Firefox Support Forum

I was trying to install a lot of Firefox themes from Firefox Add-ons and when I checked the themes that I had installed, it didn't show all of them.

Is there a limit number themes that could be installed for Firefox?

When watching youtube or even doing a little task with only one tab the cpu usage from a specific firefox process goes upto 90%. And I have did everything that was given in the following troubleshoot method "https://support.mozilla.org/en-US/kb/firefox-uses-too-much-memory-or-cpu-resources" but still the same result. I tried with troubleshoot mode on with disabling all extensions but the cpu usage was still high. I have also checked with firefox's own task manager tool but there wasn't a single process that was using full cpu. I'll be attaching all screenshots below.

I'm having problems streaming live video on srf.ch (Swiss public television). The whole tab becomes unusable after streaming for a few minutes. Playback just stops and it's impossible to reload or navigate to a different address using the same tab.

This happens with a clean profile using two different computers with very different hardware. I'm able to reproduce it using Firefox 111 and 112, but not with Firefox 110. It doesn't happen in Chrome.

Unfortunately, I couldn't report it as a web compatibility bug. The person reviewing the issue wasn't able to access the streams due to geoblocking (VPN doesn't help). They asked me to provide additional information such as console logs. But even the console stops working when the problem occurs and there are no error messages before that.

Is there anything else I could try to help diagnosing this issue or is it a lost case?

I've been noticing for a while that Youtube chapters were very hard to read if they were displaying over a white background. I thought this was just a Youtube issue but then I decided to boot up Edge and Brave to see if the issue still persisted. It doesn't. What happens in those browsers is that there is that the bottom part of the video is darkened just enough so that when the chapters are displayed there is enough contrast to read them. In Firefox this overlay cuts out before it reaches the chapters making them very difficult to read. I tried in Troubleshoot Mode and the issue persists.

I've linked pictures that demonstrate the difference.

Hey team! After my organization restricted GitHub access to a specific IP ranges (from inside company VPN) I cannot access GitHub Organization repositories through Firefox Developer Edition, though VPN works and I am signed in. I can see the following error: `Access forbidden from this IP address` together with incorrect IP address displayed.

Also worth mentioning that through Google Chrome I can access my company GitHub pages perfectly.

Can you please help?

Hello, so i want to apply SF mono font to my codeblocks but they are instead applying lucida console font, how will i fix this? My monospace font is currently set to "SFMono Nerd Font"

Getting 2 error messages:

This page isn't available right now This may be because of a technical error that we're working to get fixed. Try reloading this page. [button]Reload Page

Your Request Couldn't be Processed There was a problem with this request. We're working on getting it fixed as soon as we can. [button]OK

The second message happens sporadically when I click on Notifications. I can't do anything but quit FireFox and try again sometimes it works, sometimes it doesn't and I have to wait a while, sometimes as long as a day to get it working again. The first message occurs when clicking on a link. After which I get the second message.

This is extremely frustrating because of the randomness I think it is a FaceBook issue but have gotten no response from them. I'm trying to cover all the bases by asking the FireFox community if anyone has run into this and if there is a solution.

Many THANKS,

Joe B

I had Firefox account, which is used to community translation contribution (not bookmark, password or other data) and last month I lost my 2FA app and now without 2FA for this account, so try to use 'backup authentication code' method. - Used 'backup authentication code', which I had 8 of 10 letters/digits code generated (on 16 May 2019 and only email), it is not working - I am able to change the password, but still asking 6 digit code, which I don't have - I have secondary email, but can't be used to login as per documentation.

I have two questions - Why 'backup authentication code' is not working? how to verify if backup method is working or not when it needed? - Can I request to delete my account to create again as I have secondary email as I can verify identity and ownership of that account with secondary email?

Hello, I wanted to report this problem. So, this problem occurs all the time. If I leave the browser for like 5 mins, firefox couldn't load a new page/change to another webpage. I'd have to wait for firefox to fail load (until a error page come up or until the loading icon dissappear) then i could load a new page. It's kinda annoying tho.

I'd be glad to see a response.

Regards Thanks

Hi All!

Every time I install Firefox on a computer and log in to sync, the pinned shortcuts sync happens the wrong way. So the new installation gets a collection of relatively random shortcuts for websites I visit, plus a few of the default ones (with the search option/magnifying glass feature integrated) for sites I don't really visit, then this is synced on all other computers. I have to go manually on one of the others and redo the pinned shortcuts, then this syncs everywhere.

I've had the issue for years. I work from multiple computers so the sync feature is invaluable but also extremely annoying that I have to redo a couple of dozens pinned shortcuts every time I install and sync a new Firefox. The rest of the sync works fine (bookmarks, etc.).

Am I doing something wrong or is Firefox unable to properly sync pinned shortcuts? I imagine I can migrate the profiles over all the time but the benefit of the sync feature is that it's seamless so I'd rather use that if possible.

