Diễn đàn hỗ trợ Firefox

I'm using this shortcut all the time and I recently found out it doesn't work as expected. From the Firefox documentation the ctrl+shift+t should re-open the latest closed tab, but this is not the case for me, it always re-open the latest closed window. Which behave exactly as ctrl+shift+n.

From my short research it's not possible to customize Firefox shortcuts without using an extensions, therefore I also don't know how to verify if the shortcuts have changed just form my browser/configuration.

MacOS 14.6.1 Firefox 31.0.3 (aarch64)

I have a long (19000px) table with a sticky row at the top. On Safari or Chrome it works fine. On Firefox it works for around 800 px and then becomes 'unsticky'.

Is this a known behaviour?

Netflix says I need the the latest version of firefox. At the top of the screen it says "Firefox is installing components needed to play the audio or video on this page. Please try again later"

As far as I can tell nothing is installing and I need to actually do something to resolve this issue. Unfortunately I don't know what. Please help me resolve this issue.

In recent weeks when I open my Macbook and go to https://meet.google.com, the page that loads says "404. That’s an error. The requested URL was not found on this server. That’s all we know." The issue is only on Firefox and not Chrome or Safari. When I see the error page, I look at the URL and it has the word "unsupported": https://meet.google.com/unsupported?meetingCode=landing&ref=https://meet.google.com/landing

So I dragged firefox to the trash, reinstalled and the issue persisted. I do not have a VPN. I'm using my own Wifi at home. If I switch to my desktop computer (m2 mac ultra) and go to the same Google Meet URL, I don't get a 404 error on firefox, however no one can hear my microphone any more as of 1 month ago, when I didn't have this issue in the past and I've done everything that everyone has told me to (in order to fix it) and nothing has worked.

Laptop: MacBook Pro 2021, MacOS Sequoia 15.0 Firefox: 13.0.1 (64 bit)

I am starting to use the new utility which allows me to group tabs. But I would like to see only the name of the group and not the whole list. How can I collapse the list of tabs which belong to a group leaving only the group name shown. Then with a click I should be able to see the corresponding list of tabs if I need it. Saving and closing a group is not a solution, as the group disappears from the Sidebar. Thank you for your help. Best regards Ray Ballisti [edited] @bluewin.ch Switzerland

Got a number of devices with Firefox installed, all of them Firefox Sync'ed. Most of them on rapid release version cycle and a couple of them on ESR.

When https://support.mozilla.org/en-US/kb/website-translation it provided a clean way to browse entire pages automatically translated. Problem is that the translate option is not there.

I'm at work right now on ESR 115.15.0 / Windows 10 64-bit and no translate icon appears on the address bar when checking German or French or Japanese sites (for example). Comparing my own browser settings to another, non-ESR FF it seems that on ESR something is missing. There is only a reference "Firefox Translations" and a "Exceptions" button to it. Check the attached image.

Can't tell if this is a bug or a feature (ie ESR lacks Firefox translate).

I have a problem on the aliexpress website. (in other browsers everything works fine) When I open tabs with goods on aliexpress. and start switching between them, then at the moment of switching to another tab, my previous tab itself is updated and opens the main page. And there is no way to even press the “Back” button. The browser seems to reload the page completely. The chatgpt was unable to find a solution. All hope is on you. There are no errors. It's just that the aliexpress page reloads by itself when I switch to any other tab.

On certain websites, I see that the background color of the new tab page replaces the default background color making the content unreadable, example:

If I browser this website: https://typespec.io/docs

Here's what I see (see the firsrt attached screenshot). Now, if I open the same URL in Private browsing, the background color changes too (see the second screeenshot). In the 3rd screenshot I'm adding the reference rendering, that's how I expect this website to render (Edge).

In the screenshot 1 and 2, the background color is exactly the same as the one used by the new tab page when I open a new tab.

Questions: 1) Why is that? 2) Can I change that?

Context: I'm trying to switch to Firefox (from Edge)

I've found a solution to the blurriness of the emojis, I've put it in the end of this post, in bold ⤵⤵⤵

My problem is that emojis look bad on Firefox compared to Edge_128.0.2739.79. Two screenshots are attached of bing.com & a Google Doc (left half of both pictures is Edge, other half Firefox). The problem persists on all the sites to a varying degree.

Steps to replicate: A] Open 2 sites in latest Edge & Firefox on Windows 11 (the examples that I've used in the screenshots): https://www.bing.com/ and an Empty Google Doc. B] In the search field of bing and in a new line in an empty Google Doc, copy the following example emojis (That were inserted using the 'Windows_Key+V' which summons the emoji Keyboard of Windows): 🏀🚕 C] Compare the quality of the emojis rendering between the browsers when unzoomed and when zooming.

