OS: Xubuntu 24.04.2 Apache: 2.4.58 Firefox 137.0.1 and earlier

In general Firefox is working. However, after every update, both major as well as point releases, where Firefox updates and then restarts itself, it almost always starts up and displays the homepage (local page on my machine) but is completely unresponsive. It will not load a locale or a remote page. I can kill all running firefox processes and then manually restart the browser -- with the same behavior. I have discovered that if I wait for around 10 minutes or so, then the browser starts working and continues to work just fine until the next update. Once past this initial update wait, I can kill/restart the browser, reboot, etc. and Firefox is responsive. It is only immediately after the updates that this problem occurs. This has been going on for at least the past six months or so, but is new behavior that didn't exist prior to that. This isn't a show-stopper, but it is very frustrating.

Any suggestions.

This isn't a constant issue for me, but occasionally the browser will suddenly break such that when I switch tabs, nothing actually updates until I do something like restore/maximise the window. I can still interact with the page itself, but whether using the mouse or keyboard shortcuts, changing, opening, or closing tabs, or even typing in the navigation bar, won't do anything until I resize the window again. I haven't been able to figure out any pattern to when this state triggers, but after it does, it doesn't clear up without closing and reopening the browser. I have recorded a video showing this behavior but I am unable to upload it here, and still images would not properly convey the issue.

Hello,

I've encountered a recurring issue with Firefox on Ubuntu where my master password is sporadically not recognized when typed using my external wireless keyboard. This problem does not occur consistently but is particularly frustrating when it does, as it forces me to switch to my laptop's keyboard for input. I'm certain the password is entered correctly; after multiple careful attempts (3-5 times), the issue persists, leading to unnecessary stress and inconvenience.

• • Environment:**

- **Operating System:** Latest version of Ubuntu - **Hardware:** Dell Latitude laptop with a Contour external wireless keyboard, connected through a Dell docking station. This setup is shared with another laptop (HP) via the docking station.

• • Observations:**

- The issue seems to occur sporadically and is not reproducible on demand, adding to the frustration. - It has happened notably on the first login attempt after the computer's first boot of the day. - On one occasion, the problem led me to change my master password under the mistaken belief it had been compromised.

• • Impact:**

This intermittent recognition issue disrupts my workflow and significantly affects my user experience with Firefox. The necessity to switch input methods and the initial misinterpretation of the problem as a security concern are particularly concerning.

I hope this detailed feedback assists in identifying and resolving the issue. Thank you for your attention to this matter Firefox.

Sincerely, Daniel

HI! I'm using Firefox 98 on Linux Ubuntu 20.04. after the last update I found several settings changed and I had to reset them, but there is one setting I can't manage. In the download preferences I set all the Microsoft Excel entries to "Always ask", but every time that I try to see an Excel file (no download, just open with ...), this is automatically downloaded. I definitively don't want to download it. How can I change this behavior? P.S.: I realized right now that there is the same problem with .docx files and I don't know how many others file types.

Firefox will no longer display the main window. I get an icon in my taskbar but the window is nowhere to be found. I've tried the tricks of maximizing it and moving it but neither works. I have found that if I locate the xulstore.json file it will work but only for a short time. Next time I start Firefox I get an icon but no window. Very frustrating!

