Firefox Support Forum

This has been going on for at least 6 months. When I close my computer with firefox running, when I open it again, I have to force quit it firefox. It says it is open, but I can't see the actual windows. After a force quit, When I try to open firefox again, it says that another copy is already running. There is no fix to this unless I restart my computer. Sometimes it locks the comp and I have to do a hard restart. This is a daily occurrence and I'm getting to the point where after so many years, I will have to discontinue using firefox unless I get some help. mac ios 10.13.6 firefox 91 Thanks!

我用了11年的火狐浏览器，每次重装系统，第一个装的就是火狐浏览器，然后设为默认浏览器，把系统自带的浏览器打入冷宫； 11年的书签，11年的拓展，11年的积极推荐，在今年一次重置密码之后，荡然无存... 如果在我第一次重置密码的时候，知道重置会导致这些内容丢失，我会早就放弃使用火狐。 为什么以前重置密码没有发生丢失，为什么要在重置密码的时候告知用户“可能会丢失”，丢就是丢，可能是什么意思，不稳定？ 用户心理角度来想，一个不去维护书签和组件的人， 对于浏览器品牌来说，就是一个不稳定的用户。所以对他来说，重置密码会影响书签和拓展丢失并没有什么意义；而一个善于维护标签的用户，必然是这个浏览器的忠实粉丝，而你们就是这么对这批用户的？ ———————————————————————— 我不知道你们还有没有以前的日志，还能能不能找到我以前的书签和拓展记录，如果有，看在11年的粉丝份上，可以帮我找回吗？

It's not working, and I can't decide wether I want to search with Google oder DuckDuckGo for example, see screenshot. It only works again after I clear some stuff (see screenshot) through a third party app. (session means "Sitzung", website settings means "Website-Einstellungen")

then it works. Until I open Firefoy another time.

What might have caused it (these are just things that cross my mind, sth else might also cause it):

1. I did some configuration stuff according to a webite in order to see a black page when a website is loading (since I use dark mode everywhere). That didn't work for me so I set it all back to default.
2. I wanted to a add a custom search engine (I think it was Google Images) through the addon "Add custom search engine" and it didn't work.

I deactivate the addon, but the problem still remained, so I activated the addon back again. Greetings from Germany

P.S.: I will put a two more screenshot just for the sake of completeness.

I'm not necessarily looking for a solution, but curious if others are seeing similar issues!

A couple years ago I switched from Google Chrome to Firefox because Chrome was a notorious memory hog and kept making my Macbook freak out (i.e., hang, crash, fan acceleration). But after I upgraded to Big Sur 11.5 a few weeks ago, my Macbook started freaking out again, even with Firefox. Here are some things I suspect are causes:

• AdBlocker Ultimate add-on. Every now and then my fan would go nuts, the add-on extensions in the upper right of my browser would glitch, and Firefox would hang (tabs refuse to load, etc) for about 30 seconds. Once I turned it off my computer has been just fine.
• Dark Reader add-on. Same phenotype as AdBlocker.
• My caps lock key?? This one is super weird. I noticed that when I had the above two add-ons enabled, hitting my caps lock key would commence computer freak-outs.

Anyone else seeing this? If so, what are add-ons you'd recommend that function similarly to AdBlocker and Dark Reader?

I'd like to use Firefox Sync/Firefox Accounts, but without two/multi-factor/step authentication support for hardware security keys/tokens like Webauthn/U2F/FIDO2 and/or even Yubikeys and such, I can't justify the risks.

Is there a way to privately host and utilize these services on private/self-managed infrastructure, rather than using/relying on the default Accounts/Sync servers/services provided by Mozilla?

Cheers

When I download some files from onedrive on the website, my Intel MacBook Pro Activity Monitor shows windowserver high cup usage about 170% and the fan went crazy. But it won't appear on Safari with the same process.

Is this just me? How could I fix it?

Hey all, recently decided to check out whether Firefox will run a bit more smoothly on an aging MacBook of mine then the Opera Beta I still had installed, but I found myself unable to import settings and data from Opera, which is strange as I have been able to import from other Chromium browsers before. The only option the Import Wizard gives me is to import from Safari. I have been able to find what I presume are the files where history, passwords, etc.. are stored on both Opera and Firefox, but I'm guessing they are a different format and I can't just replace them. Anyone able to help here?

Information that might be useful: MacBook air 2015 early running the 12.0 Beta (21A5294g) Firefox version 91.0 Opera Beta version 78.0.4093.103 (both browsers are at their newest respective version)

Thanks in advance!

The network tab in the inspector/developer tools no longer appears to show all the connections. Explicitly it appears to not show initial redirects and errors - which are often the most important part of using it for debugging.

Hello everyone. Almost a month ago I transitioned from Windows laptop to MacBook and since then I have a problem with YouTube videos playback – they very choppy (especially 1080p / 720 @ 60fps).

I tried to test this in other browsers, such as Opera, Chrome, Safari and in this browsers everything plays smoothly with same quality settings on same videos but with no freezes at all.

