Multiple profiles are for different behaviour on the same, say Linux device, with different settings How does this interact with syncing? E.g., I want different settings, but the tabs should be synced?

I have several profiles which were created using About:Profiles. With the arrival of the new official "Profiles" function I had thought this would pick up my existing profiles and make switching between them easier.

It doesn't since the new official "Profiles" function doesn't see my existing profiles. Am I missing something here, or is the new official "Profiles" function somehow different than the previous, manual profiles system?

Os meus marcadores desapareceram com a criação de um perfil e não consigo encontrar a cópia de segurança.

Não usava nenhum perfil e, acidentalmente, cliquei na criação de um novo perfil. A partir daí foi irreversível e perdi TODOS os meus marcadores. Não encontro o backup, e não consigo recuperar os marcadores. Estes marcadores são muito importantes!!!!

Hello,

I use an online text-based website frequently at work, Firefox is my chosen browser for many reasons. One problem I am facing is that when I go to make text bold using the shortcut Ctrl+B, the bookmark bar appears on the side of my screen.

How can I disable this, as it does get in my way frequently, having to close the bar before I continue.

Hello

So a funny story happened today, I used CC cleaner to help clean my PC now I have it set up so it does not touch Mozilla in anyway yet after an update those settings got wiped and when I used the program it wiped out everything I had in Mozilla, history, saved passwords, tabs, EVERYTHING.

The last time I made a backup to my bookmarks was 6 months ago, a lot has changed since then, I tried to use the restore function however those also got wiped out, so I decided to use the old bookmarks, yet it doesn't work, for some reason it tells me that it doesn't have any bookmark data in the file yet Chrome can read and import the bookmarks from the file, if I try importing stuff from Chrome it also comes up empty, as an experiment I made a new export from Mozilla and tried to import it and got the same error. I still have 2 bookmarks and those can't be deleted no matter what I do, I kept trying to delete them however they are stuck there no matter what I try. This laptop is a new one I got on the cheap after my laptop had a problem with it's hard drive, I made the backup right before the switch.

Does anyone have any ideas about what exactly happened and keeps happening?

Firefox repeatedly crashes on my, multiple times a day. I'dc really like to NOT have to change my default browser to Chrome.

What happens is that Firefox freezes, and I get a white bar at the top telling me so. I get a popup box asking if I want to close Firefox or wait for it to respond. Waiting doesn't work, so I always have to close Firefox. When I reopen it, fortunately all m,y open tabs are retained, but it crashes again within minutes or seconds as soon as I click on anything.

There only thing that seems to work is a reboot of my PC. But the respite is short before Firefox crashes again.

I've disabled most plugins, but that hasn't helped. Is there a way to create an event log within Firefox that I can share with someone at Mozilla to help e debug the issue? It's got to be something local rather than Firefox itself; I can't imagine this is happening to most users.

Greetings,

For many years, I could easily access My most important Bookmarks, from a button, located to the right of the FireFox search bar. Over approx. the past ten days, not only did My "Add-ons" NoScript, & Malwarebytes, that were located further to the right of the "Bookmarks Button" disappear, but also the "Bookmarks Button".

I found my add-ons still listed via the Extensions-Add-ons tab, but,.... I could not move them back to my "Tool Bar", nor could I activate them. I tried many different ways to get NoScript & Malwarebytes back to the Tool Bar, & Truthfully, I can not remember how I got them returned to the Tool Bar.

Now here's the Major Problem,..... I had No Need to Access my "Bookmarks contained in the Main menu" during this time period, nor did I notice that the "Book Marks Button" was gone.

Several days ago, I had to retrieve Data contained in the "Book Mark Menu", & I was absolutely Shocked to see that it was gone! There is literally Eight Years of Personal Data, Research, & More in that "Book Mark Section".

I took off work, after completing a Job, since last thurs., & after doing a lot of Chaotic Searching, I found that somehow, for some reason, Firefox decided to move my Access to the Book Mark menu, to the "Library", without Any Notice Whatsoever!

I Absolutely do not care for where they are now, nor the fact, that I have to go through a longer process just to Access them.

How do I return My "Book Marks Button" back to the Firefox Tool Bar?

Hello and thank you for your time. I can not get my Discord to work it keeps telling me to update Firefox but it is already updated. This just applies to the sound and hearing I can type in text box. This has happened before.

Thank you for your help, Elizabeth

I noticed recently that my 'Add Shortcut' button has disappeared. I've been through other articles and they were of no help. I have 4 rows selected for shortcuts so theres no reason for it to be gone.

I am trying to use the print.always_print_silent entry to print PDF's. I added a print.printer_Mozilla_Save_to_PDF.print_to_filename entry with a string of file:///Users/Test/

If I append something like Test.pdf to the end of the string a file is created as expected in the expected directory. However, if I do not provide a filename explicitly, it does nothing.