The sulstore.json file contains nothing that suspicious:

``` {"chrome://browser/content/browser.xhtml":{"main-window":{"screenX":"2129","screenY":"777","width":"1280","height":"1040","sizemode":"maximized"},"sidebar-box":{"sidebarcommand":"","style":""},"sidebar-title":{"value":""}}} ```

If I start Firefox and right-click the icon, select maximize it's as if it's maximized covering all my windows but yet invisible. I can see my other windows but I cannot interact with them.

Deleting the xulstore.json file often fixes this but it breaks again shortly. What's the deal???

I'm a Chinese user, and all my firefox account in other devices( windows10, IOS) was login in page https://accounts.firefox.com.cn", but using firefox in ubuntu, it was redirect to https://accounts.firefox.com. Even i login with the same e-mail, the data can not be syn, and i have known the reason was there are two different server for Chinese.

But i need a way to syn data in Ubuntu, please tell me how to deal with that. 3Q !

Hi all, I'm having a lot of problems with Firefox crashing pretty often. Sometimes once or twice a day.

I most often see crashes in the middle of a Webex video conference for work. But Firefox sometimes goes down in other situations that I see no pattern in.

This is Ubuntu 20.04, Firefox 102.0. Unfortunately, it's a complex environment to debug.

First, when firefox goes down, it rarely leaves a crash report behind. So I'm not getting any direct evidence as to what is happening. Second, I run with uBlock active and it is very difficult to function in the browser without long enough for the crash to happen. Third, I typically have several hundred tabs open. I have a lot of memory (64G) in my machine, and the machine doesn't act like it's swapping, so I don't think I'm running out of memory.

Any help getting to the bottom of what's going on is welcome.

Firefox Browser 125.0.3, Flatpak Every few minutes, the mouse locks up on Ubuntu 23.10 and it only happens with I have Firefox open. I have have no extension, and history is turned off I have lived with this for months on multiple updates hoping for someone working on Firefox would figure out the issue and fix it.

This issue never happens to me on my windows PCs.

Any solutions? thanks Richard

I'm using Firefox 102 on Ubuntu Mate 20.04 (the vanilla one from apt), but I think I've experienced the same with a couple of previous versions too ...

So, I've sat in one Espresso House in Denmark; tried to connect to their public Wi-Fi with Firefox in private mode, captive portal went fine, and I was on the Internet. Apparently I had gotten a danish IP address there, since google.com thereafter was in danish.

Now, I sit in a different Espresso House, also in Denmark; however, here, captive portal does not work; in the sense that:

As shown on first screenshot, first I get "You must log in to this network before you can access the Internet.", and I get a "Open network login page" button.

I click on the "Open network login page" button, I can see browser wants to load http://detectportal.firefox.com/canonical.html - but in the end, I do not get the Espresso House login page, but instead I get a redirect to https://support.mozilla.org/en-US/kb/captive-portal , where the "You must log in to this network before you can access the Internet." still stands, but there is no more "Open network login page" button (as shown on the second screenshot)

If I restart the browser in this shop, I think I get the exactly same process - Espresso House wi-fi login page never gets shown, only the https://support.mozilla.org/en-US/kb/captive-portal ...

Strangely, at this point, I do get access to the internet through a browser - but google.com is then in swedish, which I guess means, that there is some sort of a VPN of that shop's wi-fi to Sweden. On the other hand, I don't get internet elsewhere on my computer - for instance, if I want to do `sudo apt update` from the command line, I get errors like "Clearsigned file isn't valid, got 'NOSPLIT' (does the network require authentication?)" - which is what I otherwise get in (the first mentioned) Espresso House, before I've connected to wi-fi via captive portal (once I connect to wi-fi via captive portal there, `sudo apt update` or any other network access from command line is fine).

(Note: my android phone in the same shop, does indeed show Espresso House Wi-Fi login prompt upon Wi-Fi connection, and I can login there fine).

Why does this happen, and how can I force Firefox to show me the actual captive portal so I can login to Wi-Fi - instead of redirecting me to https://support.mozilla.org/en-US/kb/captive-portal ?

Why cannot see Mozilla browser if I set it as a default browser?

Using Ubuntu: User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:134.0) Gecko/20100101 Firefox/134.0

How to reproduce the bug: Jump to the address bar, and then press shift, ctrol, alt or windows_start, you can see the address getting deleted. You can also see it in Google Sheets and Microsoft Excel Online, it just deletes the cell, or a selection of multiple cells. --Interestingly on Google Docs it doesn't delete but just move the cursor to the first character when a string is selected.

 It happens only once per mouse click, or focus change

What I expect: Shift, Control or any mod key should not delete content or move a cursor

Thanks!

Using either the SNAP or .deb versions of Firefox on Ubuntu 22.04 I am running into issues attaching files on remote systems. I can browse to mounted network drives and select files but when clicking open nothing is attached in any of my online email accounts. This also applies to the open dialog box. I have tried using the KDE File Picker as well as the GTK one but they both fail. This is not an issue for LibreOffice or other programs and greatly impacts the usefulness of Firefox.

Firefox browser crashes whenever uploading or downloading is tried. It seems website independent, and even a trial to start download from an email crashes the browser. Report IDs for some of the submitted crash reports:

I'm having really odd behavior using Firefox (linux) with Microsoft 365 web apps (outlook, word, excel, etc). Its happening various distros too. Is there a known issue at this time with FF and 365 web apps?

   Excel - cell content deletion on moving through cells.
   Word - line content deletion on hitting carriage return.
   Mail/Cal - Webapp not displaying content on double clicking emails or calendar events.

Found a few sporadic similar reports from users on various forums, but no official note that it was a known bug. Assuming it isn't widespread - anyone here have any anecdotal reports of similar issues. Seems to only affect the linux distro versions of FF.

This renders the web app sites unusable with Firefox so I have had to use another browser for these apps. As these apps are ubiquitous with work and productivity, it's rendering Firefox as a second-choice browser unfortunately. No one really enjoys having to "pick the right browser" for work or play.

Is there any way to resolve these issues? Hoping someone has some insight.

I have been using Firefox on Ubuntu for over 5 years over the past few months face book does not recognize me when I sign in. Face Book ask me to confirm it is me signing in as they think it is someone trying to hack my account. They send me a code to my email I put this into face book and they let me in to my account. They ask me to change my password this i tried they would not except it as they did not recognize my web site connection. They ask me to sign by another means IE mobile phone this I tried but Face Book did not except that either. I also got a notification from MY Heritage web site this is what they sent me.

We noticed that your My Heritage account was accessed just now from a new device or location: Firefox on Ubuntu | United Kingdom If it was you and you recently logged in from a new device or a new location, all is well and you can ignore this notification. Note that this notification may have been sent to you due to changes in your internet connection (e.g. a new IP address was assigned to you by your provider, or a recent use of a VPN service). Can anybody help please Thank you in advance Tony

For the past few months, the browser will no longer download any files. The only diagnostic that I can see is failed when the download is attempted. I have refreshed firefox and the problem remains. Chrome can download without any problems, but I used firefox for many years and wish to continue.
