Firefox Community Forum

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.

Hi. I have followed the instructions on the Mozilla site above however this does not work. The Enterprise Roots keep reloading after a while.

Any idea how to stop this happening?

I have read many articles on this but nothing works. The E Roots will in initially not reload but eventually after a day or three its back.

Many thanks

After typing in about:config and clicking on the 3 lines top r.h. corner I'm supposed to get a page that list preferences. (using Wndows 11) That page does not appear. I wish to change my value for width scrollbar width from zero to 4. I have also accessed videos - with sound -but find i very hard to follow the voice of the presenter because he/she talks far too fast, and in many instances is outdated! I need a page on screen that tells me to type in specific keystroke to get to the page that lists a preference I can change.

Hi there,

Is it possible to change the padding of menu items in both the menu bar menus and context menus with userChrome.css?

Please see attached images.

Thanks.

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.

Hello!

I would like to dump Chrome and return to using Firefox. I just would like to know if it's possible somehow to remove about:mozilla page from within a browser (it's important for me). If anyone knows of a way to do it - please let me know.

Thank you!

I have a requirement where instead of showing the 404 error or 503 error on screen, I want to display a blank screen. I have already tried to set the following configs to false -

security.insecure_connection_text.enabled security.insecure_connection_icon.enabled security.insecure_connection_text.pbmode.enabled browser.ssl_override_behavior security.ssl.errorReporting.automatic security.enterprise_roots.enabled security.tls.version.min

Is there anymore steps to do or any userChrome.css script is required.

PS : I cannot use any extension or addon to do that

Steps to reproduce- (1) Enable 'accessibility.blockautorefresh' in 'about:config' (This is said to ask for permission before redirecting) (2) Go here (3) End up here without permission

Extensions I'm using- Privacy Badger, uBlock origin, clearURLs and Show/hide passwords

Another question, does enabling this setting also stop internal redirection?

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!

Steps to recreate:

1. Open any website
2. Make any css changes. These will be shown in the Changes tab in the dev tools
3. Close dev tools, then re-open. Now those changes won't be shown

Sometimes I need to close dev tools in order to see how the web page would look normally.

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.

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?

Hi Firefoxians,

I would really appreciate the help!

Hello,

I have an issue where, when I switch tabs with Ctrl+Tab, my mouse cursor accidentally triggers something if it happens to be in the center. This is very annoying. I tried Googling how to turn off tab visualization through the config, but it hasn't worked so far.

   * browser.ctrlTab.previews

• browser.tabs.closeWindowWithLastTab
• browser.tabs.animate
• toolkit.cosmeticAnimations.enabled

So now, the only option I see is to turn off Recent Tabs, but then the browser becomes unusable. I also tried the same on a new clean user profile and even on new Mozilla-based browsers, but still nothing. It would be ideal to make the cursor inactive while switching tabs, like it is in Arc Browser and probably many others. But I would be happy enough to just turn off tab switching visualization.
