Good day everyone,

I have been breaking my head over this for about a week. After the last update that was installed, now my tab width is smaller than the minimum width I have set them to. However, this only happens with active tabs from pages that have an embedded video. At first I thought this was just a thing with YouTube, but it seems it also happens with other video sites. I guess it may be related to whenever the playback button displays in the tab title and it detects there is video content.

I would like to know how to fix this behavior so that my tabs are no longer shortened beyond the minimum width setting.

Thank you in advance.

Hi. There is a new feature of Firefox that bothers me. It is when I drag tabs around the top, they try to group when I don't want them to. So I go to about:config and find the "browser.tabs.groups.enabled" key and set it to false. But when I restart Firefox, the change reverts. How do I fix this so the change stays?

I've already tried going to Menu->Help->More troubleshooting information->Profile Folder->Open folder, but there is no "user.js" file there. Do I have to do a Firefox reset to fix this? I hope not...

Note that I'm pretty sure that other settings that I change do not revert when I restart Firefox. Right now, it seems to be just this one about:config setting, unless the new version of Firefox reverts all manually changed about:config settings upon restart.

Thanx in advance for any help.

a website im using is trin to call an api with referer header and policy of "origin-when-cross-origin", but firefox overides it to "Same Origin Policy" with console msg: Referrer Policy: Less restricted policies, including ‘no-referrer-when-downgrade’, ‘origin-when-cross-origin’ and ‘unsafe-url’, will be ignored soon for the cross-site request

After a lot of search, i found that network.http.referer.disallowCrossSiteRelaxingDefault config setting should be set to false to allow any policy, but toggling between false or true has no affect. The request still fails with a cors error "Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at..."

Is there a way to make this work? Or a way to allow the request to have this referer policy.

Firefox Cache Management and New Tab Behavior Improvement Request

Hi all,

I’ve been using Firefox for a while now, but coming from Chrome, I’m finding some aspects of Firefox’s cache management and tab behavior a bit inconvenient, and I wanted to share my thoughts.

The issue:

When I restart Firefox (version 133.0.3-1), it loads webpages from the disk cache, which is fine because I’ve set browser.cache.disk.enable to true and browser.cache.check_doc_frequency to 2, it will always make a request to the server on restarting Firefox with the default value of 3. However, the problem arises when I open new tabs — they also load from the disk cache instead of requesting fresh content from the server.

What I’m looking for:

   A way to have Firefox:

Load webpages from the disk cache when restarting the browser (which I want, and I have set browser.cache.disk.enable to true for this). But always make fresh requests from the server when opening new tabs, no matter what the cache settings are.

In Chrome, this behavior is more intuitive — it loads from the cache after restart but always fetches from the server for new tabs, which I find to be much more reasonable.

I understand that about:config provides settings like browser.sessionstore.restore_on_demand, but adjusting this option makes Firefox fetch content from the server for all tabs, including those opened after a restart. This doesn’t seem like a perfect solution because it takes away the ability to use the disk cache after restarting the browser.

I would really appreciate it if Firefox could offer more granular control over this behavior, so users could get the benefits of both caching and real-time requests based on the type of tab (restart vs. new tab).

Thanks for your attention, and I hope to see some improvements in future updates!

Hello,

I have been experiencing this issue for a while, but only just now noticed it. When I hover over a tab, nothing shows up; no preview, no title, no web address, nothing. I have a few extensions, but uninstalled any that would effect tabs at all, with no change. All other extensions I have had since I switched over to Firefox. I have attempted to search for solutions, and have followed what I found. Multiple support questions here have gotten the answer of going into the config to change the following Boolean variables to be true:

   browser.tabs.hoverPreview.enabled 
   browser.tabs.hoverPreview.showThumbnails 

but when I went to do so, they were both already set to true. I disabled and then re-enabled them just to check, but nothing changed. I have a ridiculous amount of tabs open, but that's the only other thing I can think of that would be causing this issue. Just in case, I am in the process of closing as many as I can.

Any advice or assistance would be appreciated.

Thank you.

When accessing about:logins, Firefox prompts for system authentication (Primary password or master password). However, if the user cancels the prompt twice, the password manager still opens and displays all saved logins without authentication.

This behavior bypasses the intended security check and could pose a risk, especially in shared or public machines

I had the same problem as, for example, this:

 https://support.mozilla.org/en-US/questions/1375244

firefox (on linux) was unable to open a file browser to the local filesystem on clicking a website-provided button for file uploads, e.g. here https://video-converter.com/

I have seriously messed up with firefox settings over the years in order to safeguard my privacy, against all the attempts by firefox to infringe it. (Admitteddly, not as much as google chrome, safari and, got forbid, m$ edge). One of these fixes was to link the file/database content-prefs.sqlite (found in my firefox profile dir) to /dev/null. It was this that caused a problem with the file browser not showing. WOW!

