Firefox Support Forum

I am experiencing many times that Firefox prints garbage, not what's on the screen. To get around the problem I switch to Safari.

Is anyone aware of this or I am the only one experiencing it? Is this a known bug?

One example:

https://www.amazon.com/Delta-Faucet-U6300-Handshower-Mount/dp/B0064TYA4S/ref=sr_1_5?keywords=grab+bar+shower+holder&qid=1655171785&sr=8-5

Prints little circles...

If I switch to Safari, I get on paper what I see on the screen.

I am using the latest version of Firefox with Mojave on a Mac.

Lately I have experienced slowness despite the fact that I didn't add any software and I have Norton checking for viruses. Recently I got a message "Your system has run out of application memory" when I had 5 tabs open in Firefox. I checked Activity Monitor and it showed Firefox using 1.16 GB. 7 other apps were open, the next one with the highest memory usage was Mail (465 MB). Activity Monitor showed 30 instances of FirefoxCP Isolated Web Content entries.

I attached a screen capture showing what Firefox was using in one of these instances. Is this "normal" with 5 tabs open?

I closed the open tabs and quit Firefox. Memory usage by Firefox went down, but after a short time the problem happened again.

A search on the internet showed lots of similar complaints about FirefoxCP Isolated Web Content. Is this a known bug? Any way to avoid this problem?

Thanks.

This again!

This was resolved about a year ago; now the problem is back, as of updating to Firefox 113.0.1 this evening.

Initially post-update the close tab button was in a weird, random place on the tab bar. I have adjusted the margins to put the button back where it's supposed to be!

I changed :

.tabbrowser-tab .tab-close-button {
  opacity: 0;
  margin-left: -4.5px !important;
  margin-right: 2px !important;
}

to:

.tabbrowser-tab .tab-close-button {
  opacity: 0;
  margin-left: -4.5px !important;
  margin-right: 35px !important;
}

to move the button back onto the left. That may seem like a drastic change but that's the lowest value I could find which produced the result I want.

However, it's not quite the result I want! As of updating to 113.0.1, the tab title itself now disappears altogether on hover.

I have tried to correct this in CSS using the .tab-text and .tab-label attributes, but without any luck so far.

Can anybody help me with this, before I'm forced to downgrade to Firefox 112?

Better yet... how about we just make this an option in Settings, as it should be?!

When I use Firefox on my Mac, no matter what I have tried it keeps defaulting to the dreaded Bing Search Engine. I understand it has to do with Microsoft, but I don't use any of their products because I don't like them. In settings/search I can restore the default search engines & delete Bing, but it always reverts back to insisting on using Bing again. I have followed several threads about this issue without permanent resolution. Help??

I searched in Google and this website for instructions for how to delete specific cookies for a website. Many instructions are probably for older versions of Firefox.

I used to be able to login as of this morning to Wizzair.com. Then suddenly, regardless what I do, I can no longer use Firefox to login. I used the Preferences/Privacy & Security/Cookies & Site data/Manage Data for Wizzair.com to remove the cookies for the website, but it didn't help. I changed the password, it didn't help.

Their chat support sent me to their Privacy statement. There, there is custom list of cookies that they use. I was told to try to delete them individually... I have no idea how to do that and I could not find a method that works.

I can login the website using Safari. Any suggestions for what to do to be able to use again Firefox to login into this website? Thanks in advance.

I can't figure out how to delete this extension: Adobe Acrobat. It's disabled, but I want to delete it.

Hi all, the shortcut to close a single tab (ctrl+W (Windows) or cmd+W (Mac)) is not working anymore.

here is what I tried so far: - disabling all extensions (via restart in safe mode) but to no avail - reinstalled Firefox but the problem persists - verified, that the command is indeed cmd+W and was not changed by accident - all other shortcuts are working well

NOTE: I can see that when I press cmd+W, the "file" tab up above on the Mac menu bar flashes for a brief moment, as if the system detects the shortcut. But the tab stays open.

Any other ideas I could try out?

I learned the hard way about a month ago that my main bank will not work with firefox. I've now received notices from two other banks that state they only support safari on Mac. I have run into issues with some others that will either give errors but still allow me to pass through or others that state I have an unsupported browser but still allow me to log into the site - for now.

