Firefox supportforum

My Firefox has gotten so buggy lately I can't use it. I'm writing from Edge. THere are numerous issues. The sign in process got messed up a couple months ago. IT asks for email address, then doesn't provide password screen option, takes forever to send email, and then sometimes repeats itself. Tabs crash and clicks fail to work randomly. Out of desperation I reset my Firefox password and that seemed to help temporarily, but not enough. So what's happened and how to fix??? Thanks.

Bing says my browser is the one to set my SafeSearch on strict by default, but I can't find the option to turn it off. Is there even an option or is this a Bing issue?

When typing if I make a mistake I'll usually just delete the entire word and retype it rather than fix the spelling but to do that I need to use CTRL. Now when I press CTRL it zooms in the page even though there are no other buttons being pressed.

As I understand, `autoconfig.js` (with `firefox.cfg`) can be used to have JavaScript run during startup to control Firefox's UI elements.

I have set up `autoconfig.js` in my `/usr/lib/firefox-developer-edition/defaults/pref` folder (I'm on EndeavourOS Linux). As instructed here, I've already put the two required files, `autoconfig.js` and `firefox.cfg` in their correct folders (`/usr/lib/firefox-developer-edition/defaults/pref` and `/usr/lib/firefox-developer-edition` in my machine).

The file `firefox.cfg` contains the following code:

 //
 (() => {
   var tabbar = document.getElementById("TabsToolbar");
 })();

However, every time I run Firefox, this message will appear:

 "Failed to read the configuration file. Please contact your system administrator."

If I empty out the `firefox.cfg` file, Firefox will run normally without showing the error message. It will also run normally if I just have something like this in the file:

 //
 (() => {
   var testVar = "";
 })();

I don't understand why the JavaScript code can't access the Firefox UI elements through `document` or `window.document`. If `autoconfig.js` isn't build for that, what should I use to change my browser's UI elements through JavaScript?

Thank you.

Yesterday, I ran a format on my computer with Firefox in installed on it. When I tried to recover my settings, history and bookmarks later using sync after logging in to my account nothing happened. Can you please help me recover my data? Thanks in advance.

Hi, my bookmarks toolbar doesn’t show when I launch Firefox. They always use to. When I click on View>Toolbar>Bookmarks Toolbar>Always Show - the Bar shows. When I click on any bookmark the bar disappears. If (in new window) I click on View>Toolbar>Bookmarks Toolbar>Always Show - the bar appears, when I then open new tab it does not show on new tab and when I click back to previous tab bookmarks are gone.

I have restarted W10 PC, no change.

Hope you can help, many thanks, David

When I try to screenshot (Windows+Shift+S) and paste the screenshot into Google Translate, I get the error message:

Unable to paste from clipboard right now. Try copying the image again.

This functionality works in every other browser I've tried (Chrome, Edge, Brave, Opera GX), so it's not a Google problem, I don't think.

Twitter's login page won't load when I try to open it in Firefox. https://twitter.com/ https://twitter.com/ loads just fine, account pages like https://twitter.com/firefox load just fine, and individual tweets individual tweets load just fine. But when I click the login button on any working page, or go directly to the login page at https://twitter.com/i/flow/login, all I get is a white rectangle in the middle of the screen that flashes a loading-spinner for a few frames every two seconds but never actually loads any page content.

I can log in just fine in Chrome, so the problem is specific to Firefox. The problem started at least a week ago, but I don't log in on my desktop regularly enough to know exactly when the problem started.

I turned my Browser Privacy setting to "Standard" and cleared all site data from Twitter, with no effect. I use uBlock Origin, but the problem persists when I disable it. The problem also occurs in Private windows.

Hi folks, So my university uses gmail and accesses with Duo Mobile. I usually use Firefox on a Win11 PC, no problem. This morning for some reason firefox will not let me even begin the login process. Chrome works fine. I have disabled four extensions (DuckDuckGoprivacy, Unpaywall, YoutubeNonstop, Boomerang) and restarted, no change.

Screenshot shows errormessage on Firefox, with functional Chrome screen in background.

This has to be a firefox issue? help please!

Hi,

I'm trying to remove the bar at the top of firefox browser with tabs in them. I read another article (https://support.mozilla.org/es/questions/1417387#answer-1588947) under spain link, i think, and the solution said to write "TabsToolbar-customization-target { visibility: collapse !important; }" somewhere. Where do I go to write that?

I tried the console by pressing f12, but that doesn't seem like that's it. In that article it also mentions to go to about:config and change the status of "browser.tabs.drawInTitlebar" to false, or delete it, but didn't work either.

I'm not very good at English, so I use a translator. After updating to the latest version of Firefox, the problem I'm having is that when I play a YouTube video on the web side, the playback box will have a large white colour, as shown in the red box below. I would like to know what is causing this, my current version is 123.0
