each press is added in the same blank space. means for example if i press space 4 times, only one space appear, but to delete that single blank space i need to press the "back space" key 4 times.

Similar problem with the search bar on the cookie setting (the page in preference where you can manage or delete your cookie list). several time the search bar doesn't write the letters i type. But copy/paste a text work, only keyboard doesn't work. I need to close and re-open the tab for the keyboard working again on the cookie list search bar.

Currently, the width of the browser window is 958px, but why is there a left-right scroll on the YouTube page and a margin remains. I can't even erase it from the developer tool, is there any way to get rid of it? The scroll moves every time I pass YouTube time, and it's so uncomfortable.

New window opens in maximized but new private window doesn't, turning on and off privacy.resistFingerprinting in about:config solves the problem but for unknown reasons it happens again.

Video on https://www.abbeyroad.com/Crossing is suddenly unable to be played after to last Firefox update!! This has happened several times in the past but after 2 or 3 days it suddenly will start working again!!! It's been over a week this time and no resolution yet! Note following LARGE ROTATING X is: "The media could not be loaded, either because the server or network failed or because the format is not supported." Same note as in the past but eventually disappears and video works just fine. The video is a live shot of the Abbey Studio's Crosswalk (ie, the one shown on the cover of a Beetles Album years ago).

Sometimes in the background firefox will start to max out my ram usage (32GB). I am not sure if it is a addon or a site which is doing this. I captured a memory measurement, but not sure what to make of it. I don't have anything to add up parts or anything.

What is weird, is when I go back to firefox and tab through my tabs it will go back down to a reasonable level.

Firefox use a lot of CPU time ( it reaches 100% ) while watching youtube videos in 720p on Windows 10, and videos lags and stutters too much. Not using any ad blockers, non of plug-ins are on. It does work just fine on Ubuntu on the same machine Vids also were working fine on previous popular web browser known for its spyware

Using hardware acceleration is on in browser settings. Specs are: CPU: Intel(R) Core(TM) i5-3230M CPU @ 2.60GHz 4,00 GB x64 Windows 10 Home edition 22H2 GPU: NVIDIA GeForce GT 635M

Firefox version 120.0.1 (64-bit), up-to-date

Hello, can you add better support playback on .mp4 videos? Seems with Firefox it's a hit-and-miss with some .mp4 videos that will play and some that will just show "No video with supported format and MIME type found".

All other browsers will play .mp4 videos without an issue but Firefox won't.

If you can provide better .mp4 playback support that would be greatly appreciated. Thanks

Here's one of those videos for an example: https://drive.google.com/drive/folders/1Fv6SdftiCXeYPQOdF17H2JNpwjMu9P7q

Pretty much a URL string like example.com/videosample.mp4

GOOGLE SYNCED WITH MY FIREFOX AND REPLACED ALL OF MY BOOKMARKS AND i CANNOT GET THEM BACK AND THEY ARE FIREFOX SPECIFIC WITH PASSWORDS AND ALL. PLEASE FIX THIS. i HAVE TRIED MULTIPLE TIMES UNSUCCESSFULLY

Why am I seeing pop-up windows with ads for this online women's cloting store: https://www.lightinthebox.com

I have been using Simple Tab Groups (STG) for a long time now. I am curious if putting tabs into groups saves any resources, i.e. is only the open group using resources (CUP/RAM), or is STG purely organizational in that all the tabs still use the same amount of resources as if they weren't grouped? If it is the latter, do you know of an add-on that would save resources? Thanks

Everytime I go to play games on my laptop I close Firefox for the extra resources and when I'm done I open it right back up, I have done this for YEARS but this time it didn't restore my session. I thought it would be as easy as the last time where I'd go click the Restore Session button but it isn't there so I spend two hours looking for solutions and found nothing. I don't know how this happened nor do I understand how this could happen in the first place, my Firefox hasn't crashed in months and I had already closed and re-opened it several time today.
