RSS feeds broken - content security policy issue?

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!

POST action turns into a GET, which is incorrect.

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.

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

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.

According to various help articles, I should be able to export my logins and passwords using the Settings- logins and passwords and then click on the three dots in the upper right. That should display a menu with an option to export. In my case, when I click on the three dots I get only these options: Preferences, Help, Lockwise for Android, Lockwise for iPhone/iPad. There is no option to export anywhere on the page. How can I backup and logins so that I can load them on my new computer? As above, Firefox version is 72.0.2 and I am using Linux Mint 19.3.

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.

Are those buttons (behind the "page actions" one) supposed to be definitively absent from version 90 on?

They seemed to me one of the most intelligent features in Firefox interface. Some can be added under "customize" option, but copy link and pint tab are not.

Is this removal based on the idea that addons are supposed to provide the same actions anyway?

Sometimes when I start Firefox maximized. The whole window has an offset on the display (to the mouse).

So you have to click as if the window would be over the full display height, but it starts lower.

Clicking on windowed, does correct the problem, then you can maximize again (Which also works)

Hello everyone,

I believe I asked this about a year back, and the answer is that is wasn't possible.

I would like a specific behaviour on firefox. That, whenever I open it, it does the exact same thing. It opens a single new window. That it never ever tries to restore the last session. That it always starts fresh.

Preferably even if it "crashed", I tend not to close the browser but shut down with the tabs and apps open.

Intuitively this sounds to me like it should be easy to set, but I haven't been able to find a way.

Also, if possible I would like the rest of history to work. I find that history is useful, it's the session specifically I'd like it to forget / not try to resotre.

Thanks,

Sashin
