Firefox Community Forum

This is a followup to a previous post. I pinned a tab in firefox, and later deleted the webpage that was pinnned. I do not see a way to edit the pin, so I deleted it and created a new one with the new, updated webpage. I use the sync feature to keep all of my browser settings the same across three computers. I have tried multiple approaches to correct the problem. 1. turned off the sync and manually unpinned the tab, cleared the cache and browser history, checked to be sure I do not have the option to reload previous tabs turned on, booted in the mode that does not load any plugins, rebooted the computers 2. with sync turned off, after all of those steps, I opened the new page and pinned it on each computer. when I close the browser and reopen it on any computer, the original pinned tab returns. Turning the sync back on or re-enabling the option to sync tabs and history have no effect.

Is there a way, even if it´s within the configuration files, to change that pinned tab or block the old one from opening? Note that the website for the old and the new pinned tab is the same. the difference is the page itself. the old tab was [website].administration-landing. the new page is [website].admin-lp.

The is no reason why the old page, which no longer exists, continues to be pinned in the browser, but I can´t get rid of it.

Please help. Thanks.

Since the last update 155.01 I can't use Firefox as it freezes and hangs after 3 - 10 seconds. On Windows 10 , 64 bit. There seems a bug with the last update for Windows 10 users

Crash report: https://crash-stats.mozilla.org/report/index/c0455e29-69e9-4030-8b03-fdf430260909

Not sure the crash report is related to the issue.

The same issue happens to all of my 3 Windows 10 PCs since the update from today.

I have uninstalled Firefox and downloaded again, but same issue happens again.

I cleared the cache also but to no avail

How can I use Firefox again?

I accidentally deleted my old Firefox beta And I need to recover my settings bookmarks and data etc by logging in how do I do that immediately? I'm trying to recover my old Firefox beta account how can I do that immediately

i want to activate the build in VPN but it says i need to sign in. so i do that. then it says i need to click on it and it sends me back to the sing in and tells me to do it again...

One of the more particular habits I have retained after switching from Chrome to Firefox is putting things in Tab Groups. This works great on Chrome as groups are more-or-less visual, and don't make a mess once you've closed them. On Firefox, however, I've noticed one really annoying thing: tab groups are saved in a giant list. Part of my workflow results in making Tab Groups with the same name as some of my bookmarks. When using the address bar to go to the bookmark will result in the tab group of the same name being brought up. For various purposes, this is decidedly unhelpful. In addition, when using the "Recent Tab Groups" drop down, it is rather annoying to see an entire screen's worth of tab groups being saved, especially when they all have the same(ish) name.

Is there a way to disable this saving of tab group names (and contents)? Clearing it out manually gets very annoying.

I have reproduced a persistent Firefox/Linux emoji rendering issue in ChatGPT and found a small CSS workaround that fixes it.

Environment

Linux Firefox 155.0.1 The problem also reproduces in a completely fresh Firefox profile Noto Color Emoji is installed

Symptoms

In normal ChatGPT conversation text, some common emoji such as:

😄 😂 😀 😁 🙂 😊 🤣 ✅

render as monochrome or outline glyphs.

Other emoji such as:

🚀 🔥 ❤

may render correctly in the same message.

A particularly useful clue is that the same affected emoji render correctly inside ChatGPT code/copy boxes, while failing in ordinary response body text.

Firefox DevTools Fonts inspection showed ordinary fallback fonts including DejaVu Sans, FreeSans and Nimbus Sans being used alongside Noto Color Emoji.

Updating Firefox from 155.0 to 155.0.1 did not fix it, and neither did creating a completely fresh Firefox profile.

Diagnostic test

Running this in Firefox DevTools Console on chatgpt.com immediately fixes the affected emoji throughout the page:

document.documentElement.style.setProperty(

 "font-variant-emoji",
 "emoji",
 "important"

)

Permanent workaround

Using the Stylus extension, scoped only to chatgpt.com:

html {

   font-variant-emoji: emoji !important;

}

This survives a complete Firefox restart.

This appears to be a font/emoji-presentation interaction where some emoji-capable Unicode characters are being satisfied by ordinary monochrome text fonts before the colour emoji font is selected.

Mozilla Bug 1971053 describes closely related glyph-selection behaviour and mentions font-variant-emoji: emoji as a remedy: https://bugzilla.mozilla.org/show_bug.cgi?id=1971053

I am posting this both in case it helps other Linux/Firefox users and to ask whether this remaining behaviour on Firefox 155.0.1 is expected or should be tracked as a current Firefox/web-compatibility issue.

Firefox has recently started turning itself off. There is a failure message and it self-reports the issue. However it will do this without any website loaded, it just fails to continue running without a website being loaded. This happens everyday. The application will not continue to run just by being an open application with an empty about:newtab This is very frustrating.

Hi Mozilla Support Team,

We are experiencing a minor layout rendering issue on our online booking platform bookbustour when accessed via Firefox for Desktop.

Are there any specific Firefox CSS compatibility rules or extension settings we should adjust to optimize user performance?

Thanks for your assistance!

There is seriously something wrong with the way Firefox operates. There is nothing wrong with the following site so why am I seeing this message?

Be careful. Something doesn’t look right.

Firefox spotted a potentially serious security issue with news.sky.com. Someone pretending to be the site could try to steal things like credit card info, passwords, or emails.

news.sky.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site. Advanced What makes the site look dangerous?

The site is set up to allow only secure connections, but there’s a problem with the site’s certificate. It’s possible that a bad actor is trying to impersonate the site. Sites use certificates issued by a certificate authority to prove they’re really who they say they are. Firefox doesn’t trust this site because its certificate isn’t valid for news.sky.com. The certificate is only valid for: . What can you do about it?

I am a loyal firefox user and have used it for years. Security and features are great. I use Google docs constantly throughout the workday on my Mac and I am constantly having problems with Firefox. Google docs that I work in are constantly re-loading, incompletely downloading, going offline. I typically have 5-10 docs across the platform open at a time, and the problems are preventing me from working effectively. I have tried searching help forums and done the fixes suggested (repeatedly clearing cookies and cache, turning off protections, etc). Nothing works. Any ideas before I switch the Chrome (yuck)?

How do I make firefox my default browser when using search bar on task bar for windows 11. Although all my settings have the default browser as firefox microsoft, edge is what comes up when I use the taskbar search window.

I am unable to make or receive video calls in Facebook and WhatsApp. I used to be able to in Facebook. The message I get is that my browser doesn't support video calls. What is wrong?

This has happened on two different video sites already. While watching a video, it will go extremely dark and happens randomly. I also get a weird blank window frame sporadically. I've unjustly been reporting this to one of the video sites until I noticed the same thing on Youtube.

Accidentally told Fire-Fox to allow access to a website without two step authentication. I want to restore the ability to the website so the website requires a phone call to sign in.

Thanks in advance.
