Hello there,

I like Firefox to ask me what to do each time with PDF documents, so I've set the action for PDF to "Always Ask". However, I've noticed that when I load a page with a PDF document embedded inline, and I select "Open with Firefox" on the dialog box, the document always opens in a new tab.

In other words: there are certain PDF documents that get displayed inline when the action for PDF is "Open in Firefox"; but those same documents get opened in new tabs when set to "Always Ask".

Is possible for Firefox to display PDFs inline while asking me what to do each time?

Thanks in advance!

On linux terminal the text should change color but how do I do that on firefox? By the way I have these settings for the caret ui.caretBlinkTime 0 ui.caretWidth 7 Not being able to see the character under the caret is problematic, would be nice if anyone knows what to do.

When FF loaded for first time after update had message about being able to fill in PDF documents. Even said give it a try on a option block. Then it displayed a form with blanks to enter name etc. However I wasn't able to enter name or data in the fields they sent me for trying it out. I could do other things with PDF FF displayed, draw, add text box, but not enter data on the form they sent to try it out. Wish I had saved the PDF they sent to show the new feature.

I Use Mac OS Firefox as my primary client for Gmail, and I always compose emails in a pop-out window. Ever since Firefox 124, these pop-out windows include the tool bar and bookmarks bar, eating up a bunch of space. I do want those bars displayed on my main firefox window, I don't want them displayed on the pop-up Gmail compose windows. Is there anyway to get Firefox revert back to this old behavior?

For introduction, sorry if My English was very bad.

Suppose I was in YouTube (https://youtube.com) domain name, then from that URL, I went to https://youtube.com/history (that is, all in the same domain name YouTube, but different URL) by clicking the history button. The same I did when I clicked https://chat.openai.com/c/d93ac426-c5d1-451b-abc4-fc82739f..... from https://chat.openai.com/c/d93df...... (went from one chat to another) or to https://chat.openai.com/ (went from current to new chat) by clicking the list of chats at leftmost vertical panel. When I saw the top left corner of Firefox browser, the "round circle arrow" reload button was not change to "X" or any other symbol specified that the page was going to different link (different URL). Previously I have had went to this https://github.com/microsoft/playwright/issues/15781 page, and mostly not specified the problems at all. I went to ChatGPT and it said that "I must change the 'false' to 'true' of browser.tabs.remote.separateContentProcess object/variable in about:config. When I searched for that, it seems I found browser.tabs.remote.separatePrivilegedContentProcess" and I have had toggle this to ensure if YouTube, ChatGPT, or other domain will refresh/reload the page when it went to different URL in the same domain, but nothing happens.

The problem is, this is not happen in Chrome Browser. Because of Firefox is my default browser, multi-functional, configurable, I want to make this behavior can also happens in Firefox rather than Chrome. Is there any solution of this?

Updated to Firefox 124.0.1 on March 28 (from 123.0.1, which was installed on March 12). This update also installed the Keeper password manager addon.

This is a work PC so it's locked down by IT admin, including extensions on FF. I have no access to about:addons ("Blocked Page - Your organisation has blocked access to this page or web site") and it's impossible to install Xpis.

However, extracting info from extension.json shows that Keeper® Password Manager & Digital Vault Version: 16.8.1 was installed at the time the update to FF 124.0.1 happened. See images.

How can this happen? What can be done to remove Keeper, given that I don't have access to about:addons?

Possibly relevant: I do have some extensions that I had installed before Firefox extension access and install was locked down by Admin (lock down of FF was done remotely through some kind of policy), including LastPass.

Hello,

I'm using a PC with windows 11 and my Firefox is up-to-date 124.0.1 (64 bits).

1- It's been several years since a "full screen <=> rest of page" transition was implemented on youtube (using the scroll wheel for example). Is there a way to completely hide YouTube's vertical scrollbar in full screen mode?

I've checked with Opera and Edge browsers and their behaviors are normal in my mind, as the bar is simply hidden in full-screen mode, no matter where I move the cursor. https://ibb.co/nkJzb8S

On Firefox, it is hidden but only if you don't move the mouse or hold the cursor over the scroll bar. https://ibb.co/VW3JTzp Is this an expected behavior in Firefox?

