Firefox Community Forum

Hi,

I'm using Firefox 155.0.1 64bits, in Linux Mint Debian Edition 7, x11, XFCE4. I have a Belgian keyboard. I have noticed that the dead keys aren't working any more when typing text / messages from within Firefox. I don't have this problem in other browsers or applications.

I used xev (x11 utility) to check if the dead keys were working and tested a different keyboard, all work. I tried to start Firefox in safe mode or by starting Firefox from a terminal with the following commands: - env GTK_IM_MODULE=xim firefox - env GTK_IM_MODULE=ibus firefox

But nothing worked. The dead keys aren't working. The issue must come from Firefox for it is not an hardware issue (tried different keyboards) nor software (dead keys work in other applications).

Any idea to fix this ?

I've seen this on a few sites and it sounds like this person also experienced this. It happens on Linux and Window. I don't think it's a new bug/behavior.

I'll use vanguard.com as an example.

1. Visit investor.vanguard.com site. Click that you'd like to log on. 2. I'll be placed on a login.vanguard.com page that displays a Username field and a Password field. Because I've logged in before, those fields are yellow and filled in with the proper values. (In the case of the password field, it's all stars, but when I click to reveal the password, it's the correct password.) 3. Click on the "Log In". 4. The browser rerenders the page claiming that the userid or password is wrong.

But if I follow the above steps, but add a step:

2.5. I slightly edit both (one is not sufficient) fields, removing a character and putting it back in so the values are edited but not changed. As I do this the fields become white instead of yellow.

Now when I reach step (4), I'm actually logged in without complaints.

The underlying AJAX request is pretty cryptic, so I can't quickly spot/debug what happens at that level, but I assume the page is not passing the field values visible as yellow. on the page.

Am I misunderstanding how the yellow auto-fill works? (On most sites it works as I expected and no reediting the autofilled fields is necessary.)

Can this be fixed or should I put up with it?

I'm finding more and more sites no longer work using Firefox. I've confirmed all software is up to date, and tried different settings such as turning off ad , tracker and fingerprinting protections, but nothing works. Even sites at which I have an account have stopped working. Sometimes I can still log in to the account, on others I can't even do that. If I can log in, using the account for what it's intended such as searching for and saving lists of things or following links to saved items doesn't work. I value Firefox for it's security and privacy features, and being able to sync saved information in the account and across devices, but if a site won't all that benefit disappears.

I have issues discerning where each of my desktop windows are. To help with this I use gtk.css styling to add a border on all of my desktop windows. For some reason, Firefox does not draw this border.

Is there any way to apply a border around the Firefox window?

I was able to get a border around the navigation area of the browser by adding a userChrome.css file but I don't see any way to do the same thing for the whole window.

Can this be done in userChrome.css? Using gtk.css styling? Any other setting or file?

I am running Firefox 155.0.1 on Ubuntu Linux 26.04.1 LTS using the Gnome 50 desktop.

I am attempting to use your vpn. It says the I logged in successfully and that now all I have to do is turn it on. However, when I click the VPN button it displays the lets get started, I click on that button and it takes me back to a new successfully login screen and the loop continues, endlessly.

Hey folks and folkins.

I save all my passwords to my firefox.

I created a password for privileged access to my firefox at configuration time at some service. Recently (about half a year ago!) I created a new user at the same service (the same domain). The new login was used two times and is now stalled to log-in. It was simply a monitoring user.

Each time I visit the domain I get prompted with the monitoring user instead. I can not simply focus the username and select my previous user from the drop-down. Nor does firefox-password learn my preference (which is a good thing, I guess).

Nonetheless: I have to delete the username, write the first character of my user and then I can select my password. I find it cumbersome since I do this multiple times a day.

Imho there are privacy solutions which could be applied. I don't see any existing options in the UI.

Sincerly, Thomas

Each time I get my tiles arraigned the way I want them, firefox screws them up, re-arraigning them in ways I don't want, and adding ones I do not want and did not ask to be displayed on a new tab.

And while I'm at it, QUIT re-arraigning things in the settings. I used to be able to find passwords and other settings without having to search for them. All you're doing is arraignment the chairs on the Titanic! Each time I get used to particular settings, you guys come in and decide to screw things up, changing them in ways that few if anyone asked to have changed up. STOP IT!

I am using a local library and it comes to me that I find some activities that occur whilst working on my daily tasks and wonder, I would really like to run a diagnosis in my tasks and activities and check if there are no spams running me dry.

I get 'you browser cannot play this video" when I try to watch NFL Sunday Ticket on Youtube; what causes this? I use Linux Mint on my laptop.

I also have Opera browser installed; I get the same error using Opera.

Please help. Thanks.

Recent update nuked all my custom containers, and closed every page that was currently open within those containers (pretty devastating bug).

Now, I go to add sites to the new custom containers I made to replace the earlier ones. When I go Manage Containers > pick a custom container > "manage site list ..." and there is no list. Just a blank window.

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!

I've made a related feature request to include an option to force Firefox to give the option to autofill any arbitrary field as a credit card, address, whatever. This is because 9 times out of 10, Firefox either fails to recognize a field and doesn't offer an autofill option, or something else is going on. If I was able to right click on an empty field and select, "Fill from credit cards," this would solve my problem.

I inspected some of these elements and see that they seem to contain the correct type of markup, with the proper autocomplete="cc-number" attribute. So why is Firefox not recognizing that field? Why is it not popping up an option to autofill?

tl;dr: there is no option to autofill even on correctly marked-up forms. Nothing pops up. My credit cards are stored correctly, I'm logged in as the correct user, the feature works on *some* checkout forms, just not most of them.

edit: I don't know how to delete this. turns out this is a known bug on firefox on linux. Firefox cannot actually save payment info, but doesn't serve an error to the user. however in the console it will throw a NS_ERROR_ABORT error: "User canceled OS unlock entry" error when it tries to save. the one solution i looked at seemed way too complicated for me so i am simply going to give up and try to keep my cc closer to me and not get frustrated when it doesn't work.

I would like to make Firefox web browser to save automatically the "tab group" created.

The feature is already there by left clicking on the group and choose "save and close group". I would this to be automated as default behaviour at every attempt to close the last tab of the group, so the "tab group" never gets deleted by itself. Only deliberately left click on the tab group and choose "Delete group".

Thank you in advance for your time reading this. 🙇

Buenas. Me es imposible arrancar Firefox 155 en Debian 13. Cada vez que lo intento, un mensaje me dice: "Your Firefox profile cannot be loaded. It may be missing or inaccessible". En efecto, estuve tocando la configuración de perfiles para migrarlos desde una copia de seguridad y algo debí de hacer mal por despiste. Para aligerar, desinstalé completamente el programa con remove --purge / clean / autoclean / autoremove y lo volví a instalar de nuevo, pero el problema persiste. Es como si quedara algún rastro de la antigua instalación. Desinstalado de nuevo, intenté buscar la carpeta oculta de Mozilla Firefox, que eliminé; pero al instalar de nuevo el navegador, el problema persistía. ¿Qué sucede? ¿Alguien me puede echar un cable? Gracias y saludos.

Ever since the latest update i've noticed my firefox browser after using it for a while starts eating up all the ram until my computer freezes and needs to restart, i've heard this issue happen to others too but i am wondering if there are any ways to prevent it or will there be any updates to fix it?

I use my firefox on bazzite and have nothing else running in the background, after a while i watch the stats in my task manager and i see firefox using over 10GB of ram and climbing and have to shut it down before it freezes my pc

(can't show any screenshots because if i do then my pc would probably crash when trying to SS it while it has its problem)
