Hello,

I'm a regular user and I use 4 dozen addons to have mostly security features and a few other additional features.

Since no add-on can offer a toggle to change dom.event.clipboardevents.enabled within the GUI, I asked myself why. Some addon developer just mentioned briefly that it's not that easy to interact with the parameters of about:config.

Surely there are already dozens of concerns about this that lead to the decision of what is possible and what is not right now, but in this particular case it's useful - and some workarounds may be harder / heavier in code or may not be possible at all.

As soon as parameters of about:config can be easily changed, other add-ons could also use this feature and thus their code could be streamlined.

For example access to WebRTC, UserID or the Javascript setting or for accessibility.blockautorefresh, accessibility.typeaheadfind, app.shield.optoutstudies.enabled, browser.fullscreen.autohide, browser.newtab.preload, network.dns.disablePrefetch, pdfjs.disabled, network.http.referer.trimmingPolicy and many others that I didn't mention would be useful as addons to manage these on a site / tab basis!

So I would like to ask where to request something like this and how to properly fit it into the terminology that the moz:devs need to understand?

Many Thanks

I wanted to install Firefox in ReactOS and it seemed to be fine. I downloaded the version 48 from the ReactOS Package Manager and at the first start it said: "Update to Firefox 58 is available" and I clicked that totify. Then I pushed the button "Restart Firefox now" and a few seconds later Firefox 58 opened and everything workend fine... At least I thought it was like that: I wanted to log in to my Mozilla account and it opened the log-in page. It didn't load the page correctly but stayed forever on the white screen with the moz://a logo in the bottom left corner of the window and the blue loading circle in the middle. Than I let it sit there and came back about one hour later but nothing had changed. Then I tried to install a newer version manually but when I clicked on the installer *.EXEs ReactOS said "Not a valid Win32 application" or the Firefox installer said "Not compatible with this version of Windows". I really want to use the newest Firefox version on ReactOS (a legal Windows-imitating OS at the technical state of Windows Server 2003) but I couldn't find a way to do so.

Can anyone help me to install Firefox 89 or higher on ReactOS?

I'm using Firefox 90.0.2 on Manjaro and I have an issue regarding Picture-in-Picture mode. Whenever I put a video into PIP, the second I click on another window, be it firefox itself or any other program, the PIP window will move behind that program's window.

I use PIP all the time on Windows but I've never experienced this issue. It only happens on Manjaro.

Hi, Does someone know how to install Firefox on Ubuntu Touch ?

I did install "Ubuntu touch" on my smartphone few weeks ago.

But without my favorite Firefox Navigator, this is useless for me !

Even a older version of Firefox will be fine. All i need for now, is a Sync of my configuration (bookmarks and Passwords Manager).

Hi! I have the strictest anti-tracking protection enabled and have one question: Firefox prevents cross-site cookies by default, but if I install Firefox Containers, does that mean that those cross-site cookies will be allowed inside that container, even if they're not when browsing outside of any container? My concern is that, if that happened, using Firefox containers would actually diminish privacy instead of increasing it (for example, Facebook would be able to use Instagram cookies because they're in the same container, even though it wouldn't if I hadn't installed Containers). Thanks a lot! Love the Firefox community <3

My web page (HTML) has one embedded video (my own, uploaded to YouTube). The embedding code line is ...

and the error/warning I get when I open my page isL

Firefox Can’t Open This Page To protect your security, www.youtube.com will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window.

How do I fix this issue, please? Thank you Regards Fred James

It has been a while that gmail and whatsapp web version wouldn't load on Firefox. After some time researching I saw that my Firefox ESR storage are broken. Especially:

• QuotaManager
• Bad: Totally Broken. (fullyBroken)
• IndexedDB
• Bad: Totally Broken. (fullyBroken)
• Cache API
• Bad: Totally Broken. (fullyBroken)

Is there any way to fix this? I'm using Firefox ESR on Linux and it seems there isn't new Firefox ESR updates.

Hi all,

i'm currently developing an add-on that has an import from file feature that needs to open an "Open file" dialog, now the problem is that in order to do that i had to do the following:

• inject some javascript code in the active page as a content script
• call the execute command from the extension to open the dialog popup (that is actually emulating a click)

I have to do it, because from an extension when a "File open" dialog appear, the extension lose the focus and it is automatically closed, and its context destroyed, so when i actually press open on the dialog, the "caller" is already gone (https://stackoverflow.com/questions/26884140/open-import-file-in-a-chrome-extension/26917671#26917671 you can refer to my stackoverflow question to get an idea of what i was doing)

This works fine in chrome (And it worked for a while on firefox) but probably in the latest months/years (not sure when it happened) it stopped working and when i press the import button nothing happens, after some investigation i found what is the problem: the "block popup" windows option enabled by default (i suppose it is enabled by default i don't remember to have never enabled it), so when i disable it, the feature resume working. What i'm wondering is if there is a way to programmatically add an exception to the popup blocker option while installing the extension, or if there is any way to avoid closing the exception popup when the "File Open" Dialog appears.

Thanks everyone

Soy usuario de firefox con Ubuntu 18.04. En varias ocasiones al tener varias pestañas de navegación el equipo se bloquea por completo, solo es posible forzar el apagado con el boton de encendido. También creo que este problema lo tenia con Ubuntu 16.

