Firefox Support Forum

I was quite unhappy with the new Firefox Proton design, so I made a CSS file and copied the following code from a website. However, I don't know what to do to (1) slightly reduce the tab height, (2) get back tab borders for inactive tabs and (3) remove the small gaps between tabs. How exactly do I have to change the following code to do so (ideally, for convenience, please just complete the code accordingly)? Thanks in advance for any support!

/*** Tighten up drop-down/context/popup menu spacing (8 Sep 2021) ***/

menupopup:not(.in-menulist) > menuitem, 
menupopup:not(.in-menulist) > menu {
  padding-block: 2px !important; /* reduce to 3px, 2px, 1px or 0px as needed */ 
  min-height: unset !important; /* v92.0 - for padding below 4px */
}
:root {
  --arrowpanel-menuitem-padding: 4px 8px !important;
}

/*** Proton Tabs Tweaks ***/

/* Adjust tab corner shape, optionally remove space below tabs */

#tabbrowser-tabs {
    --user-tab-rounding: 6px;
}

.tab-background {
    border-radius: var(--user-tab-rounding) var(--user-tab-rounding) 0px 0px !important;
    margin-block: 1px 0 !important;
}
#scrollbutton-up, #scrollbutton-down { /* 6/10/2021 */
    border-top-width: 1px !important;
    border-bottom-width: 0 !important;
}
/* Container color bar visibility */
.tabbrowser-tab[usercontextid] > .tab-stack > .tab-background > .tab-context-line {
    margin: 0px max(calc(var(--user-tab-rounding) - 3px), 0px) !important;
}

I'm asking this question on a different browser because Firefox cant load any websites.

Basically whenever i open a new tab, it opens to a crashed tab. Gah. It cant even load google, or any website for that matter, not even the homepage for Firefox, its just a blank page with nothing on it, whenever i type something into the address bar and press enter it just disappears and does nothing. Browser settings work, but stuff like passwords dont, and i have most of my important passwords on firefox, so i cant log into runescape and stuff.

Can you help?

When watching something on Youtube and I click on the coloured download icon, I get to be able to click on the title of the video. A blue 1 appears in the download icon. When I click again, then click on the blue 1 to watch the download. Nothing happens. The window just sits there and states 'downloading', but it does not happen. This happened last year and you managed to fix it; now Youtube seem to have blocked downloading again. Geoffrey D Dean, Australia.

As I belong to no organization, I find this disturbing. Some of the settings being "managed" for me are not as I want them. How do I get access to them? FWIW. I am using Firefox in Linux Mint. Thank you for your help.

Good day,

Really happy to see that mozilla is tightening up security. But unfortunately, I can't enroll into Two-Step Authentication everytime I enter code it's not being accepted. I tried multiple android apps of those codes and non of them work for me.

Because of that, I lost access to addons.mozilla.com account, because system doesn't let me in without 2step auth enabled.

Any chance I can use yubikey's intead of those auth apps? or anything else I can do?

Greetings... I would like to increase the font size in right click menu box in FF 89.0 (64-bit) (see attached png)

I found a similar 2018 query here at: https://support.mozilla.org/en-US/questions/1241117#answer-1174375

and based on that exchange I added the following to userChrome.css file

/* FONT SIZE IN RIGHT CLICK MENU BOXES 5/1/22 */

1. mainPopupSet menuitem,
2. mainPopupSet menu { font-size: 16pt !important; }

/* */

I closed and reopened FF. This change has no effect on the menu font no matter what font-size value I enter. Have I done something wrong?

tried to import logins etc from waterfox, but pull down list does NOT include waterfox, many others tho, so how can this be done without having to jump thru too many hoops

Today I tried to place an online order to pickup from Texas Roadhouse, but no matter what time I chose a message said it was not available. The only selection that worked was "Earliest Available Time". Finally I called to place an order. Firefox worked 2 months ago but I don't recall which version I was using at the time.

Today I was using FF vers 97.x and later updated to vers 99.0.1 figuring that might be the problem, but it made no difference.

Later I tried Windows 10 Edge & that worked. Then tried a Chromebook & that also worked.

I've also had problems going to the Tracfone website & so have several other people. It's hit or miss with Firefox & usually it doesn't work. But Chrome or Edge seem to work for everyone.

