Diễn đàn hỗ trợ Firefox

So, I just now installed Firefox and now I want to change the background of the home page (new tab), the same way you would do in chrome. I did some research and created a chrome folder and a chromeContent.css file in there.

I tried first the code in this link: https://support.mozilla.org/en-US/questions/1271362 and then this one: https://superuser.com/questions/1495946/how-do-i-change-the-background-image-of-home-page-in-firefox

neither of those worked, even though I'm pretty sure I followed all of the instructions correctly. help please, will be greatly appreciated (i don't know if i chose the correct topic)

pictures included in order: the code (device name crossed out), inside the chrome folder, inside the profiles folder

Hello,

I would like to know if it's planned that Firefox uses macOS abilities like on Safari, such as text replacement and others ?

Kind regards

Since the latest update to my Firefox, videos (for example, in documents such as surveys) either do not load or they freeze. And in some streaming applications, either they play with no sound or when sound is turned on the video freezes. This was never a problem until recently. iMac desktop (2017) Ventura 13.7.4 Firefox 136.0.2 (64 bit) The same issue does not occur on Safari or on my iPad (using Firefox). Any advice?? Thanks.

Hello Can you please help me find an adblocker for old Firefox 78.15.0esr. I have looked everywhere.

I have to stay on an old OSX (Mac 10.11) and use Firefox 78.15.0esr (for various reasons I cannot upgrade). I had an adblocker that worked brilliantly, but a few weeks ago it was removed (not by me), so the Ads came back!

Recent attempts to download ad blocker as before were not successful. ?incompatibility I think.

Many many thanks Jane

Hello, After the last MacBook Pro M4 update my tabs keep disappearing. This is quite ANNOYING as I use ALL my tabs. Plus when I go to HISTORY there is NO Restore Previous session...so I am losing EVERYTHING. Do I just need to go out to another browser and make them my default? I can find NO help when I go out to your support for my problem. Thank you, Patty

I use google meet at work. Up until recently, things were working ok. Starting a few weeks ago (there were updates both to MacOS and Firefox), when I was in a meeting, the other side couldn't hear me even though meet said that my microphone wasn't muted. I then switched the meeting to Safari, and had no problems. I also noticed that when the remote party did a presentation, it did not show up when running on Firefox, but switching to Safari it worked. This is clearly a bug (or a miscoordination between Firefox and MacOS). Has anyone else encountered this? I'm running on a M4 MacBook running MacOS 15.3.2 and Firefox 136.0.1

I am unable to remove add on themes. The remove button is not provided. Only manage which enables the theme. I do not want these themes and want them removed now. mac ios

'bold text My updated version of firefox does not have my bookmarks, will not print all pages, will not allow to select print in color, will not display images in downloads only text.

1. I downloaded the latest Firefox from Mozilla official website, installed the app, made sure I can see the Firefox app in my applications. I start using the app. 2. Everything will be fine for a few days (say 1 week or 10 days) and one fine day, the browser stops working. Even google.com doesn't open. 3. I quit Firefox and try to re-start it. I cannot find Firefox in my system. It just disappeared. I cannot find in my applications. The search doesn't show Firefox.

I re-install by going back to step #1

This has happened not one time but many times. I searched if others have this issue but did not find anything that i could use. Hence posting this question here.

I have Firefox installed on a lot of other Macbook pros in my home, no other system has this issue. I don'ty understand what is happening. Just wanted to get some guidance in resolving this issue.

Thanks _Krishna

Hello!

As you may know I have great El Capitan laptop - 10.11.6 which is good for over 15 years but suddenly they stopped supporting your browser. I am not able to go to online banking even computer is good. Can you help to do better upgrade on your browser please?

P.

My upper Apple menu is not visible unless I move the cursor up to the top of screen. This is the menu bar which includes the File, Edit, View, History, Bookmarks, Tools, Window, Help, icons and clock. I can't find how to correct this.

Thank you.

I am looking for the folder a particular bookmark/web page is in. Steps I took: Open Bookmarks Manage bookmarks (which opens the Library) In the SEARCH box, I key in a search word, "intention" This brings up a list of possibilities, however it does not show me which folder the bookmark is in.

TIA for your assistance Carol

Hi,

I've been getting a glitch while typing emails in Outlook Web Access for the last couple of days where superscript type in dates looks like the image attached. It was working fine until sometime this week. I've tried using Microsoft Edge and the issue doesn't happen so I'm thinking it might be browser specific.

I'm running Firefox Version 135.0.1 (aarch64) on a Mac Studio with Sequoia 15.3.1 (24D70).

Can you advise please?

Thank you very much.

Calum.

Yesterday I could access my passwords saved in Firefox, but today there were only two & those were in an open window for passwords. How can I recover my list of passwords, please? I'm using a MacBook Air with an M3 chip, Sequoia 15.3.1 Thanks so much!

I tried to print directly from a website, but it will not print. If I print an image or PDF, it will print just fine. I am currently using Firefox 135.0.1 on a macOS Sequoia 15.3.