I've tried in FF (to no avail): A] Disable hardware acceleration in settings (w/ FF restart). B] Setting "gfx.font_rendering.cleartype_params.rendering_mode" from -5 to 5 (w/ 10+ FF restarts). C] Setting "gfx.webrender.quality.force-subpixel-aa-where-possible" to true (w/ FF restart). D] Using both emoji sets in the "Segoe UI Emoji" & "Twemoji Mozilla" fonts in the "font.name-list.emoji" setting, both sets gave me blurry results (w/ FF restarts). D] Disabling all add-ons (w/ FF restart). E] Setting new Firefox separate clean install. F*] In Windows setting the scaling factor to 100% in Windows->System->Display->Scaling_Factor (w/ FF & Windows restart).

How can the blurriness of the emojis be fixed so to make them crystal sharp like in Edge?

Solution: A} Download Noto-Color-Emoji font from https://fonts.google.com/noto/specimen/Noto+Color+Emoji Ensure that your are getting the full resolution font (which came at ~23MB as of 2024.09.23) B} Unpack the font and install according to the on screen instructions. C} In FF in "about:config" find the "font.name-list.emoji" setting and rewrite its value field to "Noto Color Emoji, Segoe UI Emoji, Twemoji Mozilla" (w/o the quotations marks). D} I've attached a screenshot w/ the result, It is marked w/ the red writing of font.name-list.emoji on it.

When i log into Instagram, Gmail, or Facebook i get a message that says "this browser no longer supported. Update to newer version" i am running 132.0.2. i have been using Firefox since version 0.7 and still prefer FF to all other browsers.

The screenshot function seems to have a bug. The function works as far as selecting "save full page" or save visible" but the image download never happens. Version is up to date and I have restarted but the issue persists.

I've noticed recently that some Unicode characters are not rendering properly on some websites. Specifically the Unicode characters for Mathematical Bold Capitals, though there may be others. I've noticed this issue on Twitch and GitHub. Screenshots for the repository sainnhe/everforest are attached along with the Inspector. Notice the characters do not appear properly on the webpage but are rendered just fine in Inspector. I also attached the screenshot for Unicode Mathematical Bold Capital E.

I am running Firefox version 132.0 on macOS Sequoia 15.0.1. The problem remains in Troubleshoot Mode. The problem does not appear in Chrome or Safari. The problem does not appear on my iPhone or Android tablet.

In posts with similar issues I've seen the suggestion to toggle "Allow pages to choose their own fonts", the issue does not respond to changing this setting (it is on in all the screenshots).

Is it possible to view the contents of two tabs simultaneously? I have been in many situations where it would be very helpful to view two different web pages side-by-side to more easily make comparisons. Opening a new window and viewing them side-by-side is similar but being able to pick two tabs to view in one browser would be a lot faster and easier to control.

Firefox updated to version 131.0 64 bit. Bill payment functions on my banking web site stopped working. I cleared cache and cookies and restarted PC but didn't fix it. I tried using Microsoft Edge and the banking web site worked as always. The bank IT person said it was a Firefox problem. Also, the site says not to block 3rd party cookies, enable cookie tracking and cross-site tracking. In Firefox, I made all changes to allow these things for this site but it still doesn't work. Looks like the latest Firefox update is causing a problem that always worked in the past, while trying to fix something else.

Hi,

When on this page:

https://addons.mozilla.org/en-US/firefox/addon/antffw/reviews/?page=9

even in safe mode, I don't see a button allowing to post a review.

I am of course logged in. What am I missing?

Hello,

There has been an upgrade of Firefox ESR to version 128.3 on Debian 12 bookworm.

Before the update, I could play videos, now I can't.

I precise I can play videos on Chromium, or with the video players.

I have libavcodec58, libavcodec-extra59, ffmpeg 5.1.6 packages installed.

There is an error in the console: Media resource xxx.webm could not be decoded. Specified “type” attribute of “video/mp4” is not supported. Load of media resource xxx.mp4 failed.

This command seems to indicate the session is X11 and not Wayland: ``` loginctl show-session 1 -p Type Type=x11 ```

This topic appears to show up a few times, but none of the solutions work for me (e.g. they were using A/V or "it just worked"). The error I get is also different.

This a pretty fresh install (migrating from Chrome so I'm currently re-logging into all my sites to ensure I can access everything I need.. and going through MFA hell heheheheh).

Everything is mostly fine, except for Synchrony Bank.

I go to login at https://auth.synchronybank.com/account/login, enter _any_ username or password (doesn't matter if I enter the right details or the wrong ones), and as soon as I click "sign in" I get an error page

Looking in developer console, the error reason given is NS_ERROR_NET_INTERRUPT while trying to POST to auth.synchronybank.com. Every so often I get PR_IO_TIMEOUT_ERROR but over 90% of the time it's NET_INTERRUPT.

This occurs also in private browsing and also in safe mode. I even created a new profile and tested it from there; same issue.

I've tried lots of things related to this (e.g. setting network.http.http3.enable to false), added the domain to the advanced tracking exception list, and I'm running out of ideas.

I can see traffic flowing to akamai but (it being https) I can't see what's inside the traffic. Could akamai be objecting to something in the content?

FWIW, I can login with Chrome on the same machine.
