Forum der Gemeinschaft Firefox

I did some googling first and it seems to be an on and off issue mozilla has had with years. Anyway, whenever I play a video (be it youtube, twitter, instagram, even gifs on twitter actually) the video will often mess up and become a chaotic jumbled garbled up mess of green with junk artifacts over the video. The audio will play fine. It's like watching a scrambled TV station from a 90s bootleg cablebox, but green.

This issue doesn't exist in any of my other browsers.

I'd love to continue supporting Firefox instead of Chrome, but this is a persistent issue across the entire internet, so it's kinda obvious I need to stop using Firefox until this is patched. Thanks.

Today I was no longer able to stream movies on Amazon Prime or Youtube. I watch Amazon movies most nights, watched last night. Tonight I got a message when I tried to continue watching a tv series on Amazon that I've watched for weeks. It said I had to update Firefox and told me how, but when I went thru the process Firefox said it was up to date. On Youtube I got an error msg. 99,999 . What is happening?

I often receive a 403 error when using Firefox Every time, before this happens, I get the unsafe website warning and then the 403 error when I continue anyway

I am using the latest version at the time of writing These errors only occur on my desktop PC I have tried to replicate this issue on both my phone (Android) and another laptop(Windows 11) but all the websites work normally on there.

I have tried the following, none of which have any effect:

• Clearing cookies
• using Troubleshoot mode
• Restarting
• Changing Useragent
• Using "Forget about this site"

The following do fix the issue

• Using a VPN
• Using Google Chrome
• Running Firefox in another profile

Going through the privacy and security tab and reseting all the settings sometimes works but only temporarily

The following are a few websites where the issue occurs

I am so frustrated. Although I'm relatively computer literate, I cannot find a way to stop that sidebar from opening up on Firefox Browser 133.0. I'm using Windows 11 Pro. I can find no button that allows me to either delete it or prevent it from opening. For heavens sake, not everyone wants all this stuff. I just want a great browser with minimal things to have to deal with. It is irritating to have to deal with this when there appears to be no simple solution to get rid of it. I do not feel comfortable with having to try to delete a profile element. Just give me the button to say I don't want it showing up when I open Firefox on my computer. It can't be that difficult. I use the menu bar at the top of the page to deal with bookmarks. I don't need a sidebar. Give me the option to get rid of it. It will always be there to hit the button on again if I choose to but I know I never will. It interferes with my page. If it isn't fixing something that is broken, and you want to try new things, fine. But give me the option to delete it from my experience.

When open Google Drive using Firefox, I cannot click on any documents. I can open folders but the documents in these folders I cannot open. I can open Google Docs and then access documents but all documents through Google Drive including in the Shared Folder are greyed out and when I click on any of these I get the pop up "This file cannot be opened because you're offline." I can access Google Drive and its documents using Chrome. I would prefer to use Firefox.

I have updated Firefox, cleared the history, and emptied cache and cookies. I also logged out of and then back into my gmail account.

The image shows what the drive looks like when opened in Firefox.

After updating to v 133.0, when maximizing Firefox (not F11 fullscreen), a taskbar that is set to "auto-hide" will no longer unhide when mousing to the bottom of the screen. This did not occur with the previous version (132.0.2).

This behavior is also unaffected by the "devtools.toolbox.alwaysOnTop" setting in about:config as i've tried switching from the default "true" to "false".

Update: Still persists in 136.0.2

My laptop (a Lenovo Ideapad220s) did an automatic Windows 11 update (I believe it was the 2H24 update). After that Firefox (version 133, 64 bit) would only open with the message "Gah. Your tab just crashed". Nothing I tried has worked, not any of the remedies found in support pages. I somehow did a Firefox software update and it shows as a separate icon and has not migrated any of the passwords and bookmarks I had in the software version that keeps crashing (my default browser). Trying to get access to the encrypted passwords to the many sites I've got with Firefox I opened the browser in troubleshooting mode. In this mode I have access to all the passwords saved over time, and the browser seems to work fine.

Any suggestions on what I need to fix or if this is related to the Windows update? I'd like not to have to go through the two-step process to use the browser.

Thanks!

My Firefox on windows 10 crashes tabs OFTEN. Mostly is seems to be Facebook and YouTube tabs, but other tabs will crash and this morning, the Firefox start page tab crashed. I've done "refreshes", I've uninstalled and deleted the folder and re-installed, I've checked the SSD for errors. Nothing appears in the event viewer. Is there some way to definitively figure what is causing this?

I am getting Secure Connection failed Error code: PR_END_OF_FILE_ERROR is there a way to bypass this. I tried 5 suggestions on YouTube and followed FireFox's directions for Avast, with no success.

Thank you in advance for your assistance.

