Firefox 技術支援討論區

I believe this issue started today. When I print using the Firefox dialog box, all of the printed pages are in color even though the color mode is set to Black and White. I have not changed any of my printer setting and have been using the same printer for many years. The printer is an HP Officejet Pro 8600. I have Firefox version 116.0.3 which was just updated today to that version. When I use another browser (Google Chrome) the pages are printed in Black & Whte. Therefore this appears to be a Firefox issue. I am using Windows 10 64 bit. How can this problem be corrected so that the pages will print in Black & White when I use the Firefox diaglog box? Thanks.

I know the answer to this is probably going to be along the lines of this is not possible, but I thought I'd ask anyway since none of the information is entirely clear. Or answers my exact question.

I have one desktop install of firefox and I have two android ones. I have all three synced to one firefox account, so it's easy to grab links I saved while wiki diving on something. While this works perfectly for the desktop side of things, the mobile side is where the issue arises.

Currently all my bookmarks from both mobile firefox accounts are merged into one long set, regardless of device. While the desktop ones have their own folder. Is there a way to keep the bookmarks from each device in their own separate folder? Like say instead of having one big mobile bookmarks folder, having one named DeviceX, and the other DeviceY?

It's still semi functional on desktop where I have more screen real estate and have to deliberately go to the mobile bookmarks folder, but on the phones it can be confusing when a set of bookmarks from device 1 mixes randomly into those of device 2. As it can become a lot harder to keep track of things.

Now I know one can turn off syncing of bookmarks. This is not what I'm looking for as I do still want to be able to share them between all three devices. Just have them more organised.

I also know one can make different accounts for say work or personal, but again I want them all to sync, just not mix them into one list.

So in short is there a way to be able to have two android devices into a threeway sync and keep the bookmarks separate? Or is my only option the round abound way of making subfolders and hope I remember to save in those?

Thanks either way.

In this website, written in markdown if I'm getting this right, the equations are not displaying in my browser.

My browser is displaying corretly all the examples in the other questions on math rendering, and also in similar books (here, here).

I've deleted cookies and cache, disabled extentions/adblocker, tried safe mode, without any change.

I have the same problem with all Edge and Chrome too and even on another computer. I thought the problem was in the website but the equations are rendering fine when I test them on https://www.browserling.com/.

Thanks in advance for any help :D

I used to have the Tab Mix Plus extension which no longer works in Firefox.

The one feature I really miss from this extension is the ability to alternate between 2 tabs by clicking on one of them. I know that there are various extensions that allow you to switch tabs using shortcut keys and I do use the Switch to Previous Active Tab extension which is useful but I do miss the simplicity of being able to just click on a tab to switch to the previous and even after several years without it I still often try to do it, forgetting that it no longer works.

Is there any extension or setting that can reinstate this feature?

Hi I am getting this message when trying to view the `preview` of an item that I am listing on the ebay site.....Firefox Can’t Open This Page

`To protect your security, signin.ebay.co.uk will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window.`

I have no idea what this means? but I cannot see the preview on ebay. Everything is up to date and was working a few days ago. Thank you.

Hello,

Before today, the add-on button shaped like a puzzle piece in the Toolbar would open a list of extensions I have installed, allowing me to access settings for those extensions. Now, when I click on it, it just takes me to about:addons. Is there a way for me to revert this so that it brings up the list as usual?

Thank you.

Firefox is slowing my computer to a snails pace. Your "help" page said to go to about:config. I don't know where to find about:config. Your software doesn't say where to look for it or a place to look for it. Your help is no help at all. I don't have time to look at forums that in my 25 years of using computers I have never found an answer to a problem I have had in forums.

I did something to my settings before, and I am not sure what, but now I have a very very very limited space for how much stuff I can put on my firefox toolbar at the top as far as add ons, and extensions. When I try to download an app, it is difficult to access the add on because it can only be accessed sometimes, by the little puzzle piece icon next to the add ons on the toolbar, some of the apps are automatically in use no matter if they are on the toolbar, puzzle piece icon or not, but some seem to not be accessible at all other than opening up the settings for all of your extensions, which makes things so hard and slow. I will post a picture of what I mean.

