Firefox Support Forum

I recently updated to 125.0.1 and now get 'failed to check for updates': - when I manually check (help > about Firefox) (see image) - in 'settings' it also shows 'failed to check for updates' (see image) I never had such a problem with previous versions; any suggestions?

I have Windows 11 and Firefox 124.0.2. Firefox keeps asking to reinstall. I think it is because I keep getting the message that it fails to check for updates. I don't know if I have installed the Microsoft Firefox or the direct Mozilla Firefox downloaded. Maybe that is the problem, but I am not tech savvy. I have used Firefox for many years and like it. I am also too old (83) to deal with these problems. Help!

'bold text'bold text FIREFOX NO LONGER WORKS WHEN YOU CLICK ON THE LEFT ARROW TO MOVE TO ANOTHER ARTICLE. I HAVE PAGES & PAGES BEHIND THE NEW ONE IT ALSO HAS A BLUE LINE UNDERNEATH THE ICON THIS HAPPENED ONCE BEFORE & I FOUND A WAY TO FIX IT, AFTER WELL OVER AN HOUR WORKING ON IT i CAN'T I WANT TO DELETE IT

I've been trying to delete cookies and site data multiple times and it will not delete, even after multiple attempts to fix it. Such as deleting Mozilla folder in file explorer and downloading an extension to delete cookies and cache. Everything else gets deleted fine except for 2 sites.

Web cam image on web page stopped working after last update. Using win 11. Tried refresh, worked last time but not this time, checked permission security settings. Can get the camera image on a tablet but not laptop. (lenovo) Anything I might have missed?

I do not get my emails on my desktop. My email address ends with ---@ comcast.net. I can be reach via text on my Iphone. Thanks, Al Mizrahi

I am using theme called WhiteSur to imitate Safari, as that is the browser layout I prefer. However, this doesn't change the position of the close tab button and leaves it on the right hand side. I found a way to change it, using the code .tabbrowser-tab .tab-close-button {

 margin-left: -5px !important;
 margin-right: 2.5px !important;

} Unfortunately, this doesn't change based on the size of the tab, so if I set it to a size that is good for only having 1 tab, it will look bad or be off the screen for the other amounts of tabs. Is there a way to detect the width of the tab or the amount of tabs open and dynamically set the margins based off of this? So I could set it as (width-of-tab)-x and that would always keep the close tab button in the same spot, regardless of tab size. Thanks!

In numerous cases i have found not to be beneficial when website's search function is activated on Ctrl+F keyboard shortcut and where is better to use regular Firefox on-page search instead. I think that the good site has search button/area visible so i can use it when needed.

So please how to disable Firefox's search (Ctrl + F keyboard shortcut) to activate website's internal search? I want to always use regular Firefox on-page search that i now trigger by left Alt (to show the FF menu), click Edit menu, click Find in page.... (since Ctrl+F is occupied by website's internal search).

I'm running a UI deployment with a web-app and Firefox on an Ubuntu system.

I'm running Firefox with the flag "--kiosk" to place it into kiosk mode (booted from the command line upon system boot). This works fine, and boots up Firefox to the page I want (my web-app) in kiosk mode (full-screen, etc.)

However, I get very annoying popups that are not acceptable for deployments in front of customers. I have tried, but CANNOT suppress all of them, or, when I thought I did, they came back a month later.

Popups:

1. "Keep pesky trackers off your tail. Open my links with Firefox" 2. "Welcome back" 3. Others like this...

These are Firefox browser popups, not related to popups that other websites can put up, and block the entire screen with an overlay until they are dismissed. My deployments are only going to a single web-page that I control (which has no popups) and there is no keyboard on the deployed system, so people cannot navigate elsewhere.

Things I've tried:

1. Firefox is installed via snap, which provides "snapshotting" configuration for the Firefox snap. I loaded Firefox, cleared the annoying dialogs, and then took a snapshot (theorying that I set Firefox configuration when doing this, and I capture that in the snapshot) and re-installed it onto a new system. Still go popups 2. Looked into user.js preferences. I can install this file onto the system, so I looked through https://searchfox.org/mozilla-release/source/remote/shared/RecommendedPreferences.sys.mjs and this is how I initially got all the popups to disable themselves. I looked through that list and tested most of the recommended settings until the popups disappeared. However, after a month or so, I'm beginning to see the popups again.

Any suggestions from Mozilla or others that run into this issue?

Am trying to update my email address. When I try to make the secondary the primary, it wants a verification code entered. The field for this code will not let me paste it or enter it manually. Will this glitch be fixed soon?

I get the following message when going online with Firefox: "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem." I've followed all the prompts to restart the computer, refresh the computer, delete the favicons.sqlite and places.sqlite and it won't allow me to delete them. This happened yesterday as well. Yesterday I could delete those files and everything was restored. But today I can't get it to work.

I received a scam Apple (security) popup (on which I never clicked) and from that point on, some 30+ obsolete tabs congregate across the top Firefox browser window. How do i lose all these unwanted tabs?

Hi,

I have managed to figure out ways to remove items from context menus from various pages here and around the web however it always seems to leave an additional unwanted separator line that I cannot find how to get rid of.

There are a number of additional lines I am looking to remove but the current one that is annoying me (based on most usage) is the additional line between 'Copy Link Without Site Tracking' and Search which is an add-on - Simple Context Search - https://tinyurl.com/yck5c (as shown in the attachment).

I did have 'search google for...' directly above the 'Search for Google' option which I removed.

I also removed 'Copy Link' which was above the 'Copy Link Without Site Tracking' option which I also removed.

Hope the above makes sense and any help greatfully appreciated.

Thank you

Greg
