Diễn đàn hỗ trợ Firefox

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The articles on restoring from backup are outdated.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!

My spell check generally doesn't work, but occasionally comes back to life, I have tried the about config, and change value to 2, I have tried uploading dictionary, and making sure check as I type is ticked, but the setting on config seems to keep reverting to 1, and I'm sure if I have successfully uploaded a dictionary, I clicked on language pack, Ironically while I'm typing this, my spell check is actively involved.

I tried updating Firefox or testing for the crash in Troubleshoot Mode, but it keeps crashing every minutes or so. Here is the report ID bp-67065b07-74d6-417e-b7de-caf500260906

Hello, this is the basic problem:

The short version is that there is a problem with Firefox not interacting with the scrub bar and volume bar. (all other controls work fine) We know it's a Firefox thing because everything works with Brave. (or an interaction between Firefox and the OS at least, Firefox is heavily involved)

There is more detail and we have done some work on it here: CashyOS forum post

You can use the Firefox manifesto V0.2. video for an example, as it displays all the above problems for me.

I can get you guys whatever other data might be needed, but I kinda need an idea where to look to try and fix this, as all the other posts I have managed to find don't seem to have similar enough issues to work.

I can't see bookmarks on the RH menu but only on the LH when I click 'manage bookmarks. How do I move the bookmark folders so that they appear on the RH. This happened at the last software update.

I’m trying to find the backend email address configured for a website’s contact form using Inspect Element/Developer Tools. I’ve checked the page source and searched through the available HTML, but I’m unable to locate the email address or identify where the form submissions are being sent.

Could someone please guide me on where I should look or which files/settings I should check to find the form’s destination email?

Hi everyone,

I'm facing an issue with website screen responsiveness in Mozilla Firefox. A site that is supposed to be fully responsive and mobile-friendly displays properly on my 24" desktop monitor (photos, alignment, and overall design look fine). However, when opening the exact same URL in Firefox on a 13" laptop screen or a mobile device, the visual design breaks—layouts overlap and images get distorted.

Has anyone encountered this issue in Firefox with certain display scales or viewport media queries? Is there a known fix or setting in Firefox (or layout tweak) to resolve this layout breakdown on smaller screens? Any advice or troubleshooting steps would be greatly appreciated!

After recent Firefox update in v 154, saved passwords do not auto-fill in all websites. Actually, not even the username is loaded. I tried to open in troubleshoot mode and didn't work too. I tried to log out and re-login and fixed for a while only. Then same issue re-occurred. In websites where I have multiple accounts it's too hard to find the proper one. In the Settings > Passwords everything is enabled.

In previous versions of FFox when a file was being downloaded, a file download window opened for each file. Is that feature completely gone or is there still a way to open a window for each file?

When I select Photos from menu (top right bars), I get Google message that there is a problem with my cookie settings and I need to enable them. I haven't changed them.

I'm only noticing it when using Facebook, but an Internet search says the setting is in my browser. I've now checked my Firefox settings and see nothing about it. Would appreciate help.

I have always used Firefox to access my account with Spectrum.net, until the past few days, when my login has been rejected, repeatedly. Talking to a Spectrum tech rep, she told me to try to log in using Chrome. I tried it, and had no trouble changing my password and then logging in to my account. The tech rep concluded that the problem therefore lies with Firefox. Does Firefox need to be re-set somehow? Thanks! Hollis Barber

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.

Tengo problemas al navegar por internet usando Firefox. Algunas páginas web no cargan correctamente o tardan demasiado tiempo en abrirse. Pasos que ya intenté: Borré el caché y las cookies, y el problema continúa.

I have noticed several automatic updates in the last several days.

Yesterday, I started my Lenovo laptop and clicked on Firefox to start my business day. Clicked on the icon. Nothing opened on my screen. Each time I clicked, a thumbnail would open (see attached image).

I can right click on the icon. I tried open a new window. Nothing. I tried open private browser. Icon opened, I can see thumbnail, but it did not open either.

I tried to download new Firefox. Same. I tried to delete Firefox from Installed Apps in settings. Then I was asked if I wanted to Refresh Firefox instead of deleting. It saved my Firefox files. Thank you. I followed the steps. Firefox worked throughout the day.

This morning I tried to open Firefox...nothing except thumbnails like in the photo.

Photo has version date for Firefox. Dated yesterday 9.9.2026.

Appreciate your help.

All I have access to is right click on Firefox icon in my tray. I cannot see any settings.

This started happening in the past 2 days. I would navigate through a page or a forum to an article or listing that I want to read. when I go to the link, the page goes into reader mode, refreshes rapidly, and usually crashes to a previous screen. It’s been happening on almost every website I go to. In addition, if I press the shift key, the debug window opens and closes. Things I’ve tried:

It’s only Firefox, I don’t get this behavior in chrome, brave, or duckduck I’ve disabled extensions, and tried troubleshooter mode I’ve disabled hardware acceleration I’ve cleared cache I’ve wiped Firefox from my system and did a clean install I’ve wiped Firefox and installed an older version

None of these have worked. I’d like to keep Firefox on my pc because I’ve used it since the beginning. Any help would be appreciated.

We use the Deepl site for translations and it won't load in Firefox without asking the "verify you are human" questions every single time. The Deeple site does not require this authentication in Chrome but we hate Chrome and want to stick with Firefox. We just have the standard security settings in Firefox, only use Windows Firewall and our Express VPN is not switched on; our IP location is showing correctly. Firefox is up to date.