Once I deleted said file (linking to /dev/null). Firefox started and all was OK wrt the file brower.

That caused me to create a script to be run before and after firefox launch, searching for all these privacy-infringing databases in my profile dir and erasing them.

The steps to this are: 1) edit /usr/share/applications/org.mozilla.firefox.desktop and replace all Exec=firefox entries with Exec=/usr/local/bin/firefox-custom.sh 2) create a new file /usr/local/bin/firefox-custom.sh with this content

  1. !/bin/bash

CMD="firefox" if [ -x ~/bin/firefox-custom.sh ]; then CMD=~/bin/firefox-custom.sh fi echo "$0 : executing firefox with this command :" echo " ${CMD} $*" ${CMD} $*

3) create a ~/bin/firefox-custom.sh file with this content

  1. !/bin/bash

function eras { local f="$1" echo "erasing file '$f' ..." rm -f "${f}" }

echo "$0 : on starting, erasing various sensitive firefox databases ..."

while IFS= read -r afil && -n "$afil" ; do eras "${afil}" done <<< "$(find ~/.mozilla/firefox -type f -name 'content-prefs.sqlite')"

echo "$0 : now executing firefox ..." firefox $*

echo "$0 : on exiting, erasing various sensitive firefox databases ..." while IFS= read -r afil && -n "$afil" ; do eras "${afil}" done <<< "$(find ~/.mozilla/firefox -type f -name 'content-prefs.sqlite')"

lanuching firefox now either from a desktop file (e.g. via Plank launcher) or from the command line: gio launch /usr/share/applications/org.mozilla.firefox.desktop runs the above script before and after firefox running.

Disclaimer: the above script erases files in your profile directory, use at your own risk. Perpahs make a backup copy of your profile dir before.

Why is there in about:config no reference to documentation of the displayed settings?

e.g. browser.chrome.toolbar_tips.hide_on_keydown

What is it? What is the meaning of the values? What is the default value? Why do we have to guess?

It is probably documented somewhere (I hope). Why is there no reference to it in about:config?

Hello Since few weeks (maybe on firefox 132 already, but surely on firefox 133) I observe issue with my firefox UI. While grabbing and holding tab (to change its position, move it on bar), whole tab bar gets thinner which realigns my whole UI. Issue is probably caused by my custom userchrome.css but I need it in current or similar form. Maybe there is some css specialist who can help me remove unnecessary parts of code?

My css is as follows:

.tab-background{ border-radius: 0px 0px !important; margin-bottom: 0px !important; } .tabbrowser-tab:not([selected=true]):not([multiselected=true]) .tab-background{ background-color: color-mix(in srgb, currentColor 4%, transparent); } menupopup > menu, menupopup > menuitem{ padding-block: 3px !important; min-height: 0px !important; }

root{

--arrowpanel-menuitem-padding: 2px !important; }

Recently in our workplace, we had several computers that suddenly stopped being able to access several websites, the issue started shortly after pushing a updated Firefox across the floor.

I tracked the issue down to being related to security.tls.version.fallback-limit defaulting to 4, instead of the old 3.

Setting the value to 3 resolves the website accessibility issue.

A.) How can I confirm if this is a recent change or not? Everything I read seems to indicate the default should already be 3, but its very definitively not.

B.) What is the best way to push a pref adjustment change across the floor if the option isn't present in the registry and isn't a GPO option? Is my only option really to make some script that scans every computer's users folder, check every user folder's appdata\mozilla, scan every profile for a pref.js file, and do a string search for a reference line and then do a line addition if a certain string doesn't exist?

I can do this, it just doesn't seem like a good long term fix as I would have to run this script regularly as users come and go....

I am on FF 128.7.0esr (64-bit) under a new profile.

Changing Default Behavior (CSS)

When I'm reading on a computer screen, I hatehatehatedespisehatehatehate "widow and orphan" control. This is especially annoying when reading a long narrative passage that reflows so that a break (often a blank paragraph) falls at the bottom or top of a column/page. There are two relevant CSS properties, each taking a nonzero positive integer as an argument:

    widows: [number of lines]
    orphans: [number of lines]

It appears that Firefox has (like most browsers) established a "default" value of 2 in each of these parameters, which seldom appear in site-specific stylesheets. Do Not Want.

Is there a way to change this default behavior to the equivalent of:

    body {
         widows: 1;
         orphans: 1;}

without either (a) breaking anything or (b) having to redo whatever change every time there's a Firefox update?
