Firefox Support Forum

It's so frustrating that the keyboard shortcut for closing tabs is right beside the one to quit Firefox. I've lost countless hours because of this, and it's so easy to accidentally do. Is there a way to keep this from happening? A simple "Are you sure" confirmation dialog would be great, or I really like the Chrome "hold command-Q" to exit feature. This seemingly simple function is proving extremely difficult to accomplish.

Yes, I'm aware of session restore, but (1) It does not preserve my window arrangement. I use multiple desktops for various tasks, and they each have related browser windows. (2) I need to see webpages exactly as they were when I opened them. Sessions expire, dynamic pages are refreshed, content is removed etc. That is all lost.

I do not want to disable session restore completely. It can still be useful. But, I do not want to trigger session restore automatically every time. Manual activation is ideal.

regarding: "browser.tabs.warnOnClose" I do not want a warning for closing multiple tabs. I often have many windows open and that warning gets annoying. It also doesn't prevent me from accidentally quitting when I only have one tab open.

I tried setting browser.warnOnQuit to true, but it's ignored.

I simply want a confirmation when I use the keyboard shortcut to QUIT. That's it. No side effects. Can Firefox do this?

Since the last (?) update, sometime in the spring months this year, Firefox has not been able to display website fonts correctly. Often times part of the fonts turn to question marks, and the problem just turned even worse: even sites that I use regulary turned to complete mess – ALL TEXT. What the hell is wrong?

And NO, preference settings have no effect whatsoever.

The latest version 84.0.1 for Mac now opens a new print menu, which is terrible. How do I force it to go away and permanently default to "print using the system dialog", which "Firefox help" never heard of. I can't find any way to get rid of it. It is a hateful change to Firefox, I hate it and my sister is in tears. She hates computers anyway. Seniors can't handle these dramatic changes.

Wow... I just updated and am trying to use Firefox as my default browser yet again, however, yet again, it's RAM usage is ruining an otherwise good relationship. Why does this browser guzzle RAM so hungrily? I had to reboot it as I couldn't type any longer, without waiting every few letters before seeing them on the screen, and I've got 60 Gigs of RAM. But Firefox was using 22 of them!

This has obviously been an ongoing issue for years, both from my experience, and the 2,000 threads that come up in response to this issue. Come on guys, it can't be this impossible to create a functional browser that is more RAM efficient, what's the problem?

Oh, and it sure would be nice, given 2,000 results from my search, to be able to filter them by date. I'm using version 84, so threads dealing with version 50 or so, aren't going to be of much help...

Cannot display my history in my sidebar. Receive this message:

Cannot find a way to fix.

In MacOS Big Sur 11.1 on my MacBook, I have set MacOS to automatically switch between Light Mode and Dark Mode. But I notice that Firefox does not handle this well. When I have used my MacBook Dark Mode and switch back to Light Mode, Firefox still hangs in Dark Mode. The only way to solve this is to choose Light Mode in System Preferences instead of automatic.

Hello,

My Firefox routinely shuts down while I'm using my 2018 Macbook Pro, and the problem began when I updated my IOS to Big Sur This is a systemic problem with non-native apps ever since installing Big Sur. Apple won't address the problem unless I confirm that my non-native apps are compatible with Big Sur. Can you please confirm the most updated version of the Firefox Browser is compatible with Apple's Big Sur IOS? Can you also let me know if other users have experienced problems and if there is any fix?

So I've disabled Firefox updates because of the personal preferences. It keeps nagging me every day with the modal to update. How do I disable this annoying useless feature?

Firefox 85.0 on mac os.

I've tried searching "about:config" for all preferences that contain "update" and look like timers and changed the timestamps to something in the far future. Still no dice, the update dialog keeps appearing every day like clockwork.

When I record screencasts, I don't want people to see what extensions I'm using. For one, it's distracting, for second, it's a privacy issue.

In chrome (iron, opera...) I can quickly drag and resize the extensions area so nothing is seen. Fast an easy.

Is there a way to do this in Firefox. I am open to extensions or keyboard shortcuts as well!

(Pinning to overflow menu is not a solution. It takes many clicks and a long time.)

Thank you for any help.

Hello, is there a way to turn off the new print function. I want my print program to open and not a complicated print program that cannot be used by us. Since this new setting, we can no longer print properly and have to do all print jobs with a screen print.

I'm running Mojave 10.14.6 on a MacMini (late 2018) with 64 GB 2667 MHz DDR4 and Firefox v86.0 64-bit.

I need to disable Command+D that's currently used to "Bookmark This Page".

I need Command+D for another use.

I've searched about:config for "bookmark" and get a lot of hits, but I can't tell which one controls the setting for Command+D.

Or . . . am I barking up the wrong tree?

I want to disable Command+D.

Leaving the ability to mouse up and click Bookmarks > "Bookmark This Page" is ok.

I just need to disable the keyboard shortcut Command+D for "Bookmark This Page".

Anyone got a "howto" for this?

Thanks!

Hi a lot of websites I visit are not displaying the font correctly when using firefox. I have set "Allow Web Sites To Choose Their Own" already in the preferences. See image below for example. It's happening a lot at the moment . I have updated to latest Firefox and Mac OS is latest. Pages are fine when viewed in Chrome. Help please! Cheers- Vince

Firefox alias icon keeps replicating itself in the toolbar at the bottom of screen where all of the alias icons are located. Had a session with an Apple rep which did not work. Used a virus protection app that did not remove the aliases. Any ideas?

I raised the problem and had a response kindly trying to assist but after following all the steps advised I still can't access any bookmarks or history.

I have located the places.sqlite file as advised and renamed it but when I restart Firefox nothing changes and it makes no attempt to recover bookmarks from the backup files.

I would welcome any assistance as I have saved details I need.

Thank you.

The last fully compatible version I could use was 78.6.1 ESR. I know I need a new profile to go backwards but I can't find the specific file. I can see the version I would like in a directory but don't know how to download/install it. Thank you all:)

Have 2011 Mac which won't support newer OS updates.

The option in the Help menu for "submit feedback" is still present on version 87 but is no longer functional and has been out of service for 3 months.

Is an expected date or version pending to reactivate or will it be removed?

When I press Command + D to make a new bookmark, the editor will disappear on its own after a few seconds. How do I make it stick around until I click Done? I'm sure it'll be in about:config, but I have no idea where.

Thanks!
