Diễn đàn hỗ trợ Firefox

No help given - and no question asked. Quitting Firefox as there is no simple way to change fonts to a size that is readable. Going back to a browser where I can actually read the address bar, toolbar and all the other places where one has to have developer skills in order to make simple font changes. Tired of fighting crap.

On June 10, 2025, Windows installed an automatic update. This caused my Dell laptop to freeze every 2 to 3 minutes and I would reboot and start over. After 4 days of this trying every fix I could think of, I took it to the local computer repair shop. He said my video driver was bad. I think that was caused by an interaction with the Windows update. He fixed the video driver. Now the problem is I can increase the font size in Firefox fine, but I can't increase the tab and address bar sizes no matter what I do. I have been searching for days and trying everything suggested. Do I have to take it back to the repair shop or can you help me?

See the image below, how do I prevent that black box showing up and showing anyone who uses my device my sensitive data? How is this not a common setting to be changed?

Very insecure and Horrible to have on by default. Recently switched to firefox from chrome because of security concerns but stuff like this is making me want to go back, because HOW IS THIS SAFE AND SECURE?!?!?!?

I've typed in passwords in boxes that arent really password boxes, and firefox has suggested my own password in plain sight like in the image below.

Strongly recommend firefox to not make this default and make it an accessible setting to disable because I've leaked my sensitive information to online calls because of this. This urgently needs to be addressed as a security concern. At least have a cogwheel button next to the black box to quickly disable this setting. Very very disappointed.

The city that comes up on the 'weather' icon is wrong. I try to change it by following the instructions, but there is no drop down menu after I put in the correct zip code. There is no movement at all if I hit Enter or any other key. Please advise.

hi, i cant find an option to dismiss the new sidebar. it's pointless and i can switch all the buttons off, but now there is just an empty space at the side of my browser. very annoying. i hate the AI integration and i will not be recommending this browser to anyone in the future because of it. I have spent years convincing others to make the switch to firefox, but what's the point if it ends up just as toxic and useless as every other browser. disappointing.

when we open firefox, the language comes up in Germany, it whats to know if we want to translate to English but should come up in Englisg. we went into settings and made sure it was set to English

I want to add a dedicated search bar next to the address bar. When I search how to do this, I read: To add a separate search bar in the Firefox browser, navigate to Settings > Search and then click on "Add search bar in toolbar". This will place a dedicated search bar next to the address bar. But when I search for "Add search bar in toolbar", I get a message there are no results in Settings. I have Windows 10 laptop.

Updated recently from (I believe) 138.04 to 139.0.1, and immediately noticed that the size of font (and icons) had changed in the folders I have in the bookmark toolbar, that is they are much smaller and thus also less space between. Why this, and is it possible to change the size, without changing something else?

It's possible that many don't have folders in the toolbar and thus don't notice, but I have 2-3 apart from bookmarks.

I remember a change many versions ago that increased the space between entries in the bookmark menu, and also in the bookmark toolbar folders. That was too much and I found a setting [in config] that could be changed to decrease the space back then. (I haven't looked for that solution now, probably have some doc somewhere, and won't bother searching since this is different. Same with this case; I did some quick initial search but found next to nothing and older. BTW, this is one of the downsides of changes like these and similar; the day you have too move to another OS version, i.e. reinstall everything you also have to keep documentation of all these little changes, apart from all the other things you'll have to export or save.)

In Firefox Nightly, I am using vertical tabs - Whenever I close a pinned tab and reopen it, there is an annoying divider I have to manually increase in size. This is super annoying, is there a way to do that automatically or remove the divider? Thanks!

When accessing about:logins, Firefox prompts for system authentication (Primary password or master password). However, if the user cancels the prompt twice, the password manager still opens and displays all saved logins without authentication.

This behavior bypasses the intended security check and could pose a risk, especially in shared or public machines
