Firefox 社群討論區

I am using Firefox 127 on Ubuntu.

When I press the Control key, I often lose focus in the window I am currently viewing. This is annoying as it prevents me from copy-pasting for example.

Sometimes the focus is back when I release Control, sometimes it is lost and I have to click again on the text field. It does not happen on all websites, for example support.mozilla.org works well, but it happens on duckduckgo or overleaf.

It does not seem to be the same as existing issues such as [the "show mouse when press Ctrl" of Ubuntu] (it is disabled) or an addon (the problem still happens in safe mode).

In case it is useful, when I press Control the tab bar background goes slightly darker, see attached images.

Thanks for your help :) Nicolas

I have been unable to find an email address, so I am turning to this forum to express my disgust at the incoming CEO's comments, namely "Firefox will remain our anchor. It will evolve into a modern AI browser and support a portfolio of new and trusted software additions."

Firefox's appeal as an alternative to Edge, Chrome, etc. is its respect for user privacy and control. Adopting AI tools into the browser itself is a betrayal of that respect, and will eliminate Firefox's advantages over rival browsers. If users want an AI browser, they already have that option. They want, instead, a browser that allows then to control their own experience and data. I beg the Mozilla foundation to actually do some research into your own market so you will learn that people hate LLM slop in their internet browsing.

Adopting AI tools will damage Mozilla's reputation as an organization worthy of respect. What's more, it will contribute to the further erosion of trust in information on the internet that AI has caused, because *LLMs lie and steal*. This is more than just a market mistake, this is an ethical mistake.

There is still time to change course. Do not follow Chrome and Edge into AI delusion.

Dark mode in Firefox has broken just now. The issue appears restricted to Firefox - all other elements in environment (Ubuntu/Cinnamon) appear to be operating correctly.

The elements at the top of the screen and some menu screens are now white rather than dark grey. Due to a neurological condition this causes near-instantaneous cluster migraines.

Is there a way I can fix this? Is there a way you can fix this? Is there a way to access the web without a browser? (eg through the text terminal)

Pandora tries to start, but it bounces from artist to artist without playing. Never had this happen before. Pandora suggests there is an overzealous ad blocker at work. Can you help?

Firefox always auto-fills in the wrong phone number. But I can't find a setting that contains my phone number. How do I change my phone number that Firefox auto-fills?

As title: after running updates, Firefox consistently crashes when launching.

To give more concrete details:

-Running on Linux, specifically KDE Fedora 42. Firefox was updated to 142 from 141, alongside various other updates. -When launching Firefox from any source (directly, through a link, through the terminal etc.), the only window that appears is the crash reporter. -This issue occurs when launching in safe mode. Removing and reinstalling Firefox, including deleting the entire .mozilla folder in Home at the same time does not resolve the issue. I am unable to test rolling Firefox back to 141. -When attempting to launch from the terminal (safe mode or otherwise), the following is output (personal info redacted):

restorecon: SELinux: Could not get canonical path for /home/[username]/.mozilla/firefox/*/gmp-widevinecdm/* restorecon: No such file or directory.

/usr/include/c++/15/array:210: constexpr std::array<_Tp, _Nm>::value_type& std::array<_Tp, _Nm>::operator[](size_type) [with _Tp = HeaderBarButtonType; long unsigned int _Nm = 3; reference = HeaderBarButtonType&; size_type = long unsigned int]: Assertion '__n < this->size()' failed.

Redirecting call to abort() to mozalloc_abort

[ExceptionHandler generates a minidump etc.]

Gtk-Message: [timestamp]: Failed to load module "appmenu-gtk-module"

(I would note that to the best of my knowledge I had not included a plugin for decoding widevine in my Firefox setup, and certainly the Firefox 141 instance on the device being used to write this post (same OS) does not include it) -The crash files in the .mozilla folder, meanwhile, consistently list a segfault at address 0x0.

Any advice on diagnosing/solving this issue would be greatly appreciated. Let me know if there's any other information that would be helpful.

If it would be more appropriate, I could report this through Mozilla's bugzilla instance, but given the issue seems to be very niche (Fedora's ABRT shows a total of 5 unique affected users in the last few days) I am unsure whether flagging this there would be appropriate.

latest versions of firefox (now at 140.0.1) keeps opening onto my 2nd monitor which is off - how to stop it doing it. Tried making new profile which works for awhile, but sooner or later they all bump it to the 2nd monitor and it never comes back - tried moving to primary and closing it there, but next time back on #2. Open 2nd window while first is on primary, and that goes to 2nd monitor...

woke up yesterday and suddenly my browser is largely non-functional.

When opening a file browsing window to upload or attach a file, where firefox would normally open my OS's file browser (Dolphin) it now opens a hideous firefox tab with extremely limited functionality (no file sort/ search/ open, or access to most of my system), and the Download toolbar is now completely broken. Clicking a file opens a little dialogue box that asks "Open with System Handler?" and does nothing upon clicking OK. Nothing also happens on clicking the folder icon to the right, which would normally open a Dolphin window with the file in question selected.

i cannot print any web page from Firefox. The print option only offers me the option to save as PDF. Firefox is not detecting either my Brother laser printer or my Epson inkjet printer. if i use the print using system dialogue option fire fox shows a printer screen which has a simple entry of line prntr. If that is selected nothing at all happens. Clearly Firefox cannot detect my printers. If I save the web pages to a PDF file then open that file I can then get the normal system printing options and print the page. But all that does is clutter up my file system with files I will only ever use once. This proves the problem is clearly in Firefox and in its inability to detect system printers. I have tried all the suggestions from the help screens to no avail. Is there any other means of sorting this print problem.