Is there a way to use a variable such as the %t variable used in Headers / Footers to name the file dynamically? Otherwise I see no way to save multiple files to the directory in the fashion as it will overwrite the previous file with the explicit name.

Thank you for your help!

Hi Firefox team, I recently switched from Chrome to Firefox due to a recurring issue I noticed on my HP Omnibook laptop (productivity-focused, iGPU,). While watching YouTube videos in Chrome or Edge, I occasionally see a brief (0.1 second) black-and-white glitch near the top of the screen — but only when the video quality changes (e.g., auto-switching or manual resolution change). It never happens during regular browsing or local video playback. I’m testing Firefox now and wondering: - Does Firefox handle video stream transitions differently than Chromium-based browsers? - Is hardware acceleration in Firefox less prone to triggering such micro-glitches? - Any recommended settings or flags to optimize video playback stability in Firefox? - I was hoping to see an option to turn of AV1 video codec (if possible) I’m not gaming or doing heavy rendering — just casual productivity and media use. And I have switched on the default performance settings from my firefox browser setting. Would love to know if Firefox is better suited for this kind of smooth, glitch-free experience. Thanks in advance!

I've been using the "Show shortcut when selecting text" feature in Firefox, where clicking the AI ​​icon after selecting text gives me quick options like "Quiz me," "Explain this," etc.

But I've run into a issue: after a certain FireFox update, when I select text and pick one of those options, Firefox does open the Copilot AI sidebar (which I've set as my default), but it doesn't actually do anything after that—it just shows the Copilot new task screen without sending the selected text or performing the action.

I usually want spellchecks "English (United kingdom, large)" and "German (Germany)" active. Every few days to weeks it changes to a (single) random other language instead, like "German (Luxembourg)". Posts I've found elsewhere suggest changing display language (which should be unrelated and is already set to UK English), uninstalling all other dictionaries system-wide (which should not be necessary and is not acceptable), reinstalling Firefox entirely (but that's for cases where the correct dictionary was never selectable, I can select it, it just doesn't stay for long) or issues with syncing with other devices (but I don't change that setting on other devices, either). How do I stop spellcheck from changing and why does this even happen?

I started to have this problem within the last few days. Selecting "Open image in new tab" opens a new tab but displays a very small, pixel sized white rectangle and no image is displayed.

I dont have this issue in Chrome or DuckDuckGo browsers. I have deleted cached images, files, disabled all extensions and restarted my phone to no avail. I haven't found any relevant settings to check in my phone settings or in FFx but am I missing something? JW

Firefox V144.0.1 for Android 16 on Galaxy S24

Ok - My Englisch is not the yellow of the egg, But - Ich habe Probleme beim Aufräumen der Lesezeichen. (I have problems with organisation of the Bookmaks) Meine SideBar zeigt 2x den Bereich "Lesezeichen-Menü" - keine Ahnung warum. (My SideBar shows 2x the Area "Lesezeichen-Menü" - I don't know why.) Ich möche meine Lesezeichen in Ordnern organisieren (I try to organize my Bookmarks in "Folders" by theme) Aber - wenn ich die Einträge verschiebe, sind sie doppelt vorhanden. (But - if I move the entries, they appear double) Wenn ich einen der doppelten Einträge lösche, sind beide weg! (If I delete one of the double entries, they disappear both!)

Kann sein, dass ich nicht verstehe, wie das organisiert ist ... (Maybe, I don't understand the organization of the entries)

Bitte helfen Sie mir zu verstehen, wie ich das zu verstehen habe (Please help me to understand, how I should understand organization of the Bookmarks)

Ich bin kein Programmieren, habe keine Ahnung, wie ich Firefox einstellen muss ... (CSS???/JS???) (I am not a programmer, I have no idea, how to adjust Firefox 144.0 (64-Bit) - by CSS/JS)

Ich bin nur User - und mag den Chrome / Edge / Internet-Explorer nicht. (I'm only User - and I don't like Chrome / Edge / Internet-Explorer).

Bitte helfen Sie mir ... (Please help ...)

With best sunny wishes Ruth

I am getting sick and tired of ytube video 153 error messages on the latest releases of Firefox when trying to access a ytube video. I use Firefox on Linux (Ubuntu and Mint) with multiple profiles and it didn't used to be this way!!

Even clearing the profile cache and history has unpredictable effect. The web is full of questions to this very issue with no definitive fix. It appears Firefox is not clearing things out properly even though the profile settings are set to delete everything upon exit.

What is the fix?? (or is there one?) A very frustrated longtime user.
