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?

hi,

can someone suggest how i can fix this. I use private browsing window for most things and when PC opens links i need them to be in private mode. But they all are opened in non-private browsing and load browser full of trash cookies even before they receive permission to do so (EU regulation). Causing me to delete these trash cookies every time.

So How can i set to all links from outside Firefox are opened in Firefox private browsing window?, or How can i set that before page loads in Firefox there is pop-up that ask if i need this opened before it is loaded?

When I use firefox on my main display (1920x1080 144h 16:9) in full screen there is a noticeable white line in the bottom, not using full screen fixes it, but a pain in the ass to resize it all the time. I tried using the browser on my secondary smaller display (1920x1080 60h 16:9) and there is no white line. This seems to be a bug, how do i fix it?

Hi,

For a long time, Firefox has been crashing when I try to open the ADS-B website for tracking aircraft.

This problem is intermittent.

ADS-B is a huge aviation safety improvement.

Because tracking of military aircraft is often prevented, I attributed the crashing to a crash signal from military aircraft departing the nearby airport.

There are privacy concerns that have led to a new system for ADS-B.

There is also an unrelated FAA-offered blocking feature for radar tracking which allows aircraft owners to block radar data from being viewed by the general public.

Today I learned that it is impossible to paste anything to the Mozzila Crash Reporter block.

I haven't found a way to see any relevant crash report info in the Activity Monitor feature.

I haven't updated Firefox to the newest yet because the last time I upgraded I found that the appearance of the tab bar had been changed, and it took too long for me to return to the desired previous appearance.

It is often not easy to go back to a previous Firefox edition.

I understand the need to solve problems via upgrades, especially security problems, but now our late 2013 Macbook Pro Retina is stopped at OS 13.6, and perhaps also stopped at Firefox 99.0.1?

Perhaps security fixes will soon be impossible.

Thanks for your consideration.

For example: 1. Certificate "CA.A" is trusted by firefox by default. 2. Certificate "CA.B" is issued by certificate "CA.A", but not stored in firefox by default. 3. Website "WWW.C" use a certificate "CA.C" which is issued by certificate "CA.B" 4. After I visit "WWW.C", firefox will report it is a secure connection and will add "CA.B" to "Certificate Manager".

Now I want to untrust "CA.B" and all certificate issued by it.

In firefox old release(like firefox 45), there is an "Import" option in "Certificate Manager"->"Servers", I can import "CA.B" to untrust the certificate. In firefox new release(like firefox 112), there is no "Import" option in "Certificate Manager"->"Servers", so I can not untrust "CA.B". I have also try to untrust the certificate in "Certificate Manager"->"Authorities"-"Edit Trust", but uncheck the checkbox can't untrust the certificate and firefox still report it is a secure connection when I visit "WWW.C".

Does anyone know any way to force Firefux [Ver 89.0.2 64bit] to stop the repetitious and constantly annoying pop-up that flashes on open, restart, or randomly appears, reminding me to once again update the apparently flawed software. I just updated yesterday!!!! Can I not trust that the programmers know what they're doing and that the system can actually work as expected without the intrusive proof that they screwed up again?! This is the worst business decision to make these things interfere with my workload. Every firefuxn day there's a new update alert!!! It makes me not trust this browser...

Thanks to Proton expanding my Bookmarks Menu off the bottom of the screen, I was re-arranging my bookmarks folders. While wondering which of my folders I had to prune, I noticed another in-built redundancy. The entry "Manage Bookmarks Ctrl+Shift+O" appears twice, at the top and the bottom of the menu. Incidentally the bottom entry is misaligned (Firefox v89 on Windows).

Is there a particular reasons for this duplication? Can I remove either of these entries?

system：win7 x64 version：firefox89 error：Can't decode H.264 stream because its resolution is out of the maximum limitation source ：https://www.bilibili.com/video/BV1qu411d7ot

Watching the video of this website，browser report an error”This error message will be blank when privacy.resistFingerprinting = true.

How can I resolve this error？

Every solution which I have found for Firefox 89 "Proton" so far which moves the Tabs Bar below the Navigation Bar (AKA "address bar"), with the Menu Bar above it, does NOT move the Tabs Bar below the Bookmarks Bar. The Bookmarks Bar appears to be overwritten and blank, and occupies space below the Menu Bar, Navigation Bar, and Tabs Bar. This empty space separates the three bars which are implemented and the content of the currently-selected tab below it.