Otherwise, I've tried a couple of "hide scrollbar" style add-ons, but nothing worked, at least for this particular vertical bar, in full screen mode. I also tried the Troubleshoot mode, and to delete the internet cache with no more success. Here's how it looks in pictures (moving ones :) ) to make it clearer https://www.youtube.com/watch?v=UrJa60LHEws

2- Another question please, why are add-ons disabled on mozilla.org pages, and is there a way to enable some of them on there ?

Thanks for your attention and any help you can provide. Damien F.

i made a custom firefox colour setup for my desktop machine, and it doesn't have any option to save it- because of this, on my laptop which is synchronized to my desktop's firefox settings, it is not showing up at all and if i go to firefox colour it isn't there for me to add. so how do i DO this???

i do not want to maker my custom setup public so it is not available to all, it is my own setup using some of my own artwork which i do NOT want made public on the internet.

there MUST be a way to save it however and let my laptop's firefox also display it,m yes???

and on that topic, why isn't it just automatically synchronizing when everything else does?

Hello forum participants,

since some Firefox versions the setting "browser.fixup.alternate.suffix" no longer works. I found that all "browser.fixup.alternate" entries do not work anymore. After searching the web I found an answer that the fixup.alternate options don't work when the protocol is https. So, because today nearly all Websites use https, this options are completely without function. In my case I want to add the default TLD ".de" if I do not enter the TLD. Is there any place (except source code, of course) to configure this behavior for https, too?

Many thanks in advance! Have a nice day

So when I installed an update today all of my extensions and add ons were removed and I have a folder on my desktop that apparently has all their data is there any way to restore that data? Or is it just lost in the update?

I've tried a few addons that download website images but the website I go to has thumbnails that are linked to larger jpg's and addons I've used won't download the linked jpg's. I used "Download all images" addon which has a "Deep Search Option" and filters for downloading linked images but I can't get it to work. I couldn't figure out how to use the filters. I read about another addon called "download-links" that can search linked images and I might give it a try. Any suggestions? Has anyone tried "Download all images" addon?

I'm installing a Docker service set onto a new Ubuntu system, that has Firefox installed by default. One of the services is a GUI application.

However, when opening Firefox for the first time, a dialog shows up that I would like to disable (attached).

How can I disable this?

I'm running Firefox using: "/usr/bin/firefox --kiosk http://localhost"

I've already followed a lot of the suggestions in here: https://searchfox.org/mozilla-release/source/remote/shared/RecommendedPreferences.sys.mjs (and verified they are indeed set after installing my own "user.js" file), but I cannot find an about:config preference that disables what I'm still seeing.

Any help or ideas?

Hello,

We are using a PAC-File. In the Function: FindProxyForURL(url, host) you return the Proxy. We are returning the Value:

How Firefox determ wich Proxy is now active? We see that Firefox often takes the fallback Proxy. Which

Hello, We are using a PAC-File. In the Function: FindProxyForURL(url, host) you return the Proxy. We are returning the Value:

     "PROXY proxy1:3128; proxy2:8080".

We see that Firefox often takes the fallback Proxy. The connection via the Fallback proxy is much slower than the connection via the original proxy. 

My Questions: How does Firefox recognize which Proxy is now active? Is there away to debug the Proxy Selection? Can I give a priority to a Proxy?

In the browser settings I use a color preference that replaces white with black, this works with pages where Dark Reader is not available. These settings are needed so that when surfing the web at night with the dark mode on, my eyes don't hurt from contrasting bright white elements with dark-colored pages. For example, it works on single image pages - in situations where except for the image the rest of the page is colored solid white; It also works for some add-ons - on settings pages and pop-ups.

I'm interested in being able to automate toggling on/off the «Use system colors» checkbox, which is in the browser «Color» settings. It would be great to somehow synchronize the activation of night mode in Dark Reader with disabling checkbox responsible for using system colors. Or, for example, make it so that when the «Website appearance» setting is set to «Automatic», the checkbox is switched accordingly together with it - being disabled when the appearance is dark and enabled when it is light.
