Low fps on multiple iwndows hen one is playing audio or video

OS: Ubuntu 21.04 x86_64 CPU: AMD Ryzen 7 3700X (16) @ 3.600GHz GPU: NVIDIA GeForce RTX 2060 SUPER

When I have two windows running and one of them is playing either audio or video on its active tab, the other window runs at a very low FPS. This is noticeable when scrolling, as CPU usage appears to increase dramatically while monitored.

The problem does not appear when running firefox in safe mode, but I cannot determine what might be causing the problem when firefox runs normally: the problem persists when I disable all extensions, as well as when I use the browser's default appearance as opposed to the theme of my choice. As far as I can tell, I have not modified any about:config settings either, although some cursory searching online suggests webrender may be a cause.

When I view Morningstar charts, such as the one at: https://www.morningstar.com/funds/xnas/vfiax/performance on my Microsoft Surface Go (Windows 10), in Firefox 93.0 and some previous versions, the legend does not display the line colors for the investment, category and index. The page is displayed correctly in Firefox 93.0 on my Desktop Windows 10 system, and when using Microsoft Edge on the Surface Go. Any suggestions?

I have used firefox for many years and really like it overall. One real problem is not being able to open new tabs to my home page (or what ever page I define to open). I have contributed to the project several times over the years but I am considering a replacement because of this issue. My hope is you might provide some solution without an addon, which always brings overhead. Please advise. Joe

My 11-year-old PC (custom build, now running Windows 10) crashed badly (hard drives and Windows 10 were irretrievably broken), so I bought a new motherboard, etc. and installed a new OEM copy of Windows 10. I must reinstall almost all software, including Firefox. The old C: drive SSD is intact. After I install Firefox on the new machine, how can I restore the tabs from the last Firefox session?

While there are some things I like about FireFox, I use another browser for the vast majority of my browser use... I'm running Linux, and it seems that FireFox has locked itself in as the default browser... Since I am unable to modify that condition, is my only recourse to uninstall FireFox? Or, am I missing some secret handshake?

When I got my Android phone, sync (from desktop to phone) worked nicely. My laptop was permanently damaged in a fire, and my latest backup of FF folders is two weeks old. (I'm guilty - I know!). Bookmarks still appear on my phone, including a few I added just hours before the fire. If I log into FF on the new desktop, will it pull all the bookmarks from the phone? Or will its brand new (and empty) bookmark file tell the phone to dump its bookmarks too?

In other words, who's in charge in a situation like this? The desktop or the phone?

Hi, I just would like that whenever I open the browser, it would open my saved homepages. If I turn off the computer without closing firefox then the next time I open the browser it will load my previous session. I dont want to load my previous session, I want it to open my homepages every time. I have already unchecked "restore previous session" in the options. It only works if I close the firefox before turning off the computer. Just, please, tell me which option I should uncheck in about:config.

I have set a number of pinned tabs and leave a few other tabs always open. I set Firefox to restore the tabs when I close it and reopen it. Most of the time I have just one Firefox window open and this works fine. Occasionally, however, I need to open a second window usually with just one tab and if I forget and close the main Firefox window with the pinned tabs, etc before the single window one, Firefox reloads this single tab when I reopen it. Is there a way to avoid this behaviour?

Hi all,

I am a Linux user (Manjaro) and I've been using Firefox for ages now. I got hold of another computer recently, and I just installed Manjaro Gnome on it as well. I started Firefox, and suddenly I see a UI change, which I don't think is an update, but who knows. In this version of firefox the search bar (along with the new tab, refresh, pocket, etc buttons) are abobe the tab list (which spans the full width). You can see it here https://imgur.com/a/idqp5jb

Moreover, i tried changing themes via the Add-ons Manager and they can't be applied.

When using the Troubleshooting mode, Firefox is back to normal! But in normal mode it is not, so I am not really sure what the problem is. I would be thankful if you could tell me how to fix this.

How can I get the english wikipedia back instead of the search page of the infamous sleazy big company?

My distribution updated Firefox from 78.13.0 esr to 91.2.0 esr.

At each larger update Firefox deletes the search engine for the English language Wikipedia -- maybe because my interface languge is German and I have the German language Wikipedia installed. Up to now it offered in the search field to add the English Wikipedia when I was on this page. But not anymore.

