Firefox 社群討論區

Yesterday Firefox started crashing tabs on load of a handful of websites that are seemingly random, like Twitter and a few shopping site tabs I had open. It wasn't after a system update or anything, it just started happening while Firefox was already open and those tabs had already been open and loaded. I've tried clearing my cache, site data, reinstalling Firefox, and it still does it. Upon further investigation, it seems to be something regarding libfontconfig, and mostly specific to users of openSUSE Tumbleweed.

Every time I open Firefox, the checkbox next to "Opening links in tabs" always disappears, even though I've checked it in previous sessions. How can I make it permanent?

I use Firefox on the Linux Mint operating system.

Is anyone looking into this? I found an article that told me to remove some cash files and it seemed to fix the issue but it continues to reoccur. Some apps such as MS360 Outlook seem to trigger it, but if it was truly just a corrupt cache issue then cleaning the cash/profile once should have fixed the issue. Instead its become a constant pain in the *** and I'm tempted to find another browser. Seems very recent as well as I've never had issues with firefox before.

Ubuntu 24 Mozilla Firefox 151.0.3

With Duckduckgo set as search engine, if I type a search or go directly to duckduckgo search page the current tab crashes and the "Tab crash reporter" is displayed.

Google, Bing, etc work.

I have Duckduck privacy protections, privacy badger, and ublock origin all disabled for duckduckgo.

I signed in to https://accounts.firefox.com to sync Firefox on iPhone iOS 26 and got a sign in from an unexpected location.

Hello, I bank with Fifth Third a regional bank in Ohio. I travel a lot.illa not have a While on a trip I was unable to connect to my bank. One of the issues they mentioned is Firefox is not secure and thus will not interface with their system. My question is why does Mozilla not have a team which inter-acts with banks to insure that Firefox works properly and is considered safe, secure, and reliable? Thank you, Bill

I play https://crazyshooters.com/ and https://crazyshooters2.com/ a lot! But the game became laggy since Firefox 148 and my ping spikes up. Other browsers play fine. I am on Linux Mint if that helps. (147 and below run fine)

I have a Raspberry Pi 4b with a 64bit 4 core Arm CPU and 8GB ram. It is currently using Debian Trixie with the Xfce4 desktop.

I installed Firefox, and went through the setup. I made sure that in settings -> general the "Open links in tabs instead of new windows" is checked. I also set the about:config "browser.search.openintab" is set to true. My default search engine is DuckDuckGo.

Firefox will not open any search in a new tab. It opens them in the search results tab only. I have an x86-64 notebook and an x86-64 desktop running Xubuntu that are using the same settings, and they function properly.

Am I missing something? Is this a peculiarity to the arm version of Firefox? Is there another setting specific the Raspberry Pi or arm Firefox that I have to change?

Cheers!

I have lots (~100) of tabs open, distributed among windows and virtual desktops. Every now and then the laptop fan starts running wildly, and I identify a CPU hogging webpage in about:processes. How can I now switch to the open window/tab of that webpage to close or unload it? I would expect a click (or context menu item) within about:processes to bring me there. Currently I have to scan through all desktops/windows/tabs to find the page.

Hello everyone,

I would like to ask for clarification regarding the distribution of Firefox through third-party packaging methods.

As I understand it, Mozilla's trademarks and branding are protected, and in some cases official permission may be required to distribute Firefox under the Firefox name and branding.

Within the Ubuntu Touch community, there is a method called "Crackle" that can repackage existing applications and make them available as installable "Clickable" packages on the platform. One of the applications that has been repackaged in this way is Firefox.

However, this Firefox package is currently not available in the Ubuntu Touch software store because there is concern that distributing it may require explicit permission from Mozilla.

My question is therefore:

Does a project or community need Mozilla's permission to distribute a repackaged version of Firefox through a software store? If so, what would be the correct process for obtaining such permission? Alternatively, if the software is merely being repackaged to provide an installation method on another platform, without modifying Firefox itself, is additional permission still required?

We would appreciate any clarification regarding Mozilla's policies on redistribution, repackaging, and trademark usage in this context.

Thank you for your time and assistance.

bold text So I get the latest update to Firefox this morning, open a new tab, and all the tiles I had arraigned the way I wanted them no longer in that order, some are missing, some are duplicated 2-3 times. Why can't you guys quit with the window dressing BS and just make the browser stable. Why do we need to hunt for functions that were the same for many years that you decided needed to be changed? I remember when 'Settings' was on the new tab window instead of on the drop down menu in the tool bar.

My new tab tiles are a mess and I don't think I'll ever forgive you for that!

I'm using firefox in ubuntu. A couple of minutes ago Firefox crashed. I restarted to a completely new Firefox. All my tabs, extensions, saved passwords, etc. were gone. This happened to me a few weeks ago. That time I found a solution: find a back-up of the old profile and manually restore it. I tried to reproduce that solution this time, only to find that there are no back-ups at all of my previous session. Is there a solution to this problem?

The Alt-<number> keyboard shortcut is used to switch between tabs. However, the key event used to switch a tab seems to also propagate down to the content itself. This creates weird interactions:

- I switch to third tab - The web page running in the third tab actually uses Alt-3 to do something - After switching tabs the web page does something unexpected because the browser chrome didn't swallow the event during its tab-switching procedure.

The most irritating candidate seems to be XenForo forum software that uses Alt-<number> to go to different sections in its menubar. For example, alt-4 seems to open a search page and going there provides no new entry in the browser history. So, if I've tab-opened the forum to display new posts and then later I switch to it using Alt-4, it makes the content go to its search panel with no way to go back to new posts. Ironically, switching _away_ from the tab 4 does not register to the content so I can't even use the forum's own keyboard shortcuts to navigate back to new posts section or any other section. Having the forum in tab X will only ever let the forum see Alt-X and nothing else.

This all stems from the fact that Firefox lets the initial tab-switching key event through whereas I think it shouldn't. It maybe should if the corresponding tab is already active but it certainly shouldn't when a tab-switch actually occurs.

I've obviously disabled the content's capability to override keyboard shortcuts but it doesn't help in this because the content is not overriding anything: it seems to be just listening to a keyboard event that it shouldn't see.

Did I miss some option in about:config or do others see this as well?

I wanted to use the Firefox browser VPN to check what the price of a certain Patreon subscription is in another country, but when the VPN is on, the website still correctly identifies my current location and shows me the price in my current country's currency. Is this a limitation of the VPN, or did I not set it up correctly?

Non of the torproject.org site load on firefox they timeout. How do I access the torproject.org domains?

Does Firefox VPN not work with DNS over HTTPS set to Max Protection, and when using a custom provider?

With the VPN on and DNS over HTTPS set to Max Protection set to custom provider, no pages will load and I get an error screen/can't connect to proxy screen.

I am using Linux mint and have never encountered this problem before. It is not a login or password problem! I can't even open the site to get to that part! Connection timed out. Is there a simple fix like allowing AI enhancements? I found disabling them solved my shut down lag time and load time. I wonder what other sites won't work now.