A couple nights ago my menu bar disappeared. I'm running FF 116.03 on an older MacBook Pro. I have now spent several hours searching on what's gone wrong, but none of the following have proved fruitful:

• Closed FF and restarted
• Uninstalled FF, restarted my MacBook, reinstalled FF
• Customize Toolbars (only option is for Bookmarks)
• Customize Toolbars > Restore Default
• Right click on Toolbar (which has always worked in the past)
• Restarted my MacBook multiple times after reinstalling FF
• Disabled sync on my laptop and iPhone
• Checked every setting for General, Home, Privacy, Sync)
• Troubleshooting mode (several times)
• More Troubleshooting information
• Themes and add-ons (I've never used anything but the default theme)
• Everything in this FF Support Article: Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems
• The suggestions in this FF Support Forum page: https://support.mozilla.org/en-US/questions/1391417#question-reply

And probably more things I cannot even remember at this point. I'm beyond frustrated as all I seem to be able to do is show/hide the Title Bar.

I can't seem to find anyone else reporting this issue.

When going to NCL.com the page takes a long time to open, then is just straight text. Tried refresh and it still does the same. It comes up in a few seconds, properly, with Microsoft Edge. I am sure there is a setting or something just do not know what one. Also, this happens on 2 different computers one is Win10 and one Win11.

Hi Team,

I am not able to see from profile with old device and that data and that is very critical for me.. is there any way I can get from Firefox if I provide details...

Thanks Team..

I have tried to make sure cookies are enabled at BigFish.com website but I have probably made things worse or did it wrong. Both problems follow me around and please understand I have also been in contact with BigFish techs but I am not getting far in any solution.

I was told to clear the browser cache which I have done both for Firefox and BigFish but I can detect no difference at all. I am still told at the BF website that cookies are needed in order for me to enter.

I am at my wits' end with this and at my age of 83 I feel like I am rushing on that downhill slide much more quickly due to this problem. I feel that I have made some error in my wildly clicking around but I don't always understand the terminology exactly.

If anyone knows how to explain this to me in perhaps easy steps I would be most appreciative.

Thank you,

Gail

Hi folks.

I use Firefox a lot. I have about 36 windows of firefox open and some of those can have a LOT of tabs on/in them.

I have recently "evolved" to using a computer monitor. Before then it was an old flat screen TV - 1336 x 768 resolution (there about).

Now I have a 1080p monitor and things are different.

I use Node-Red (dashboards) and they took a beating with the new size.

I've set THOSE tabs to 133% magnification - and yes that isn't the correct size to emulate the TV. But I only thought of doing this a fair way down the track of trying to rearrange the layouts. (MY MISTAKE)

But I realised that at least not too long down that rabbit hole.

So that WINDOW is set to 133% zoom. But just now I tried to zoom out of another tab on that window and realised that the zoom on the other tabs is changed too.  :(

Am I missing any tricks? I know I could move THOSE tabs to a whole new window and that's that. But in the bigger picture I just want to check.

Since a few days, it is not possible to copy-and-paste any external text or content into the text field of WhatApp Web on Firefox. It works fine on Chrome. Also text manually copied from a previous WA message can be pasted.

We tried on other PCs with Firefox and Chrome, same situation. So it seems to be a problem of Firefox latest version.

- Windows 11 will crash after using firefox to open a sharepoint link. - It will cause high cpu high memory and high disk. - The issue can reproduce 100% - Chrome will not have the issue.

I usually do the copy and past from other pages to share with WhatsApp, but since yesterday I was unable to paste the links or any articles into WhatsApp Web

Any issues with FireFox with WhatsApp web or sonthing else

Whenever I try to go to the USA version of USA Today, I am redirected to the EU USAT homepage. How do I stop Firefox allowing this geographical redirect to happen?
