MathJax formulas are not displayed correctly in Firefox browser windows, e.g. https://mail.google.com/mail/u/0/?ui=2&ik=96a0a80d2a&view=lg&permmsgid=msg-f%3A1748952987569305801&ser=1 Windows 10, Firefox 106.0.5 (64 bit) Thanks

Is there a toggle to turn off the purple theme in private windows? As an elderly person I find it hard to see things and it's quite irritating to say the least. This only started showing up in my Windows 10 and my linux systems in FF Version 106 and is also violating my preferences to have a totally blank page when a new private window is opened. Suggestions would be most appreciated.

Why have the English date format questions been archived without an adequate response? I, too, have Firefox English GB version and my Windows date format settings are dd/mm/yyyy but Firefox still uses the American format. This is not rocket science!! Please sort this out.

I am having an issue with Firefox snap on Lubuntu 22.10.

When I click on the Firefox account user image in the toolbar two error boxes open each time. I have attached an image of the error box.

Any ideas on where I could start with this?

After installing the new version 106.01, restoring recently closed windows in History doesn't work even though it is highlighted as being active, but nothing shows or happens when pointing at and clicking on "Recently Closed Tabs".

(I accidently closed one of my two windows and therefore lost all my tabs.) (I know I can restore the tabs one by one, but that will be a huge task.

So what can I do to restore my lost Firefox window?

Thanks in advance. Jens Giertsen Denmark

I've been unable to play twitter videos at all. For videos and audio posts on other sites, there's usually a delay for a couple seconds before it plays. I disabled all my add-ons and it made no difference. If I try to play 2 different things at once, both of them will chug if play at all.

Does anyone know what the cause might be? I tested videos and audio in another browser and they work fine.

Hi there!

I have a pretty frustrating issue with custom search engines. I use custom search engines all the time to look up words on a dictionary website. In cases where I need to look up something that is more than one word, I'm unable to use this feature because Firefox automatically adds '+' to encode spaces to the URL. since the website that I use does not know how to deal with that, I am unable to use this otherwise convenient feature in cases where my searches utilize spaces.

is this behavior adjustable in any way?

Dear All,

I am developer. I created the sign up form, when I am using Mozilla. I faced this error:

message: "Request aborted", name: "AxiosError", code: "ECONNABORTED", config: {…}, request: XMLHttpRequest }.

I checked it with Chrome and it works very well. It seems Mozilla has issue.

I can stored my data into database using Chrome. Therefore, I suggested you for developing purposes, never use Mozilla. Unless, you have solution.

Best,

Lately using Firefox, the audio is not syncing with video on Xfinity streaming. The audio seems to precede the video by about a half second or so. When I first load a video, it works properly, but I finally discovered that the delay occurs only after I mute the audio using the "PLAYING/MUTE TAB" button. Before muting, audio is in sync with video. But when I use it once to mute, after un-muting the audio is out of sync. The only way to get the audio back in sync with video is to reload the video source. This does not happen when viewing YouTube, nor does it happen with Xfinity when using the Chrome browser. I first noticed this about 2 months ago. Before that, I had been using Firefox for years to watch MSNBC in a minimized window, muting during commercials. Unmuting used to cause no problems. I'm wondering if this problem is unique to something in my installation or if it is a Firefox problem.

Today a Firefox box popped up to try some new colors (which was suppose to be a representation of my being or something like that). There were several colors to choose from so I tried it. The menu bar is now the color I chose. But suppose I want to change back to the standard FF color or some other color, how do I do that?

When I click to check for updates, it starts and the little wheel just goes around and around endlessly. This just started today; I've been able to check for updates every day without a problem. Is Firefox having a problem with checking updates?

i use the same add-ons on my desktop and laptop. i open my laptop and click on synchronize and later i open my desktop. two of these add-ons on the desktop have disappeared! this is not the first time. what can do i, how can install it to prevent it does not happen again?

I am changing my email addresses and will eventually delete the email address I initially opened my FF account with. Recently I added my new email address and set it as the primary email address for my FF account. I noticed thereafter that all my bookmarks were gone. I reverted my primary email address to the original one and all the bookmarks returned. How can I retain my bookmarks whilst updating my primary email address? Also, will other settings and features disappear when changing the primary email address? (I noticed that my add-ons remained the same.) Thanks.

Hi Today I updated Firefox to version 106.0 and I can't get rid of the "arrow button" from top right (screenshot attached - near the minimize button, I marked it). The function of this button is clear for me - tabs management. But I can manage my tabs without special button for it. I want to remove it. I tried right clicking on it, but the "remove from toolbar" option is unavailable. I tried to customize toolbar, but it won't work either (I can't take it from te toolbar).

How to remove this button?

I have two audio devices for audio output (speakers) on my PC. One is for music and the other is a Jabra device for conferences. When using Google Meet, only one of the devices is available to me (the music speakers). What is strange is that when I am using Zoom or Teams both devices are available and selectable.

Echo cancellation would be better if I could use the Jabra device for Google Meet calls.

I am using Firefox / Windows 11 (Version 10.0.22621 Build 22621).

Thanks in advance!

After the last update (106.0.1) Firefox no longer saves my open tabs after closing and then re-opening. Even though "Open previous windows and tabs" has been checked under the Startup section of General Settings. So I've now lost dozens of previously open tabs since this was unexpected.

Now, upon re-opening, I get a single empty tab. This seems to be a glitch that came with this recent update.

Dear Firefox Team, since updating, I've been enjoying the new Firefox View function. Sadly, as I'm using a few tweaks here and there (vertical tree tabs, modified chrome.css to remove horizontal tabs, etc.), its not visible at the place where it originally belongs. Because of that I'm searching for a way to include it in my workflow. To do this, I've made it my Homepage, and now, I'm trying to change it to my NewTab page as well. I find it more useful than clicking on a random website. I have tried to achieve this with addons and inside about:config; but as you know, "about:newtaburl" has been removed a long time ago.

Do you have an Idea how I could achieve this, or do you think it would be possible to create an option to this in a future release?

Thank you for reading my message, who knows maybe I can give you an Idea

Long story short, it's in the title. After the most-recent update, Firefox has been hanging whenever I type, and I'm right in the middle of typing a novel. The CPU usage spikes, according to the Firefox Task Manager, to 300% or MORE just from typing a few words. Even right now, typing this, the screen is sentences behind where I am in my typing. Took an entire minute for the page to catch up. On a single paragraph.

The hanging/lag does not occur when I navigate between pages, stream videos on Youtube or Netflix, or other things which should be about 100x more resource-intensive than typing a few sentences. And yet, that's all that does it.

There are no problems with lag when using Chrome, Discord, or other internet-based programs for typing. There are some issues with my word processor, Open Office Writer, but only when Firefox is open and running too, even though the two don't interact, to my knowledge.

I have followed every step on this page: https://support.mozilla.org/en-US/kb/firefox-hangs-or-not-responding This page: https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems And this page: https://support.mozilla.org/en-US/kb/firefox-uses-too-much-memory-or-cpu-resources beyond upgrading my computer, because it is absolutely ridiculous to consider doing that given the circumstances. It's only Firefox having the problem, after all.

In addition, I have reinstalled my keyboard driver, turned off cursor highlighting (it wasn't on, but I enabled it and disabled it again, just in case), and removed any delay in repeat keys in the keyboard config. No difference.

Honestly, I don't know that there's a community-based solution for this, but I'm willing to be wrong about that. I just want to make certain someone more official than myself is aware of the problem.

Thanks in advance, -Tyr
