Firefox 技術支援討論區

I use mozilla firefox as my main web browser, and youtube sometimes does sometimes doesn't load (picture below). This happens only on firefox. Every other website works fine tho.

When I open a new tab in FF, a row of 8 boxes appears below the search bar where I can add shortcuts. I currently only use 5 of them, meaning there are 3 empty boxes left over. I don't want to have them show history, or recommended websites, or anything of the sort that might distract me; the shortcuts should only be those I actually intend to use, of which there are only 5. To my knowledge, the only easy way to add/remove shortcuts is to adjust the number of visible rows, but this only allows modifications based on multiples of the original 8. Like in Chrome, can I actually remove any excess shortcut boxes I don't want to use? I feel this is a very basic customization I'm sure Firefox should be able to accommodate.

I've included a screenshot of my FF new tab, where the three empty shortcut boxes I'm referring to can be seen. Thank you in advance for any assistance!

I recently noticed that fields on all Web sites I visit have an extra horizontal line at the top of the prompt. Please see attached image. This only happens on Firefox. Other browsers don't have that behavior. How can I restore the normal prompt of a straight vertical line?

Thank you!

When i try to open youtube.com for example i used to only type in you or even you y for firefox to finish the whole URL for me, but sometime last month it dissapeared and never figuered out why after ALOT of trouble shooting to the point where I felt the need to create a new firefox account. Can you fix this for me? or just make everything deafult?

Some Hebrew fonts are appearing as little rectangles , when I turn off 'allow website to provide fonts' then even more of the Hebrew (not just the Heb on buttons) appear as rectangles (see images) .

For a couple of weeks now, out of nowhere, links I click from emails sent to me open in new tabs but are blank pages. This includes download links, so I'm unable to see any links or download anything being emailed to me by a number of senders. Weirdly, some senders' links work. I didn't change anything and don't know what to do about this. Please advise if you have a solution, thanks!

Hi, Many times my images won't load on Firefox, but they do on Google chrome. I have disabled all my extensions and it still happens. I even went in and explored this option recommended by firefox: browser.display.document_color_use to the Search box. The preference's value should be set to 1 by default.

Please help! This is so frustrating and I love firefox. Here is an example of what I mean: I log on to https://www.tummee.com/yoga/poses/library to see yoga poses and I get all the stuff but the images of a yoga pose; however, google chrome loads the images. This happens on other sites too. I use a Mac and my Firefox is up to date: 121.0 (64-bit).

Hi,

I've been using the following in userChrome.css for many years

1. menu_close { display: -moz-box !important; }

to restore "Close Tab" in the File menu, based on cor-el's response regarding restoring menu_bookmarkAllTabs here:

https://support.mozilla.org/en-US/questions/799856

This stopped working some time ago and I am finally getting around to asking why.

I do have toolkit.legacyUserProfileCustomizations.stylesheets set to true, and other items in userChrome.css are working.

I am using 121.0 at home and 115.0 ESR at work and see the same (i.e. no "Close Tab"), in both cases on Debian testing. I do see this menu item when using the keyboard to open the File menu.

Any idea why this no longer works?

thank you, Greg

When I try to download a file from a a download link from a trusted website it doesn't work. When I click it it just refreshes the page and doesn't download. I'm new to PC so I don't know if its something simple or if I may need to uninstall and reinstall Mozilla. Thanks in advance for any help.

My Dell Laptop INSPIRON 3793 running the Firefox/Mozilla Browser when I stream in Youtube or LiveNews periodically goes into the images in the photos I uploaded here. I am compelled to do a hard restart. I have been working with Dell Technical Services and they indicate they have no history of this issue. I am running Windows 10. My system has all technical updates including current drivers . I really do NOT want to move off FireFox but I getting pressure to run another Browser and wait and see if the problem surfaces. Is there any history of this issue with this Firefox. Any help or insight you can provide would be greatly appreciated. Thank you, Cate Brown

Hello, when i click the 'extensions' icon in the toolbar, it redirects me to the extensions manager site, rather than opening a little popup with a list of extensions. How do i fix this so that the popup appears again?
