Is it possible to disable automatic "word search"? every time i'm on a page and hit some letter key mozila opens the automatic "search keyword" without my wanting it. I want to open the "search keyword" only when I press crtl + f and never, never in automatic. it also hinders to play browser games, I can not play games because any key that I press the mozila opens the "search word"

Until several weeks ago, new windows created through Javascript with window.open() worked. We could pass the new size, and other features, e.g. menubar, toolbar, etc. and they would show up. As of v.76.0 this is no longer true. The parameters are ignored. If we use no parameters, the menubar, etc. do show, but we can't control any new window features. We have not changed our programs at all, and window.open() parameters still work correctly in Chrome, Brave, Edge, etc. How do we get Firefox to recognize the window.open() parameters (again)?

I am receiving too often the message "A Page is Slowing Down Your Browser, What Would You Like To Do?" It becomes annoying. I tried the same site with Edge and it responded faster. What can I do other than switch browsers?

Firefox doesn't show sent messages in Gmail. Neither individual sent messages nor conversations that include sent messages. The message lists display fine, but when I try to open a message / conversation it only shows a blank page. Currently the version of Firefox on this computer is 83.0 (64-bit), although the problem occurs since the most recent versions. It only happens with Gmail. Yahoo! and AIM work fine. Doesn't happen in Chrome or Edge

If I use my touch monitor when a video player is full screen, the full screen Firefox window turns grey and becomes unresponsive to mouse and touch input. I can exit full screen with Esc or F but the problem persists in full screen mode until I restart Firefox. Picture attached is my monitor when Firefox is in full screen mode.

Friends, I use FF extensively and prefer not to change but it's been very annoying as of late.

Running v83. Even downgraded to v82 and it worked for some minutes but now it's back to same behavior. [struggle to download to 82 is here: https://rezamusic.yolasite.com/technical-tips.php]

If you google "squeeze lemon" for example -- on my Chrome it shows images and a list of drop down subjects "people also ask".

On Firefox, the pictures don't show -- and drop downs are frozen (don't work). Also on other sites that have a Captcha, Firefox just doesn't work. Seems same problem with 82. Help!

Images are from Chrome -- and last one from Firefox

Hey there,

I have the following issue with Firefox, is this maybe something I should report to the Ubuntu support or directly to Bugzilla?

Steps to reproduce: ---

1. Open Firefox
2. Go to a page that contains an embedded video that is not playing automatically, e.g. https://www.rottentomatoes.com/m/sound_of_metal
3. Do not play the video

Environment --- User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:83.0) Gecko/20100101 Firefox/83.0 Firefox version: 83.0 (64-bit) pulseaudio version: 13.99.2 OS: Ubuntu 20.10 64-bit Gnome version: 3.38.1 Windowing system: Wayland CPU: Intel® Core™ i7-8565U CPU @ 1.80GHz × 8 RAM: 15,5 GiB GPU: Mesa Intel® UHD Graphics 620 (WHL GT2)

Actual results --- pulseaudio process is spawned and rapidly becomes the most CPU consuming process on my machine (especially after a few seconds, when the Web Content ones start to cool down). Even though no sound is actually played! When switching to another tab with no embedded video, pulseaudio keeps overloading the CPU. This only stops after closing Firefox.

Expected results --- I'm not sure this is what should be expected, but I'll give it a shot:

• pulseaudio process should only be spawned when actually playing a media that requires audio
• pulseaudio should not be the #1 CPU consuming process
• pulseaudio process should at the very least not massively use CPU when no sound is playing

I love having the Clear Cache icon so easily accessible, but why must it also refresh whatever page I am on??? Just now it caused the page to revert to one that had none of the articles on it, I was just looking at! This is supposed to be a helpful feature, not one that screws things up.

Hi, first of thanks for reading and possibly responding.

The issue I am having has been going on for a few days. In websites where youtube video's are embedded if I try and play the video on the said site it will load and display an error message An error occurred. Please try again later. If I visit the video on youtube, link provided in the video itself, then it plays just fine. Error is not restricted to one site but anything that embeds youtube videos.

I have also come across some strange youtube.com issues, when I am on the main website you get the thumbnails of video's but no time duration are displayed in the thumbnail, neither are the 3 dots where you can have one of the videos removed (not a big deal and maybe this was implemented a while ago I don't know tbh). When I play a video, as in visit the video page on youtube the side bar videos sometimes do and sometimes don't display time duration.

Please check attached image to see what I mean. Left is without said timecodes, right is what it almost should be.

What addons do I use: Ublock Origin is the only one worth noting but even without it the weird thing still occurs. I don't use any plug ins that correspond with youtube.

I am using the latest Firefox on Windows 10.

Things I have tried thus far to resolve it: - make sure Firefox is up to date - try with and without addblocker (Ublock) - remove Adobe flash entirely - refresh Firefox and clear all data and cookies 9tried this I think 3 times now, no change) - looked through older posts with similar issues but most links regarding html5 on youtube were 404 and sometimes the solution stated things like 'cause by some video helped addon' which I do not use or updating Flash

Am I the only one with this issue?

