Firefox Community Forum

Hello,

I have been testing all browsers I use (Firefox, Chrome, Edge) on Cloudflare Post-Quantum Key Agreement to verify PQC support. They all support the X25519MLKEM768 hybrid scheme (i.e. Cloudflare web page returns "You are using X25519MLKEM768 which is post-quantum secure").

The issue: When I run the test in Firefox multiple times by doing repeated hard refreshes (Ctrl+Shift+R), quite often the result is "You are using X25519 which is not post-quantum secure". Sometimes the very first run after opening Firefox gives the X25519 (failing) result. "Often" varies. Sometimes it's around 10 fails out of 50 tests, other times it's 1 out of 50. It seems random.

I have read that sometimes networking equipment or even ISPs can be the cause of PQC requests falling back to non-PQC due to the long keys in PQC, but I do not see this intermittent issue with Chrome or Edge on the same computer/network/ISP as Firefox. I have not seen a single failure so far on those two browsers. The only variable I am aware of is the web browser.

I also tried connecting to a cellular hotspot as well as disabling my Norton 360 firewall and the results are the same as above.

Looking for help to resolve this issue. Thanks.

I submitted a bug last to Bugzilla last Sep. that seems not yet to be assigned to anyone, and a bug two days ago that wasn't acknowledged. Is the Bugzilla site working? Should I be doing something else to report the bug?

When I search for something it shows up in English, but some text under the result is French as shown in the picture. I use latest Firefox with Google search engine, and I have all settings in Google set to English, And same for Firefox settings

Hi all,

After the last update the former Mozilla Test Pilot "Snooze Tabs" isn't working for me any more, I tell a tab to snooze and it just stays where it is. https://addons.mozilla.org/en-GB/firefox/addon/snoozetabs/

I've tried running with addons disabled and then running with addons active again and the behaviour is the same. It's the same behaviour whether I run from the toolbar or the context menu.

I'm presuming this problem is related to Firefox update mechanics. Any suggestions for how to get this working again please?

Cheers :)

This issue just started today.

I was attempting to watch a video on patreon, and normally I pop out the video so it is larger. This normally has no issues.

But today when I hit the button to pop it out, Firefox crashed.

Firefox then updated, so I thought maybe it was just because it needed to update.

I attempted this two more times with the same result. 

The first like I normally do where I start the video and then click the "pop out" button. Then the second time with the video paused. The minute I click the pop out option Firefox just crashes closed either way.

as is the text I read takes only 1/3 of the available width of the screen. In reading mode I can widen that, but many pages lose a lot in reading mode. How can I widen the text in normal mode?

I tried to remove the new 'profile'. I don't want it. now ALL my data, settings & bookmarks are GONE ! Help me revert to & restore the previous account settings !!!!!

When I open the history menu and search for any term, even a term that should return a bunch of results such as; http, google, search, results, <any keyword that I just searched> no results are EVER found. My history menu shows over a year of browsing data, but when I go to search it the search always returns NOTHING. It doesn't matter what I search in the history menu search bar, I always get no results. Yes, my history is being recorded, whenever I visit a site it is immediately visible in the history menu.

Stuff I already tried: Restarting firefox (duh!) Rebooting my computer Uninstalling my extensions Trying it in Privacy Mode Help>More Troublshooting information>Places Database>Verifty Integrity showed that my DB was "sane"

However, when I create a new profile and browse a few sites and search then the history search bar does work (in that profile). Based on that I think the issue is profile specific, but I didn't change any settings in my profile that I can think of. Any ideas what could be going on?

I was doing some work, when suddenly everything slowed, I checked my Activity Monitor, and it showed Firefox at nearly 20 Gigs of RAM & about 30% of CPU usage! I opened the Task Manager, and it only showed Firefox using 2 Gigs, and 25% of CPU. After a few minutes, the memory usage just as suddenly dropped down to the 2 Gigs as shown in Task Manager, and things seemed to be back to normal.

Why did this happen? I did nothing that would cause a spike, didn't open any new videos, or other high memory usage pages, or applications. I have seen FF showing a similar 20 Gigs of RAM usage, slowing everything down, several times recently, and wonder what could be causing these sudden spikes.

I have some names that pop up in an autofill dropdown when trying to input names. Some of them are misspelled and some are obsolete. How do i delete these? I've looked in Privacy and Settings and they are NOT present under "Addresses and more". Those are complete addresses with names. The ones i'm referring to are just names that pop up in an autofill drop down. These are names that i can't seem to find anywhere in Settings.

I came across another thread here that said try highlighting the name and Shift+Fn+Delete. This does not work

Thanks in advance.

Before the update, I could use "cmd+shift+[number]" to open a new container tab. Now, nothing works. "cmd+t" opens a tab with "no container", which is completely different.

I already tried going to "about:keyboard", but opening a new container tab isn't even listed as an option.

This has happened randomly on several different computers, both windows and ubuntu linux. It just now happened on my Win 11 computer. Was viewing the CNN news site and FF suddenly closed, without a "FF crashed..." message.When I clicked the icon to reopen it, it came up with the home page group of tabs instead of reopening the windows and tabs that were opened when it crashed. Worse, none of the previous months of history shows up and recently closed tabs and windows are both greyed out.

Is there a way of recovering the history of what I was working on at the time of the crash and what the hell is causing this? I am close to dumping FF and going with something else as this is highly annoying.

Gentlemen, isn't your browser using a lot of RAM? I've been freaking out about it in recent years. That's only with 25 tabs open!! Despite the fact that the system was installed just a day ago, without any tweaks!!!

I updated Firefox a few minutes ago and closed everything to let it finish. When I reopened it, all my bookmarks were gone. I checked the restore option in the Bookmarks menu, but only today's date was available, and clicking it did nothing. I found the bookmarkbackups folder in my profile directory, but there's only one file—859 bytes, which is basically empty. I'm signed into a Firefox account now, but my bookmarks aren't syncing from the server, which suggests they were never synced. Is there any way to recover them, or are they just gone?
