I'm using Firefox 76 packaged with fedora 30 but it wont display a video (weirdly youtube does work). I'm getting the message: "this content requires adobe flash or HTML5 video support..." I don't want to install flash because I've seen some content somewhere about security concerns. I looked for an extension or add-on but none of them seem to be Mozilla approved and most of them don't seem to address this issue anyway. I can't find a setting to fix this in Firefox. I've seen an archived thread about this problem suggesting maybe some linux library issue, but it contained no solution. Maybe I'm missing something fundamental but it's 2021 now and I'd like my Firefox to support a bit of video here and there other than youtube. Has anyone got a solution?

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.

Problem with printing at reduced scale, did not notice it before a few days ago so could have been after a recent update. Am now using Firefox 90.0 for Linux Mint 19.3. Printing to US Letter size (which had been broken with "na_letter" being stuffed in to the config at one point, but I switched it back to "US Letter" and then it started working again a few months ago - Thank you).

I see some similar questions listed, so this may be simply adding information to something known:

Printing with "Fit to page fit" works fine, with correct preview. Print with scale set to 100% works fine, with correct preview.

Printing with scale set to less than 100% (say 70% or 80%) showed in the preview the page rescaled as expected. The actual printed output is also rescaled as expected, but the page size gets cropped at the right and bottom by what appears to be the same percentage, ending up with lost content. The bit that does print seems to match what is shown in the print preview perfectly, suggesting it would have been totally perfect if the print area had not been cropped along with reducing the text and image sizes.

I tried the "Print using the system dialogue" option, and the printed result had the same pathology.

Same problem also happens when I print to PDF. For this I tried doing the same thing twice, both scaled at 70%, and on comparing found that the preview in firefox had also become cropped a bit but not to the same extent. I did not notice any cropping for the first print to PDF, but now seem unable to get back to what I saw originally in the preview, with correct resizing and no cropping. Playing around some more with printing at 100% vs 70% vs 80% to "fit to page width", I seem to be getting changing crops happening each time in the preview for the reduced sizes.

But the preview and print are both still correct for 100% scaling and for "fit to page width".

Sample web page I used here was https://getpocket.com/explore/item/a-shoulder-workout-for-better-posture?utm_source=pocket-newtab The screen shot shows the preview after the first reduced print to PDF, with no settings changed. The little bit of side cropping seen in the preview did not happen when I did the first print to PDF.

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!

Using Apache2 to serve web pages.

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.

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

Hi! Some days ago I started experiencing problems to load Google service webpages. For example sometimes youtube tells that there is a connection problem, when loading gmail I get " has experienced a network protocol violation that cannot be repaired". When I use other browser I can access to that services with no problem. I am in linux, and I have tried disabling all the add-ons, starting in "safe-mode" and rebooting my computer. At the beginning everything works fine, but after some time starts failing. I have tried with different Firefox versions, and the problems persists.

I've only experienced this on Firefox, but while watching multiple videos/twitch streams, video playback becomes very choppy and laggy. Actually, firefox in its entirety becomes laggy. This is not a problem when using chrome/chromium, and my PC is more than powerful enough to handle this, with a rtx 2060 and an i5-10500. On chrome I've watched 4 streams on twitch at once with no issues, but on Firefox it starts becoming choppy with only 2 open. Anyone know how to fix this? I don't really want to use chrome anymore. I'm currently running Pop! OS 21.04, with Firefox version 89.0.2.
