Some website can't display English content properly (shown as rubbish text as in figure provided), but if I copy those text and paste them else where (for example in a .txt file), they shown as English. I even disabled all of my plugins, but it still has the problem.

It won't have such a problem if I open the same web page via chromium-based browsers.

Just wondering what might be the cause?

Hi,

im getting unknown issuer on my thin-clients with a FF ESR 45.9.0. This FF is tied to the OS (Ubuntu 16.04) and the OS is the most recent compatible version for our version of the thin-clients. So yeah its super old and I'm not able to update any of this. There is no security.enterprise_roots.enabled option available. What would be the best way to solve this issue for ~400 clients. Thanks in Advance Regards Tekkion

I installed the Mail Link Enhancer add-on. It works, sort-of. The subject line and other fields included after the ? in the mailto address do not get filled in. Looking at the add-on info, the developer is Nick, but there is no contact info in the More Information section of the add-on profile. The add-on hasn't been updated since 2020, so I'm fairly certain that things changed since then and that's why it isn't working, but I'm no expert.

Hello! I'm trying to login on the developer hub, and it asks me to set up the 2FA, i follow the instructions, setting up the key that it gives me

After that I do verify the code and it success, but it is stuck on saying "Two-step authentication enabled" and it does not do anything

I try again to press the button, it times me out so I wait 15 minutes, after that it says again it has been enabled, but I does don't do anything else.

If I reload the page I start from 0 with another code, and same behavior.

When using Google authenticator the code is wrong both entering the code and scanning the qr.

What am I doing wrong? Thanks!

Hi lovely People, I try to setup 2FA on accounts.firefox.com with Authy on Android. In Step 1 the code generated from Authy is accepted.

But then, in step 3, when I try to paste in the just in step 2 provided backup activation code, it tells me it's wrong. Am I stupid? I just copied that key from step 2 ... I tried it many times now. Checked if my clipboard is working as expected, tried to delete the spaces in between... I used FF Standard and FF Developer Edition. My Authy is working elsewhere.

Any help? I searched the Forum, found some relating questions, but they never get answered. No one having the same issue?

I am an 86 y/o programmer with poor eyesight. I wrote my first program in 1960 and am learning html,javascript,php and sqlite. I frequently want my browser to 'forget' but in 150% enlargement the forget window doesn't fit on my screen and if i scroll down on the page i lose the popup, so i have to back out to windows (10) set my viewing to 100% and do it over. Suggestion: reduce the size of the pop-up and put the 'forget' button on the top. Are all the little icons necessary? I cant change any of them. And is the time frame necessary? i always choose '24 hrs'. IMO you only need a 'really?' pop-up to the forget button push and then wipe it all out. IMO Firefox is an amazingly good program! kudo's to all you Mozilla programmers! jim murray [email removed from public forum]

I already have a profile with all the extensions, passwords, bookmarks, etc., that I want, with FDE. I want to start using Nightly, but dislike the continual moving of passwords & bookmarks, so I just want to use Firefox Sync for this.

(1) Is Sync a good option for me here? I would use FDE & Nightly on the same laptop.

(2) If my plan is ok, what is the best way to start with a new Nightly profile (which I would then Sync)? I tried deleting my old Nightly profile, uninstalling Nightly, and then downloading & uninstalling Nightly again, but every time I do this (including a reboot after uninstalling), I get a profile cannot be loaded error message every time I try to start Nightly. I don't want to use an old profile with Nightly, because I do not want to sync old data at all.

Suggestions?

After restarting my pc, signed in on another windows account, which does not have Firefox installed. Then, signed in to my account, opened Firefox (Developer Edition 112.0b9 (64-bit)), however, all of the tabs, pinned tabs and history were gone. Can't restore from the menu, can't restore from the Profile folder, because files in it were overwritten when I signed in to my account (according to time modified). Anybody been in the same situation? Any advice? Thx

Hi, I use the Firefox Developer Edition for Windows Desktop (112.0b4 (64-bit) on daily basis. When I play the Udemy DRM content nothing goes wrong first and the browser loads the page well. But after some time passed I see that Firefox stops to load the page and the tab spinning infinitely. Pressing the realod button doesn't help. The only solution is to restart the browser. I use no-proxy setting. The refreshing of the browser didn't help either. I have configured the following options in the "about:config" but it didn't help as well: network.dns.disableIPv6 : true network.dns.disablePrefetch : true network.http.http3.enabled: false

Hi Firefox,

A link opens automatically in Firefox as soon as I turn on my PC. And that link redirect the page to some other link. This is happening from past several days. I have attached a SS of those links. What is the solution ? Is there a way in Firefox to block such links ? Early response appreciated.

If I want to do a 'clean' install of MS Windows - Windows 11 Pro v 22H2 (Build 22621.1485) - where are FF's sttings stored & how do I restore them after the re-install?

i used jeffersonscher to get all my tabs back from by old session but i restarted my pc and the session store jsonlz4 file got changed with a new one that didn't have all the tabs i previously had on it. When i did the restoring my jsonlz4 file was at 1:08am but when i accidentally restarted my pc it now is saying 2:31am and all the tabs that i have restored so far are on it but not the ones i haven't restored are not.

So is there a way to be able to get that old jsonlz4 file back so that i can restore all the tabs that i used to have.

Please help.

I just updated Firefox to 112.0. The "I-beam" shaped tool no longer appears on the toolbar, or anywhere on the Adobe page. So I can't get a text box to appear on the PDF or annotate the PDF in any way. Help! Thanks!

I'm on a HP Spectre 360 laptop, on Windows 11. Firefox 112.0.

Received this message thismorning while using my Ledger device:-

Something went wrong-U2F browser support is needed for Ledger. Please use Chrome, Opera or Firefox with a U2F extension. Also make sure you're on a HTTPS connection.

I have been playing a forum-based game for about six months now, via FireFox. I just got a new laptop, and it won't load past the "checking browser" page. It just tells me "This challenge page was accidentally cached by an intermediary and is no longer available."
