Hello! I would like very much to change or disable some of default keyboard shortcuts. For example:

Ctrl+I  - it opens popup with page info. I don't need it, and I would like to use it for one of my add-ons (Instapaper). 

I know, that I can change shortcuts for Add-ons, but I would like change some of those too: https://support.mozilla.org/en-US/kb/keyboard-shortcuts-perform-firefox-tasks-quickly And I dont know how to do it.

Thank you very, very much! Aneta

I use my monitors in a vertical set up, one on top of the other. When I have a firefox window maximized on the bottom screen, the top of the window extends too far and ends up covering the top screen by 8 pixels. I've tried renaming xulstore.json, and while that does work, it ends up being too large again by the end of the session. I'm not sure what else I can do. Thanks in advance!

I know there is a way to change the settings to force all pop-up windows to open as tabs, but is there a way to change this setting for a particular link that opens as a pop-up? Basically, does Firefox have an option similar to the "show as tab" right-click option in Chrome for pop-up windows?

i had 2 versions of firefox on my desktop, so i deleted the older version....wrong. it was the one that had all of my bookmarks, themes, and plugins, so i had to start all over. i got most of them back on but now when i get to my browser with my customized theme, the whole top is solid even though the screenshot of the theme i downloaded shows the address space and search space to be white. the tabs lines are also hard to see. if i remember right from quite a while ago, i had to change something in about:config to get the address bar and search bar to be white and for the tabs to be a different color than the rest of the toolbar. i'm using 76.0.1 (64 bit). see screenshot below

I've just switched to Firefox from Chrome and need to change some of the hotkeys to a more familiar setup.

Also, another annoying thing I noticed, `cmd+b` opens up the Bookmarks sidebar, rather than bolden the text on a WYSIWYG editor on websites (i've installed FF v76.0.1 (64-bit) on MacOS).

I use AOL for email (comes with Frontier). When I reply to email, the first few characters are in a larger font, then it reverts to the size I have chosen in my set up. Some times it's just 2-5 characters, sometimes it's almost a whole sentence. I've checked with Lenovo help and AOL help and they haven't been able to fix it. I tried another browser (edge) and the problem didn't occur. This makes me think it may be a Firefox issue. How do I fix it?

Hello I have problems with my mozilla.cfg and autoconfig.js it looks like the .cfg does not work if i login with another windows user path: mozilla.cfg: C:\Program Files\Mozilla Firefox path: autoconfig.js : C:\Program Files\Mozilla Firefox\defaults\pref

what is wrong ?

Thanks

I like Firefox, it's a nice browser and I use it because of the browser policy on privacy and because I like to UI, Firefox decided to make the default search engine Yahoo, (I really don't like how Yahoo finds Searches, and its ads) I shouldn't care much because I can just change the search engine in options, except I can't, I change the default to google, but when I search something it still brings up Yahoo. This is annoying but maybe I could live it by just directly going to google to search stuff, except that doesn't even work when I go to google directly! I am just going to assume this is a bug, but if this is intentional, I don't think I have seen something so petty, so horrible as this to force people to use a search engine they don't want to. I don't like any other browsers other then Firefox but I also don't want to use Yahoo so if there isn't a solution, I guess I will stop using Firefox which is sad because I really like Firefox, but I can't support it if its blocking a search engine I want to use. If there is a solution to this please tell. Thanks!

On my Mac I am using a Logitech mouse. Nothing fancy. But uniquely in Firefox (68.6.1esr (64-bit)) the thumb buttons don't cause the browser to navigate forward and back through this history, instead it brings up some odd scroll feature to scroll up and down through the page. The navigation function works correctly in Chrome and Safari so this is uniquely an issue with Firefox. Since it is my preferred browser I would like to figure out where to alter this behaviour.

Thanks!

How do I scroll to bottom and scroll to top INSTANTLY. I hate the fast scroll effect that is very jerky at times depending on the website when scrolling to the top and bottom of a page. I either use the Home and End keys on my keyboard or a mouse gestures addon. I would like this to occur instantly. Thanks. FF 76 with Win7x64. Thanks so much.

Is there a fix in Firefox for this

when using google docs in Mozilla Firefox, my default broser, the right click paste does not work - Firefox requires Ctl. V instead

Thanks Mark

Whenever I open a new window, it starts in a certain standard size (at least in Firefox 77). In earlier versions it would always open "maximised". So for me this behaviour changed (not sure exactly in which version it changed). Since I use my browser almost always with maximised windows, I have to maximise manually all the time now, and that is inconvenient. How can I get the old behaviour back? Preferably I would be able to establish a size I like (maximised, or otherwise as big a size as I set), and then save those settings for the future. Alternatively, I would also be happy if Firefox remembers the size of the window I closed latest. Is there any way to accomplish this?

In the good old days of Dial-up/Serial Comms links, and even today with Telnet, it's possible to get the Terminal to send periodic "no-ops" to the far end to keep the session open/ stop it from timing out with extended gaps between activity. Is it possible to get Firefox to do this too please? I wounder if it's possible to send some form of periodic auto-mouseclick in a set area of the webpage? I'm not looking to circumvent lack of activity session termination entirely as I only want to arrange a slightly prolong the gap.

Hello, In Ubuntu 20.04 (Firefox 76), there is this strange bug. Whenever I reboot/shutdown and start my computer, and after login when I open Firefox (after bootup), the previous session (i.e. the session which was present at the time of reboot) will be opened at the same ubuntu workspace location.

Eg. I had 3 tabs opened in workspace 2 and I shutdown my system. Then I again boot into Ubuntu and open firefox (in the default workspace aka workspace 1), the browser will resume its previous state i.e. it will open in the workspace 2 with the 3 tabs open. So this is like a state restore.

I have disabled Restore Previous Session in the "Startup" section of preferences.

Whenever I play any video in firefox (version 75.0, 64 bit) the video is muted for the first two seconds. Then the sound comes back, and I have to rewind to listen to see what I missed. I'm not sure when exactly this started, but I think it was like this for about a month. Maybe two. I searched for the solution in DuckDuckGo, but couldn't find anything. I did turn off fade-in and fade-out effects but that did not help.

I feel it is some kind of option to avoid sudden audio pop-ins or something. But so far I couldn't find anything relevant in about:config or the browser options.

I'm trying to remove an "add-on" ... iTube but Firefox never takes me to the list of add-ons

When I click on Add-Ons ... it doesn't take me anyway I'm using the latest Firefox 76.0.1

Why Firefox blocking videolist on youtube when I using old design for youtube? http://joxi.ru/Vrw98NOi80O6j2 - old design for youtube: no videolist, http://joxi.net/n2YVavDtZDoxxA - new design for youtube: got videolist. I tested different add-ons and browsers with old design for youtube and only in Firefox got same problem for all add-ons classic youtube design : videolist are blocking in the old design for youtube. Firefox must stop blocking videolist and anything else for add-ons which make old design for youtube!