With this wide a net, this seems to be specific to the security issues in the Mac browser. Is this already being looked into? Is this specific to the new OS and firefox integration?

While I basically trust Safari, I certainly don't want to use it unless I have to and I generally use firefox exclusively on all my Macs and PCs. Can someone shine a light on this? Is there an upgrade or update planned?

Thanks

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?

I've started getting this error message on certain websites (always the same ones):

The page isn’t redirecting properly

An error occurred during a connection to www.manek.org.uk.

   This problem can sometimes be caused by disabling or refusing to accept cookies.

The same websites still work fine on Firefox mobile, so it's nothing inherent in the sites themselves.

I have only noticed this in the last few days. I had just updated Firefox to version 109 – but it's not specific to one version of Firefox either, as I tried on one of my Macs which hadn't updated yet and is still on version 107, and the issue was replicated exactly the same.

I have tried clearing the cache, restarting Firefox, etc.

Can anyone help me resolve this? Some of these are websites I use quite a lot for my work, and it's frustrating to have to do anything just on my phone.

Hi:

I tried to set cookie preferences for different websites. For reasons that I do not understand, I cannot move the "slider". I even turned of the existing protection for the websites, but nothing changed. I tried the same with Safari using the same computer and mouse, and I had no problems.

Is this a known bug?

I attached a screen capture. Thanks.

Someone else asked the same question a while back but the answer doesn't work for me.

The previous answer: 1. Make sure you have "Ask to save logins and passwords for websites" checked in your browser. To check that, Open Menu->Options->Privacy & Security->Forms & Passwords 2. If the above check box is checked, then whenever you enter username & password in any website Firefox will ask you to save username & password 3. Click on Don't Save. So Firefox will save the user name in form data. 4. When next time you open that website and click on user name it will show you the list of entries(If you used multiple use names on same site else will show only one user name) available for that filed.

I get no list of user names.

I just updated the browser. Just prior to doing that, I used used this website https://www.carpetmdinfo.com/ without any problems. Now, as click on the different tabs of this website (Home, About Us, Our Cleaning Process, etc.), nothing happens. The same website works without problems with Safari.

Does anyone else experience similar problems?

I looked at reporting the problem as a bug, but I am sorry, it is too complicated for me. If someone could replicate the problem and report it, if in fact the same happens to others, I'd appreciate it.

Hi,

does anyone know what to do to make the background of the bookmarks icon and the reload icon the same as the icon with the site connection lock? I've exhausted all options in the userChrome.css and cant get the background to change. It's in hover state.

For reference I've added a couple of images, the first how the background is and the second how I would like it to look. I'm on macOS and latest Firefox 111.

Best regards,

Johnny

I'm on Windows 10 Auto updated to 108.0.1

UI is broken. See image.

Works in safe mode though.

How to fix?

Or at least guide me on how to backup all my config and create a new profile. Thanks.

Hi there,

I've got plenty of bookmarks organized in folders and sub-folders (never could wrap my head around using tags). Normally, hovering on top of a folder or sub-folder just opens it. However for some unknown reason, some folders just don't open on hovering. By contrast, opening the "Manage bookmarks" pane shows all bookmarks are there and functional. The issue only appears in the menus, and I'm not sure when it appeared exactly.

Already tried: Renaming faulty folders: no effect Moving bookmarks into a newly created folder: no effect Moving faulty folders into an already-working folder: works, except if the folder is the one containing the root menu.

Screenshots: A working sub-menu: https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2022-08-01-10-56-24-be01e3.png

Two different, non-opening submenus: https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2022-08-01-10-56-43-4a4bb1.png https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2022-08-01-10-56-50-615eee.png

How to solve this strange issue?

Hello Team,

Firefox does not play well with how you customize keyboard shortcuts on Mac i.e. Go to System Preferences > Keyboard > Keyboard Shortcuts.

By default - Move Cursor to Address Bar - Cmd+L Bookmark this Page - Cmd+D

I would like to switch these two shortcuts but there does not seem to be any way. Please help me out.

Thanks, Naman

I'd appreciate easy to follow steps (for the last version of Firefox for a Mac using Mojave) to locate cookies for only ONE SPECIFIC website and delete them.

Thanks.