Currently, my userChrome.css file is a copy posted by Cor-el (?):

Evidently, the text editor for this website does several things to the above original text that, frankly, seem unnecessary and undesirable. The .CSS file is just an unformatted text file, so what is the problem with simply copying its contents and pasting it in to the body of this post?

Which is also to say that I do NOT have a clue as to what any line in the file is meant to do, what effect it has, why it is even in the file at all, or why it is written in the way that it is. So DO NOT tell me that I "CAN" create a Cascading Style Sheet on my own when I cannot even modify one that has been provided.

On the face of it, something is missing from the above CSS text. What change needs to be made to the above content so that the Bookmark Bar will appear between the Navigation Bar and the Tabs Bar??

Thank-you very much for your time and attention to this request for assistance.

Running Firefox 89.0, Win10. I usually bookmark all tabs in a window to a named folder under Bookmarks Menu, for example Folder1, Folder2, Folder3, etc. Recently, the dialog was stuck to a previous folder, lets say Folder2, as the default, instead of the normal default of "Bookmarks Menu". If I bookmark Folder4, it will want to put it under Folder2 as a subfolder, unless I manually change it to Bookmarks Menu, but the next time the default will go back to Folder2. After trying to manually set the default back to Bookmarks Menu, without success, I tried renaming Folder2, thinking the default will go back to Bookmarks Menu. This didn't work, Firefox chose the new Folder2 name automatically. So next I opened all the tabs in Folder2, deleted the Folder2 in the bookmarks manager, thinking that if Firefox couldn't find Folder2, it would fallback to the old default of Bookmarks Menu. Now when I try to bookmark anything, the save dialog is blank and the only thing I can click is the cancel button. How do I fix this? I have hundreds of tabs open, since the session manager I used to use is no longer supported, I was in the process of saving windows into bookmark folders. I'm worried that restarting Firefox will lose some of recent changes to my open windows/tabs state since the last time Firefox "autosaved?" my session

Thanks

I'm currently running V. 89 on a Windows-7 machine. The system runs a GE-Force 700 series video card. I just recently added more RAM to my system (currently 4 GB) and the OS is running all the latest W-7 updates. I want to upgrade to the latest FireFox version (112), but am having problems with it. When I go to run V. 112 on YouTube, there is an annoying hesitation whenever a video is running and I go to move the mouse around the page with the video stopping for 1/4 second and then restarting with each mouse movement. I disabled hardware acceleration, but the problem still won't go away. I don't see it on other sites, just YouTube. It's so annoying that I uninstalled V. 112 and re-installed V. 89. Any suggestions? Thanks.

Firefox updated and now my tabs are above the address bar, I hate it. I have went through all the information I could and created a new chrome folder, downloaded the css and changed user preferences but it sets the tabs to the bottom of the screen not just below the address bar. I think I need a different set of code for the css but cant find a copy. Does anyone know what to do?

In the past, logging in to my Firefox account has caused new installs to just sync with my previous settings, bookmarks etc, but my computer had a... spaz & I had to do a new install of Windows 10, and Firefox will not sync. I've tried hitting 'sync now'...

Hi Team,

While opening Firefox web browser via Geckodriver, and when we open the page: about:preferences

if we scroll down to Firefox update, It will get stuck there for indefinite time in "Checking for updates". Can someone look into this issue.

I need to automate the way by which it checks if it is updated or not. Kindly let me know if there are any other steps to check the same. Though above issue is i feel a bug and that is the reason we are writing you down.

I downloaded Firefox on my Chromebook using the instructions found here: https://support.mozilla.org/en-US/kb/run-firefox-chromeos However, I have not been able to update it since. It says updates are disabled in Firefox itself, and I have not been able to fine what files I need to update via Terminal to get the most current version. (I have been able to update other files through Terminal). Can someone please point me in the direction of how to update Firefox if installed in the manner described in the link?

Hello,

I've just recently been experiencing this problem.

I would play a Youtube video, but after a few minutes, it would just stop, no error message. It just stops.

I then reload the page, but then it plays with no audio. I would have to close Firefox and restart the video, just to have it stop again after a few minutes.

I have the latest version of Firefox installed. I've tried refreshing the Firefox setup, uninstalling and reinstalling, reinstalling the video drivers, but nothing seems to be solving the problem.

Video plays just fine with Chrome or Edge.