Is this a website problem or a FF problem?

When I login to URL

 https://www.ohiogasprices.com/index.aspx?mss=286965  

with Firefox there is a long delay (~5min.). This happens with multiple machines and locations (w/ Windows 10p and Windows 11p). This started a few weeks ago, I'm wondering if an update is to blame.

It all works fine with Microsoft Edge.

I understand the necessity of some Extensions / add-ons to "Access your data for all websites" and therefore i agree to that for some of them. So here's the question: Is it possible for the data collected by that ADDON to be transmitted over the internet to either the ADDON maker or any other unknown recipient? Or is it that they indeed are collected but stored and processed locally on my computer and never transmitted elsewhere?

I'm using Firefox 104.0.2 (64 bit) under Windows 11.

Under Settings I have selected Startup Open Previous Windows and Tabs.

I normally have more than a dozen tabs.

For the past few days, when I start Firefox my previous session is not restored and I just get the single Firefox tab.

When I got to History there is no longer a Restore Previous Session option.

How do I get it back?

Thanks

Firefox seems to crash repeatedly and generates no crash reports, just freezes up my pc. It works in troubleshooting mode but even after refreshing, the problem persists. Surprisingly, it will consistently crash if I go to `about:support` (except in troubleshooting mode). Any help would be appreciated!

Just updated to the latest firefox version 119, and noticed that the url links are now all underlined again. Checked the support page that says it can be undone in settings, but when I opened up to the said setting page, there's no option to uncheck underline links. Where else can underline links be disabled?

Hey there, I'm having trouble with Firefox. Something inside Firefox is eating up my RAM and CPU. Usually I recognize the problem happening because my laptop fans ramp up. The problem occurs on my laptop as well on my desktop (both on latest stable Firefox[Build ID: 20220513165813] and Windows 11). The workaround is to kill the Firefox subprocess which is using most of the CPU and RAM. Then everything is back to normal for some time, until Firefox starts messing with me again.

While trying to pinpoint the problem I'm stuck. I can't find a culprit other than the fact it has something to do with Firefox. Clean reinstalling did not help. The Firefox Task Manager doesn't know anything about huge amounts of RAM being taken. I searched for solutions on the net and the about:memory indicates the problem is some IPC related stuff:

 {
  "process": "Main Process (pid 12648)",
  "path": "queued-ipc-messages/content-parent(Browser, pid=9612, open channel, 0x22e4b33fc30, refcnt=38)",
  "kind": 2,
  "units": 1,
  "amount": 0,
  "description": "The number of unset IPC messages held in this ContentParent's channel.  A large value here might indicate that we're leaking messages.  Similarly, a ContentParent object for a process that's no longer running could indicate that we're leaking ContentParents."
 }

The bug reporting guidelines(https://bugzilla.mozilla.org/page.cgi?id=bug-writing.html) are encouraging me to attach steps to reproduce and try the steps listed on https://support.mozilla.org/en-US/kb/firefox-uses-too-much-memory-or-cpu-resources . But I've exhausted the steps there (Except for upgrading the PC / RAM).

Especially on the go this Firefox-RAM-Party takes quite some battery and right now while writing this Firefox has >100GB virtual RAM reserved for some IPC messages, I personally think this is too much. So I'd like to file a report, but without steps to reproduce I'm afraid the developers are going to say 'well, that's something we are not able to diagnose', because I am unable to explain how to reproduce it. It just happens from time to time.

The anonymized about:memory report: https://bin.disroot.org/?2ba01ef78154cce4#8PLVqLTd9qgaRn2QVX2P17hkbHQyrTDuVAwoykj2cBxg

I left Firefox running like this for about half an hour and at 138GB reserved RAM Windows slaughtered my Firefox. The resulting crash report: https://bin.disroot.org/?0bc57492585dde4b#5YtbWgXcbZSkWYmg2CGkVn9iiipYwfYbxUfCLhmMJh7d

Do you have a clue where I might find out who sends those IPC messages, and therefore who is responsible for this?

I've tried deleting all history, cache settings. Deleting and reinstalling Firefox. Backing up existing profiles and restarting. NOTHING except starting in Troubleshoot (Safe) mode makes a difference:
