Diễn đàn hỗ trợ Firefox

For over a year (just over a year on this computer and a few more years on a different computer) I have had a custom theme at the top appearing from the file menu through the address bar. The computers have also always had the New Tab menu being a light colored screen. I turn on the computer today, to find I guess Firefox updated last night? and completely got rid of the lightness of that page to make it dark, leaving me on the verge of a migraine every time I have to look at that thing.

How do I get rid of that dark page, back to the lighter version WITHOUT getting rid of my custom banner at the top? (yes I tried to use the light extension in theme and that gets rid of the banner and leaves me with a horrible white at the top which is just as big of an issue for me as all the black. I really need that like muted Tan back.)

Hi,

I seemed to try everything I found at the net, but since I updated to Mac OS Monterey, Chinese and other non Latin Charaters don't show up. It works with Chrome and Safari, What's the problem.

I look forward to you help asap.

Thanks, Carolyn

Hi, how are you? How is wondering if you know when you change the default browser in Windows? It shows the portable Firefox browser Along with the installed one. How can I remove that from the system? Please let me know Thanks.

Hi, I check my storage for large folders and I came across folder inside Firefox profile called "cert-revocations" and its size is more than 400MB, can I delete it safely? What cons of deleting this folder? and why Firefox doesn't clean this folder periodically?

Since upgrading to Firefox 99.0.1 when I bookmark a web page into a specific folder, the URL does not appear when I open that folder. A restart of Firefox does not fix the issue.

But if I try to Bookmark the same page again, I am asked to edit it. So it must be in the folder but it is not visible! Help!

Hi I Can not remove Bookmarks. I test all usual ways but nothing happened!i first i test manage Bookmarks and select delete but it did not work... then i made my own account and nothing change... steal i can not delete bookmarks.

 Please help me. 

Thank you

Often when browsing I find that when i want to use spacebar it does something i don't want it to do, which is advance the page downwards, like the "page down" button. I'd like to change that to something else, like maybe the page down key. Thanks.

Hello

I do not understand how firefox sync is supposed to work. I have a desktop and a laptop. The desktop is FF 85 on Linux Mint (I cannot get a later version due to some querk) The laptop is 99 on Windows 10 Both are signed in to sync but my bookmarks were scrambled so I signed out the laptop and cleared the profile, cleaned up the bookmarks in the desktop and to be safe I tried just syncing the tabs, not the bookmarks, by opening the fresh firefox on the laptop and signing in again. In the sidebar under my account icon I clicked "Synchronise now" and the open tabs from my desktop appeared in a list underneath, jumbled up. (I have 2 separate windows open on the desktop with different tabs in each, but this separation was not followed either, there didn’t seem to be any provision for syncing tabs in two separate windows)

But the row of tabs didn’t open, all I can do is open them one by one from the list on the right, this is a slow process as every time I click on a tab in the list the new page opens in the same single tab, not a new one, but the sidebar closes again.

Is this what’s supposed to happen? I was expecting the synced row of tabs to open automatically.

This feature would have been useful as my OS on the desktop, (Linux Mint) tends to crash and to have the on the laptop would be a good backup.

Incidentally the other way I try to back up the lost tabs is to select them all and bookmark them to a new folder which I call “backup” but it seems this doesn’t necessarily duplicate them, which I would prefer, so any of the open tabs that were previously bookmarked risk being removed from the original bookmarked folder, without my noticing, and I am therefore reluctant to delete the backup folder without checking that it doesn’t contain the only bookmark of a page.

When I came back to syncing the bookmarks, how do I avoid them getting scrambled again?

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?

We got an alert when opening Firefox on our iMac yesterday suggesting we "refresh" and that bookmarks and saved passwords would not be affected. After the refresh, bookmarks were retained but all passwords wiped out. Further, as we painstakingly looked up or created new passwords on sites and entered them, the usual Firefox alert would come up asking if we wanted to save the new log-in, user name and password on each site, we'd select "yes" and then find none of them saved. Can anyone advise us? We're rebuilding our saved passwords on Chrome now but have had Firefox as out primary browser for over a decade.

Hi,

In the parameters, I chose to let Firefox ask me every time what to do with PDF files. But, when the window pop up and I click "Open with ... Firefox", the browser download and open with Firefox the PDF instead of only showing it in Firefox. When I set the "Open with firefox" by default in the parameters, Firefox will this time directly open the PDF in the browser instead of downloading it.

Are you aware of this bug ? Is there a solution ?

Thank you very much !

Hey, i just came home from work, started firefox and got suprised by the latest update...and another suprise. My entire Firefox got WIPED, i mean.. EVERYTHING. booksmarks, passwords, settings. I'm sitting here with an totally clean, like new installed firefox...and i'm angry AF right now.

Hello,

My name is Cezar Dobre and I have a problem with my account: - after I have reinstalled my operating system, I tried to recover my old data - I lost my recovery key so I have reset my password - I didn't know that if I do so, my data will disappear - meanwhile I have also found my previous recovery key

How can I get my old data back? Please help!!

Thank you!

Hi, I'd like to disable that annoying animation when going to fullscreen (by hitting F11). Supposedly, setting the following should work:

Go to about:config

Set: full-screen-api.transition-duration.enter 0 0 full-screen-api.transition-duration.leave 0 0 full-screen-api.transition.timeout 0 full-screen-api.warning.delay 0 full-screen-api.warning.timeout 0

Restart

However, this does not have any effect in Firefox 94.0 on Ubuntu. Is this a bug/regression? Or is there some other way to disable the animation?

Good day,

Really happy to see that mozilla is tightening up security. But unfortunately, I can't enroll into Two-Step Authentication everytime I enter code it's not being accepted. I tried multiple android apps of those codes and non of them work for me.

Because of that, I lost access to addons.mozilla.com account, because system doesn't let me in without 2step auth enabled.

Any chance I can use yubikey's intead of those auth apps? or anything else I can do?