I thought it was an issue with my pc, but chrome does not have this issue and neither do other applications. I have tried clearing my cache and cookies as well as ensuring mozilla was using my computer performance settings as opposed to hardware acceleration. The attached images are a very small example of the issue. Typically, after clicking on the screen or pressing a button the text is corrected but often replaced with new text being "corrupted". Any help would be greatly appreciated.

Since new update was installed today, in touch screen mode, every time a touch a link of any kind my touch keyboard pops up. This is very annoying. Where can I find the setting to turn off this option?

In the last few days, after some minutes of usage, parts of Firefox become unclickable:

- I can still click on tabs to change tabs. - When hovering over the cross button to close a tab, it changes appearance as it should. Clicking the button does nothing. Ctrl+w still closes the button. - Clicking on the address bar does nothing. - Cannot click on back, forward, refresh buttons. - Cannot click on any add-ons. - Cannot click on preferences. - Can click on the button to open a new tab. There, I can enter an address. Once the page has loaded, address bar becomes unclickable again. - Bookmarks toolbar is still working as expected. - Keyboard shortcuts (ctrl+t, ctrl-w, ctrl-l) still work as expected.

I'm running ``` Mozilla Firefox 138.0 20250428130755 20250428130755 ```

on Manjaro 25.0.1 with GNOME 48

Hi,

I'm developing a website that needs to authenticate with an external endpoint. Once authenticated, the website receives a session cookie that it uses for subsequent API requests.

I've configured the CORS headers on both Apache and Nginx, but I can't get it to work in Firefox. Interestingly, the same setup works perfectly in Google Chrome.

Here's an example of the headers I receive using a curl call:

curl -X OPTIONS https://crlliria.moval.es/web/session/authenticate \ -H "Origin: https://gis.moval.es" \ -H "Access-Control-Request-Method: POST" -I -k

HTTP/1.1 204 No Content Server: nginx Date: Wed, 04 Dec 2024 10:23:24 GMT Connection: keep-alive Access-Control-Allow-Origin: https://gis.moval.es Access-Control-Allow-Credentials: true Access-Control-Allow-Methods: GET, POST, OPTIONS, PUT, DELETE Access-Control-Allow-Headers: DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range Access-Control-Max-Age: 1728000 Content-Type: text/plain; charset=utf-8 Content-Length: 0

Despite these headers appearing correct, Firefox throws the following error:

"Credential is not supported if the CORS header ‘Access-Control-Allow-Origin’ is ‘*’."

I know the Access-Control-Allow-Origin value is not * (it's set to https://gis.moval.es), so this message might not reflect the real issue. However, I can't figure out how to debug it further.

Questions:

Is there anything specific about Firefox's handling of CORS and credentials that might cause this issue? Are there tools or techniques I can use to diagnose the actual problem? Could there be a subtle discrepancy in the request or response that Firefox is stricter about compared to Chrome? Any help or suggestions would be greatly appreciated!

Thanks in advance.

bold text Hmm. We’re having trouble finding that site.

We can’t connect to the server at www.googleadservices.com.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

Along with many other Firefox users, I have a long-term problem with a PR_END_OF_FILE_ERROR in Firefox. How can Mozilla Support fix this problem for me? Can you send a link with the solution, or something?

Thank you, Joseph Seecchack, [edited] @aol,com. I eagerly await your response.

Running Firefox 133.0 on Ubuntu 20.04 desktop

Periodically, Firefox will freeze and send the message "Firefox must be restarted to continue". After restarting, Firefox takes a long time to recover. This morning, it took nearly 5 minutes to recover.

I am trying to fix Firefox performance issues. I recently changed to Firefox to escape forced ads on chrome and the lost support for the Ublock origin. But I am having difficulty performing tasks and pages That I used to be able to do on Chrome with no difficulty.

When I open multiple tabs at once the tabs freeze up when trying to load and already opened tabs freeze and anything streaming also freeze. It takes tons of time to load multiple tabs and even sometimes single tabs depending on the website. This never happened with Chrome and I understand Firefox is not as refined as Chrome and is far younger than Chrome is but I feel like it shouldn't be this bad. Is there any settings maybe or maybe settings/preferences in the config area area that might help with faster performance and increased multitasking ability in the Firefox browser?

I have tried

1. Updating Firefox - I am running the most up to date version 2. Updating Graphics Drivers- I am running the most up to date drivers(Updated yesterday 11/17/2024 3. Deleting Cache/History/Logs 4. removed or disables unneeded extensions that I don't use every day and only activate when I need them.

None of this has worked to increase performance.

P.S. I would also like to fix the problem where firefox is using too much RAM if possible.

Can anyone help me Please? And if possible please give as many solutions as you can find or know so I can implement them quickly.
