Collections bookmarks on the Firefox for Android homepage. I have Firefox sync. I have many regular bookmarks. Collections bookmarks from Android or obviously not available or synced with my Firefox for desktop. Are they synced or backed up at all anywhere? I cannot find them other than inside Collections. If I uninstall Firefox on my Android, Google Pixel phone and reinstall it will everything in the homepage collections be lost?

Hello, I am no longer able to sign into my Apple iCloud account and tools (Mail, Calendar, Notes, etc) through my Firefox browser. The problem started this past Friday, and it happening on both my home office and work laptops. When I switch to my Microsoft Edge browser on the same 2 laptops, I am able to sign-in to my iCloud account and tools without any difficulty. So it is not a problem on the Apple iCloud side. I am able to access my iCloud account and tools/apps from my iPhone and my iPad as always. It is only when I try to login from a Firefox browser window that I get a "Failed to Verify Your Identity" error message.

При заходе на сайте ya.ru и если на нём имеется строка с видео или поиск с алисой, то начинаются сильные фризы. Это ошибка именно в firefox 142, проверенно.

I use Firefox Android and Bitwarden Password Manager.

When I try to generate a passkey for some website Firefox asks me for the device to store the passkey. The only suitable Option is "This Device". When I tap it, i am asked for authentification (Fingerprint). After Authentification the website gives me a success message and the whole process is complete but the passkey isn't stored anywhere.

In every other browser on android I am asked for the entry in Bitwarden where the passkey should be stored. On windows this works with Firefox

Is it intended to work only when passkeys are stored in Firefox itself? At least a hint that it doesn't work with external Password Managers would be helpful - lost passkeys are a pain

Firefox doesn't have my new credit card account number. My old card was compromised and replaced with a new card and account number. But Firefox still maintains my old account number and it insists on auto-filling my cancelled card number when placing an order on line. How do I update my credit card information, or how do I delete the cancelled card number?

How to disable the auto-adding of shortcuts feature from history to home page? It's really annoying, when I want to change my pinned shortcuts, I have to delete all auto added shorcuts (Even when the items on the screen are finished, they keep appearing in front of me, and this takes a long time). It is a must feature I think.

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.

All of a sudden I am getting an "Invalid URL" error when trying to bookmark a website on Firefox mobile. I have tried pages with different extensions (.com, .org, .tv). I cleared the cache and restarted my phone. Did not work. I have the latest Firefox mobile 142.0.1 and a Samsung A25.

.: Hello. A couple of days ago Firefox stopped displaying thumbnails of YouTube videos. I tried YouTube on other browsers and the thumbnails appeared as usual. On Firefox, they've disappeared, but only on my Windows 10 computer. The YouTube thumbnails appear on Firefox on my MacBook. The attached graphic shows what it looks like on my Win 10 computer.

Any ideas on how to solve this would be greatly appreciated. I have also searched the Internet and YouTube for a solution, but was unable to find one that works.

Thank you.

I have the latest Firefox installed on Linux Mint. But in Firefox privacy settings there is no longer a way to choose browsers. It just says "Firefox is currently your default browser". But every time I do a search, it automatically search with Google. That never never happened until I installed latest Firefox. If Firefox is forcing me to use Google, that why do I need Firefox?? Please explain?

Thanks much for your time

Facebook simply isn't loading in Firefox anymore - it loads in Edge on my PC just fine and on my Mobile Android Browser .

I've tried disabling all extensions, and clearing cache and cookies, but Facebook still refuses to load and returns the message, attached.

I'm having issues using Firefox with the Facebook site. Groups are slow to load and sometimes the chat and notification windows take forever to load with shimmering panels or a wait cursor displayed. I've cleared the cache and deleted the cookie, but that didn't rectify the issue. I don't have a problem with Edge.

How do I remove a shortcut from the Firefox address bar? I understand that I can "uncheck search, address bar, and shortcuts" in Firefox settings, but I think this just hides them, so I wanted to solve the problem fundamentally and asked for advice. Please tell me how to completely remove shortcut URLs from the address bar.

Have been having an issue for the past month or two where if left in the background firefox will slowly start to eat up my available ram. I was using it like this perfectly fine for years previous to now.

I dont have this issue when I'm actively using it, only when I tab away from it and specifically its not on screen. Once I tab back to firefox the ram usage immediately dips back down to normal. I have tried many things to try and solve this like doing a clean install of firefox, getting rid of extensions, clearing my browser cache, closing all other apps to verify it was just firefox, clearing my history, turning on hardware acceleration. Nothing seems to help, im really at a loss and I don't understand what changed besides it being updated in the past couple of months.

My computer is fairly heavy duty and I have 16gb of ddr4 ram that again was working perfectly fine to run firefox before these past couple of months. As a result of this issue however if left in the background for too long on accident firefox uses up all my idle ram and starts causing other programs to not be able to run and has even crashed my computer previously when trying to run a program like clip studio paint.

I have noticed that while running the firefox task manager there is definitely some difference in memory usage when i tab back in after letting it be in the background so I have attached screenshots of the regular usage while tabbed in and the captured usage when i tab back in.

Any possible solution is welcome because I really enjoy using firefox and i dont want to have to switch browsers unless absolutely necessary.

Firefox claims does NOT save site/URL visit information while in Private Mode. And I thought that was true. However, I just discovered that Firefox DOES SAVE Private Mode URL/Site visits - in this specific place. I don't know how long the history will be saved - it looks like at least as long as the Window is open. I want to keep most of my open Private Tabs open - but want to Delete/Clear the ones I'm done with. I thought/understood that Private window/tab/visit info was not tracked/saved - and it's not saved in History, or Searchable. But it appears that this doesn't apply to the Recently Closed Tabs MenuItem. And there seems to be NO 'delete' or 'clear' option for this field. I can't find any reference to the subject in the Forum or Articles. The picture I've attached is NOT of the Recently Closed Tabs while in Private Browsing, but is the same MenuItem and field contents. Thanks for your interest. I'm hoping someone can help me figure out how to delete/clear this specific history.