Firefox has a "list all tabs" button, which looks like a "v" in the tabs bar, next to the plus. It works great but when I maximize the window (not F11 full screen, but Windows OS Maximize Window), this button disappears. Seems like a bug; I can't think why you would want that button to be removed when the window is maximized.

On screen keyboard not working when using Firefox. It will work with MS Edge, but not Firefox. It flashes then disappears quickly when in Firefox. It worked previously, but a few months ago it quit working.

Hello, I have trouble getting sound playback on firefox (checked 85.0 and 78.7.0esr both 64 bit) on windows 10. I checked sound on youtube, and netflix. I checked other applications like spotify and mpv, and soundplayback there is fine. Also it works on Firefox nightly (87.0a1).

What i have already tried: - restarting my computer - opening windows volume mixer and see if firefox is muted - updating my audio driver - different playback devices (Device over HDMI and Line out) - reinstalling firefox - uninstalling firefox, delete folders in C:\Users\$username\AppData\Local C:\Users\$username\AppData\Roaming - new install with fresh downloaded installer - restart to safe mode

Since firefox nightly is working i suspect that maybe the application name "Firefox" is muted somewhere. This could explain why i can reproduce my error on ESR and stable but not on nightly.

Thank you for your help in advance

I can not press the "Backspace" on YouTube using Firefox, but my keyboard works fine cause in Chrome and Edge it works perfectly, I've already refreshed the tab and still not working. Have any idea of what's going on?

Why Firefox Taking Resource Without Even Opening Multiple Tabs ,At Startup Browser Starts With 60-70 CPU Usage And Even If Close The Browser It Still Takes 60-75 Until I Close It From Windows Task Manager,Attached Some Screenshots Check It You.

This has been going for a couple of days.

I have tried starting in safe mode, didn't help.

I have tried disabling JavaScript, didn't help.

Two "main sites" affected, Feedly and Gmail. Feedly had this problem but it disappeared after a while. Now Gmail is having problems. I can move around and read mails but not respond to them.

Other sites affected "seems" to have in common that they are blog-type, perhaps like WordPress or similar.

I have a Windows 10 computer with the same browser setup and there have been no problems there so far.

The version is 86.0.1 (64-bit).

I'm not technically advanced so please be gentle with me.

Hi,

I think I broke the ALT keyup events in some way, probably with my configuration but not sure how.

If I put this code in the console : `document.addEventListener("keyup", e=>console.log('alt: '+e.altKey+' | '+String.fromCharCode(e.which).toLowerCase()));` and the press the keys, I have the following results:

- pressing "I", I get the expected "alt: false | i" - pressing "ALT+I", I get "alt: true | �"

I do not have the problem with other modifier keys like CTRL

Hello to all,

as I am running out of ideas (see all actions already taken below ...) I wonder if the community has any idea what might be the solution? Forum search here did not reveal any entry with my particular circumstances as it affects only the current user account on my computer.

My Firefox profile folder is rather old as some of the files in its three different profiles date back to 2005. The whole Firefox folder has been migrated from two previous Macs to the current machine which itself now uses its third hard drive. Therefore a folder rights issue might be possible but in my opinion not very likely.

As I am used to report software bugs I have chosen to write it down like a bug report, so mea culpa if this is not the expected format on this platform. But I am a little desperate and miss my highly customised Firefox environment.

Best regards from Berlin/Germany and many thanks in advance

Carsten

Describe the problem you have:

"Firefox" no longer launches successfully, claiming that there is no profile. However, the profile folder has not been manually renamed, moved or modified.

If possible, include steps to reproduce the problem:

- Start Firefox program (Dock, Finder, commend line) - Error message appears immediately

Expected behavior:

- Program launches with all data and settings from the profile folder.

Observed behavior:

- Error message: "Profile not available. Your profile "Firefox" cannot be loaded. It may not exist or access is not possible."

Program version: - Firefox 78.8.0esr (System language: German, de-DE)

Platform: ProductName: Mac OS X ProductVersion: 10.14.6 BuildVersion: 18G8022

Please provide any additional information below: - Program was deleted and reinstalled: Firefox again starts only with error message

- tried all steps from "https://support.mozilla.org/en-US/kb/how-run-firefox-when-profile-missing-inaccessible" with no success

- tried to start in safe mode: "/Applications/Firefox.app/Contents/MacOS/firefox-bin -safe-mode" with no success

- tried same computer, user account of local admin: Firefox starts without error message

- tried same computer, user account of another standard user, copy of Firefox profile folder pasted to appropriate folder: Firefox starts without error message with almost all data and settings. Missing: different GUI theme and all Addons icons in the toolbar

- tried with separate ProfileManager.app: regardless of any selected checkbox, the same error message is always displayed
