Firefox Support Forum

I am using Firefox on an old Ubuntu machine, and found myself unable to disable the auto update feature of Firefox. I understand why Firefox wants to do auto update, but for me personally it's negatively impacting my productivity. Many times I was looking up reference materials only to be told that I need to restart Firefox because it just updated itself. Imagine how frustrating it is, especially when I use the Private Browsing mode a lot to avoid having to clean up browsing history and cached files later. All in all, while the auto update feature might be good for some users, it's just not working for me, so I want it to be disabled.

I tried a couple of things. First, there's nothing in the "Preferences" page related to the auto update. Second, I tried to change the value of "app.update.auto" in the "about:config" page to false, and it still does auto update. Finally, I tried to add a "policies.json" file to "/etc/firefox/", with the following content:

{ "policies":

  {
    "AppAutoUpdate": false,
    "DisableAppUpdate": true,
    "DisableTelemetry": true
   }

}

Yet it still does auto updates. As a matter of fact, it updated itself to version 80 just now. This driving me crazy. Any useful suggestions will be sincerely appreciated.

I use the Bookmarks Bar extensively. But all the folders are the same color. I would find it much easier to find things quickly if I could change individual folder colors.

Any way to do this?

I'm already using Jscher's excellent UserChrome script to make the folders an attractive yellow, instead of gray. But can this be done for individual foders?

Recently (~2 days ago) I would be scrolling down a website and the text would glitch out into black/white/colorful squares. Now it happens randomly and I don't know what causes it. The glitch would follow as I scroll, and I could refresh the page or highlight portions of the text to get rid of the distortion. I have tried quitting out of Firefox, booting it in safe mode, and uninstall-reinstalling it. None of that has helped. Attached are screenshots of the glitch. It seems to be getting more frequent (?)

I did some system scans/diagnostics to check that it wasn't a hardware issue, and there's no problem on microsoft edge or other applications like discord/steam, so it seems to be a Firefox issue.

Letters (most noticeably x, y, and z) appear to be missing from text in web pages. Running macOS 10.14.6 with Firefox Browser 80.0. Note the image from the drop down menu on this support page. Missing y's, z's, and x is replaced by quotation marks (ie Firefo" Snc).

I have seen this sporadically on a couple of macs that I own. Text seems okay in Safari.

Thank you for your help!

Some months before I used to have an page loading icon which was some dots, going left to right and backwards. Recently, I have got an hourglass which I didn't know how I got it and it doesn't look as neat as the previous one.

I have a new HP printer and I am using Firefox from a Windows 10 PC. I am plagued with Paper Mismatch errors when printing emails from Firefox. After a lot of trouble shooting, I have found that this problem seems to be confined to Firefox, as it does not happen when using other browsers, e.g. MS Edge. I have tried resetting all Firefox printer settings and the problem still happens when opening Firefox in Safe Mode.

The print job stops with the error message Paper Size Mismatch after the 1st page, and printing will not continue or even move on to the next job until the error is cancelled from the printer's control panel. This means I have to be working next to the printer and cannot print remotely.

In the printing dialogue box under Printing Preferences, the paper size shows Letter, whereas I am using A4 in the printer, and this is the mismatch causing the problem. I can change the paper size in Printing Preferences from Letter to A4, but I have to do this for every job seperately as the paper size setting always reverts to Letter. This is totally impracticable.

Regretably, I will have to stop using Firefox unless there is a solution. Can anyone help me to change the paper size setting to always default to A4, please? Thanks in anticipation.

When I choose any other option then remember history. Ebay page does not display properly. Only way to get it working is to choose remember history.

Please fix it as I just don't like my browser to remember history

I do web design. And my problem is that I used to click the refresh button in firefox and it would instantly load an updated version of the pages I was working on. But now it does the exact same thing I hate about chrome. It loads pages using cached css and javascript files. And the only way to view the updated websites is to go private mode which is very annoying. Is there an option to get around this? Or it's a software problem?

Since two weeks ago, Firefox has downloaded stg-backup-[date]@drive4ik.json files in folder "STG-backups-FF-80.0.1" under downloads.

I have no idea why and I want it to stop. Anyone know anything?

I'm using Gmail in Firefox 80.0.1. When there is a Word or .pdf attachment on a gmail message, clicking on the attachment opens the dialogue box attached below. Despite checking the box, "Do this automatically for files like this from now on," the box continue to pop up with the next attachment on another email. Is there a way to make it "automatic?"

A few weeks ago, Soundcloud stopped loading, but only on Firefox / Win10 PC even after disabling ad blockers. The site continues to work in other browsers and mobile apps. It began to work again in FF for a short while, but it's been down a solid two weeks since. I've put in a support request with Soundcloud but never heard back.

No errors ever appear, it's just completely blank. Site-wide. Nothing will load. I can't find anything online describing this issue.

I'm dreading having to wipe out all of my cookies, history, cache, saved logins/passwords, etc. and I'm hoping there is some other recourse. Any help or suggestions would be greatly appreciated!

When I'm using FF on my Mac, Catalina OS, and click on telephone numbers in websites, they always open up Skype, which I don't want them to do.

Instead, I want them to take me to Facetime and dial the number there.

Is there some configuration in my Preferences or an add-on that is causing phone numbers to open Skype instead of Facetime?

What can I do to get it open Facetime and dial there instead of Skype?

I have a web sites, www.canadiantire.ca, that worked up to the latest updates. Opens home page; select search and enter any search term; hit Return/Enter and get "400 Bad Header", "Request Header Or Cookie Too Large"

Why am I getting this? Canadian Tire says that there web site is developed for Google Chrome (which I an not in favour of switching to)