Hello,

I have the current Firefox version (93.0) running on XUbuntu 20.04.03 LTS. Accidentally pasted the URL of a known phishing site (obtained from Phishtank) into the address bar instead of a VirusTotal search box, and it browsed to the site. Verified in https://transparencyreport.google.com/safe-browsing/search?url=https:%2F%2Fdocs.google.com%2Fforms%2Fd%2Fe%2F1FAIpQLSeAhelw8U_QuFyvJDmAn4aYM-H6QXYahD7ZjaFXC6CdyuxaNQ%2Fviewform%3Fusp%3Dsend_form&hl=en that the site is blacklisted.

I thought that Google Safebrowsing is enabled by default? (Checked about:config and saw that the "safebrowsing" settings that are bold are the ones with timestamps e.g. lastupdatetime and nextupdatetime.)

After the latest boot-up on my Manjaro desktop, Firefox is compeletely mute. All other applications are producing sound as normal, it's just Firefox that's gone silent. Checked the mute settings on the individual tabs, Checked the speakers, checked the linux system settings, checked ever volume control I can find, still no sound. I'm stumped. As far as I can tell, there's nothing telling Firefox to keep quiet, it just is for some inexplicable reason.

I created a tar.gz back-up of my /home folder prior to doing a fresh install of UbuntuStudio 18.04. (The previous version was Ubuntu Studio 16.04, and it wouldn't let me upgrade, so I had to do a whole new installation.) I never "exported bookmarks" because I never realized I could do that! However, I was sure there must have been bookmarks already kept somewhere in my /home folder. However, now I can't figure out how to get at them. Although I can extract all kinds of files dealing with Firefox, I can not figure out how to access or generate Firefox bookmarks from all those files that exists. I'll try to attach a photo of my terminal output for what I can extract from the old /home that had "firefoxbookmarks" in it's name. Can anyone please help me.

But in case it doesn't upload here is my terminal output: usr/share/unity-scopes/firefoxbookmarks/ usr/share/unity-scopes/firefoxbookmarks/__init__.py usr/share/unity-scopes/firefoxbookmarks/unity_firefoxbookmarks_daemon.py usr/share/dbus-1/services/unity-scope-firefoxbookmarks.service usr/share/doc/unity-scope-firefoxbookmarks/ usr/share/doc/unity-scope-firefoxbookmarks/copyright usr/share/doc/unity-scope-firefoxbookmarks/changelog.Debian.gz usr/share/unity/scopes/web/firefoxbookmarks.scope usr/lib/python3/dist-packages/unity_scope_firefoxbookmarks-0.1.egg-info var/lib/dpkg/info/unity-scope-firefoxbookmarks.md5sums var/lib/dpkg/info/unity-scope-firefoxbookmarks.list usr/share/unity-scopes/firefoxbookmarks/ usr/share/unity-scopes/firefoxbookmarks/__init__.py usr/share/unity-scopes/firefoxbookmarks/unity_firefoxbookmarks_daemon.py usr/share/dbus-1/services/unity-scope-firefoxbookmarks.service usr/share/doc/unity-scope-firefoxbookmarks/ usr/share/doc/unity-scope-firefoxbookmarks/copyright usr/share/doc/unity-scope-firefoxbookmarks/changelog.Debian.gz usr/share/unity/scopes/web/firefoxbookmarks.scope usr/lib/python3/dist-packages/unity_scope_firefoxbookmarks-0.1.egg-info var/lib/dpkg/info/unity-scope-firefoxbookmarks.md5sums var/lib/dpkg/info/unity-scope-firefoxbookmarks.list

I am using Firefox 93.0 on Archlinux, with Kde Plasma 5.22.5 and since yesterday a very strange issue is happening.

Only when I use my Firefox' Work Profile, the mouse cursor hitpoint is misaligned from the tip of the pointer.

For example, for the arrow cursor, the hit point is on the left a few pixels below the arrow tip. For the text caret cursor it is even worse as the hit point lies outside the cursor itself, about 5 pixels below.

This happens not only within the pages, but also on the tabs, bookmarks, tabs, menus and even the settings page, as can be see in the partial screenshot attached. As per the cursor position, the "Advanced" button should be highlighted, but "Colours" is highlighted instead.

This DOES not happen with any other program on the same linux session and not even on firefox when using my private profile.

I have tried disabling extensions, but that did not change anything.

I am not even sure where I can start investigating or troubleshooting this, appreciate any suggestion. Thank you.