Can anyone help me with this, please? I don't want to move from Mozilla, I'm using Firefox for years and I'm loving it since my first interaction with this browser, but this problem is just killing me.

If anyone have a solution I will be very grateful.

P.S. Disabling add-ons or reinstalling browser doesn't help, I've already tried. Many times.

P.S.S. English is not my native, but I hope you got my point

Can a picture-in-picture be moved to a second HDMI display on a Mac Mini running MacOS 11.5.1?

Are there keyboard controls to make the video on the second HDMI display fill the entire screen/display?

Thanks.

my aol email has suddenly turned from english to german and I have not been able to change it back to english, my firefox preferences are in english, AOL tells me it is a firefox problem and they can not help and Apple tech has also failed to help. Please advise if possible. deep thanks.

As with the whole planet who uses this browser, unless you're a proliferate IT savant, I can't find my old profile. I renamed it long ago as my primary profile and have updated firefox many times since. On Sat I updated Sahara and my profile won't reload, instead I'm getting a window claiming the profile is too old. I've been through and through the FAQs and am not enough of a successful user to get to the right folder to find a usable profile with my data still in tact. about:profiles, where I usually go now had 43 profiles in it including my previously renamed profile but that doesn't help. I refreshed ff without success. I tried to find help in the waaayyy too many profiles help pages that said click on this, copy this, click on the profile tab, go up one level and turn left and you lost me. Does it have to be so complicated? Where's my usable profile and simply how do I re-initiate it? Thanks.

Some sites do not display. Slowness and crashes

Current version 91.0.1 64bit

This is my default browser and can't access some of my bookmark. I cleared caches, history and cookies

Please advise.

Title: "Using Bookmark Search Plus 2 Extension"

How to Question: Once I found the "Bookmarks" and "Bookmark Folders" that I searched for, is there a way to reorganize them afterwards? I'm asking this question, because I would like to start cleaning up this mess of mine. It probably spans about 4 years worth of Bookmarks, so it would turn out to be useful (come in handy) to be able to regroup them as to keep things more tidy.

I'm still a "noob" using this amazing extension, so thanks for the understanding in advance. I uploaded an image to help illustrate what I'm asking.

So as a brief description, I entered the word "Screeps" on Bookmark Search Plus 2 extension in order to perform an extensive search of all my "Bookmark Folders" and "Bookmarks" that are related to that specific search keyword. And now that I found them, I would like to dump them all in a newly created folder, namely, "Screeps Master - 2021". However, I can't seem to drag and drop them on to a new folder location. If this extension doesn't offer this capability, is there another extension that perhaps allows this?

Any tips or suggestions are more than welcome, who knows, perhaps there's an even better solution that I didn't even think of, but which I'm more than open and willing to try out.

Hallo, sometimes when I type something in the address bar to search in google, I get to about:preferences#search and I have no idea how I got there and why not to google.

I use Firefox on MacOS BigSur

Any time I go into fullscreen mode on firefox browser, whether that be youtube, netflix, disney+ etc. I notice that i do not receive my regular notifcations on my laptop. Sometimes I still get the notification sound, but this is rare. I am on a macbook. On other browsers i have used, i have never had this happen. Is there any way to enable me seeing these notifications, or am I just going to have to watch things out of fullscreen?

I purchased a new Mac about one month ago. I downloaded Firefox and signed in, only to find that none of my bookmarks were there anymore.

In the past, when I have purchased new computers, I have not needed to transfer or save my bookmarks, they've just automatically appeared on the new machine when I download the browser.

I've tried looking for old profile data and I've tried the "restore bookmarks" option, neither of them contain any data whatsoever.

Have my bookmarks disappeared or is there a way to find them?

Since I have the Tree Style Tab extension, I put this code in my userChrome.css to remove the tab strip on the top: ```

/* Hide tab strip but keep space for window buttons */
#main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar > .toolbar-items {
    opacity: 0;
    pointer-events: none;
}
#main-window:not([tabsintitlebar="true"]) #TabsToolbar {
    visibility: collapse !important;
}
.tab {
    margin-left: 1px;
    margin-right: 1px;
}
:root {
    --tab-toolbar-navbar-overlap: 0px !important; /* fix for full screen mode */
    --tab-min-height: 25px !important;
}
:root #tabbrowser-tabs {
    --tab-min-height: 25px !important;
}
#TabsToolbar {
    height: var(--tab-min-height) !important;
}
@media (prefers-color-scheme: dark) {
    #TabsToolbar {
        background-color: #2B2A33 !important;
    }
}
@media (prefers-color-scheme: light) {
    #TabsToolbar {
        background-color: #F9F9FB !important;
    }
}
#TabsToolbar[inFullscreen="true"] { /* Do not display window buttons space in full screen */
    display:none!important;
}

``` Is there any way to make this block of code to only be activated when the sidebar is on Tree Style Tab? Something like the `#TabsToolbar[inFullscreen="true"]`. Because I can't navigate through tabs if the sidebar is on (for example) bookmarks, or switched off.