Thank you!

So im trying to change firefox developer's Ui and page display languanges into english. But firefox ins't showing the language options. And the ones that are there ins't working.

Hello, While I do in fact the like the amount of customization that's available while using the firefox browser, there are certain aspects of viewing certain webpages that I'd like to improve upon. Certain different chromium based modern windows browsers have different experimental flag settings that let you choose different background settings instead of all or none like firefox seems to do. I'm enclosing a couple screenshot's of what I'm referring to when I'm using the microsoft edge chromium based browser for your reference. Currently I'm using the following add-on to at least temporarily help me with my current issue: https://github.com/m-khvoinitsky/dark-background-light-text-extension. In the attached image while using firefox while viewing the msnbc webpage, currently the displayed colors are totally out of balance. Thanks in advance for any suggestions and help that gets provided to me. David

I use Firefox on 3 devices: - a PC at home (Win 10, FF standard instalation), - an Android phone (Xiaomi Mi 9T) - a PC at work (Win7) with the Firefox portable version.

I have the latest, stable, up-to-date versions of Firefox on all my devices.

The problem is when I save a bookmark on one of the computers at work or at home, and then the devices synchronize. Bookmarks between computers do not remember their position in the bookmark folders and are saved in the main folder.

I have already performed all the steps based on the instructions in this article, but the problem persists. ([https://support.mozilla.org/en-US/que.../1270667])

Hello, I would like to use the search function in the tab again. How can I adjust this? At the moment it is so that when you enter it it appears right above in the link line (see picture). I would like it to be in the search below, directly in the tab. Before version 88 this was possible. Why was it removed?

hallo, ich möchte wieder im Tab die Suchfunktion nutzen. Wie kann ich dies einstellen? Zur Zeit ist es so, daß bei einer Eingabe es gleich oben in der Linkzeile erscheint (siehe Bild) Dabei möchte ich es unten in der Suche, direkt im Tab haben. Vor Version 88 war das möglich. Warum wurde es entfernt?

Considering you update nearly every day, the dumbest thing you've done is change the "view photo" in the right mouse button to "open photo in a new tab". Why did you do this dumb thing. We all look at photos, and you made it inconvenient. Dumb Firefox code writers....

I am using an offline web page as my default firefox home page and all was going well until I enabled sync. Now when I boot up firefox two things happen. It changes the address for my home page file to a folder NOT on this computer (the desk top) and won't retain the address I need for that folder.

I have just tried editing the bookmark for page. At the moment it seems to be working but I think sync is causing this issue and wonder if there is a fix for it?

Thank you.

My Firefox can't play any video on any websites. Youtube video keeps on buffering forever and I can't click on the play button. But preview images still shows up when I hover the mouse over video bar. This happened after I updated to latest FF version

I've tried every solutions provided by Mozilla Support: clear caches, disable extensions, uncheck hardware acceleration,.... you name it I've tried it all. Other browsers are just fine, but since FF is my main browser for work I don't want to switch to another one just for music or video.

Thank you for your support.

Firefox 90b8 (64 bit). Note: I had previously been using 32-bit and it would crash once or more per day WITH crash files, many of which were (I think) submitted to you. My PC may be a factor: It's a "new old stock" (vintage 2016 or so) Pipo X9S. This model has 4 GB RAM and a 64 GB EMMC "disk." All disk operations are pathetically slow and I suspect this a factor in the poor performance.

I'd been hoping to see if the 64-bit build works better or could provide crash files. Clearly there's still something broken, but why no crash message/file?

The PC itself has been checked as well as I can. Latest win10 with all updates. Chkdsk /F finds no errors. I even downloaded and ran MEMTEST86 -- no problems there.

Firefox's "Use" is typically streaming music (SoundCloud) but many crashes happen when also doing normal web browsing in a 2nd tab.

Can someone help me to set up crash messages and reporting? Thank you.

Hi I am currently creating a Firefox plugin and I am trying to grab the data from the secure website certification to use and display to the user is this possible?

Basically, what it says in the title. Not so long time ago I started noticing that Firefox starts randomly "freezing" when switching between tabs (most often) and clicking on links within webpages. I put "freezing" in quotation marks, because it's not really frozen - I can click on the tab and interface would respond, but showing new tab wouldn't happen. I made a video and shared it on Google Drive. https://drive.google.com/file/d/1IBVhYru58l5xlfkz7GrvYuscWqCoC_gH/view?usp=sharing

Few things to consider: 1) Bug present in both latest stable and beta versions 2) Bug still present in completely clean installation of Firefox, without any add-ons and not signed-in in the account 3) I use v2ray and Qv2ray to bypass internet restrictions of a country where I am currently at. It seems that "freezing" has to do with poor internet connection. Has anyone encountered similar problems?
