I can't log in to certain sites even though they've been on my favourites list for years, i.e. bank account and grocery shopping. I can log in to them using Edge , so what's gone wrong with Firefox. Is the latest updates to blame ???

When I attempt to use Firefox autofill for address/credit card/etc, Linux will prompt for Root password. After entering root password, everything freezes. I have no access to mouse or keyboard and my entire OS become unresponsive. Besides the hangup, my firefox tabs randomly crash as well with the following bug tag: https://crash-stats.mozilla.org/report/index/3020d645-af46-4821-bbfc-e4d680250213. I don't know if the two are related, but both eventually lead my my OS freezing with only hard power down. Every time I try to use autofill, it freezes my OS. I can keep replicating the issue.

Hello,

I have encountered an issue on some websites where the Japanese text is using the font "Microsoft YaHei" when it should be using "Meiryo." Some examples are on the website bluesky, and bold text on Twitter such as in usernames.

I originally thought it was an issue on my end or in Windows, but when checking other programs and websites such as dengekionline and the non-bold text on Twitter it is using the correct font which I have confirmed via the inspector under the font section. When starting Firefox in safe mode it seems to use the correct font on the previously mentioned websites, so I disabled all my extensions and themes and this did not resolve the issue. I did a Firefox Refresh and this also did not resolve the issue.

I am not familiar with the intricacies on the Firefox about:config to really delve into the exact cause, so I ended up just reverting back to Firefox 134. On Firefox 134 with my same extensions previously the font is now back to Meiryo as it should be which leads me to believe it is something that was changed in Firefox 135. One thing I am considering is that the Japanese text is being recognized as Simplified Chinese by Firefox 135 as Simplified Chinese uses the Microsoft YaHei font as a default.

I have attached some photos that shows my Japanese font settings, and the same post by a user one on Firefox 135 which is using Microsoft YaHei and another on Firefox 134 which is using the correct Meiryo. I have also tried disabling the "Allow pages to choose their own fonts, instead of your selections above" and then restarting on 135, but this did not resolve the issue. Thank you for your consideration.

It seems certain sites are prone to fire popup tabs, with any click, right clicks included. I close them immediately and the second click acts normal, getting the nav result I was asking for. How to strength the popup blocking function to stop this distracting behavior? Thanks for any pointers. This may prevent me from staying on FF.

I have notbyte messages popping up with Firefox logo on them. How do i stop this happening? Tried to uninstall notbyte but cant find it. Can you assist. Thanks, John Dobson

I have been messing with my computer and this morning Firefox had ceased to function, and I will be looking for my extensive bookmark list here or on another drive.. I just feel that windows 11 is pernicious!!

On several web pages, when i try to log into the accounts i have on those websites or account creations, when i try to click "Continue" or "Log in" or what ever may be the case to actually finish the process, the button will not actuate. I have tried on Microsoft edge and it works with no notable issue.(It just is slow because its Edge. lol) I dont have an adblock going of or anything of the sort that appears to be blocking the operation. Please heeeeeeelp.

Internet page is having issues, I try to open my email account, mu Norton password account, my bank all keeps timing out wont let me use google, I cant use your webpage, tried to sign it it wont let me, 2 tries change password it states im locked out, what is going on

Hello to you up there ! I have Windows 11 - 23H2 up to date ! since 21/1/2025 each time I start Firefox (up to date 134.02 - 64 bits) I get a warning from Malwarebytes Browser Guard that blocks a outgoing request coming from Firefox via port 443 to the IP 82.221.136.1 ( = welcometothemachine.co …. what is that ?? analytics ? AI  ??) .... I am asking myself why is Firefox trying to go to that IP because I never did ask for something like that and how to delete the whole request every time now .... (CCleaner does nothing when used) ... bizarre bizarre behaviour yes ! Who can answer me. Can you please also answer me on geomar@scarlet.be because I would not like to miss the answer ? Thanks.

I use Firefox 134.0.2 (64-bit) on Ubuntu 24.04.

Some (not all) web sites show up only after a delay of exactly 30 seconds. The attached screenshot shows that this delay is due to DNS resolution. This behavior is reproducible by simply closing Firefox, opening it again and entering the same web site once more. Once this initial delay of 30 seconds for DNS resolving has passed the web site can be browsed normally.

Using Google Chrome, Opera or even the Tor Browser on the same system works without any significant delay. Also a DNS lookup from the console returns data almost immediately.

As the delay is always exactly 30 seconds this looks like some DNS resolver timeout only showing up when using Firefox.

Neither starting Firefox in Troubleshoot Mode nor (as often suggested) disabling IPV6 for DNS by setting network.dns.disableIPv6 to true did help.

Any idea how to fix this 30 seconds delay?

Many thanks for any help, Felix

I'm attempting to set up sync between my windows laptop and my new android phone. The phone has firefox loaded, allows me to pull up the 'sync and save your data' page, allows me to choose 'ready to scan' and presumably successfully scans the QR code displayed on the laptop (the laptop prompts me to approve the new device). Then the laptop indicates I need to wait to approve it on my phone, and the whole process stalls. The phone continues to display the mostly blank white screen with only the "moz://a" at the top and the spinning blue circle in the center. Eventually the whole thing seems to time out and I receive an error message on the laptop saying "websocket unexpectedly closed" and "device pairing failed".

My two hypotheses are that either still having my old phone (which is being retired to at-home use only, and I'd rather not de-sync) still synced is somehow interfering (seems unlikely), or that something about the new phone's software is interfering in the sync (seems unlikely and way out of my league in terms of troubleshooting around).

Help please?

After using the "recent browsing" menu in the top left corner of FF and opening certain websites from the "import tabs from other devices" menu it has completely broken a handful of websites on my PC entirely, even using other browsers.

The page will load but no content is displayed, no links or media, just a blank white page. This is consistent among these websites even among other browsers including Chrome and Edge.

I have uninstalled and reinstalled FF multiple times, cleared cache/history, hard PC resets, refreshed FF, Uninstalled and reinstalled every browser. The issue persists.

These websites still function perfectly fine on mobile FF and Chrome. I've exhausted website permissions, app permissions, etc. The issue still persists. These websites were functioning just minutes before I tried importing them from the other devices tabs. Something about that functionality has completely broken them on my PC.

In current version of firefox when attempting to log in to yahoo.com I get the error message from AT&T:

Something's gone wrong We may be having trouble with your connection. Connecting your device to Wi-Fi could help fix the issue or try again later. If you were using an app, close this page. Otherwise, start over.

No error when using edge or chrome.