So I had logged into this Firefox account, but while I was, I forgot my password. I needed to enter the correct code from the email, but I lost the recovery key; I needed to enter in the 2FA code from my phone, then I could now change the password. When I logged in, boom, bookmarks gone. Passwords gone, and browsing history gone. I was waiting for it all to sync, but it had probably synced the deletion of everything possibly. I have no idea what happened, but I do not believe my account was compromised, because I did not get any emails about any new logins. If it is encrypted, how can I decrypt it so I can get my stuff back? Thanks.

When setting up 2fa. I scan the QR code. Enter the 6 digit pin generated by google authenticator. Download my backup codes and enter 1 when prompted then firefox says sync time and try again. I am running Ubuntu and have an android phone. Ubutu is set to automatic date. time and timezone. My phone is also set to automatic date&time. I have enabled seconds display on Ubuntu and phone the are synchronized to the second. I have tried this on multiple computers. Google authenticator works with all 9 other 2fa logins I use it for. I have tried many times and asked AI what I'm doing wrong Grok said I am not doing anything wrong after walking through the entire process. I have tried clearing cache and deleting cookies, signing out and back in without success. Please help I use firefox as my password manager and love it but want it to be as secure as possible.

thank you very much. Thomas

I have a local file I wish to view in firefox without starting a HTTP server (it's only docs for a crate I'm building) however Firefox is unable to open the file despite the file existing and having correct permissions. The file was in a separate mount (disk) to where Ffox is installed so I copied to to /tmp/ to remove that as a variable but still no joy..

➜ ~ file /tmp/index.html /tmp/index.html: HTML document, Unicode text, UTF-8 text, with very long lines (3556) ➜ ~ ls -la /tmp/index.html -rwxr-xr-x 1 ben ben 4208 Dec 30 14:04 /tmp/index.html

Am I missing some new setting which allows local file browsing using the good old 'file:///' protocol?

Thanks, Ben

F/Fox version: 146.0.1 (64-bit)

I just installed the browser and enabled Russian localization. Then I opened a page in English. A notification appeared with a suggestion to translate the page into another language. In the translator options, there is an option to select the language from which the translation will be made. There is Russian language there, but I chose English, it’s logical. And then comes the choice of the language into which the translation will be carried out, but there is no Russian language there. Why? How can I translate the page into Russian?

I am using Linux Mint with Firefox 127.0.2 (64-Bit)

In Preferences Applications, setting

 CSV-Dokument      to    open with firefox

opens edless new firefox Tabs - so I had to kill firefox. (setting CSV-Dokument to open with OpenOffice works fine. But this is not what I want.)

In Preferences Applications, I found further CSV types: application/csv-Typ CSV Document (application/text) CSV Document (octet/stream) CSV Document (application/x-download) Which applications should I use for them ?

I found the file "mimeTypes.rdf". However, I am not familiar with the syntax.

Is it possible to make a donation to Mozilla without providing so much personal information? I got a message on Firefox today asking for a donation, but when I tried to do that, I was asked for my home address. It's a general rule of internet marketing that people who use the internet would rather do anything than pay for something, so it's bad psychology to impose unnecessary conditions when you're asking for a donation. I don't have to provide my home address when I make donations to other organisations, so why does Mozilla need my home address? I apologize if this is the wrong place to ask this question, but I can't find anywhere else to ask it!

Thanks,

Shaun.

Hi Mozilla I hav got a problem with Firefox on Kubuntu 24.04.3. Everytime the computer is restarted Firefox crashes the first time it's started. That's not a big problem, starting Firefox again don't take long. But the problems is exceeding. If i start Firefox by clicking a link in a mail in Thunderbird. And Firefox has not yet been started, It crashes, but now it's also invaliding the Task bar on the screen where Firefox was started. Invaliding means that I cannot start apps from that screens taskbar, and the clock has stalled, none of the tools works etc. The only possibility solution I have been able to figure out, is restart (It's like going back to Win 98). Sometimes I am able to start a app from that invalid taskbar. But it's not the one app that i clicked on. Even though I can trigger it via Thunderbird, the invaliding of the taskbar will occur after a while. And I have to restart. I am not sure if this is the right place to post. But Firefox is always involved, but maybe Thunderbird or Ubuntu was the right place? Every time Firefox crashes there is send a crash report to Mozilla, but is has been going on for a while, so i guess that nobody is looking at the crash report. If I use Chromium instead of Firefox I don't see the problem.

Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to nrega.nic.in because this website requires a secure connection.

What can you do about it?

nrega.nic.in has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

Probably nothing, since it’s likely there’s a problem with the site itself.

I actively use keywords to search from the address bar, mainly g for google, gs for google scholar and w for wikipedia. Until a recent update (until last week, I think), pressing ctrl + L to go to the address bar would select all the text in the address bar, including the keyword, such that if I had made a google search by typing g and some query, I could immediately do a wikipedia search by typing w and some query.

Now, with an updated firefox (141.0.3, on xubuntu 24.04), the search engine from the previous search remains when I press ctrl + L, so I have to type backspace(s) to remove the search engine keyword, before typing a new keyword.

Is it possible to get the old behaviour back?