¿Alguna sugerencia?

My title bar has a weird symbol in front of where it says Mozilla Firefox

Sort of looks like a yen symbol and the m of the Mozilla Firefox looks weird as well

Hello,

I updated firefox and it's now hard to tell when one tab ends and another begins when you have multiple inactive tabs next to each other, which is a major annoyance.

The way to solve this would be to have the inactive tabs have a border around them like the active tab, have them have a different background color from the toolbar, or otherwise have some kind of separator between them. I saw another answer that gave a temporary solution, but the same answer said the solution was going to stop working in a future update. Is there a permanent solution?

Hello,

At first I thought it was a tired Arch Manjaro install that was perhaps the issue. Now that I've done fresh installs of Arch (Manjaro & Arco), Ubuntu (KDE, Gnome, & XFCE) on both my workstation and laptop, I can say it's not my Hardware or OS. So why is Firefox crashing all the time? Mid chat conversations, etc. Again, fresh OS install and zero Add-Ons installed. I can't use Firefox, even if I badly wanted too when it tanks on me all the time.

when using firefox plugin PDF viewer (PDF.JS) display chinese content cause some issue, fontface and font doesn't display correctly. will this issue fix in next version?? tks.

Since I upgraded to Firefox 90.0, my RSS feeds can not longer be refreshed in my feed reader. I get a 403 error ("access denied"). When I check the debug information on the URL, it says:

Content Security Policy: The page’s settings blocked the loading of a resource at inline (“script-src”).

I am using Feedbro on Firefox 90 on Ubuntu 20.04 on two different computers, and getting same problem.

Clearing the cache, trying other feed readers, deleting cookies etc do not help.

A sample feed URL: https://news.google.com/rss/search?hl=en-US&gl=US&q=mozilla&ceid=US:en In Firefox, I can open a tab and see the text file. But Feedbro, or any other reader, cannot detect the feeds on this page any more.

Any advice? I absolutely rely on RSS feeds for my work.

Thank you kindly!

Debian Linux 5.10.0-8-amd64 #1 SMP Debian 5.10.46-2 (2021-07-20) x86_64 GNU/Linux

The following appears in the access.log:-

127.0.0.1 - - [28/Jul/2021:15:17:42 +1000] "POST /scripts_php/memb_login.php HTTP/1.1" 302 314 "http://dev.webtest.info/htmlpages/login.html" "Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0" 127.0.0.1 - - [28/Jul/2021:15:17:42 +1000] "GET /scripts_php/memb_login.php HTTP/1.1" 200 499 "http://dev.webtest.info/htmlpages/login.html" "Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0"

The form method is POST and the action is to call a PHP script which expects a POST array. The "302 314" appears to be correct, but, a GET is returned immediately.

According to w3.org:-

Note: RFC 1945 and RFC 2068 specify that the client is not allowed

     to change the method on the redirected request.  However, most
     existing user agent implementations treat 302 as if it were a 303
     response, performing a GET on the Location field-value regardless
     of the original request method. The status codes 303 and 307 have
     been added for servers that wish to make unambiguously clear which
     kind of reaction is expected of the client.

This has just started to occur after a recent upgrade to Firefox. It might be caused by the browser but there might be some other explanation or configuration setting that needs tweaking. Could somebody please help.

Thanks.

I got hello_xr to run but how does one view WebXR spaces by using the monado service for Firefox? I can still develop for captured mouse mode or use the WebXR API Emulator add-on but I still have not found documentation about how to get Firefox to talk to the HMD or its tracking system using monado-service. Thank you in advance.

Firefox become hopelessly show to play even 480p videos from youtube 90% CPU usage while playing 720p video from youtube freezing randomly. (same issue on other notebooks, so I have a strong feeling it is not a hardware/notebook related issue) Hardware:

• CPU: i7-6500U
• RAM: 8GB / DDR3
• Video: Intel HD graphics
• Memory usage never runs above 60%

OS: doesn't matter, experiencing same issue on windows 7/10 and linux.

to compare, same video 1080p/60Hz played with:

• brave/chromium ~30..35% cpu
• mpv playing same video directly from youtube ~ 19..25% cpu
• Firefox - constantly freezing, youtube autmatically switching from 1080p to 720p, then to 480p, playing 480p @ 60..90% cpu usage

I have tried everything from this forum and from others - nothing helped.

And finally, last nail in a coffin - even my very old notebook Core2duo with 2GB ram playing 720p videos with brave browser without issues while firefox struggling to play 480p, constantly freezing and making notebook fan run like crazy.

Firefox is literally forcing me to use other browser.

My install of Firefox was somehow corrupted. I was instructed by FF tech support to download the latest "Nightly" build, extract it to my "Downloads" folder, and launch it using the following command:

MOZ_ACCELERATED=0 MOZ_WEBRENDER=0 ~/Downloads/firefox/firefox

This opens a working install of "Nightly" (with purple & blue firefox icon), but as soon as I close it, the icon goes away. The program is not recognized as "installed" so it does not appear in a search for installed apps. And if I right-click on its icon while running, "Pin to taskbar" is not an option.

"Nighly" is working (I'm using it to type this) and I even have it Synced to my account, but the ONLY way to launch it is via the Terminal CLI. :(

My broken copy of "Firefox" is still listed as installed, but is unusable.

HELP! TIA
