I'm aware (e.g. https://support.mozilla.org/questions/1277401) of how to toggle whether the message window stays open (opening the next message) when an email is moved or deleted. But I would dearly love for it to happen only sometimes.

Specifically, when a new message comes in, I want to read it, usually move or delete it, then read the next new message, if there is one. But if the next message is an old one, I don't want to keep having it shown to me. I keep my inbox fairly tidy, but I'm getting sick of seeing that message from a year ago that doesn't have a better place to be.

So, after moving or deleting a message, if there is an adjacent unread message, keep the window open. Otherwise, close it.

If there's an unread message somewhere else in the folder, don't jump to that one. Trust that I've left it unread for a good reason, and don't want to now constantly get shown it, and also have to remember to mark is as unread again.

If it's easier to look for other unread emails based on dates, a few days (enough to span a long weekend, for example) would probably be enough, a week at the most. Or make that number user-configurable.

I have quite a few tags and quite a few message filters which are set to add tags. In the last few days, although the rule will automatically add a tag when I run it, it seems to be being deleted again almost immediately.

I have deleted several now obsolete message rules in case there was some kind of stack overflow problem, and likewise removed several obsolete tags, but it seems to be still happening. Is there a maximum number of permissible tags and/or a maximum number of permissible rules that invoke tagging?

This is a new phenomenon to me. I am on the latest stable release of Linux Ubuntu and Thunderbird 153.2.0esr (64-bit)

I'm on FF 154.0. The power went out here and when it came back and I booted the desktop computer something had changed in FF.

I used to see the active tab as green in the tab bar and yellow for the rest, but now they're all gray until I mouse over the bar and only then does it turn green/yellow.

I struggled with this for many hours trying many //active tab color// solutions I found in searches but nothing got it back to my old behavior.

So as a last resort I tried adding the Firefox Color extension, but when I click Add to Firefox it just turns into a throbber that never changes so it doesn't install. I'm stuck!

Frustrated!!

Is this a known fluke. In group with more than one email I see the excerpts and can easily deal with them (delete) but if there is only one in a group I can do nothing?

Up until recently (apologies, I do not know which version) when editing userContent.css on Debian 12 in the ' Developer Tools ' I could just use CTRL+S to save my changes and all was well.

Now it appears to have forgotten where it loaded in the first place, because (when using the shortcut or the 'save' link under the name on the left) it just opens the user's home folder at its root level or ' ~/ ' ...

Is this a bug that I should raise at bugzilla? Or has another bug fix messed this functionality up somewhat?

This is the ' mozilla-deb ' / ' Mozilla Firefox Debian Package ' currently at version 154.0 which is usually updated weekly.

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.

Well, I am in a real mess. Three days ago I lost the ability to access my favourite website. I CAN access the website in the Brave browser. The website owner has told me that it is not a problem with my account with them so it must be a Firefox issue. Before this happened I had been trying to move and delete files on my laptop and have got very confused about EVERYTHING. In that I had deleted my Firefox recovery folder(s). I have managed to move them back into my Home folder before they expire. Now I am being asked to enter my "password" to initiate the restore. But the several Firefox passwords in my laptop are not being accepted. How can I get a new password? If that is not possible do I have to delete my Firefox account? What is my best way to recover from this mess? Any advice is greatly appreciated.

Firefox security features warning on Linux doesn't explain what kind of file to add to apparmor.d/firefox-local. Is it a .txt file, or something else?

I am using thunderbird client on arch linux. I am trying to filter by adding "Reply-To" as a filter. If i look into the source of the email i am trying to filter (i get like 100s of spam messages and only the Reply To seems to be from the same domain in the end) the Reply-To appears in there.

Any idea how to fix that? The other rules work fine, this one only seems to not work

Pas moyen d'ouvrir Firefox depuis une clé usb de démarage. On me demande un code par courriel que je ne peux pas ouvrir. Je suis bloqué car je tombe toujours sur le Bios quand je veux avoir accès à mon ordinateur. Commenr m'en sortir De l'aide SVP Merci

I see this in abrt:

Is this normal behavior for Firerfox 155.0 on Fedora 44 KDE-Plasma 6.7?

I have a problem to add my mail account on Soverin.com to Thunderbird under Linux Mint. If I have created the additional e-mail in Thunderbird and I put there a right passord it is not possible to connect Soverin server.

I recently made a backup (via the option under Account and sync in the settings), as I was switching to a new OS. Unfortunately, when selecting the backup in the new OS, I am greeted with the error message:

This file isn’t working. Try picking a different file.

According to this, my file is corrupted. Is there anything I can do to fix this, or have I just lost all my data? I no longer have access to the profile files in the original OS.

I've been relying on backup/recovery from backup because firefox now deletes my profile/session every time it does a meaningful update (several times a month).

Now, one stupid/broken thing is that I have to re-enable backup every time I restore my profile/session (this setting, backup ON, should be included in the profile/session!).

The second broken thing is that now I can't re-enable backup today, after yesterday's update.

I can fakely turn backup ON, but when I click "backup now", I always get "Hmm, there was a problem backing up. Learn more"

Learn more has no useful information. Waiting a few minutes, like it suggests, does nothing. Now, I'm going to get my profile deleted the next time firefox updates, and I won't even be able to restore from backup.

Finally, whoever's in charge of this feature needs to learn English. Log in is a verb, login is a noun and an adjective. Similarly, back up is a verb, backup is a noun and and adjective. You can't "backup" your profile. You BACK UP your profile. A backup is a noun. You can't do nouns. You do verbs. I back up my profile. I back up (verb) the backup (noun) in a backup (adjective) file.

I run normal firefox on linux. Fully up-to-date. Every time I quit the app, it reverts to a version of my profile from a month ago, and loads all the tabs I had open then, and then receives all the tabs that I sent to the device in the interim (~1 month). As I speak, it just caught the 60 or 70 tabs in this window.

I tried changing the name of my profile folder to randomstring.defaultOLD and changed one of the backups to randomstring.default. This didn't change the behavior. I'm still stuck in the loop. I saved my tabs with onetab, because firefox isn't remembering my session anymore. I thought it was something to do with updates, like it only loses its mind upon updates, but that's not true. It thinks it's updating firefox EVERY TIME, because the one time it's loading to 1 month ago it was updating, but I'm 100% sure there are no updates to firefox in my linux. It's just hallucinating.

The articles on restoring from backup are outdated. They say to use an html file. There is no html file. It's just folders for profiles, not html files. HELP!
